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:

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

Color : Gray with white

Application:

Hydraulic system

Automobile
