Processing technology of spiral steel pipe

　　Spiral steel pipes the diameter is from 219mm to 3500mm and thickness normally from 5 to 30mm. Spiral steel pipes is mainly used in oil and gas pipe lines and other fluid pipes.

　　Spiral steel pipe stack should be raised at the end of high, strong, smooth, to prevent damp or deformation of materials;The same kinds of materials have been stacked according to storage;Open-air spiral steel pipe stack, the following must be a wooden mat or stone, a little tilted stack to facilitate drainage, and pay attention to the material placed straight to prevent bending deformation;

　　1200mm diameter carbon welded spiral steel pipe stacking height, artificial homework should be more than 1.2m, mechanical work no more than 1.5m, stack width no more than 2.5m.
