Seamless Steel Pipe

Alloy steel pipe is a kind of seamless steel pipe, its performance is much higher than the general seamless steel pipe, because this steel pipe inside containing Cr, high temperature resistance, low temperature, corrosion-resistant performance of other non-pipe joints not match, so the more extensive use of alloy tube in the petroleum, aerospace, chemical, electric power, boiler, military, and other industries.

Stainless Steel Pipe

Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instrumentation, and mechanical structural parts. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Welded Steel Pipe

Welded steel pipe refers to a steel pipe with a seam on the surface that is made by bending steel strips or steel plates into round, square and other shapes and then welding them. The blank used for welded steel pipes is steel plates or strip steel.

Coated Steel Pipe

Plastic-coated steel pipe, also known as plastic-coated pipe, steel-plastic composite pipe, and plastic-coated composite steel pipe, is a steel-plastic composite steel pipe with a steel pipe as the base. A layer of plastic anti-corrosion layer is welded on the inner surface of the steel pipe (bottom pipe) through spraying, rolling, dipping, and suction processes, or a plastic anti-corrosion layer is welded on the inner and outer surfaces.

Steel Hollow Section

Hollow section is an object of a certain geometry made of iron or steel and a material having a certain strength and toughness (such as plastic, aluminum, glass fiber, etc.) by rolling, extrusion, casting and the like. Including angle steel, channel steel, I-beam, square steel, H-beam, etc.is an object of a certain geometry made of iron or steel and a material having a certain strength and toughness (such as plastic, aluminum, glass fiber, etc.) by rolling, extrusion, casting and the like. Including angle steel, channel steel, I-beam, square steel, H-beam, etc.

API Series

There are many types of OCTG, including casing, tubing, line pipe, etc. They have different uses in different occasions. For example, casing is mainly used in the drilling process to protect the well wall from corrosion; tubing is responsible for transferring crude oil from the oil well to the ground; and line pipe is used for the main line in the oil and gas transportation process. These pipes are usually made of high-strength, corrosion-resistant steel to cope with harsh working environments.

Steel Pile Pipe

Steel pipe pile is a type of steel piling material. It is usually referred to the carbon steel pipe manufactured in seamless or welded (SSAW or LSAW), used for supporting and stabilizing the foundation of a building. So a pipe pile is a structural construction material.

Steel Pipe Fittings

The pipe fitting is a component that connects the pipe into a pipe. According to the coupling method, it can be divided into four types: socket pipe fitting, threaded pipe fitting, flanged pipe fitting and welded pipe fitting. The elbow is used for the pipe to turn; the flange is used to make the pipe The parts connected to the pipe are connected to the pipe end, the tee pipe is used for the place where the three pipes are collected, the four-way pipe(cross pipe) is used for the place where the four pipes are collected, and the reducer pipe is used for the connection of the two pipes of different pipe diameters.

Large Diameter Cold Drawn Tube

Cold-drawn steel pipes are a type of steel pipe classified by production process, distinct from hot-rolled (expanded) pipes. They are formed through multiple passes of cold drawing during the expansion process of billets or raw pipes, typically performed on single or double chain cold-drawing machines ranging from 0.5 to 100 tons.

Good Price Precision Steel Pipe

Precision steel tube is a high-precision steel tube material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components.

SAE1045 Special-shaped Tube

Special-shaped steel pipe is a non-circular cross-section profile made from seamless steel pipes through cold drawing, cold rolling or mold forming. It has high dimensional accuracy, good mechanical strength and stable performance. Common shapes include square, rectangular, oval, D-shaped, hexagonal, plum-shaped and other customized sections.

Hydralic Cylinder steel Pipe

Precision honed hydraulic cylinder pipe, high pressure & wear resistant. Suitable for hydraulic cylinder barrels, engineering machinery and industrial hydraulic systems. Stable quality, custom specifications available.

ISO CE Certified Stainless Seamless Pipe

Stainless steel seamless pipe is a pipe material with high corrosion resistance and high strength. It is made by heating a stainless steel blank to a high temperature and then using a piercing machine. This manufacturing method maintains the uniformity and consistency of the pipe, thus ensuring the quality and performance of the pipe.
