SPIRAL STEEL PIPE PURPOSE

Spiral steel mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of the 20 key development products.
For the transport of liquids: water supply, drainage. Used for gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipe for bridges; piers, roads, buildings and other structures tube.
The main industrial use: also known as spiral or helical spiral steel pipe, is a low-carbon steel or low alloy steel strip at a certain helix angle (called molding angle) rolled into a tube and then the tube seam welding made up, it can narrow strip production of large diameter steel pipe. Spiral mainly for oil and gas pipelines, its specifications diameter * wall thickness. There spiral welding and double-sided welding, pipe should ensure that hydrostatic test, weld tensile strength and forming performance to meet the requirements.
