Quenching Treatment Of Seamless Steel Tubes

Find here details of P11 Seamless Steel Pipe on our website. Today we would like to talk about quenching treatment of seamless steel tubes.

Seamless steel pipe is an economical section. Originally produced and exported abroad, China introduced the advanced technology of the former Soviet Union in the 1950s and produced the first seamless steel pipe. Seamless steel tubes are mainly used in the fields of crude oil exploitation and processing, pipeline transportation, mechanical processing, large-scale stadium construction, and boiler manufacturing. Different application areas have different requirements for the performance of steel. In terms of crude oil extraction, the seamless pipe is used in the oil well pipe, so the seamless steel pipe used for the oil well pipe must be subjected to a quenching and tempering treatment.

As a P11 Seamless Steel Pipe Supplier, we know that there are two kinds of quenching processes for seamless steel tubes, one is water quenching in the tank, and the other is water quenching outside the tank. There are three methods for water quenching outside the tank, namely, water spray on the outside of the steel pipe, water spray on the inner surface of the steel pipe, and water spray on the inner and outer surfaces of the steel pipe. The water quenching process in the tank has the following methods: 1. Dip quenching, this It is the easiest method, but it is easy to bend the tube and the surface may form a vapor film. 2. Dip quenching and axial injection of water in the steel pipe, but the method has certain requirements on the length of the steel pipe, and the quenching performance exceeding a certain length is not good. 3. Dip quenching and axial spraying and outer spraying water in the steel pipe. The structure of the quenching device is complicated, and the nozzle is blocked by contaminants due to poor control. 4. Dip quenching and axially spraying water inside and outside the steel pipe. The device of the method is controlled by computer and has good quenching performance.
