Types of Welded Pipes

Home > Blog > Types of Welded Pipes

Welded pipe is a steel pipe made by welding. There are many types of welded pipe according to different classification standards. The following are the main classification methods of welded pipes:

Classified by production method--Including arc welded pipe, resistance welded pipe (high frequency, low frequency), gas welded pipe, furnace welded pipe, straight seam welded pipe, spiral welded pipe, etc. Among them, straight seam welded pipes are usually used to produce small and medium-diameter welded pipes, while spiral welded pipes are mostly used to produce large-diameter welded pipes.

Classified by weld form.--Including straight seam welded pipes and spiral welded pipes. The welding process of straight seam welded pipes is simple and low-cost, while spiral welded pipes are generally stronger and can use narrower steel plates to produce larger diameter welded pipes.

Classified by cross-sectional shape--Including round steel pipes, square steel pipes, rectangular pipes, etc. Steel pipes of different shapes are suitable for different application scenarios.

Classified by wall thickness--Thin-walled steel pipes and thick-walled steel pipes. The difference in wall thickness affects the load-bearing capacity and usage scenarios of welded pipes.

Classified by use--Including civil pipes, industrial pipes, etc. Civilian pipes are generally used in decoration, construction, structure, etc., while industrial pipes are widely used in petrochemical, papermaking, nuclear energy, food and beverage, pharmaceutical and other industries.

Classified by material--Including carbon welded pipe, stainless steel welded pipe, alloy welded pipe, etc. Welded pipes of different materials have different physical properties and applicable scenarios.

In addition, there are methods such as classification by standard and classification by end shape.
