Welded pipes are typically referred to simply as "welded pipes." However, they can also be specified or categorized based on the welding process used to create them. For example:
Electric Resistance Welded (ERW) Pipe: This type of welded pipe is produced using the electric resistance welding process, where an electric current is passed through the edges of the steel sheets or strips to create a longitudinal weld seam. ERW pipes are commonly used in various applications.
Submerged Arc Welded (SAW) Pipe: SAW pipes are produced by the submerged arc welding process, which involves submerging the arc and the welding zone in a granular flux to create a high-quality weld. SAW pipes are often used for thicker-walled pipes and pipelines.
High-Frequency Induction Welded (HFI) Pipe: HFI pipes are created using high-frequency induction welding, which heats the edges of the steel strip or plate without direct contact with an electrode. This process is known for its speed and efficiency and is used for producing pipes of various sizes.
Gas Metal Arc Welded (GMAW/MIG) Pipe: GMAW, also known as MIG (Metal Inert Gas) welding, can be used to weld pipes, particularly those made of stainless steel and non-ferrous metals. It involves a consumable wire electrode and a shielding gas.
Gas Tungsten Arc Welded (GTAW/TIG) Pipe: GTAW, commonly referred to as TIG (Tungsten Inert Gas) welding, is used for welding pipes made of materials that require precise control and a high-quality finish, such as stainless steel and exotic alloys. It uses a non-consumable tungsten electrode and a shielding gas.
While these names specify the welding process used, "welded pipe" is the general term used to describe pipes that are produced by joining two or more pieces of metal through welding techniques. The specific name or category of welded pipe may vary depending on the industry and application.
