Achieving the perfect lining for all types of pipes! SZ Method
Our diverse pipe lining technology provides optimal solutions tailored to various customer needs. The "SZ method" involves pulling an SZ liner into the sewer pipe using a manhole, expanding and heating the liner with air and steam to form a standalone pipe within the existing pipe. Even though SZ pipes are thin, they possess standalone pipe strength equivalent to or greater than that of rigid PVC pipes used for sewage. Furthermore, they excel in durability, oil resistance, and acid resistance, with a lifespan that is virtually permanent. 【Features】 ■ Forms a robust FRP pipe (standalone pipe) within the existing pipe ■ Has standalone pipe strength equivalent to or greater than that of rigid PVC pipes used for sewage ■ Flow capacity equal to or greater than that of new pipes ■ Excellent durability and chemical resistance *For more details, please refer to the PDF document or feel free to contact us.
