Flanges & Fittings Connections+Tightness The vacuum system requires connections with either pumping systems or diverse kinds of peripheral accessories, including valves, vacuum gauges, etc. Whilst all these connections must have pressure vacuum integrity, and also have to be modular, allowing required maintenance & flexibility. The vacuum applications involve flanges as well as fittings with requirements that are strict, including materials, dimensions, conductance, tightness, etc. On the other hand, vacuum flange manufacturers also strictly follow.
Providing A Wide Range Of Flanges & Fittings At Saini Flanges Pvt. Limited (ISO 9001:2008 Co.) we are one of the offshore & leading vacuum & precision machined components manufacturers, and we have been providing a wide range of flanges & fittings for over two decades. When it comes to vacuum flanges, offering an extensive range of flanges such as KF/QF, CF, ISO & ASA flanges of stainless steel that work in advance temperature & corrosive conditions. Vacuum flanges are used in HV/UHV applications, including gas, vacuum & steam chambers for both equipment manufacturers & end users. For each standard, we offer normal & minimal diameters that usually use. On the other hand, offering a large number of accessories for each standard, including tees, elbows, 4 way crosses, reducers, flexible couplings, etc. When it comes to working pressure, the two terms are tightness & conductance needed. The fittings will be manufactured with one of the following standards:
ISOKF The used materials are such as stainless steel, aluminum & macrovac. ISOK Used Material is stainless steel. CF Used Material is stainless steel.

ISOKF Flange & Fittings Reliable: ISOKF Flange & Fittings allow tight connection & quick release from the range of 1050 mm nominal diameters. With two flanges coupled together through centrering with Oring & a clamp. This sort of connection provides numerous advantages, including: • • • •
Quick & Easiest Mounting Unlimited Orientations Easy Interchangeability Assembly without any tools
Stainless Steel Series Components: This is used in corrosive, high vacuum or hightemperature applications, stainless steel flanges & fittings, and according to the material like steel & a large number of highperformance, including: • Used with FPM Oring • Used with NBR Oring • Use with metal seal
Connections Between Different Diameters ISOKF Flanges These is a range of nominal diameter of flanges as in 10, 20, 32 mm, and the same external diameters as in 16, 25, 40 mm, therefore, the connections 10/16, 20/25, 32/40 connections are very easy, using an adapter ring with the Oring. All these connections are also easy with a metallic seal since they are centred on the flange outside diameters. When we talk about other different diameters, then the conventional reducer must be used.

ISOK Flanges & Fittings
High Conductance Pressure: Providing ISOK flanges & fittings range includes 6 diameters from DN 63 to DN 250. It includes: • • • •
Easy Assembly 360 degrees orientability High Conductance Baked to temperature 80 to 150 degrees Celsius
Rotatable Flange Connection: It includes two ISOK flanges coupled together with two rotatable flanges with a centring ring with Oring, retaining ring and a bolts set. This sort of connection allows an easiest angular orientation. In simple terms, ISOK is made up of stainless steel, and it ranges the components that include elbows, tees, weld flanges, 4way crosses, nipples, etc. All these accessories are available in two forms such as ISO entre axe & metric tubing, on the other hand, with the US Standard entreaxe & tubing.
Double Claw Clamp Connections: The double claw clamp connection includes two of the some nominal diameter flanges and onecentring ring with Oring. According to the nominal diameter, there is 4 to 6 double claw clamps.

CF Flanges & Fittings At Saini Flanges Pvt. Ltd, we as vacuum flange manufacturers use ultra high vacuum component range is based on the CF “Conflat” standard that uses a copper gasket compressed between the knife edges of CF flanges. Because of the principle, the CF coupling ensures perfect tightness. Offering a wide range of Flanges & Fittings We offer CF Flanges in both versions such as rotatable & nonrotatable from 16 to 250 mm, which if often used in ultrahigh vacuum applications. Easier Mounting Providing tappedhole flanges in order to avoid a number of nuts & washers. The tappedhole flanges are available with metric or US standard tapping. In addition, in order to simplify the customer's purchase, offering nut & bolt sets for each kind of coupling. Range of Baking Temperature It includes stainless flanges & copper steal, a ultrahigh vacuum CF coupling can be baked to 450 degrees Celsius.

InterStandard Adapters There are some peripheral accessories that are used in vacuum industries and are not available in all standards. Because of this phenomenon, at Saini Flanges Private Limited, we are offering special adapters that vary from one standard to another. ISOKF to ISOK Adapters All these stainless accessories allow highperformance coupling. The baked temperature & pressure range depends upon the steel used for one of the two couplings. When it comes to CF coupling, then it has highperformances so that it is the ISOK coupling that limits these adapters. According to the material of steel, the performances will be as following: • •
Use with an FPM Seal Baked temperature 150 degrees Celsius Use with an NBR Seal Baked temperature 80 degrees Celsius
