Introduction of socket pipe fittings

The socket pipe fittings are mainly divided into high-pressure pipe connection fittings which are formed by die-casting forging of round steel or steel ingots, and then formed by lathe machining, and the pp resin modified polypropylene low-pressure pipe is connected with the curved elastic double-ducted socket. Double-melt pipe fittings. Connection Type The socket connection series includes: socket […]

Master these methods, the valve is corroded without traces

Corrosion is one of the important elements that cause valve damage. Therefore, valve protection is an important issue to consider in valve protection. PetroChina and Sinopec talk about anti-corrosion: What is the corrosion of the valve? How to carry out valve anti-corrosion? What is the basis for the selection of corrosion-resistant valves? 1. Valve corrosion form The […]

Hot pressing process and testing standard for manufacturing stainless steel reducer

The stainless steel reducer is one of the chemical stainless steel pipe fittings and is used for the connection of two different pipe diameters. It is divided into stainless steel concentric reducer and stainless steel eccentric reducer. 1 Process for manufacturing stainless steel reducer     The stainless steel reducer has a Concentric Reducer, an Eccentric Reducer and a Reducing El-bow. The latter two stainless steel reducers are non-axisymmetric […]

Detailed introduction of the reducer

Pipe reducer for connection between pipes of two different pipe diameters. According to the shape, it is divided into two types: concentric small head and eccentric reducer. The different diameter pipe material includes stainless steel reducer (alloy steel, carbon steel reducer). The calculation method of the expansion arc length of the different diameter reducer: Concentric reducers, […]

Five factors affecting the brightness of stainless steel pipe fittings during annealing

Annealing is a heat treatment process in the processing of stainless steel pipe fittings. The pipe is slowly heated to a certain temperature for a sufficient period of time and then cooled at a suitable speed.   The brightness of the product after the production of stainless steel pipe fittings determines the quality of the product.
