Steel Pipe

black metal tube is made of hot rolled or cold rolled strip steel or coil plate as base material by cold bending forming and then by high frequency welding made of square section shape and size of steel. In addition to the thickening of the wall, the corner size and edge flatness of hot rolled extra-thick wall square tube reach or even exceed the level of resistance welding cold forming square tube. Good comprehensive mechanical properties, weldability, cold, hot working and corrosion resistance, with good low temperature toughness.
The factory produces tens of thousands of tons of black metal tubes every month and exports them. We have the ability to do anything, quality products and the best ex-factory price.

ASTM A334-1.6 Steel Pipe is produced and exported in our factory. According to the production process of the factory, there are hot rolled ASTM A334-1.6 Steel Pipe and cold rolled ASTM A334-1.6 Steel Pipe.And we have two kinds of seamless and welded according to customer requirements.
Our production of over 10,000 mt per month can be exported. We use containers in general and we guarantee that the Steel tubes of ASTM A334-1.6 Steel Pipe are not corroded.

A335-P22 Alloy Steel Pipe :
A335-P22 Alloy Steel Pipe Production of steel pipe is generally grouped into two categories: Welded and Seamless. There are many methods of producing steel pipe in current use, however, most of the pipe produced is made either by the seamless, electric resistance weld (ERW) or spiral weld methods Continuous weld and double submerged arc weld are other common methods of manufacture.
As a professional steel manufacturer, we produce thousands of tons of ASTM A335-P22 alloy tubes every month, and export a large number of high-quality products.

A335-P12 Alloy Steel Tube is the part of ASTM A335, The pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding. The steel material shall conform to chemical composition, tensile property, and hardness requirements.
A335-p12 Alloy Steel Tube has two kinds of seamless and welded, common hot rolled seamless Steel Tube, and tens of thousands of tons are produced and exported every month.

ASTM A335-P5 alloy steel pipe is a ferritic high temperature alloy steel seamless pipe, P5 heat resistant steel can resist the corrosion produced in the process of petroleum cracking, P5 heat resistant steel used for reheating steam pipe, petroleum cracking pipe, boiler hanger, steam turbine cylinder bushing, pump parts, valves, piston rod, high-pressure hydrogenation equipment parts, fasteners, etc.
ASTM A335-P5 Alloy Steel Pipe generally has hot rolling and cold rolling technology in production. Our factory produces tens of thousands of tons of Steel Pipe every month and exports it. We have the ability to do anything.

API 5L X60 Pipeline Seamless and Welded Steel Pipe for Pipeline Transportation Systems in the Oil and Gas Industry. API 5L X60 pipes are suitable for conveying gas, water and oil.
Our factory produces thousands of tons of API 5L X60 Pipeline Steel every month and exports it. We can do anything.

API 5L X65 Corrossion Resistant Steel Pipeline is also called ISO 3183 L450 pipe, it is a high level grade pipe in API 5L (ISO 3183) specifications, used for oil and gas transmissions. The reason we call it X65 pipe or L415 pipe is because it's minimum yield strength required in 65000 Ksi or 450 Mpa.
API 5L X65 Corrossion Resistant Steel Pipeline with seamless and screw welding process. Our factory can produce tens of thousands of tons per month and export them.

Thick-walled steel pipe, the steel pipe whose outer diameter to wall thickness ratio is less than 20 is called thick-walled steel pipe. It is mainly used for petroleum geology drilling pipe, cracking pipe, boiler pipe, bearing pipe, automobile, tractor, aviation high-precision structural pipe and so on.
The key to the quality of thick-walled steel pipe is the uniformity of wall thickness. If the wall thickness of thick-walled steel pipe is not controlled, it will directly affect the quality and use of steel pipe. Thick-walled steel pipe and large-caliber thick-walled steel pipe are generally used in various mechanical processing and thick-walled parts processing

The manufacturing methods of ASTMA106-99 High Pressure Steel Pipe are divided into hot rolling (extrusion, expansion) and cold drawing (rolling). High pressure steel pipe has good comprehensive mechanical properties at room temperature and high temperature, strict quality control, suitable for various working conditions under high pressure. High pressure steel pipe is mainly used in boiler, diesel engine high pressure tubing, fertilizer equipment and pipelines.
