What needs to be done before burying 3PE anti-corrosion steel pipes
Before burying 3PE anti-corrosion steel pipes, the surrounding environment needs to be cleaned up first. The surveying and laying-out personnel need to give technical instructions to the commanders and machine operators who participate in the cleaning work. At least one line o...Read more -
How to detect the corrosion performance of the flanges
The use of flanges in industrial structural parts is mainly to improve the connection function and keep the pipeline sealed without leakage. However, many flanges will corrode and age after a period of use, thus losing the sealing effect, so it is very necessary to perform ant...Read more -
Straight seam steel pipe the production temperature and purchasing precautions details
Straight seam steel pipe production temperature: In the process of producing straight seam steel pipes, the temperature must be strictly controlled to ensure the reliability of welding. If the temperature is too low, the welding position may not reach the temperature required ...Read more -
How should the surface of high-frequency welded steel pipes be treated
With the continuous development of my country’s economy, the country has vigorously developed the energy industry. Long-distance API oil and gas pipelines are an important way to ensure energy security. In the process of anti-corrosion construction of oil (gas) pipelines...Read more -
The principle of anti-corrosion steel pipes commonly used in industrial projects
Coating anti-corrosion is a uniform and dense coating formed on the surface of the rust-free metal pipe, which can isolate it from various corrosive media. Steel pipe anti-corrosion coatings are increasingly using composite materials or composite structures. These materials an...Read more -
What is the difference between the surface processing of spiral steel pipes and stainless steel pipes
Let’s first talk about the original surface of stainless steel pipes: NO.1 The surface that is heat treated and pickled after hot rolling. It is generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc., with a thicker thickness of 2...Read more -
Several reasons and solutions for steel plates caused by shearing
With the wide application of bending parts in machinery, steel structure, vehicle engineering, and other fields, in order to meet their product quality and production needs, their quality standards are gradually improved. CNC bending machines can use universal molds (or specia...Read more -
Flange welding can also produce perfect fish scale patterns, here are some precautions
If you want to get high-quality welds, you need to pay attention to the following issues during the assembly and welding of flanges. First, the assembly and connection of flanges and steel pipes The assembly quality of flanges and steel pipes not only affects the strength and ...Read more -
Full-electrode arc welding process for large-diameter steel pipes
Most of the large-diameter thermal pipelines are now made of low-carbon steel spiral pipes. The general requirement is: in the weld quality inspection of the rotating weld and the fixed weld, the sampling should reach level II or above. The operation process is introduced as f...Read more
