ASME B16.5 600LB Forged Steel Flange Packing

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.

A105 FF slip on flange is a commonly used pipeline connection element, mainly made of carbon steel, and connected to pipelines or other flanges by flat welding. The structure of the slip on flange is relatively simple.

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).

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.

300LB THD flanges are one types of flanges.Other types of flanges are WN,SO,SW,LAPJ,BL.ASTM A182 F316 flanges are popular in many corrosive environments because of the excllent corrosion resistance.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

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.

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.

Welding neck flange benefits

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.

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.

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#.

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.

Usage of a weld neck flange

Stainless steel pipe fittings including Tee,Cross, Elbow, Reducer, Coupling, Nipple, Plug & Cap,Union.They can be connected with pipes by welding, socket and thread.

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.

Class 300 LAPJ flanges are used with lap joint stub end.The pressures for ASME B16.5 forged flanges including 150LB,300LB,600LB,900LB,1500LB12500LB.

CL 600 slip on flanges are commonly used type of flanges.ASTM A182 F316L is a popular grade for stainless steel.Stainless steel flanges are popular because of the an-ti corrosive function.Stainless steel flanges can used over 50 years.

Classification of weld neck flange

What is a Weld Neck Flange and its 2 different shapes

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.

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.

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.

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.

Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe.

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.
