Pipe fittings are a key component in a pipe system that connects, transforms, controls and supports pipes. They play a vital role in a variety of industrial sectors, including petroleum, chemicals, power, metallurgy, shipping, and construction.

Schedule 40 carbon steel pipe is a medium specification pipe, and Schedule (SCH) is a unit of measurement for the nominal wall thickness of the steel pipe.

Welded steel pipes are often used in industrial production, mechanical manufacturing and daily life, and welded steel pipes have an obvious feature - clearly visible welds. The treatment of the weld is a very important link, which can directly affect the service life and safety performance of the steel pipe.

ERW steel pipe and seamless steel pipe are two common types of steel pipe, they have significant differences in production process, performance, and application scenarios.

Annealing treatment is an important heat treatment tool in the manufacturing process of seamless steel pipe, which is often used to improve the mechanical properties of steel pipe, eliminate internal stress and improve processing performance. Annealing can eliminate certain defects caused by hot working of steel, or prepare for later cutting and final heat treatment.

Straight Welded steel pipes can be divided into two main types according to the welding method: ERW (Electric Resistance Welded Pipe) and LSAW (Longitudinal Submerged Arc Welded Pipe). The two have significant differences in production process, raw material selection, welding method, weld quality and appearance, and are suitable for different engineering needs.

The spiral submerged arc welded steel pipe used in the drainage system is exposed to humid air, soil and other corrosive environment for a long time, and is prone to corrosion. In order to extend its service life and ensure safety and reliability, comprehensive anti-corrosion measures are required.

Flange is an important pipe connection component, which is widely used in industrial pipe system. Carbon steel flanges and stainless steel flanges are the two most common types, and they each have their own characteristics and play an important role in different application scenarios.

Seamless steel pipe, an indispensable component in many industries, is a cylindrical pipe with no welded joints or joints along its length.

A low carbon steel black square tube is a hollow square metal component made of low carbon steel with a black surface. Low carbon steel black square pipe has become one of the important materials in modern industry and construction because of its excellent performance, economic cost and wide applicability.

Seamless steel pipe because of its excellent performance, known as "industrial blood vessels", it is the basic components of many industries, in the oil, natural gas, chemical, energy, boiler manufacturing and other fields have an irreplaceable position.

A flange is a component that connects pipes, valves, pumps, and other equipment to form a piping system and facilitate cleaning, maintenance, and replacement. The shape of the flange is usually circular, and it is usually used in pairs to connect with the pipeline or equipment through bolts and gaskets to ensure its mechanical strength and tightness.

mild steel black pipes is a kind of pipe made of mild carbon steel, because its surface has a layer of black oxide film, so it is called black pipes. This layer of oxide is naturally formed during the manufacturing process, and the black appearance indicates that the surface has not been galvanized or other surface treatment.

A stainless steel elbow is a pipe fitting used to change the direction of fluid in a piping system. It is widely used in industries that require high corrosion resistance, durability and strength. Stainless steel elbows are usually available in the form of 45°, 90° and 180° angles to meet different pipe layout and design needs.

SSAW steel Pipe (Spiral Submerged arc-welded Pipe) is a kind of steel pipe made by coiled steel plates into billets in a spiral shape and Welded by double-sided Submerged Arc welding technology. The Angle of spiral welding makes the weld of the pipe spiral distribution, uniform distribution, which is conducive to withstand greater internal and external pressure.
