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.

ASTM A192 steel pipe is made of a high pressure seamless carbon steel used in super heaters, water wall panels, heat exchangers, condensers, marine application, refineries, paper pulping, petrochemical applications, pressure vessels, and general engineering applications. It is also used in coal, thermal and oil power generation plants. The A192 carbon steel pipes shall be made by the seamless process and shall be either hot-finished or cold-finished. Hot-finished tubes do not need to be heat treated.ASTM A192 is the same as ASME SA-192 and is the standard specification covering seamless carbon steel boiler and superheater tubes of minimum wall thickness for high pressure service.

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.
