Q235B/Q345B Large Diameter and Wall Thickness Water Pipe / Welded Steel Pipe
During the 20th Century, advancements were made in steel pipe, in the economy of production and the quality of the product. Noteworthy are the machines and technology for cold-forming of flexible pipe from coils of sheet steel with automated spiral welds. Great strides were made in quality control, testing, joints and protective coatings.
Welded steel pipe is available in wide ranges of sizes and properties of the steel. Included in this manual are the design criteria for steel pipe up to 240 inch (6,000 mm) in diameter under either internal or external pressure. The requirements of buried flexible pipe are: strength, ease of installation, high flow capacity, leak resistance, long service life, reliability and versatility, and economy. The properties of steel are well adapted to these seven requirements of buried pipelines.
