Application of thin-walled stainless steel pipes
Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, and economical. The thin-walled pipes and the successful development of new, reliable, simple, and convenient connection methods have given them more irreplaceable advantages than other pipes. They w...Read more -
The difference between galvanized steel pipe and hot-dip galvanized steel pipe
A galvanized steel pipe is generally called a cold-plated pipe. It adopts an electroplating process and only the outer wall of the steel pipe is galvanized. The inner wall of the steel pipe is not galvanized. Hot-dip galvanized steel pipes use a hot-dip galvanizing process, an...Read more -
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 -
Spiral steel pipe packaging precautions
How to pack spiral steel pipes when transporting them has always been an issue that needs attention. Let’s talk about the precautions for packaging spiral steel pipes. 1. If the purchaser has special requirements for the packaging materials and packaging methods of spiral stee...Read more -
Spiral steel pipe connection method
1. Flange connection: Generally, flange connection is fast, easy to construct, and has simple tools, but it cannot meet most engineering requirements in terms of safety and sealing. Generally, spiral steel pipes with low pressure and pipes that are often moved are suitable for...Read more -
Factors affecting the accuracy and resolution of oil casing wall thickness detection
API standards stipulate that the internal and external surfaces of import and export oil casing shall not be folded, separated, cracked, or scarred. These defects should be completely removed, and the removal depth should not be less than 12.5% of the nominal wall thickness. P...Read more -
Why are 304 and 316 stainless steel pipe fittings magnetic
In real life, most people think that stainless steel pipe is non-magnetic and use magnets to identify stainless steel. This method is very unscientific. People often think that magnets absorb stainless steel to verify its quality and authenticity. If it does not attract non-ma...Read more
