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

In the fluid piping system, the valve is the control element, its main role is to isolate the equipment and piping system, regulate the flow rate, prevent backflow, regulate and discharge pressure. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes and bimetal composite pipes, coatings and coated pipes to save precious metals and meet special requirements. There are many kinds of stainless steel pipes, different uses, different technical requirements, and different production methods.

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.

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

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.

The oil cracking pipe is a kind of long steel with hollow section and no joints around, and the oil cracking pipe is an economic section steel.

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.
