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.

ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape and are used in various engineering purposes. They are round pipes welded from steel plates with longitudinal welds. Pressure welding is carried out under the action of squeeze rollers. The production process of welded steel pipes is simple, the production efficiency is high, the varieties and specifications are many, and the equipment is few, but the general strength is lower than that of seamless steel pipes. ERW pipes are commonly used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure.

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.

carbon steel round pipe tubecarbon steel pipe tubeare divided into seamless steel pipes and welded steel pipes.
seamless steel pipeis made of perforated whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking. According to the cross-sectional shape, the seamless steel pipe is divided into two types: round and special-shaped. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes.
