SW Flange

Socket weld flange simplified as SW flange, it has a recessed area (like a shoulder) in the flange bore, this shoulder serves as a guide to set the depth of the pipe that inserted to the flange. Socket welding flange initially designed for high pressure small diameters piping system.

Advantages

Socket weld flange could replace threaded flange, to minimize the risky of leakage.
No need to beveling before welding.
Welding work outside of the pipe, will not penetrate the pipe bore
It is recommended for applications where internal welding operations are particularly difficult. This sock welded construction eliminates internal pockets while avoiding warpage of welding heat and damage to the flange face caused by weld spatter. It has the same internal pressure as the sliding on the flange, and has a better fatigue life.

Features of Socket Weld Flange

01.

Pressure and temperature:

This flange can be used in high pressure applications, that is why it is used in industries such as oil, gas and petrochemical.

02.

Tight connection:

This flange establishes a tight and leak-proof connection with the pipe or other equipment with the help of welding.

03.

Different sizes:

Socket Weld Flanges are available in different classes and sizes according to the standards. For example, for this flange, there are sizes from 1/2 inch to 24 inches in the ASME B16.5 standard.

04.

Class:

In the ASME B16.5 standard, the classes for this flange includes: 150, 300, 400, 600, 900, 1500 and 2500.

Socket Welded Flange Face Types

RF Type:

An RF socket weld flange features a small raised portion around the flange bore, serving as a seat for the gasket, promoting effective sealing.

RTJ Type:

The RTJ type entails a groove on the raised face surface, allowing for the placement of a gasket ring to enhance sealing performance.

Socket Weld Flange vs. Slip-On Flange:

A socket weld flange closely resembles a slip-on flange, but it distinguishes itself by having a shoulder within the inner bore.
