Seamless pipe is a hollow section, no joints around the strip
steel.
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.
