Elbow Pipe Fittings| Thread Elbow Fittings

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

There are 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). We also supply alloy steel flanges and stainless steel flanges .

Welding neck flange benefits

Threaded nipple is a short piece length of pipe or tube. Its size is specified according to the length of this section of pipe and the diameter. It can be with threaded or flat ends. And both ends can be the same or different.
There are two shape : threaded one end (TOE) and threaded both end ( TBE).

What is a WN Flange?and what about its specification

These Stainless Steel A182 Threaded Union 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.

Stainless steel flange, also called SS flange, it means the material of flange is stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500.

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.

600LB SW flanges can socket with the flanges and then welded with the pipes.Large diameter flanges can be series A and series B.ASME B 16.47 A & B are standard for large diameter flanges.

Usage of a weld neck flange

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 flange can socket with the end of pipe,and welding on the pipe.Stainless steel flanges are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

An assembly with limited space may be an instance in which a socket weld is selected, provided the pressure class is comparatively low and the fluid is not corrosive or for extremely high temperature service.

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

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.

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.

What is a weld neck flange and what about its dimensions?

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

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.

Class 150 WN flange is the lowest pressure flange in all the flanges,langes also have many pressures:CL300, CL600, CL900, CL1500, CL2500.ASTM A105 is the matal standard for forged flanges and fittings.

300 LB BL flanges are used to close the pipe system,it is similar to plugs and caps.Stainless steel 304 flanges are the most used stainless steel flanges as SS304 have excllent functions and reasonable price.

What is a Socket Weld Flange,what abut its specification and advantages

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.

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.

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

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.

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.

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
