normal range
Special range
Main Feature
1.high precision, saves the loss quantity when machining users
2.Specifications, wide range of applications
3.cold rolled finished products with high precision, good surface
quality and good linearity.
4.Steel pipe diameter can be made into hexagonal
5.steel pipe superior performance, comparatively 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 medium
2. GBK(+A)
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C)
the final heat treatment after cold forming, therefore small steel pipe
plastically, the plastically degree does not guarantee
4. 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
welcome to my company
TIANJIN DALIPU OIL COUNTRY TUBULAR GOODS CO.,LTD is a modern professional
industry and trade combined enterprise, specializing in producing and trading
seamless steel pipes.
The main products of our company are the oil casings and oil pipelines. We not

include from 60.3 to 508mm; the steel grades include J55, K55, N80, L-80, P-
110, C-90, C - 95, T-95 and so on; the merchantable claspers are STC , LTC, BTC
, etc.
The implemental standards for the oil pipelines are API 5L; the specifications
include from 219.1 to 2032mm; the steel grades include Gr.B, X42,
X46,X56,X60,X70,X80 and so on.
At the same time we also supply a large number of seamless steel pipes in
different uses, such as fluid pipes and structural pipes. Besides that, we have
many years of co-operation ships with Tianjin Large Seamless Company, Baogang
Steel Pipe Company, Anshan Steel Pipe Company, which make sure our abundant
resources.
