Advantages and principles of stainless steel compression pipe fittings and construction precautions
First, the principle of clamped stainless steel pipe fittings 1. Principle of pull-out resistance: The middle position of the compression-type pipe fitting is small, but the two ends are large, and the pull-out resistance is >3.0mpa; 2. Leak-stopping principle: An O-shaped ...Read more -
Selection requirements for submerged arc steel pipes
1. For pipelines with high peak shaving requirements, due to the uneven gas consumption of users and frequent pipeline pressure fluctuations, the steel pipes bear great alternating stress, and the existing defects in the pipes will expand under the alternating stress. If you c...Read more -
Reasons for slag inclusion during the production of anti-corrosion spiral steel pipes
Anti-corrosion spiral steel pipes are made of low-carbon structural steel rolled into tube blanks according to relative spiral angles, and then the pipe seams are welded together. They are also called spiral steel pipes or spiral welded pipes. Anti-corrosion spiral steel pipe ...Read more -
