What we can do in our testing center

Physis laboratory,Chemical spectrometerPressure blasting machine, Metallographic analysisSalt Spray Test

 

Delivery condition:

BK (+C) Cold finished/hard  No heat treatment after the last cold forming process.
BKW (+LC) Cold finished/soft  After the last heat treatment there is a light finishing pass (cold drawing).
BKS (+SR) Cold finished/stress relieve annealed.

After the final cold forming process the tubes are stress relieve annealed.

GBK (+A) Annealed.

After the final cold forming process the tubes are annealed in a controlled atmosphere.

NBK (+N) Normalized. 

After the final cold forming process the tubes are annealed above the upper transformation point in a controlled atmosphere

 

Production routing:

Quality carbon steel from bao steel etc big mill, cold drawing the heat treatment without oxidization , NBK condition.

Do nondestructive testing ,HT tests and do dipping oil antirust protection, Packed tube in wooden boxes.

 

Main feature:

High precision

Excellent brightness

No oxidization on outer and inner walls after heat treatment

High cleanness of inside wall

High pressure

No deformation after clod bending

No crack after flaring and flattening
