The pipeline steel coil P235GH steel hardness and plates are our main products. And the most popular standard for pipeline steel is API 5L. We mainly supply API 5L grade B (L245), API 5L X42 (L290), API 5L X46 (L320), API 5L X52 (L360), API 5L X56 (L390), API 5L X60 (L415), API 5L X65 (L450), API 5L X70 (L485) pipeline steel coil and plates. Those stteel grades have both PSL1 and PSL2 levels. PSL2 has more strict requirements than PSL1. Besides, we also supply API 5L grade A PSL1 and API 5L X80 PSL2 steel.

With the development of China's p235gh steel hardness market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of p235gh steel hardness products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < p235gh steel hardness steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished p235gh steel hardness product packaging.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the p235gh steel hardness plate should be derusted before cutting.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel p235gh steel hardness products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
