The main steel plates for oil and gas pipelines are X42, X46, X52 (L360), X56 (L390), X60 (L420), X65 (L460), X70, X80. The specification range of steel plate used by the company for oil and gas pipelines: thickness 8mm-60mm. It can produce additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) steel plates API 5L PSL1 X52 size range, and can also provide Z-direction performance steel plates according to ASTM A770 and other standards.
The tempering of API 5L PSL1 X52 size range steel plate, the hardened steel will be reheated to a certain temperature, and then a certain method of cooling is called tempering.Its purpose is to eliminate the internal stress caused by quenching, reduce hardness and brittleness, so as to achieve the desired mechanical properties. Tempering is divided into three types: high temperature tempering, medium temperature tempering and low temperature tempering.Tempering and quenching, with the use of normalizing.
The company has always been adhering to the business philosophy of "integrity-based, responsibility oriented, quality first, reputation first" and is committed to building a world-class steel materials and service provider. We will continue to work hard to carry forward the enterprise tenet of "quality is the life of the enterprise, survival by quality, development by reputation", and become an enterprise with strong vitality! We always keep it in mind that profit is important to enterprises. But what counts more is social responsibility.
When automatic steel plate cutting is carried out, the distance difference between the steel plate hanging from the steel plate to the gas cutting platform should be adjusted to within 5mm.When semi-automatic cutting is carried out, the guide rail should be placed on the plane of the steel plate to be cut, and then the cutting machine should be placed lightly on the guide rail.Make one side of the cutting torch face the operator, choose the cutting nozzle according to the thickness of the steel plate, adjust the cutting straightness and cutting speed.
