Dual laminate pipe is a solution to all corrosion problems. Thermoplastic material used for liner:PP,PPH,PVC,PVDF,etc. Bonding strength is a key index in inspecting dual laminate pipe. We are the first one in China to develop a unique mechanical bonding technique in dual laminate pipe thus make the piping system achieve the best bonding property to the highest limit which guarantee all indexes of bonding properties between liner material and reinforced layer reach to or above the Industrial standard that customers provided.
