Stone pipe industry specializes in the production and development of pipes and fittings such as PVC-U drainage pipes for construction, spiral silencer pipes, PVC flame-retardant electrical casings, PVC-C power cable sheaths, PPR hot and cold water pipes, PE double-wall corrugated pipes And sales companies...Click for details
PE double-wall corrugated pipe is a new type of light-weight pipe with polyethylene as raw material and processed by extrusion and special molding processes. The inner wall is smooth and the outer wall is a closed corrugated type...Learn more+
PVC-C cable bushings are generally used in telecommunications, power engineering, transportation, urban construction and other fields. PVC-C cable sleeve has high temperature resistance...Learn more+
Advanced production line
Annual production capacity
Strong resistance to external pressure: The outer wall is a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the resistance of the pipe to soil load. Low project cost: Under the condition of equal load, PE double-wall corrugated pipe only needs thin and light pipe wall to meet the requirements. Compared with solid-wall pipes of the same material and specifications, it can save about half of the raw materials.Learn more
PVC-C cable bushing is made of (PVC-C) resin as the main material, added with necessary processing aids, and molded after extrusion. It is an improved power sheathing material with special physical properties. It is mainly suitable for The laying of power cables plays a guiding and protective role. The pipes are connected by flared sockets, which is convenient for installation and construction, with low project cost and short period. Its excellent physical and chemical properties are increasingly being valued and widely used in the power and communications industries.Learn more
