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.

Main Feature

1. The smaller outer diameter2. High precision to do small batch production3. Cold drawn finished products of high precision, good surface quality4.The steel pipe transverse area is more complex5. Steel pipe is superior performance, dense metal

Advantage
Internal and external walls without oxide layer
to withstand high pressure without leakage
Cold bending deformation
Flattening without cracks
best bright finish
Delivery condition:1. NBK(+N)after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium2. GBK(+A)after cold forming, annealing in non oxidizing medium protective gas3. BK(+C)the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee4. BKW(+LC)after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)5. BKS(+SR)have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again
