S690QL1 specification equivalent EN naterial

API 5L is a specification for pipeline steel pipe formulated by the American Petroleum Institute. The main steel grades in API 5L are: A, B, X42, X46, X52, X56, X60, X65, X70, X80, X90, X100, X120, etc. In API standard, pipeline steels are divided into PSL1 and PSL2. In the standard, there are slight differences in chemical composition, S690QL1 specification mechanical properties, inspection items, acceptance standards, delivery status, etc between PSL1 and PSL2 steel. For example, API 5L PSL1 X42 requires an upper carbon limit of 0.26, while API 5L PSL2 X42 requires an upper carbon limit of 0.24.

The company specializes in the research and development, production and sales of S690QL1 specification seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has S690QL1 specification five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,S690QL1 specification rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Last year, the technicians in the automation department of BBN STEEL closely combined the needs of the production line, based on the big data platform. It has successively developed more than 10 industrial software such as intelligent boiler combustion system, equipment full life cycle system, and integration of environmental protection management and control, which provide efficient and intelligent support for comprehensive support of high-end production line production and lays a solid foundation for high-quality development.

The strength level of traditional spring steel is difficult to meet the requirements of modern industrial development. As we all know, the mechanical properties of S690QL1 specification, spring steel depend on the heat treatment process under the premise of material quality assurance, and the heat treatment process should also be determined according to the material itself. An important way to increase the strength of spring steel is to give full play to the role of alloying elements to achieve the best alloying effect.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
