Description

-Pipe end beveled ****5 degree with root face 1.6+/*0.8mm,
 
-Tolerance of Wall Thickness: thickness between 5mm and *5mm, +/*0.1T; thickness higher than *5mm, +/*1.5mm;
 
-With department of quality control, product, facilities, technical, purchase, safety department, and warehouse, general office, we mainly produce the spiral steel pipe. The annual output reaches **0,**0 tons.
 
-With Lincoln welding machine, we have advanced production technology and steady performance. Each pipe is detected by x-ray tests, hydrostatic tests and ultrasonic tests.
 
-The D***0 line uses the most advanced “Fly welding technology and equipment”. When we finish this project, the annual production of various spiral steel pipes will be more than **0,**0 tons
