Control of weld gap of malleable cast iron pipe fittingsStrip steel is fed into the welding pipe unit, and after multiple roller rolling, the strip steel is gradually rolled up to form a round tube blank with an open gap. The pressing amount of the extrusion roller is adjusted to control the weld ga

(l) Elbows should be long-radius elbows with a radius of curvature equal to 1.5 times the nominal diameter. Pipes that convey gas-solid or liquid-solid two-phase flow materials should use elbows with large radius of curvature.(2) For horizontal pipe reducer connections on corridors, if there are no

At present, there are two main methods in this regard, which are also the more skilled processes used by many pipe fittings manufacturers. We will briefly introduce them.1. Spray painting.

The reducer is one of the chemical pipe fittings and is used for the connection of two different pipe diameters. It is divided into concentric size head and eccentric head. When the projection of the two ports is concentric circles, it is called concentric reducer, and the projection of the eccentri
