SPA-H section steel Hot Rolled Plate 2020

SPV355 grade is a kind of steel for medium temperature pressure vessel of Japanese standard. The technical standard is JISG3115. It is widely used in petroleum, chemical, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, equipment and components such as liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, and turbine volutes.

The SPA-H section steel plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The SPA-H section steel products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

In actual processing applications, the processing SPA-H section steel thickness of flame cutting ranges from 6 to 200 mm, and the SPA-H section steel cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting SPA-H section steel with a certain thickness above 10mm.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and SPA-H section steel pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
