Selection requirements for submerged arc steel pipes:1. For pipelines with high peak shaving requirements, due to the uneven gas consumption of users, frequent fluctuations in pipeline pressure, and great alternating stress on the steel pipe, the existing defects in the pipe will expand under the al
The service life of the spiral welded pipe is related to the surface decarburization of the spiral welded pipe. If the surface is decarburized, the strength and wear resistance of the spiral welded pipe will be reduced, which will directly affect the service life of the spiral welded pipe. If the de
To prolong the service life of the spiral steel pipe, the first thing you should think about is to do its anti-corrosion work well. Because the pipes are mostly stored outdoors, they are most likely to rust after being exposed to wind and rain, so they are corroded, and the pipes can be processed an
The steel reducers belong to chemical pipe fittings and are used for the connection between two pipes of different diameters. According to different shapes, it is divided into two types: concentric steel reducers and eccentric steel reducers. The head material includes stainless steel head (304304l3

1 Judging from the surface, that is, in visual inspection. Visual inspection of welded joints is a simple procedure with a wide variety of inspection methods and is an important part of finished product inspection, mainly to find welding surface defects and dimensional deviations. Tests are generall
Precautions for storing straight seam steel pipes:Most of the merchants did not use the straight seam steel pipe soon after purchasing it. So is there anything we need to pay attention to in the storage of straight seam steel pipes? The staff of straight seam steel pipe manufacturers reminded that t

The steel pipe pipeline is the main transportation channel for production. The supply of materials and the flow of the process are realized by pipelines of different specifications, pressure levels, and shapes. There are countless elbows, flanges, and welds in the running pipeline. If one of the int
The connection method specification of galvanized steel pipe depends on the type of connection method. Generally, there are several types, such as flange connection, clamp groove connection, and welding. In the actual connection of galvanized steel pipes, welding is the most commonly used connection
