Qingdao Huashida Machinery Co., Ltd. has strong technical advantages and rich experience in equipment production. Now, the fourth generation of large caliber hollow wall winding pipe machinery has been developed .
Huashida large caliber hollow wall winding pipe machinery has many advantages:
Ring stiffness is high; pipe wall performance is uniform , and there is no weak link; welding between strip and strip with the same material (HDPE fusion is excellent), and after rolling cooling, the weld seam is uniform and firm, without leakage; good corrosion resistance, long service life, special-shaped steel strip after anti-corrosion treatment is completely buried in HDPE strip, steel strip will not corrode, pipeline life is over 50 years .
