ASME B16.5 Flange Class 150 WN Flange

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.

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

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

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.

150 LB blind flange is a flange similar to plug.BL flanges are used to close the pipe system.ASTM A105 forged flange is carbon steel flange in American Matel Standard.

ASME B16.5 forged flanges are high pressure flansges inculding pressures 150LB,300LB,600LB,900LB,1500LB,2500LB.SS316 CL300 flanges is a kind of stainless steel CL300 flanges.Other popular grades of stainless steel are SS316L,SS304/304L.

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.

Stainless steel socket flanges are installed during pipeline construction and connected to another pipeline through bolts to achieve a tight connection of the pipeline.

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.

ASTM A182 F316 Threaded Flange is a flange manufactured according to A182 standard, and its connection method is threaded connection. It is a commonly used connector in pipeline systems, used to connect pipelines, valves, pumps and other equipment, so that fluids can be smoothly transmitted within the system.

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.

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.

Slip-On flanges are commonly lower in price than weld-neck flange.However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation.

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

It is generally used in non-corrosive, non-critical, moderate pressure services. Slip on flanges of Class 150 and Class 300 are most commonly seen in utility engineering. Similar to welding neck flange, the slip on flange conforming to ASME B16.5 may generally be furnished with three facing types: raised face (RF), flat face/ full face (FF), or ring type joint (RTJ).

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

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.

The ASME B16.5 Weld Neck Flange is a welding-type flange cast or forged integrally with the tapered neck. It is then buttwelded to the piping system. The ASTM A182 SS WNRF Flange is made of austenitic steel consisting of 18% chromium and 8% nickel, and it is this composition that makes the flange strong and highly resistive to corrosion. 

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.

The main structural feature of the stainless steel lap joint flange is the loose connection. It consists of a flange body, a flange nipple and connecting bolts. The flange body and the flange nipple are loose fitting, and this structure allows the pipeline to expand and contract freely within a certain range.

Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. 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.

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.

The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used. (A nozzle is typically a pipe coming out of a vessel and is usually flanged so it can be connected to valves or piping). 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.

SW flange can be used in many applications in piping systems.SW Flanges are forged flanges.Socket weld flange has many classes:150LB, 300LB, 600LB, 900LB, 1500LB, 2500LB.Stainless steel flanges have better functions than other flanges which made from carbon steel or alloy steel.

A182 F304 slip on flange include flanges, bolt holes and sealing surfaces. The flange is a flat ring structure with an outer diameter larger than the outer diameter of the pipe connected to it. The bolt holes are evenly distributed on the flange and are used to install bolts to connect two flanges.
