Over the years, the company has established a standard of BV grade E traffic boat steel steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to BV grade E traffic boat steel quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.
Low alloy structural steel, also known as ordinary low alloy steel, HSLA steel. BV grade E traffic boat steel, Low alloy steel plates are killed or semi killed steel plates. Low alloy steel plates have the advantages of high strength, better performance, saving material and reducing the weight of structure. The thickness range of low alloy steel plates is usually 4.5-200mm. Low alloy structural steel is mainly used for manufacturing bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc.
Compared with carbon steel, alloy steel has higher strength, better heat resistance, better low temperature resistance, better corrosion resistance and other advantages. Some of its work environment can not be adapted by carbon steel. Therefore, alloy steel is a common and important material in pressure pipeline. Low alloy steel, BV grade E traffic boat steel quenched and tempered steel, stainless steel, heat-resistant steel and low temperature steel are commonly used in pressure pipes.
we also provide the BV grade E traffic boat steel welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful BV grade E traffic boat steel welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.
13CrMo4-5 seamless pipe is a kind of pressure resistant seamless pipe in accordance with the European standard EN 10216-2. The chemical composition of 13CrMo4-5 seamless pipe is C 0.10-0.17, Si ≤ 0.35, Mn 0.40-0.70, P ≤ 0.025, S ≤ 0.020, Cr 0.70-1.15, Ni ≤ 0.30, Mo 0.40-0.60, Al ≤ 0.04, Cu ≤ 0.03. Mechanical properties of 13CrMo4-5 seamless pipe: tensile strength: 440-590 MPa, yield strength: ≥ 290 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. BV grade E traffic boat steel, 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.
After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
