How to cut carbon steel tube?
There are many ways to cut carbon steel tubes, such as oxyacetylene gas cutting, air plasma cutting, laser cutting, wire cutting, etc., can cut carbon steel. There are four common cutting methods: (1) Flame cutting method: This cutting method has the lowest operating cost, but consumes more fluid...Read more -
What is carbon steel pipe used for?
Carbon steel pipes should be made of steel castings or solid round steel through perforation, and then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in China’s seamless steel pipe industry. Key materials are mainly Q235, 20#, 35#, 45#, 16Mn. The most impor...Read more -
Advantages and disadvantages of carbon steel seamless pipe
Carbon steel seamless pipe (cs smls pipe) is a long steel pipe with hollow section and no joints around it; it is widely used in oil transportation, natural gas, gas, water and the transportation of certain solid materials.

Application field of spiral steel pipe for sewage discharge
Spiral pipe is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. It can be made with a narrower strip Steel produces large diameter steel pipes. Its ...Read more -
Factors affecting the yield strength of seamless pipe
Yield strength is an important concept in the field of seamless pipe mechanics. It is the stress value of seamless steel pipe when the ductile material yields. When the seamless steel pipe will deform under the action of force, the deformation at this time can be divided into two ways: plastic de...Read more
