L0 indicates that CHS has Charpy V-notch impact properties as specified in AS 1163. Table 10.4.1 of AS 4100 Steel Structures permits AS 1163 L0 grades to have the following minimum permissible service temperatures:

Red Painted - Availability: 21.3 to 165.1 mm.

A smooth, even coat of a red, general purpose paint is applied to the external surface to act as a temporary rust preventative. The paint coating is 6 to12 microns DFT. This temporary coating should be removed prior to powder-coating or the application of coating systems intended for corrosion protection or architectural finishes. It is easily removed with any of the commercially available solvent based paint strippers, also usually removed as part of the available pre-treatment (caustic bath) system used in the batch hot dip galvanizing process.

The resultant steel surface from the manufacturing process prior to the red paint being applied is of better appearance than AS1627.4 Class 1. OneSteel strongly recommends that you check with your coatings manufacturer or supplier whether any additional surface preparation may need to be carried out on the pipe surface, prior to the application of any paint primers, top coats or special finishes.

Black (Clear Coat) - Availability: 21.3 to 60.3 and 168.3 to 457.0 mm.

A smooth, even coat of a clear polymer as a temporary rust preventative is applied to the external surface. It is easily removed with any of the commercially available solvent based paint strippers, and is normally removed prior to galvanizing as part of the available pre-treatments (caustic bath) used in the batch hot dip galvanizing process.

Black (Uncoated) - Availability: 76.1 to 165.1 mm.

Both the external and internal surface of the tube is supplied in the as rolled condition without protective coatings.

No Oil or Paint (NOP) - Availability: 21.3 to 457.0 mm.

Both the external and internal surface of the tube is supplied in the as rolled condition without protective coatings.

BENDING

®

DuraGal

DuraGal is readily weldable. Its thin evenly applied galvanized coating ensures minimal welding fumes. However, welding of any metal products can be injurous to health unless sensible welding practices are used. The ventilation recommendations given in Table 17.2 of Technical Note 7 published by WTIA (Welding Technology Institute of Australia), July 1994 should be observed. Mechanical dilution ventilation is advised for open work space and mechanical ventilation by local exhaust system for limited work space and confined space.

In addition, the “Fume Management Guidelines” which are available from the WTIA web site at www.wtia.com.au are also recommended.

DuraGal’s carbon equivalent of less than 0.39 allows it to be welded in accordance with AS/NZS 1554.1 Welding of Steel Structures, without preheat. The following are recommended consumables:

Here are some guidelines on bending of CHS, SHS, RHS and profiles (angles, channels and flats). Best results are dependent upon the type of equipment, the quality of the formers, the centreline radius, the speed of bending and the thickness of member.

Draw Bending Using an Internal Mandrel - CHS, SHS & RHS If the appearance of the finish bend is all important, particularly if no flattening or distortion of the product is desired, cold draw bending using an inner mandrel is recommended for CHS, SHS and RHS. This method can achieve bend centreline radii as low as 2 times the outside diameter (do) for CHS and 4 times the section dimension (d or b), in the plane of bending, for SHS and RHS.

Press Bending or Draw Bending Without a Mandrel CHS

Submerged Arc (AS 1858.1)

W502Y

Flux-Cored Arc (AS 2203.1)

W502X.X

If a little distortion can be tolerated the cost of bending CHS can be reduced by draw bending without the mandrel or press bending. Both these methods can achieve bend centreline radii of 4do to 5do for the lightest wall thickness pipe. Heavier wall CHS can be bent to tighter radii with minimum distortion.

Tubeline

Roll Curving - CHS Information received from specialist benders, using appropriate profiled rolls, has shown that bend radii from 100 mm on 26.9 OD to 1500 mm on 219.1 OD are possible.

As detailed in “Chemistry”, Tubeline® & UltraPipe® CHS and Tubeline SHS/RHS are readily weldable in accordance with AS/NZS 1554.1 Welding of Steel Structures.

For more information contact the Roll Bending companies in your area.

The following are recommended consumables for welding Tubeline® & UltraPipe® CHS and Tubeline® SHS/RHS:

SHS and RHS can be economically bent by roll curving. Some distortion of the section will result using this method. If a flat roll, 3 roll bender is used, OneSteel Market Mills does not recommend bend centreline radii less than 30 times the depth of section in the plane of bending. If the 3 working rolls are profiled to suit the section being bent, bend centreline radii as low as 10 times the depth of section in the plane of bending can be achieved with reduction in section stiffness (Ix) of less than 10%. The Actual values should be confirmed with your Roll Curving company as facilities and equipment may vary between companies.

PAINTING

The following table sets out the known results of roll bending profiles:

DuraGal® / Galtube Plus® The most cost effective way to use DuraGal® and Galtube Plus® products is unpainted, touching up any welds and black attachments.

When painted or powder coated, the result provides enhanced surface protection. Authoritative research has shown that by teaming the inline hot dip galvanized coating with paint a synergistic effect occurs, ie. the corrosion life of duplex coating system can be 1.6 to 2.3 times greater than the sum of the corrosion lives of the zinc and the paint used separately.

For weld touch-up, If DuraGal® / Galtube Plus® is to be used without topcoating, weld protection through the use of a zinc rich primer or epoxy mastic applied to a suitably prepared surface willl be sufficient for most applications. GALMET® “DuraGal Silver Paint” or any other equivalent colour matching paint may be used as a top coat for colour matching.

If the DuraGal® / Galtube Plus® system is to be topcoated for exposure to more severe environmnets the weld areas should be adequately protected according to the coating manufacturers recommendations prior to topcoating.

Channels bent on edge collapsed during the rolling process. It was thought that adding support rolls between channel flanges would stop this crushing failure and would allow successful roll bending.

Some environments cause especially rapid corrosion. They include industrial areas, marine environments, polluted cities, some farming activities, animal husbandry and other corrosive environments.

There was some minor scuffing/pick-up damage to the galvanized coating during roll bending, particularly on the edge of angles. The scuffing can be minimised if the rolls are smooth and hard.

Refer to the “DuraGal® Painting and Corrosion Protection Guide” available from OneSteel Market Mills for detailed recommendations on painting of DuraGal® and Galtube Plus® products.

The galvanized coating should not flake off the steel substrate but some peeling due to mechanical pressure or rubbing can occur.

Crush Bending - SHS & RHS Tight radius SHS and RHS bends can be formed by crush bending, often using the press bending technique. This method of bending dramatically reduces the sectional properties of the hollow section and is therefore only suitable for applications which are non loadbearing, or lightly loaded, unless the deformed section is stiffened.

PRODUCT INFORMATION

WELDING

BENDING - Continued Ram Bending - CHS Testing has shown that good bends can be made in CHS up to DN50 using a well maintained, simple ram bender. It is critical that a suitable former be used. If the former being used fails to bend cold formed ERW pipe, it is usually because the former does not give good support to the pipe during bending and/or the bend centreline radius is too small. There is a range of suitable formers available from most Merchants, as set out below.

If the bend is still collapsing when the support rollers are at the suggested centres then check the condition of your former. If the former is damaged and/or badly worn bend failures may occur.

When bending CHS at these support pin centres it will generally be necessary to use a pivoting support block which is grooved to the OD of the tube being bent.

Recommended Weld Position

An alternative range of formers is available from Dawn Tool & Vice.

Because these formers are made from ductile iron, the surface finish of the completed bend is not as good as that achieved with the preferred formers.

OneSteel has not tested Ram Bender Formers for CHS sizes larger than DN50 (60.3mm outside diameter) but this does not mean that the larger pipes can not be bent by this method. The difficulty of bending pipe increases as the outside diameter to thickness ratio (do /t) increases. OneSteel has successfully bent pipes with a do/t up to 27.4 (i.e. 60.3/2.2 = 27.4)

* Contact number for Dawn Tool & Vice: (03) 9462 1934 The Right Former The most critical element is the former. It must give the pipe adequate support. Good results can be achieved from the simplest of benders if suitable formers are used. Three types of formers exist, each giving the bent section a different profile.

Circular: Pipe generally falls to the bottom of the former. Absence of side support could result in pipe collapsing on bending.

(Not recommended for Light or Extra-Light pipe)

For best results, the weld should be touching the former in the shaded area, with the ideal weld location in the 3 or 9 O’Clock position.

Problems encountered with ram bending.

Flattening / Collapsing / Wrinkling Possible causes The former is worn or the former does not adequately support the pipe.

Alternatives Try a former with an ellipitcal or cathedral profile to increase the side support, (recommended for Light and Extra-Light pipes).

Go to a larger bending radius.

Move the supports closer to the centre.

Try a different bending technique.

Try a heavier gauge pipe.

Effect of Bending Former profile Using the Elliptical and Cathedral formers tabled in this section, a series of ram bending trials were performed on OneSteels’ Tubeline® & DuraGal® Extra-Light (350 MPa) CHS, sizes DN 20,25,32,40 & 50.

With conventional (circular profile) formers this range of pipe would typically be expected to require the use of an internal mandrel.

The OneSteel results plotted on the chart below demonstrate how the increased side support to the pipe by the Elliptical and Cathedral profile, enabled the OneSteel pipes to be bent successfully without an internal mandrel.

Notes:

1. Centre line radius can vary between former manufacturers.

2. Results apply only to OneSteel products, and only for the sizes and grades listed above.

3. Roll type bender recommended for DuraGal DN50 Extra-Light

Elliptical: Pipe sits close to, but not on, the bottom of the former. Good side support, sides of the former are above the centreline of the pipe.

Cathedral: Pipe sits on the entry to the former and will move to the bottom when bending starts. This action gives a small amount of squeeze that supports the lighter gauge pipe.

Ram Bending Hints - Some wrinkling of the inside of the bend can be expected on CHS (DN32 and DN50 are most prone to wrinkling).

- If the bend collapses (i.e. the centre of the bend lifts out of the former) during bending, move the support rollers in. For the support roller centres used during development and testing of the formers refer to the following table.

DEFINITIONS Black

Hot Dip Galvanized

A smooth, even coat of clear temporary rust preventative (TRP) is applied to the external surface.

A process in which mechanically and/or chemically cleaned steel is submerged in molten zinc. This results in a zinc coating which forms a strong metallurgical bond with steel (without further processing) unlike electroplating, zinc spraying, painting with zinc rich coatings, mechanical plating or metallising. See “Surface Finish” in this Product Information section for more details.

Blue Painted A smooth, even coat of blue general purpose paint is applied to act as a temporary rust prevention. See “Surface Finish” for RHS/SHS in this Product Information section for more details.

CHS

Mill (Cut) Ends

Circular hollow section. Also called pipe or tube. These names originated from the designations “pressure pipe” and “mechanical tube”.

DuraGal® , Galtube Plus® and Tubeline® products have friction sawn or shear cut ends. There may be some rag. The cutting tooling is changed regularly to minimise the rag.

Clear Coated

Ultrapipe® is generally supplied with Bevelled ends.

See “Black”

Nominal Size (DN)

Colour Coding (Tube ends)

A pressure pipe term, but commonly used by distributors to describe all circular hollow sections in sizes up to 165.1 OD. Historically it was used to describe pressure pipes with similar flow rates at a given pressure or head.

Unless otherwise indicated in “Surface FInish” in this Product Information section, the ends are colour coded as per AS/NZS 4496: Recommended practice for the colour coding of steel products.

Standards Australia has adopted DN (from French diametre nominel) as the nominal size designator for pressure pipe. NB, nominal bore (nominal inside diameter) was the term used in Australia up till the late 1980’s.

DuraGal® A high strength hollow section or angle, channel or flat that is in-line hot dip galvanized with a minimum average zinc coating mass of 100 g/m2 per coated side. Only the outside of the hollow sections is galvanized. See “Surface Finish” in this Product Information section for more details.

DuraGal® Internally Painted A DuraGal hollow section that has been internally painted over a prepared metal surface. See “Surface Finish” in Product Information at the front of this section for more details.

DuraGal® Plus (Angles for Masonry Lintels) A high strength angle that is in-line hot dip galvanized with a minimum average zinc coating mass of 300 g/m2 per coated side. See “Surface Finish” in this Product Information section for more details.

Refer also to the OneSteel publication: DuraGal® Plus for Masonry Lintels.

End Colour Coding To assist in easy recognition of the thickness of SHS, RHS, angles, channels & flats and the Quality of CHS, a colour is applied to the cut ends of all Australian made sections, except Galtube Plus, UltraPipe and sections ordered with NOP (No Oil or Paint) surface finish.

The end colour codes are set out in AS/NZS 4496: 1997 Recommended practice for the colour coding of steel products.

Galtube Plus® A ductile hollow section that is in-line hot dip galvanized with a minimum average zinc coating mass of 125 g/m2 per coated side. This product is generally internally painted with an Zinc Phosphate paint over a prepared metal surface. This product has the same strength as AS 1163 C350L0 hollow section but with the ductility to allow the product to be further processed without splitting or tearing, ie. crush bending or flat trapping. See “Surface Finish” in this Product Information section for more details.

HDG See “Hot Dip Galvanized”.

Both the external and internal surface of the hollow section is supplied in the “As Rolled” condition without protective coatings. Some dirt, usually loose mill scale, and mill lubricant contamination is unavoidable.

The ends are not colour coded.

Oiled This is not a mill option for the OneSteel products within this publication.

Profiles DuraGal profiles are in-line hot dip galvanized angles, channels and flats. See “Surface Finish” in the Product Information at the front of this section for more details.

Quality An indication of the wall thickness of CHS. Historically used to describe pressure pipe where each “Quality” designated pipes with similar pressure capacity. Changes in steel making and pipe manufacturing methods have overtaken this link.

Five Qualities are commonly manufactured in Australia; Extra-Light, Light, Medium, Heavy and Extra-Heavy.

Not all Qualities are available in all sizes.

Generally the thickness of the pipe increases, as size increases, for a particular Quality.

Red Painted A smooth, even coat of red general purpose paint is applied to act as a temporary rust prevention. See “Surface Finish” for CHS in the Product Information at the front of this section for more details.

EFFECTIVE SECTION PROPERTIES

FULL SECTION PROPERTIES

1. This table is calculated in accordance with AS/NZS 4600 using a design yield stress fy = 350MPa and design tensile strength fu = 380MPa. 2. Effective section properties are calculated in accordance with AS/NZS 4600.

3. All columns of the table (except for “Nominal Mass per m” and External Surface Area”) are calculated using design thicknesses of 1.45mm and 2.4mm rather than the respective thicknesses t of 1.6mm and 2.5mm. This is to comply with clause 1.5.1.6 of AS/NZS 4600.

4. For Square and Rectangular Hollow Sections the outside corner radius r used in calculating the section properties is equal to 2 t for sections with thickness t £ 3.0mm and 2.5t for sections with t > 3.0mm.

1. This table is calculated in accordance with AS 4100 using design yield stress fy = 450 MPa and design tensile strength fu = 500 MPa as per AS 4100 table 2.1 for AS 1163 grade C450L0.

2. Grade C450L0 is cold formed and therefore is allocated the CF residual stresses classification in AS 4100.

3. C = Compact Section; N = Non-compact Section; S = Slender Section; as defined in AS 4100.

4. For SHS and RHS the outside corner radius r used in calculating the section properties is equal to 2t for sections with thickness t £ 3.0mm and 2.5t for sections with t > 3.0mm.

5. DuraGal Dual Grade C350L0/C450L0 hollow sections have a minimum yield stress of 450MPa (fy = 450MPa), a minimum tensile strength of 500MPa (fu = 500MPa) and a minimum elongation equal to 16%, ie. the strength of AS 1163 grade C450L0 and the elongation of AS 1163 grade C350L0.
