Jiangxi spiral pipe丨Hunan spiral pipe price丨Changsha steel market

Spiral pipes are also called spiral steel pipes or spiral welded pipes. They are made by rolling low carbon structural steel or low alloy structural steel strips into pipe blanks at a certain spiral angle (called forming angle), and then welding the pipe seams. , which can produce large-diameter steel pipes from narrower strips. <3>Biology Also known as a spiral or spiral body. The outer diameter of the spiral tube is about 3 nanometers, the inner diameter is about nanometers, and the distance between adjacent spirals is about nanometers. Each week of the spiral tube is surrounded by nucleosomes. Histones are located on the inner surface of the spiral tube lumen and play an important role in maintaining the structure of the spiral tube. Nanofibers composed of nucleosomes spiral into 3-nanometer thick fibers, further compressing the length by a factor of 3.
Industrial pipes
Spiral pipes are mainly used in oil and natural gas transmission pipelines, and their specifications are expressed by outer diameter * wall thickness. Spiral pipes are either single-sided welded or double-sided welded. Welded pipes should ensure that the hydraulic pressure test, tensile strength and cold bending performance of the weld meet the regulations. The company is a professional manufacturer with complete models and specifications, and can also be customized according to customer requirements.
