Delivery condition:

 

The tubes can be produced in the following delivery conditions:

BK (+C) Cold finished/hard (cold finished as drawn).

No heat treatment after the last cold forming process.

 

BKW (+LC) Cold finished/soft (lightly cold worked)

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. (Mainly focus on)

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:
