The raw materials used for the FRP, PVC/FRP and PP/FRP tower equipment manufactured by our company are from domestic and foreign formal enterprises that have passed the IS9001 quality system certification and are included in our company as qualified subcontractors.

　　The design of the tower equipment meets the requirements of different corrosive media by changing the material of the lining layer and internal parts or the type of resin and fiber; Through finite element analysis, changing the resin and fiber types of the structural layer and adjusting the paving method can meet the strength requirements under the corresponding temperature and pressure.

　　The production, inspection and acceptance of PVC and PP linings and internal parts strictly follow the HG20640-1997 "Plastic Equipment" standard, and the externally reinforced FRP strictly follows the JC/T587-1995 "Fiber Winding Reinforced Plastic Storage Tank" standard.
