EN 10210/S355 Seamless carbon steel pipe
Grade S355 is a low carbon manganese-containing steel alloy. This medium-strength carbon steel has both good weldability and good impact resistance. Grade S355 steel is also well suited for sub-zero temperature applications.

Product Parameter
Welded steel pipe,also known as welded pipe, is a steel pipe made of steel plate or strip after crimping and welding, generally 6 meters. Welded steel pipe production process is simple, high production efficiency, variety specifications, less investment in equipment, but the general strength is lower than seamless steel pipe.Straight seam welded pipe, steel pipe made of hot or cold rolled steel plate or steel strip coil welding, straight seam welded pipe on welding equipment are called straight seam welded pipe.

Product Show
S355 steel pipe has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low cold brittle critical transition temperature. The use of high-strength low-alloy steel can effectively reduce the weight of the structure, improve the strength and stiffness of the structure, and improve durability while reducing the thickness of the structure. S355 seamless steel pipes are commonly used in the production of bridges, ships, power station equipment, lifting and transportation machinery, machinery manufacturing and other engineering and welded structural parts that bear higher loads.

Carbon steel manufacturing process:
The smelting of carbon steel is usually carried out in converter and open hearth. Converters generally smelt ordinary carbon steel, while open furnaces smelt all kinds of high-quality steel. The technology of oxygen top blow converter is developing rapidly and it can replace open hearth furnace. The refined liquid steel is injected into the ingot mold to obtain various ingot. After the ingot is forged or rolled, it is processed into plates, strips, bars, and sections of various sectional shapes. Carbon steel is usually used directly in the hot rolled state. When used for manufacturing tools and various machine parts, it needs to be heat treated according to the requirements of use; As for steel castings, most of them are heat-treated.
Application
Carbon steel pipe with hollow section, a large number of pipeline used for conveying fluid, such as oil, natural gas, gas, water and some solid materials pipeline. It is widely used in the manufacture of structural and mechanical parts, such as oil drill pipe, automobile transmission shaft,bicycle frame and steel scaffolding used in construction.
