Advantages:


1.Higher Working Pressure Capbility: Under same working pressure, the stress to the sprial welding seam is 75%-90% of striaght seam, so the sprial pipe can bear higher working pressure. Therefore, the wall thickness of sprial pipes can be 10%-25% less than stright seam pipes under same working pressure, saving costs for the material;

2. Good Precision: the tolerance of diameter is usually with in 0.12%, the deflection is less than 1/2000, and ovality is less than 1%, so the sizing and strenghtening works can be saved;

3. High Utilization: the sprial pipes can be continually produced, with less loss of cutting head and end, which can rise the utilization of 6%-8%;

4. Full Range of Sizes: the  sprial pipes are ranging from small diameter to large diameter, easier operation than straight seam pipe;

5. Mechanization and Automation
