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.

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.

LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated  is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diater. In the construction of high strength, high toughness and high quality long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick wall straight seam submerged arc welded pipes.

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.

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.

Application: For gas, water, transportation in Petroleum and natural gas industries
