With the development of API5L-B pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially the advantages of welded pipe in the range of large-diameter group spacing are more obvious. In 2004, the output of API5L-B (L245) seamless line pipe was about 400,000 tons. The steel grade includes X42-70, P235GH boiler steel process, and the varieties include onshore line pipe and subsea line pipe.

The company specializes in the research and development, production and sales of p235gh boiler steel process 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 p235gh boiler steel process five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,p235gh boiler steel process rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the p235gh boiler steel process 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 p235gh boiler steel process strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

p235gh boiler steel process, Weathering steel plate is a kind of common steel plate. For ordinary steel plate, if it is used for a long time, it will contaminate the steel surface with a layer of rust, which will seriously affect the normal use of steel. Although the weathering steel plate will produce rust, this layer of corrosion is like a layer of dense oxide film, which is firmly attached to the steel surface to prevent the further corrosion of the base and steel. There are many weathering steel plate manufacturers will adopt some corrosion treatment methods.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
