Spiral welded pipe is a common type of steel pipe, and spiral welding technology is used in its manufacturing process. Spiral welded pipe has good strength and pressure resistance due to its unique structural characteristics and manufacturing process, and is widely used in fields such

Welded steel pipe weld seam style and characteristics According to the weld seam form and processing technology, welded steel pipe is mainly divided into straight seam welded pipe, spiral welded pipe and other special weld seam forms (such as girth welding, spot welding). Different weld

The caliber range of welded steel pipes is very wide. The specific caliber models vary according to different standards (such as national standard GB, American standard ASTM, European standard EN, etc.), but generally cover the following caliber classifications: 1. Nominal diameter (DN) Small diameter welded

The following lists the various materials commonly used for welded steel pipes, covering common international standards: 1. Carbon steel materials 1. Ordinary carbon structural steel: - Q195, Q215, Q235, Q255, Q275 (Chinese standard) - SS330, SS400, SS490, SS540 (Japanese standard JIS G3101) - ASTM A53

Welded pipe, also known as welded steel pipe, is a type of steel pipe that is formed by bending steel plates or steel strips into shapes and then connecting them into pipes through welding processes. It is a type of steel pipe widely used in

Spiral welded pipe is a steel pipe manufactured by spiral welding technology. Spiral welded pipe is usually used to transport fluids such as oil, natural gas, water, as well as in structural engineering and bridge construction. The production method of spiral welded pipe is to

Seamless steel pipe and welded steel pipe are two common types of steel pipes, which have significant differences in manufacturing process, performance, application areas, etc. Seamless steel pipe manufacturing process: Seamless steel pipe is made directly from a whole piece of metal through processes such

Straight seam welded pipe (LSAW) and spiral welded pipe (SSAW) are two common types of welded steel pipes, which are widely used in oil and gas transportation, construction, infrastructure and other fields. Straight seam welded pipe (LSAW) Production process 1. Raw materials: steel plate or

Spiral seam submerged arc welded steel pipe is formed by bending hot-rolled strip steel into a spiral shape, and the inner and outer seams are welded by submerged arc automatic welding to form a spiral seam steel pipe (also called spiral welded pipe, spiral
