At present, the most common pipe cutting method for spiral steel pipe manufacturers is plasma cutting, which will generate a large amount of metal vapor, ozone, and nitrogen oxide smoke during cutting, which will seriously pollute the surrounding environment. The key to solving the root problem is h
1. Different power sources: the same energy is required, but the power sources of crude oil pipelines and natural gas pipelines are different. The power source of the crude oil pipeline is a centrifugal pump, and the power source of the natural gas pipeline is the compressor.2. Different temperature

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
