The alloy pipe has a hollow cross-section and is widely used as a pipeline for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and some solid materia

Alloy steel pipe is defined by its material rather than by its forming route, and it is chosen where carbon steel cannot hold strength, creep resistance or toughness at the operati

According to the use, it is divided into general welded pipe, galvanized welded pipe, blown oxygen welded pipe, wire casing, metric welded pipe, roller pipe, deep well pump pipe, a

The production process is simple, the production efficiency is high, the cost is low, the development is fast.

Corrosion in welded steel pipe is controlled by the steel composition, the quality of the weld seam and the chemistry of the service environment. Chromium, nickel, molybdenum and c

Welded steel pipe is so common today that its history is easy to underestimate. Yet the ability to join a strip of steel into a continuous tube was one of the enabling technologies
