Designed for City Water Networks
The Municipal Water Supply Pipeline Repair Clamp is our product for city water network maintenance. City water pipes are the lifeblood of urban areas. Leaks must be fixed fast to reduce water loss and customer complaints. Our clamp is designed for the specific conditions of city networks.
City networks use many pipe materials. Ductile iron, PE, and steel pipes are all common. Our clamp works on all of them. City network pipe sizes are mostly DN100 to DN300. We have the most complete size range in this category. Repairs often happen in narrow valve pits or road excavation pits. Our clamp is compact and easy to handle in tight spaces. The gasket creates multiple sealing bands for reliable sealing under both pressure and no-pressure conditions.
We have a skilled R&D and production team. Our factory is 3,500 square meters. Our annual sales exceed 80 million RMB. Our products are used by water groups in many provincial capitals. We hold ISO 9001 certification. Our products are tested by the Shanghai Institute of Quality Inspection.
