A105N Carbon Steel Socket Weld Flange

What is a WN Flange?and what about its specification

900LB slip on flange can slip on the pipes and welded with the pipes.Stainless steel flanges are popular because of the an-ti corrosive function.Stainless steel flange can used over 50 years.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

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.

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.

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).

Standards and application Referred for WN flange and application

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

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.

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.

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.

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.

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.

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.

flange type: 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)

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 bore of the slip on will give ample amount of space for the matching pipe. This allows for enough working space for the welder and fabricator to make the connection.Slip-On flanges are commonly lower in price than weld-neck flange.

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.
The Alloy Steel A182 Threaded Elbow material grade contains ASTM A182 F11 / 12 / 5 / 9 / 91 / 92 / 22.

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.

A flange can be defined as a method that helps in connecting pipes, valves, etc., to form a full piping system. There are six flange classes ranging from #150 to #2500. Governed by B 16.5 standards, the ASME B16. 5 Class 300 Flange provides a pressure capacity of 300Lb.

The difference between ASME/ANSI and API

WN flanges is the most popular type of flanges.ASTM A182 F304 is a American standard grade of stainless steel.The other popular grade is A182 F316.ASME B16.5 forged flanges inculding WN flange,SO flange,SW flange,THD flange,LAPJ flange,BL flange.All types of flanges have pressures:150#,300#,600#,900#,1500#,2500#.

Material Grade: ASTM A182 F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.

ASME B 16.5 2 inch socket weld (SW) flanges are used for small size and high pressure pipe systems.Stainless steel flanges are more expensive than carbon steel flanges because of the better functions.The pressures could be chosen:CL150,CL300,CL600,CL900,CL1500,CL2500.

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.

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.

ASME B16. 5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.
