PU Ductile Iron Pipe
PU Ductile Iron Pipe is ductile iron pipe with a polyurethane coating, polyurethane coating is made of bi-component polyurethane materials to a scale, and not only does it serve as the inner-lining material of nodular castiron pipe, but as related outer errosion resistant coating. Polyurethane coating has many advantages such as wonderful abrasive resistance, excellent corrosion resistance, non-permeation, smmoth surface, small resistance coeffecient, few volatile organic compound,remarkable environmental protection property, ect. Some polyurethane coatings with a thickness of 900μm,are mainly applied to transportingcorrosive mediums or the mediums with high sanitary condition, including soft water, desalination seawater, municipal wastewater, industrial wastewater, and others; and some with thickness above 700μm are mainly applied to the soil environment with strong corrosivity such as the soil polluted by industrial wastewater or with low specific resistance.
Ductile iron pipes for sewerage application:
Product standard: BS EN598:2002
Quality checks at every stage of manufacturing:
1) Strict selection of raw material is an indispensable requirement to produce quality ductile iron pipes and fittings.
2) We produces liquid metal suited to manufacture ductile iron pipes. The liquid metal is further processed in induction furnaces. It is then treated with magnesium for modularization and transferred to the centrifugal spun casting machines.
3) The pipes are heat treated, zinc coated, hydrostatically tested, tested, cement mortar lined and finished with a layer of bitumen coating.
4) The in process inspection and quality control at all points during the production cycle is strictly maintained and documented as ISO9001 quality systems.
Packing: bundled with steel belts or in bulk
Shipment: in bulk or container
Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water and sewer lines. Ductile cast iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipes made from other materials like PVC, concrete, polyethylene or steel. Ductile Iron Pipe is the most widely-used pipeline product in water supply and water drain/sewage projects.
There are lots of qualified managers and technicians, and a well-trained team of after-sales service, which provides all services of manufacture, package, transportation and installation. We are looking forward to cooperating with friends from abroad and home creating a brighter future.
