Advantages of Seamless Steel Tube

Seamless pipe is a hollow section, no joints around the strip steel. The total production of seamless pipe in the world has more than 110 countries of more than 1850 companies under more than 5100 production plants, including the production of oil pipelines in 44 countries of more than 170 companies under more than 260 plants.
Because of this characteristic of seamless steel tube, it is widely used in the transportation of oil, natural gas, gas, water and some solid materials. Compared with other steel tubes, seamless steel tubes have strong advantages in bending resistance. And the quality of seamless steel pipe is relatively light. It is a very economical cross section steel.

In addition, seamless steel pipe also has the following advantages:
1, seamless steel tube weight is light, its weight is only 1/5 of square steel.
2, seamless steel pipe corrosion resistance, acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact resistance and fatigue resistance, do not need regular maintenance, effective service life can reach more than 15 years;
3. The tensile strength of seamless steel pipe is more than 8-10 times that of ordinary steel, the elastic modulus is better than steel, and it has excellent creep resistance, corrosion resistance and shock resistance.
4, seamless steel pipe excellent mechanical properties, easy machining, etc.;
5, seamless steel pipe high elasticity, in the mechanical equipment to return to use, no memory, no deformation, and antistatic.

In recent years, seamless steel pipe is widely used in various industries, the market demand is too large, the production of seamless steel pipe enterprises, the product quality is uneven, so how to judge the quality of seamless steel pipe?
First of all, we need to know that the wall thickness of high-quality seamless steel will be particularly thick, because the thicker the wall thickness of the product, the more economic and practical, if the wall thickness is thinner, its processing cost will be substantially higher, and the resource cost will be higher. Secondly, the seamless steel process also determines its limitations, the general seamless steel precision is low and uneven wall thickness, low brightness inside the tube surface, size cost is high, and the inner appearance and pitting, black spot is not easy to remove; Third, its detection and shaping must be handled offline. Therefore, it has its advantages in high pressure, high strength and material for mechanical structure. We’ll find out as we use it.
