Smooth Surface Di Pipe Class K9 Polyurethane Internal Coating For Sewerage

PU Ductile Iron Pipe Overview:
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, smooth 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.

The mechanical properties of pipes shall be as shown in the table,

Packing: bundled with steel belts or in bulk
Shipment: in bulk or container

 
Usage:
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.
