ASTM A182 Weld Neck Flange

Hastelloy C22 slip on flange is a nickel-chromium-molybdenum-tungsten alloy flange with excellent corrosion resistance. It can perform well in various harsh corrosive environments, such as environments containing strong corrosive media such as chloride ions and sulfate ions.

Blind flanges are used to seal the end of piping systems or pressure vessel openings.

The specification of ASTM A182 Forged Pipe Fittings includes forged fittings, stainless steel, rolled alloy, forged alloy, pipe flanges as well as high-temperature service. Later then forgings and hot working, it would be cooled down to a certain temperature before heat treatment.

Face Type of a WELD NECK flange

Classification of weld neck flange

CL 600 slip on flanges are commonly used type of flanges.ASTM A182 F316L is a popular grade for stainless steel.Stainless steel flanges are popular because of the an-ti corrosive function.Stainless steel flanges can used over 50 years.

WN flange is a commonly used type of flanges,ASMT A150 forged flange is carbon steel flange according to American Standard.Flanges have many types:WN,SO,SW,THD,LAPJ,BL.

Equal tee is one type of pipe fittings, also called straight tee which means the branch diameter is same with the main pipe (Run pipe) diameter.

A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has numerous holes drilled into it that enables the flanged to be attached to a bolted flange.

The equal cross is one kind of the pipe cross,  the equal cross means all the 4 ends of the cross are in same diameter.
The reducing cross also is called unequal pipe cross , it is the pipe cross which the four branch ends are not in the same diameters.

Stainless steel spectacle blind has better anti-corrosive function than other material of spectacle blinds.ASME B 16.48 is a commonly used standard for spectacle blindThe joint face can be RF (Raised Face), FF (Flat Face), RTJ (Ring Joint),it is depend on the type of flanges.

Alloy Steel: ASTM A182 F11 / 12 / 5 / 9 / 91 / 92
Stainless Steel: ASTM A182 F304/304L/304H, 316/316L, 321, 310S, 317,347,904L, 1.4404, 1.4437.

Flange provides a long tapered hub for welding to pipes , it is used in high pressure systems and suitable for both cold and hot temperatures.

600LB Silp On (SO) Flange can slip on the pipes and welding with the pipes.Stainless steel flange are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

Flange connection is to fix two pipes, pipe fittings or equipment on a flange first, and then Flange pads are added between the flange plates and fastened together with bolts to complete the connection

Socket Weld Flange contain a shoulder on the flange inside that acts as a guide to set the depth at which the pipe is welded to the flange.

Large diameter flat welding flange has less high-pressure suitability compared to its weld neck counterpart. The basic ring style is suitable for the occasion of low pressure. The butt weld category of the flange is known as a weld neck flange. It suits the occasion of high temperature and pressure as defined in the ASME B16.47 code.

1500 LB SO flanges are belong to high pressure flanges.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.Flange dimension has a very large range to meet different demands.

Stainless steel lap joint flange is always used with lap joint stub end (a kind of butt welded fitting).A182 F304 forged flanges have great anti-corrosive function,flanges in this material have longer using years than other materials.

The smooth transition between the flange and the hub combined with the strength of the butt weld joint, allows the flange to be used in extreme conditions of cyclic loading, bending and temperature fluctuations.

18in CL600 WN flange is belong to large dimension flanges.ASME B16.5 is standard for forged flanges.Forged flanges have important functions in high pressure enverionments.

The connection method of A182 F11 socket flange is to insert the pipe into the socket of the flange, and then seal it with welding or use a sealing gasket. This connection method is relatively strong and can adapt to the thermal expansion and contraction of the pipe to a certain extent.

A105 WN flange is a carbon steel flange according to ASME B16.5.STD is represents the thickness of the flange.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.Flanges have five face types:RF RTJ FF MF TG.

Stainless steel slip on flanges are popular type of flanges because of the great material and flexible applications.Pressures of flanges:CL150,CL300,CL600,CL900,CL1500,CL2500.ASTM A182 F316L and ASTM A182 F304 are both popular grades of stainless steel.

Socket weld (SW) flange is a type of forged flanges,these flanges can socket and wedled with pipes,you could find the flanges specifications in the content below.Stainless steel flanges are popular because the stainless steel has great corrosion resistance so that these flanges can used in some corrosive environments.

orged steel flange is a disc-shaped piece of equipment used to connect a pipe to fittings or valve or other component to form a pipework system. Usually flange has been attached to pipe or tube end to, and then a gasket is inserted in the middle to form a seal. Finally they are joined together with bolts and nuts.

Standards and application Referred for WN flange and application

A182 F304 forged flanges are stainless steeel flanges,ASME B16.5 SW flanges are socket weld flanges following American Standard specifications.

One end of the ASTM A182 socket weld flange is a socket structure, and the pipe can be inserted into the socket for welding connection. This connection method has a certain degree of flexibility and can absorb a small amount of displacement and vibration of the pipe. At the same time, it is relatively easy to install and has good sealing performance.
