Std Pipe Awwa C200 / Astm A53 Standard For Piling Construction

Introduction

piral steel pipe from the raw material into the workshop must after spiral steel pipe, spiral steel pipe before molding forming, spiral steel pipe in the whole production line all equipment finally combined into spiral steel pipe quality checks can be made, after double quality inspections department department and processing slightly, can be put into the market or network market sales. Spiral steel pipe adopts advanced double-sided submerged arc welding process, can be in the best position for welding, it is not easy to appear the wrong side and defects such as lack of penetration, welding, welding quality easy to control and position. Spiral steel pipe of the use of special welding process, welding can be in the best position for welding, no any mistakes, can ensure the eligibility of spiral steel pipe, to obtain the very good quality assurance. 

Spiral steel pipe forming process, the steel plate to uniform deformation, residual stress, surface not to produce scratches, so making spiral steel pipe, steel plate selection carefully surface to even don't have a scratch. Processing spiral steel pipe on the scope of the size of diameter and wall thickness is more flexibility, especially in the production of high grade thick wall tube, especially small and medium caliber thick wall tube, has incomparable advantage over other techniques, can meet the requirements of users in the aspect of spiral steel pipe specifications more. Spiral steel pipe diameter and the size range to flexible, has great advantages, using their own set of more extensive user demand, popularization and promotion is the spiral steel pipe can be.
