300LB SO Flanges Stainless Steel Forged Flanges

The descipton ,specification ,and advantages of a weld neck flange.

ASTM A105 Forged Fittings 300# WN Flange
Size Range: 1/2″ – 48″/ DN15 – DN1200
Rressure rating: Class 150, 300, 600, 900, 1500, 2500lb

300LB Stainless Steel Flange is always be chosen because of the excellent anti-corrosive function,SS316 is one of commonly used grade for stainless steel.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

Reducing pipe (reducing nipple) is a pipe fitting used for straight-line connection of two pipes with different sizes to realize pipe diameter reduction. There are concentric reducing joints and eccentric reducing joints

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.

What is a weld neck flange and its specification?

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.

These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.

ASTM A182 F304 spectacle blind is more often used than carbon steel spectacle blind as its great anti-corrosive function.ASME B16.48 is the standard of spectacle blinds.The two components have different functions in the piping system.

What is a WN Flange?and what about its specification

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

There are varies advantages of stainless steel flange:
Resistant to corrosion and staining
Low maintenance
Bright familiar luster
Steel Strength

Many times a nozzle will be blanked off with a blind flange for pressure tests in a plant, or simply because the customer does not need all the nozzles that were supplied on the tank.

Class 600 WN flange is a high pressure flange.Flanges have many pressures:CL300, CL600, CL900, CL1500, CL2500.ASME B16.5 is the American Standard for flanges.Flanges have five face types:RF RTJ FF MF TG.

This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.

A WN / weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange.

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.

Socket Weld Half Couplings is utilised in various applications in order to provide a torque free sealing and a leak free connection. Socket weld coupling is a very short section of pipes with socket bore at both ends or one end, but both can afford high pressure of 3000#, 6000#, 9000#. The Socket Weld Half Coupling are often directly welded to the run pipe, to form a branch connection.

There are various material grade for ASTM A182 stainless steel flange: F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.

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.

150LB threaded flanges are one types of flanges.Other types of flanges are WN,SO,SW,LAPJ,BL.Stainless steel 316L flanges are popular in many corrosive environments because of the excllent corrosion resistance.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

The common material grade of stainless steel ASTM A182 contains F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.

Materials of WN Flanges

High pressure flange carbon steel material: ASTM A105 / A105N, ASTM A350 LF2/LF3, ASTM A694 F42 / 46 / 56 / 60 / 65, P235GH, P265GH, P280GH, P355GH

The slip-on flange is a simple and excellent alternative to a weld neck as it does not have a weld bevel, and therefore allows the pipe to be adjusted in length relative to its position of the flange. The bore of the slip on will give ample amount of space for the matching pipe.

DN150 SW flange is a 6in flange used to socketed with the pipes and then welding on pipes.CL150 forged flange is the lowest pressure flange.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.
