13 spiral steel pipe production lines+4 anti-corrosion and insulation lines, with an annual production capacity of 400000 tons, refusing intermediaries to profit from price differences
Holding API 5L-0640 logo usage authorization (covering PSL1/PSL2, up to X80), strictly implementing ISO9001 system.
Provide a complete set of customized services from bare pipes to 3LPE/FBE/epoxy coatings, and then to pipe end groove processing, reducing the hassle of outsourcing processing.
Ultraviolet (UV) resistance:To ensure that our MBBR media can maintain the best performance and longest life in various environments.
Chemical resistance: Through the use of chemical-resistant materials or coatings to enhance the chemical resistance of the media, suitable for the treatment of wastewater containing strong acids, alkalis or other corrosive chemicals.
Enhance biological adhesion: Through the surface modification technology or special materials, to improve the ability of microorganisms to adhere to the surface of the media, to accelerate the formation and stabilization of biofilm, to improve the efficiency of wastewater treatment.
Porous structure optimization: Through the optimization of the internal structure of the media design, increase the effective surface area, improve the oxygen transfer efficiency, while maintaining good fluidity and anti-clogging.
