ASTM A182 Stainless Steel Flange
We are the manufacturer of steel flange and pipe fittings. Slip on flange, also called SO flange, is the common type of steel flange. The specification of ASTM A182 is the standard of forged fittings, stainless steel, rolled alloy, forged alloy, pipe flanges and pipe fittings.
These Stainless Steel Flange and Pipe Fittings are best known for their heat resistance, creep strength and tensile strength. Machined and fabricated to meet your diverse piping requirements, these pipes fittings exhibit excellent corrosion resistance in a wide range of atmospheric environments.
The specification of ASTM A182 is the standard of forged fittings, stainless steel, rolled alloy, forged alloy, pipe flanges and pipe fittings as well as high-temperature service. Later then forgings and hot working, it would be cooled down to a certain temperature before heat treatment.
The common material grade of stainless steel ASTM A182 contains F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.
ASME B16.5 Flange
ASME B16.5 is the standard of flange, and it contains Weld Neck Flange ( WN),Slip-on Flange (SO), Threaded Flange (THD),Socket Weld Flange (SW),Blind Flange (BL),Lap Joint Flange (LAPJ),Plate flange (PL). The size range of forged steel flange is 1/2″ – 48″/ DN15 – DN1200. There are seven flange classes ranging: #150, #300,#400, #600, #900, #1500 #2500 which means the pressure it can bear.
ASME B16. 5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.

Slip on flange can be made by forging, steel cutting, casting and etc. Among these manufacturing types, the forging type gains the best quality and also the most common use.
Slip on flange, also called SO flange. It’s a kind of flange slides over the pipe with internal design is slightly larger than the pipe. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, the SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange. It is used to insert the pipe into the inner hole of the flange.
Slip On Flange
A flange can be defined as a method that helps in connecting pipes, valves, etc., to form a full piping system. There are seven flange classes ranging: #150, #300,#400, #600, #900, #1500 #2500. Governed by B 16.5 standards, the ASME B16. 5 Class 900 Flange provides a pressure capacity of 600Lb, Class 1500 Flange provides a pressure capacity of 1500Lb
