Established in 1998, China Guanda Hose Technology Co., Ltd. is a professional ductile iron pipe manufacturer and wholesaler of hoses and tubes. Our annually capacity of various kinds of hoses is more than 5,000,000 meters. Our customized ductile iron pipes products are applied in industrial equipment, hotels, villas, toilets, and kitchens. They are widely used in the field of aerospace, metallurgy, petrol-chemical, machinery, architecture, shipping, vacuum, power and light industries.

Modern ductile iron pipe has evolved through industry research, field experience, tight quality control and contemporary production techniques into the efficient product it is today. The people at Pacific States Cast Iron Pipe Company are dedicated to the production of the finest quality ductile iron pipe on the market.All ductile iron pipe has a slight taper due to the manufacturing process. If the pipe is not marked for field cutting then the diameter of the pipe should be checked prior to cutting. This can be done with an OD Tape or by using an MJ follower to check the diameter of the pipe. No pipe should be cut within 24 inches of the bell face.

Frazer are closely associated with Saint-Gobain Pipelines, the UK's largest supplier of Ductile Iron Water Pipe systems for both potable and waste water. Thousands of kilometres of Ductile Iron Mains are laid in the UK every year. In conjunction with our supply partner, SGPL, we are constantly looking to develop new products that ensure we can offer our customers the longest possible service life. The mechanical properties of Ductile Iron, combined with internal lining and external coating systems, ensure that Ductile Iron Mains provide assured long term performance.
The qualified cast ductile iron pipe is put into an annealing furnace to attain the required metallographic structure of ductile iron. The molten iron sets into a ductile iron pipe and cooled down by water then extracting from molds according to set time strictly.
