Product Description

Product Description

Seamless Steel Pipe:
The seamless steel pipe is made of perforated whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking.

Pipeline steel pipe is a specially treated steel pipe with many excellent performance and use characteristics. It is widely used in various industrial and civil fields, providing important support for social development and people's lives. The main uses of pipeline steel pipes will be introduced in detail below.

First of all, pipeline steel pipes are widely used to transport liquids. For example, oil, natural gas, water and other liquids are transported and distributed to various places through the pipeline system, which includes a large number of pipeline steel pipes. Pipeline systems usually need to withstand high pressure and temperature, and pipeline steel pipes have good pressure and temperature resistance, and can transport various liquids safely and reliably.

Secondly, pipeline steel pipes are also widely used to transport gas. Many chemical plants and energy companies use pipeline systems to transport gases, including hydrogen, oxygen, nitrogen, and more. These gases also need to withstand high pressure and temperature during transportation, so high-strength and corrosion-resistant pipeline steel pipes are required.

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.

Quality first: production and inspection in strict accordance with production standards;
Price advantage: discounts based on real market prices;
Transaction security: There will be no loss of customer funds;
After-sales guarantee: the customer's problem is our problem;
Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.
