Welded pipe is a commonly used pipe connection method, widely used in industrial, construction, chemical, petroleum, natural gas and other fields. Its applications include but are not limited to the following aspects:

Industrial pipelines: Welded pipes are commonly used in industrial pipeline systems for conveying liquids, gases, steam and other media, such as in chemical plants, refineries, power plants, etc.

Building structures: Welded pipes can be used for the support, framework, load-bearing columns and other parts of building structures, for example, in the plumbing, heating, and ventilation systems of buildings.

Oil and gas pipelines: Welded pipes play an important role in oil and gas transmission pipelines, used for connecting, supporting, and transporting pipeline systems.

Automobile manufacturing: Welded pipes are also widely used in the automotive manufacturing industry for making vehicle body structures, exhaust systems, chassis, and other parts.

In general, welded pipes have a wide range of applications in the industrial and construction fields, and their stability and reliability make them an important choice for pipe connections.
