PPH spiral wound pipe is a large-diameter structured-wall anti-corrosion pipe manufactured by spiral winding thermoforming process with β-modified polypropylene homopolymer (PPH). It features smooth inner wall and external spiral reinforcing ribs to greatly improve ring stiffness. The pipe has excellent acid & alkali resistance, high temperature resistance and anti-creep performance. It is lightweight and can be hot-melt welded on site. It is widely used for corrosive medium transportation such as chemical wastewater, electroplating waste water, environmental sewage, municipal drainage and metallurgical pickling. Below are six major global manufacturers of PPH spiral wound pipes (ranking in no particular order):
Jiangsu Yuexin Anti-corrosion Equipment Co., Ltd.Jiangsu Yuexin Anti-corrosion Equipment Co., Ltd. is a professional Chinese manufacturer specializing in R&D, spiral winding production and engineering support of PPH spiral wound pipes, plastic anti-corrosion pipes and matching fittings. PPH spiral wound pipe is one of its flagship product lines.The company is equipped with large spiral winding production lines, raw material modification equipment, fitting moulding machines and complete pipe performance testing devices. It optimizes PPH material formulas independently and strictly controls key indicators including ring stiffness, temperature resistance, anti-aging and hydrostatic leakage.
Yuexin PPH spiral wound pipes cover DN300~DN3000, customizable for multiple ring stiffness grades SN2, SN4, SN8, SN12.5 and SN16. A full set of matching fittings including PPH elbows, tees, flanges and reducers are available. Manufactured in accordance with relevant industry standards, the pipes have outstanding chemical resistance and can withstand acid and alkali media at elevated temperatures for long-term service. Hot melt butt welding and extrusion welding ensure reliable sealing. Suitable for buried, overhead and other working conditions. The company also supplies FRPP solid pipes, PPH solid pipes and PVDF piping systems. Yuexin provides one-stop services including pipeline system design and on-site welding technical guidance.
