Ductile iron pipe and steel pipe performance comparison:
Steel pipes can be divided into seamed steel pipes and seamless steel pipes. Sewage pipes are generally used in the middle of a water supply pipe. Compared with the ductile iron pipe, the steel pipe has the advantages of good toughness, large tensile strength, thin wall, high pressure resistance, long pipe length, and less interface. The biggest disadvantage is that the corrosion resistance is poor and the price is high. Therefore, in general, except for small diameter pipelines and special projects.
Liaocheng Hongfu Pipe Co., Ltd. is a professional sales ductile iron pipe, seamless steel pipe, high pressure boiler pipe, high pressure alloy pipe, square pipe manufacturers, to understand the latest ductile iron pipe prices, seamless steel pipe prices, high pressure boiler pipe prices on the advice .
Ductile iron pipe and prestressed reinforced concrete pipe performance comparison:
Ductile iron pipe and prestressed reinforced concrete pipe (applicable to large-diameter pipe, the maximum diameter has exceeded 2000), with the following characteristics:
(1) Save energy, the main material is sand, stone, can be drawn on the spot.
(2) Heavy weight, brittle texture, difficulty in cutting, and relatively large difficulty in construction.
(3) The working pressure is 2o% lower than the ductile tube and 40% is 0.15-0.25MPa.
(4) The maximum deflection angle is 1.5 degrees, and the ductile iron pipe is up to 3.0 degrees, so the pre-stressed reinforced concrete pipe has poor terrain adaptability.
