Main Classification And Manufacturing Standard Of Three – Pass

The socket three links, also called forged high voltage three links, belong to high pressure fittings, and are suitable for high pressure pipes, specifications DN15-100. Material: 20#, 12Cr1MoV, 201, 304, 316. Pressure: 3000LB, 6000LB, 9000LB.

Three – way classification of socket

There are many kinds of structural forms. According to the manufacturing process, it can be divided into (cold and hot) extruding three – way, forged three – pass and welding three – way. The welding three – pass can be divided into thick wall strengthening welding three, single bar reinforcement welding three and disc type strengthening welding three through three. According to the external shape of the three links, it can be divided into oblique three links, orthogonal three links and Y shaped three links.

Three – pass manufacturing standard

The three – way domestic standard is three through, whether it is the industry standard (such as the power department GD87, the chemical ministry standard HGJ10-88), or the national standard (GB/T14383 – 1993), all of the orthogonal three. For engineering purposes, Y type shunt three links should be adopted according to piping requirements.
