As a conveying pipe, steel pipe can be widely used to transport oil, gas, water, and other fluids. So steel pipe is known as the "blood vessel" of industry.

Steel pipe is an important material in the military industry, which can be used to manufacture gun barrels, barrels, and other weapons. With the development of aviation, missile, atomic energy, and space technology, the demand for precision, thin wall, and high strength steel pipe is increasing rapidly. A steel pipe made of a single piece of metal without any welding cracks on the surface is called "seamless steel pipe". According to the different production modes, it can be divided into cold rolled pipe, hot rolled pipe, extrusion pipe, pipe jacking, cold drawn pipe, and other types.

When purchasing seamless steel pipes, I believe that everyone has a misunderstanding: expensive is good! But in many cases, we will spend a lot of money but never achieve the desired effect. Seamless steel pipe with excellent technology is undoubtedly the best choice.

When purchasing, observe the sandwich layer rust of the seamless steel pipe. You can start from the cross-section of the pipe head, and if there is rust, be sure to wipe and clean it. If you look closely, you'll see that it has welding areas. Any planing or grinding will leave a mark, and in some places, it will be very obvious. Removing rust with tools, welding marks will be more obvious.

Be sure to read the manual carefully, and check whether seamless steel pipe meets the requirements of the standards.

Conduct flaw detection and composition inspection of seamless steel tubes to check whether the composition of steel tubes conforms to the standard rules.

Be sure to pay attention to the small details of the seamless steel pipe, and do not believe that "high price is the hard truth".
