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.

Oil casing is used to support the oil, gas wells of steel pipe, in order to ensure the drilling process and the completion of the entire well after the normal operation. Each well has several layers of casing depending on the drilling depth and geology. Casing down to use cement cementing, it and the tubing, drill pipe is different, can not be reused, a one-time consumption of materials. Therefore, the casing of the total consumption of more than 70% of the wells. Casing according to the use can be divided into: catheter, surface casing, casing technology and oil casing.

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.

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.

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.
