What is Socket Weld Flange

Socket weld flange refers to a flange that is inserted into the flange ring step at the end of the pipe and welded at the end and outside of the pipe. Socket weld flanges are typically useful on smaller sizes of high-pressure pipes. These pipe flanges are attached by inserting the pipe into the socket end and applying a fillet weld around the top. It allows for a smooth bore and better flow of the gas or fluid inside the pipe.

Socket weld flange has two types of with a neck and without a neck. The neck flange has good rigidity, small welding deformation, and good sealing performance, and can be used in situations with pressures ranging from 1.0 to 10.0MPa. Due to their lower integrity and unsuitability for use at higher pressures, socket weld flanges almost always have flat or raised faces.

The standard of forged flange following ASME B16.5. According to this standard: socket flange pressure rating grades including Class150, Class300, Class400, Class600, Class900, Class1500, and Class2500. Let’s have a review of CL150 Socket Flange.

Socket Flange Standard

For inspect pressure stability ratings, materials, dimensions, tolerances, markings, experiments, and identification methods of forged flanges what based on ASME B16.5 standard.

ASME B16.5 standard includes:

Size specifications:  NPS 1/2 IN - NPS 24 IN;

Pressure rating grades: Class150, Class300, Class400, Class600, Class1500.

This standard is limited to:

(1) Flanges and flange fittings made of casting or forging;

(2) Flange covers made of casting, forging or sheet metal, and some reducing flanges.

Socket Welded Flange Face Types

RF type : It has a small portion surrounding the flange bore that protrudes from the face. Gasket seat will be placed in this raised area. 

RTJ type: On the raised face surface there has a groove is RTJ type which you can place a gasket ring to get better sealing performances.

Socket Flange Material Reference

Carbon Steel:  ASTM A105, ASTM A350 LF2/3

Alloy Steel:  ASTM A182 F5, F9, F11, F22, F91
Stainless Steel:  ASTM A182 F304L, F316L, F321, F904L, F51, F53

CL150 Socket Flange Advantages

No need to beveling before welding.

It has the same internal pressure as the sliding on the flange.

Welding work outside of the pipe, will not penetrate the pipe bore.

Socket weld flange could replace threaded flange, to minimize the risky of leakage.

This sock welded construction eliminates internal pockets while avoiding flexion of welding heat and damage to the flange face caused by weld spatter.
