Do you know the difference between Ductile Iron Pipe and PE pipe? Today, professional Ductile Iron Pipe Fittings Supplier will tell you the difference.
Ductile iron pipe is mainly called centrifugal Ductile Iron Pipe. It has the essence of iron, the performance of steel, excellent anti-corrosion performance, good ductility, good sealing effect and easy installation. It is mainly used for water supply, gas transmission and transportation of municipal and industrial and mining enterprises. Oil, etc. Compared with PE pipe, from the installation time, the spheroidal tube is easier and faster to install than the PE pipe, and the internal and external bearing pressure is better after installation; from the perspective of airtightness and corrosion resistance, the airtightness of the spheroidal pipe after installation is better. Corrosion resistance can be improved by various anti-corrosion methods; from the hydraulic performance point of view, the size of the spheroidal tube generally refers to the inner diameter, and the PE tube specification generally refers to the outer diameter. Because of the same specifications, the spheroidal tube can achieve greater runoff; In terms of comprehensive installation and maintenance cost, the spheroidal tube has a more superior cost performance. The main components of Restrained Joint Ductile Iron Pipe are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Zinc spray on the inner wall, anticorrosive materials for cement mortar, etc.
Advantages of Tyton Joint Ductile Iron Pipe: In medium and low pressure pipe network, ductile iron pipe has safe and reliable operation, low damage rate, convenient and quick construction and maintenance, excellent anti-corrosion performance, etc. Disadvantages of ductile iron pipe: the connection of ductile iron pipe is subject to human factors such as The operation level and responsibility have a great influence, and the construction is not as convenient as the PE pipe. The advantages of the PE pipe: the PE pipe has good corrosion resistance, and its anti-inorganic property is much stronger than the metal pipe, and does not need anti-corrosion when buried. Easy to construct. Small-diameter PE pipes are superior to steel pipes and Self-anchored Ductile Iron Pipe in performance-price ratio. PE pipes have disadvantages: organic solvents such as benzene, gasoline, and carbon tetrachloride have certain effects on polyethylene. If the organic solvent penetrates into the polyethylene, swelling occurs, the physical properties of the organic solvent are lowered, and the pressure resistance and temperature change resistance are inferior.
