Synopsis of Process Routing
 
quality carbon steel-cold drawn-heat treatment without oxidization (NBK status)- nondestructive testing, inthe wll honing andinside flushing under the high pressure- antirust oiling outside surface- plastic coaapin on both ends.
main features
high precision, excellent brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness ofinside wall, the steel tube is able to withstand high pressure, no deformation afer cold bendingm no crack after flaring and flattening, the complicated geometrial forming and machining can be realized, color of tube, gray with wihite.

Specifications
 

1.The difference between precision seamless steel tubes and seamless steel pipe:

1) Seamless steel pipe main characteristic is a welding seam, can withstand greater pressure.Products can be very rough as-cast or cold dial.

2) Products of precision seamless steel tube is appeared in recent years, mainly is the inner hole, the size of the outer wall with strict tolerance and roughness.

2.Precision seamless steel tube features:

1) The outer diameter smaller.
2) High precision to do small batch production. 
3) Cold drawn 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.
