Ductile iron pipe and high resistance to internal pressure and corrosion resistant, full of strength and toughness. High impact strength, mechanical joints flexible and scalable, easy fitting construction for normal soil conditions. Do not need to make a special sand tube base. and can be used backfill soil excavated ductile iron pipe, ductile iron pipe fittings variety DN250, original elbow, tee at fixed stations need to hit the cement protection. has been newly developed slip off the elbow and tee ductile iron pipes factory 1. embalmed asphalt paint coating asphalt paint coated cast iron pipes are pipes for transporting gas. Before painting the pipe by warming can improve paint adhesion of asphalt, and accelerate drying. 2. The cement mortar lining + special anti-corrosion coating such measures are applicable to convey sewage pipes DN300 ductile iron pipe, can improve the corrosion resistance lining. 3. coal tar epoxy coating of coal tar epoxy coating both for the gas pipeline, but also for sewers. It is a two-component coating which has a high adhesion and a very smooth surface 4. The ceramic epoxy lined ceramic epoxy lining applicable to sewage pipes and gas pipes, but due to the manufacturing process is difficult high cost DN400 ductile iron pipe, so there are some limitations on use. Ceramic epoxy lined with high adhesion and finish is an excellent anti-corrosion coating. 5. aluminate cement coating or sulfate cement coating these two special cement coatings are suitable for use in the sewers of ductile iron pipe corrosion, improve the ability to resist erosion acid wastewater constituents. 6. The polyurethane coating is an environmentally friendly to adapt to the needs and developed a new type of green special coating, good wear resistance and corrosion resistance.
