What is the specification of Q370R pressure vessel steel plate?

1. Introduction to Q370R pressure vessel steel plate: Q370R steel plate is a medium and low temperature pressure steel plate, which is widely used in petroleum, chemical industry, power station boilers and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, and nuclear reactors. Equipment and components such as pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, and turbine volutes.

2. How to express the grades. The grades of carbon steel and low-alloy high-strength steel are indicated by the yield strength value and the first letter of the Chinese pinyin of the word "buckle" and the word "Rong" of the pressure vessel. Such as: Q370R.

3. Size, shape, weight and allowable deviations. The size, shape and allowable deviations of Q370R pressure vessel steel plate shall comply with the provisions of GB/T 709-200; according to the requirements of the buyer and the agreement between the supplier and the buyer, steel plates with stricter deviations can be supplied; steel plates are based on theory For delivery by weight, the thickness used for theoretical weight calculation is the arithmetic average of the maximum and minimum allowable thickness of the steel plate, and the density of the steel plate used for calculation is 7.85g/cm3.

Fourth, surface quality The surface of the Q370R pressure vessel steel plate is not allowed to have defects such as cracks, bubbles, scars, folds and inclusions that are harmful to use. There shall be no delamination on the side of the steel plate.
