Test 100%, Size and surface checking 100%Other test item can be arranged as per request

DELIVERY CONDITIONS:

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 ASTM A106 Gr.A carbon capilASTM A106 Gr.A carbon capillary precision seamless steel pipe precision seamless steel pipe on)

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

Some samples of related steel grade

Other grades also availabe upon customer's request and market situation

Packaging workshop

Packaging is the ultimatee of product quality .we establish strict packaging quality

management system to improve packaging quality of products continuously and pack
products strictly in accordance with packaging standars and customer requirements.

Seamless Steel Pipe mills, volume should go through continuous annealing (CAPL unit) to eliminate cold hardening and rolling stress, or batch annealing reach the ASTM A106 Gr.A carbon capillary precision seamless steel pipe mechanical properties of the corresponding standard specifies. Seamless Steel Pipe surface quality, appearance, dimensional accuracy ASTM A106 Gr.A carbon capillary precision seamless steel pipe better than hot-rolled plate, and right-rolled thin product thickness is about 0.18mm, so the majority of users favor.
DFJBVHJBJH
Seamless Steel Pipe deep processing of high value-added products. Such as electro-galvanized, hot dip galvanized, electro-galvanized fingerprint resistant, painted steel roll damping composite steel, ASTM A106 Gr.A carbon capillary precision seamless steel pipe laminating steel plates, etc, so that the excellent quality of these products has a beautiful, high resistance to corrosion, has been widely used.
