SAE Socket Weld Flanges and Counterflanges

SAE Socket Weld Flanges are one of the main types of SAE wled flanges, which are designed and manufactured according to standard ISO 6162-1/ ISO 6162-2. Products are conform to standard SAE J518 as well.

Main styles:

SAE socket weld flanges
Flat style SAE socket weld flanges
SAE 90° flanges / SAE socket weld elbow flanges

Standard:

ISO 6162-1: for 3000 psi standard pressure series (light duty), known as code 61 flanges as well
ISO 6162-2: for 6000 psi high pressure series (heavy duty), known as code 62 flanges as well

Materials of Socket welding flanges:

Carbon steel: S355J0, C45, C20 or equivalent, other steel grades on request
Stainless steel: AISI 304 (EN/DIN 1.4301), AISI 316 (EN/DIN 1.4401), AISI 316L (EN/DIN 1.4404), AISI316Ti(EN/DIN 1.4571), and duplex stainless steel grades, other steel grades on request. Stainless steel SAE Flanges are needed when connecting stainless steel hydraulic tubing.

Surface conditions:

Carbon steel Socket weld flanges can be supplied with below surface conditions:

Zinc coated (white): thickness of Zinc plate is more than 8 µm, thicker zinc plate is available on requests.
Yellow Galvanized zinc
Phosphated (black)
Nickle plated
Blank + oiled
Untreated oxidation

Working pressure:

The working pressure of standard pressure series SAE socket welding flanges is between 35 bar to 350 bar, depends on the sizes and the blots used.
For 6000 psi high pressure series socket weld flanges, the working temperature can be up to more than 400 bar.

Size Range:

Younglee produce and supply a wide range of sizes of SAE socket weld flanges as in below table.
