Refer to the sections below for a description and the availability of the various surface finishes within the Tubeline® range. Hot Dipped Galvanised (HDG) – Availability: 26.9 to 165.1 mm. A hot dip galvanized coating is applied over prepared metal surfaces to both the external and internal surfaces to produce a fully bonded coating with a minimum average coating mass of 300g/m2 in accordance with Coating Class HDG300 of AS/NZS 4792: Hot-dip galvanized (zinc) coatings on ferrous hollow sections, applied by a continuous or specialized process. 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 to 12 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. The ends are not colour coded. NB: From mill rollings only, minimum order quantities may apply. Oiled – This is not a mill option for the OneSteel products within this publication.

Bending

DuraGal

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.

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: Process

Painting 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 zinc rich primer or epoxy mastic applied to a suitably prepared surface will 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 environments the weld areas should be adequately protected according to the coating manufacturers recommendations prior to topcoating. Some environments cause especially rapid corrosion. They include industrial areas, marine environments, polluted cities, some farming activities, animal husbandry and other corrosive environments. 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.

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 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.

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

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. 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. 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 load-bearing, or lightly loaded, unless the deformed section is stiffened.

Product Information

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. 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 (60.3 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)

- 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. Size (DN)

Rollers Centres (mm)

380

450

520

590

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 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.

Try a different bending technique.

The Right Former

Try a heavier gauge pipe.

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.

Effect of Bending Former 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).

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.

Using the Elliptical and Cathedral formers tabled in this section, a series of ram bending trials were performed on OneSteel’s Tubeline® and 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

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).

Nominal Size (DN) 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.

See “Surface Finish” in this Product Information section for more details.

The OneSteel range of HDG, Black and Painted CHS & RHS hollow sections. Tubeline® hollow sections comply with AS 1163 Grades C250L0, C350L0 or C450L0. Refer to the sectional property tables for details of sizes and shapes that can be manufactured within the different grade designations of AS 1163.

UltraPipe®

See “Hot Dip Galvanized”.

For Structural applications, UltraPipe® is tested to and complies with the requirements of AS 1163 Grade C350L0 and is included within the relevant tables for Large Structural CHS (168.3 to 457.0mm) hollow sections AS 1163 Grade C350L0.

Hot Dip Galvanized

Varnish

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)

This is usually only found on imported products.

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. Grade C450L0 is cold formed and therefore is allocated the CF residual stresses classification in AS 4100. C = Compact Section; N = Non-compact Section; S = Slender Section; as defined in AS 4100. 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. 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.

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. Grade C450L0 is cold formed and therefore is allocated the CF residual stresses classification in AS 4100. C = Compact Section; N = Non-compact Section; S = Slender Section; as defined in AS 4100. 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. DuraGal® DualGrade® 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. 6. Sizes shown in Italics: These sizes may not be stocked in all states or minimum order quantities may apply.

In this table, the properties of these products are calculated in accordance with AS 4100 using design yield stress fy = 350 MPa and design tensile strength fu = 380. Type 2 products are not made strictly in accordance with AS 1163. Care should be used when designing structures using these products. Grade C350L0 is cold formed and therefore is allocated the CF residual stresses classification in AS 4100. C = Compact Section; N = Non-compact Section; S = Slender Section; as defined in AS 4100. For Square and Rectangular Hollow Sections 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.

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. Grade C450L0 is cold formed and therefore is allocated the CF residual stresses classification in AS 4100. C = Compact Section; N = Non-compact Section; S = Slender Section; as defined in AS 4100. 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. DuraGal® DualGrade® 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. 6.

With the exception of J, properties are calculated assuming a simplified shape where the bends are eliminated and the section is represented by straight mid-lines in accordance with Clause 2.1.2.1 of AS/NZS 4600. bx is zero for equal angles. Iw is equal to zero for angles. The shear centre is assumed to be located at the intersection of the centre lines of the angle legs. Sizes shown in Italics may not be stocked in all states or minimum order quantities may apply. # are also available as DuraGal® Plus (Lintels).
