Internal anti-corrosion treatment method of large-diameter spiral steel pipe
The construction of cement mortar fabric should usually be carried out after the spiral steel pipe is laid, the pressure test is qualified, and the soil is compacted according to the design requirements. Because the steel pipe has small rigidity and a thin wall, the pipeline m...Read more -
What are the requirements for stainless steel fluid pipes
Stainless steel fluid pipes are used to convey fluid substances and are used in food, pressure vessels, industrial transportation, and other industries. Pipelines for transporting fluids have very high requirements on technology, the most critical points are: 1. Requirements f...Read more -
Precautions for handling and storing stainless steel pipes at the construction site
After the thin-walled stainless steel pipes are packed and bundled, they should be stored in a dry and clean environment without corrosive gas, and should not be piled up with other items. Because the surface of stainless steel is relatively smooth and bright, and it is also a...Read more -
Straight seam steel pipe procurement method and processing method
Procurement method of straight seam steel pipe: 1. Purchasing needs to know the type of steel pipe 1) By type: straight seam steel pipe, seamless steel pipe, spiral steel pipe, etc. 2) Section shape classification of straight seam steel pipe classification: square pipe, rectan...Read more -
The difference between galvanized steel pipe and plastic-coated steel pipe
1. Galvanized steel pipe to make the molten metal react with the iron matrix to produce an alloy layer so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. To remove the iron oxide on the surface of the steel pipe, after pickl...Read more -
Technical characteristics of double-sided submerged arc welding spiral steel pipe
1. During the forming process of double-sided submerged arc welding spiral steel pipe, the deformation of the steel plate is uniform, the residual stress is small, and the surface does not produce scratches. Processed steel pipes have greater flexibility in the range of diamet...Read more -
How to perform daily maintenance on straight seam steel pipe
Long-distance oil and gas pipelines are an important way of energy security. During the anticorrosion construction process of oil and gas pipelines, the surface treatment of straight seam steel pipes is the key factor determining the service life of pipeline anticorrosion. It ...Read more -
What are the heat treatments of stainless steel welded pipes
During the production process of stainless steel welded pipe, intermediate heat treatment and finished heat treatment can be carried out. Because a bright surface without oxidation can be obtained, the traditional pickling process is canceled. The use of this heat treatment pr...Read more -
Is there any difference between HFW steel pipe and ERW steel pipe
The difference between ERW steel pipe (straight seam electric resistance welded steel pipe) and HFW steel pipe (high frequency welded steel pipe) is mainly the principle. As the name implies, resistance welding is a method in which pressure is applied through electrodes after ...Read more
