ASTM 182 Stainless Steel Flange Weld Neck(WN) Flange ASME B16.5

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.

ASME B16.5 SW flange is belong to American Standard for forged flanges,this kind of flange are been used all over the word.Forged flanges are high pressure flanges,the commonly used classes are CL 300,CL 600 for forged flanges.Stainless steel flanges always more expensive than other flanges because of the stainless steel has better functions.

Slip on flange also named as SO flange. SO flanges slip over pipes and are designed to bit slightly bigger on the inside than the pipe. They connect to the pipe through a fillet weld at the flange top and bottom.

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.

What is a WN Flange?and what about its specification

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

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.

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.

TOE means threaded at one end when translated. Thus, we can say that a nipple TOE is a nipple that has one threaded end.
In this case, we have the acronym TBE for “threaded both ends” which means threaded at both ends. In other words, this is the most typical type of nipple as described above for connecting two parts or fittings with female threading.

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.

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.

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.

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.

What is a Spectacle Flange and what about its specification and advantages.

ASME B16. 5 pipe flanges: 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 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.

150LB slip on flange is the lowest pressure flange in all pressure flanges.ASME B16.5 forged flange is manufacted according to American Standard.Pressures for flanges have 150LB,300LB,600LB,900LB,1500LB,2500LB.

The difference between ASME/ANSI and API

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.

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.

Stainless steel 316L LAPJ flange has great anti-corrosive function,it always used with lap joint stub end of same material.ASME B 16.5 forged flange have soem pressures:CL150,CL300,CL600,CL900,CL1500,CL2500.You could find the comparison between LAPJ flanges,SO flanges and WN flanges below.

It is used to insert the pipe into the inner hole of flange, as the flange inner diameter is little bigger than the pipe’s outer diameter, pipe and flange could be connected by lap welding at the top and bottom of the flange. 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.

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 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.

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.
