Product Description

Precision pipe is a kind of seamless steel pipe with high precision and high brightness produced by cold drawing or cold rolling process. Its inner and outer diameter dimensions can be accurate to within 0.2mm, while ensuring bending and torsional strength, the weight is light, so it is widely used in the manufacture of precision mechanical parts and engineering structures. It is also used in the manufacture of mechanical structures, hydraulic equipment, automobile parts, steel sleeves and so on.

1. Smaller outside diameter.
2. High precision can do small batch production.
3. The cold-drawn product has high precision and good surface quality.
4. The transverse area of the steel pipe is more complicated.
5. Steel pipe performance is better, the metal is dense.

Tensile strength of precision steel pipe
Serial number	Given name		Sign of quantity	Unit symbol	implication
	intensity				Strength refers to the ability of a metal to resist plastic deformation and fracture under the action of external forces
1	Tensile strength		σb	MPa	When a metal specimen is stretched, the ratio of the maximum load to the original cross-sectional area of the specimen before breaking is called the tensile strength Pb Sigma b = - Fo Where Pb -- the maximum load of the sample before breaking (N) Fo -- sample original cross-sectional area (mm)
