Flange, also called flange flange disc or flange. The flange is a part connected between the shaft and the shaft, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures.

Seamless steel pipe is perforated by the whole round steel, and the steel pipe with no weld on the surface is called seamless steel pipe. According to the production method, the seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe, pipe jacking and so on.

In a piping system, a bend is a pipe fitting that changes the direction of the pipe. According to the Angle, there are 45° and 90°180° three most commonly used, and other abnormal Angle elbows such as 60° are also included according to engineering needs. Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics

Boiler tube refers to the two ends of the open and has a hollow section, the length and the surrounding of the relatively large steel, according to the production method can be divided into seamless steel pipe and welded steel pipe, steel pipe specifications with external dimensions (such as outer diameter or side length) and wall thickness, its size range is very wide, from a small diameter of the capillary tube to a diameter of several meters of large diameter pipe. Steel pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes.

Titanium tube has light weight, high strength and superior mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and conveying pipelines. Many nuclear power industries use titanium tubes as standard tubes for their units.

Pup jointis a pipe of non-standard length used to adjust the length of tubular strings to its exact requirement.

A Tee is a pipe fitting which is shaped like a "T" and has two outlets at 90° to the single inlet connection. Tees are generally used to combine or split a fluid flow.

Fluid steel pipe is a kind of steel pipe with a hollow section and no weld from end to end. The fluid steel pipe has a hollow section and is widely used as a pipe for conveying fluids to transport oil, natural gas, gas, water and some solid materials.
