high precision steel pipe Advantage

1. 1. Light weight: Precision steel pipe is light in weight, and its weight is only 1/5 of square steel.
2. 2. Corrosion resistance: Precision steel pipes are corrosion-resistant, resistant to acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact resistance and fatigue resistance, do not require regular maintenance, and have an effective service life of more than 15 years.
3. 3. High tensile strength: The tensile strength of precision steel pipes 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 earthquake resistance.
4. 4. Excellent mechanical properties: Precision steel pipes have excellent mechanical properties and are easy to machine.
5. 5. High elasticity: Precision steel pipes are highly elastic, can be used repeatedly in mechanical equipment, have no memory, do not deform, and are antistatic.
