Product Description
Zhengde API pipeline steel pipe is a pipeline pipe belonging to the
American Petroleum Standard. The pipeline pipe is used to transport
the oil, steam, and water pumped out of the ground to the oil and
gas industry enterprises through the pipeline pipe. Line pipes
include seamless pipes and welded steel pipes, and the pipe ends
have flat ends, threaded ends and socket ends; the connection
methods are end welding, collar connection, socket connection, etc.
The production of high-grade line pipes adopts micro-alloying heat
treatment process. The production cost of stainless steel seamless
pipes is obviously higher than that of welded pipes, and with the
improvement of steel grades, such as X80 and above steel grade line
pipes, there is no carbon equivalent limit. The conventional
process of seam steel pipe is difficult to meet the requirements of
users; all 12Cr1moV alloy pipe manufacturers are carrying out
scientific research work to improve the corrosion resistance of
their line pipes and stabilize the performance in low temperature
and high temperature environments.

Our Advantages
API
API is the English abbreviation of American Petroleum Institute.
The grade indicates: the first two digits of the minimum value of
the American unit yield strength. Take X80 as an example: X80 is
the minimum yield strength of pipeline steel pipe 80000psi (552MPa)
PSI English full name is Pounds per square inch. P is pound, S is
square, and I is inch. It can be calculated by changing all the
units into metric units: 1psi=6.895kPa=0.06895bar European
countries and other countries are accustomed to using psi as the
unit 1bar=0.1MPaM--thermomechanical controlled rolling (TMCP
controlled rolling and controlled cooling) N--normalizing
Q--Quenching and tempering (quenching + high temperature tempering)
X42NB/X60QS/X65MS/X65MO.
Performance requirements
API pipe requirements (uniformity and stability of performance,
dimensional accuracy, plate shape hardening, Bauschinger effect) to
withstand large static and dynamic loads, to withstand the impact
of oil flow erosion and corrosion, ambient temperature, and
geological conditions on steel properties. Installation Welding
quality. High plasticity and toughness, low ductile-brittle
transition temperature, good welding performance, excellent
resistance to hydrogen-induced cracking and sulfide stress
corrosion cracking.
Attention to detail
There shall be no cracks, scars, folds, air bubbles, inclusions and
delaminations on the surface that are harmful to use. The surface
of the steel strip is allowed to have pits, concaves, scratches and
other local defects whose depth or height does not exceed half of
the thickness tolerance. And the minimum thickness allowed by the
steel strip should be guaranteed. The depth of edge cracks and
other defects in the width direction shall not exceed half of the
allowable width deviation and the minimum width of the steel strip
shall be guaranteed. The surface of pipeline steel shall not have
defects such as scratches and scratches that may cause cracks in
ultrasonic testing.
Applicable scene
Execution standards of seamless steel pipes for oil and gas
pipelines: API 5L: GR.B (L245), X42 (L290), X46 (L320), X52 (L360),
X56 (L390), X60 (L415), X65 (L450), X70(L485). Main application:
used to make oil and natural gas pipelines. API 5L generally refers
to the pipeline steel plate - API 5L pipeline steel plate, the
pipeline steel plate is processed into a large-diameter pipeline
steel pipe to transport the oil, steam and water extracted from the
ground to the oil and gas industry enterprises through the pipeline
pipe. The application range of API 5L pipeline steel is gradually
expanding, especially the advantages of API 5L large-diameter
pipeline steel are more obvious, coupled with the cost factor, API
5L seamless steel pipe has occupied a dominant position in the
field of pipeline steel.
