Welcome to inquire! Contact: pay by blog. Spiral Pipe to play in a variety of gases, liquids transport a significant aspect brings a very important influence of large diameter spiral pipe GB for our life and production, thus become the concern and attention by the public facilities. Now with the user's cognitive spiral pipe more and more, and improve its development process are obtained in the course has advantages, etc., have become the trust of consumers and select its key, Therefore, the current more and more users as well as for the development of spiral pipe had a keen interest in the application. In the process of China using standard spiral steel pipe standards, the principal stress direction of the spiral steel pipe, steel pipe in the axial direction that is indeed equivalent flaw length smaller than a straight seam pipe; secondly, because the pipeline are rolled steel, toughness greater isotropic , CVN values ??along the rolling direction than perpendicular to the rolling direction CVN value three times higher. As in pipe wall plus anti-corrosion coating, can increase the loop resistance GB spiral pipe manufacturers, adding corrosion current; an external DC power supply GB spiral steel pipe, steel pipe to soil constitute a negative potential, constitute cathodic protection, can eliminate the potential difference between the anode and cathode, from Basically abort abort the anode and cathode of the process.
