Product Description

High Precision Mechanical Structural Seamless Steel Tubes


Precision Seamless Steel Tubes for Mechanical Structural

The difference between precision steel pipe and seamless pipe:

1. the seamless steel tube with obvioue difference is that dimensional accuracy, can be up to 0.1mm.
 
2. high precision steel pipe diameter surface finish, the customer without processing can be used directly and ordinary seamless steel tube to the customer and lather, polishing processing.

Features:
 
Tube inside and outside the wall without oxidation layer, under high pressure, no leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks, surface rust proffing.
 
1. The smaller outer diameter
 
2. High precision to do small batch production
 
3. Cold rolled finished products of high precision, good surface quality
 
4.The steel pipe transverse area is more complex
 
5. Steel pipe is superior performance, dense metal
