The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of A588 Gr B HSLA steel plate, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.
The company has A588 Gr B HSLA steel plate advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience A588 Gr B HSLA steel plate, we have accumulated a large number of customers at home and abroad, and won unanimous praise.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the A588 Gr B HSLA steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A588 Gr B HSLA steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
The allowable temperature of A588 Gr B HSLA steel plate, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of A588 Gr B HSLA steel plate work, the actual stress of A588 Gr B HSLA steel plate under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of A588 Gr B HSLA steel plate under the temperature.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
