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 -
Some installation points about stainless steel pipe fittings
The installation method of stainless steel pipe fittings is the same as that of ordinary carbon steel pipe fittings, but there are some special requirements in certain processes. as follows: 1. When lifting stainless steel pipe fittings, they should not be in direct contact wi...Read more -
Characteristics and scope of application of thin-walled stainless steel pipe socket argon arc welding construction method
The socket argon arc welding construction method has the following characteristics: 1. The welding process does not require welding materials (replaced by expanded pipe edges). The stainless steel pipe is inserted into the pipe fitting socket, and the end of the socket is weld...Read more -
Advantages of straight seam steel pipes and steel structure applications
Straight seam steel pipe is a steel pipe welding process that is opposite to spiral steel pipe. The welding process of this kind of steel pipe is relatively simple, the cost of welding is relatively low, and it can achieve high efficiency during production, so it is relatively...Read more
