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.

3.Dimensional accuracy and excellent micro-structure uniformity.

4.High strength to weight ratio.
