Do you know how many kinds of welded steel pipes there are?

　　What is welded steel pipe? Just as its name implies, welded steel pipe is manufactured by steel belt or steel plate bending the barrel, and then using flux to weld, there is a weld seam on the pipe. Common types of welded steel pipe are ERW steel pipe, LSAW steel pipe, SSAW steel pipe, and so on.

　　General steel pipe is used to transport low-pressure fluid and easy to weld the other soft steel. Usually, the length of the delivery of 4-10m is actually different, according to the provisions of the wall thickness the pipe has two kinds of steel, the spiral seam and the straight seam.

　　SSAW steel pipe adopts the low carbon construction steel strip or low alloy structural steel strip to roll into a tube, and then weld together, to product large diameter SSAW steel pipe. SSAW steel pipe is mainly used for oil and natural gas pipeline, SSAW steel pipe adopts single-sided welding and double-sided welding. Welded steel pipe should ensure that water pressure test, weld tensile strength and cold bending performance can meet the requirements.

　　LSAW steel pipe is made by using strip steel as raw materials and doing longitudinal welded in the high-frequency welding equipment(hence the name due to the weld forms a straight line). In accordance with the use of different, there are different production process (can be divided into scaffolding tube, fluid tube, wire casing, bracket tube, fence tube, etc.).

　　Another commonly-used kind of welded steel pipe is ERW steel pipe. ERW steel pipe is the abbreviation Electric Resistance Welded Pipes. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes. ERW steel pipe is manufactured by rolling metal and then welding it longitudinally across its length. ERW steel pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured up to 24”OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.
