Four advantages of anti-corrosion steel pipe in practical application
Anti-corrosion steel pipe is a metal body buried in the ground. However, due to the use of the environment, despite careful construction, the general steel pipe will inevitably age easily, and the steel pipe will still be damaged. To prolong the life of the steel pipe, it is n...Read more -
Analysis of the role of the steel flange
Steel flange is also called flange or flange. It is the part that connects the pipe to the pipe. connected to the pipe end. There are holes in the flange, and bolts can be worn to make the two flanges tightly connected. The flanges are sealed with gaskets. Flanged fittings ref...Read more -
Use scope and characteristics of hot dip plastic steel pipe
Hot-dipped plastic composite steel pipes are suitable for coal mine gas extraction, ventilation systems, fire water supply systems, central air-conditioning HVAC circulating water pipes, industrial water supply and drainage, domestic water supply and drainage, gas and other ga...Read more -
Straight seam steel pipe diameter expansion technology and common detection methods
Expanding technology of straight seam steel pipe: 1. Preliminary rounding stage: the fan-shaped blocks are opened until all the fan-shaped blocks touch the inner wall of the steel pipe. At this time, the radius of each point in the inner tube of the steel pipe within the step ...Read more -
Tips to identify fake and inferior steel pipes
Shoddy steel pipes are prone to folding. Folding is a variety of fold lines formed on the surface of the steel pipe, and this defect often runs through the longitudinal direction of the entire product. The reason for the folds is that the counterfeit and inferior manufacturers...Read more -
Treatment measures for common problems in pre-welding of straight seam steel pipes
1. Wrong side. This is a common problem in pre-welding, and the wrong side is out of tolerance, which directly leads to the degradation or scrapping of the straight seam steel pipe. Therefore, it is required to strictly control the misalignment amount during pre-welding. When ...Read more -
How to correctly judge the thickness of stainless steel welded pipe
How to correctly judge the thickness of the stainless steel welded pipe refers to the wall thickness of the pipe. Tell everyone that the wall thickness of the stainless steel welded pipe will be attached to the pipe under normal circumstances. Customers can know the thickness ...Read more -
How to detect the corrosion performance of steel flanges
The use of steel flanges in industrial structural parts is mainly to improve the connection and keep the pipelines sealed without leakage. However, many steel flanges will corrode and age after being used for some time, thus losing their tightness. Therefore, it is very necess...Read more -
Horizontal fixed welding of thick-walled stainless steel pipes
Thick walled stainless steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. Stainless steel pipes are lighter in weight when they have the same bending and torsional strength. ...Read more
