Q:If the ductile iron pipe is broken, can we use rush repair?
PE pipe repair section, as the name suggests, is a kind of used to repair the pipeline accessories. At present, the specifications of the repair section are: Phi 90, Phi 110, Phi 125, Phi 160, Phi 200, Phi 225, Phi 250, Phi 315 these specifications.
Q:What material is the cutting tool for ductile iron?
They are all hard alloy materials, all of which are CVD coatings, but the products produced by different manufacturers will be very different.
Q:Why is the cast iron tube lined with cement? Under what circumstances are ductile iron pipes lined with cement, and under what circumstances do not have to be lined with cement?
Cement lining to protect water quality, reduce loss, improve the service life of the pipeline ductile, ductile iron pipes are generally lined, which the en545 standard specifies the quality of what kind of what kind of cement.
Q:How can 4 inch ductile iron pipe be connected with 2 inch galvanized pipe?
The general electric welded steel pipe for clarinet.
Q:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
(4) HDPE pipes do not need corrosion protection. If the water supply pipeline is made of ductile iron pipe, the inner and outer walls of the ductile iron pipe shall be treated with corrosion protection.(5) the normal service life of the ductile iron pipe is 20~25 years after the pipe is treated by inner and outer walls. The HDPE tube has no corrosion, and the normal service life is 50 years.
Q:Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?
The situation in use abroad seems. It is considered that the corrosion of the inner wall of the centrifugal centrifugal ductile iron pipe and the rupture of the pipe are easy to occur when the content of chloride ion exceeds 5O0PPm in the pipe laying environment. This is mainly because, because the cement paste protection layer is the late spraying construction, it is not good to combine with the prefabricated core tube. It often causes water or moisture to seep in and causes oxidation and corrosion of the prestressing steel bars, resulting in fracture. The adhesive interface between cement mortar and centrifugally cast iron pipe is not reasonable. Because of the water absorption of cement, when the water enters the pipe, it is easy to destroy the interface and corroded the inner wall of the centrifugally cast iron pipe. Because it is a brittle material, it is easy to cause sudden accidents.
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
600-3 is pearlite + a small amount of ferrite matrix ductile iron. Pearlite edge region. 10%, center. 70600-3. Two sets of numbers indicating the grades and mechanical properties of nodular cast iron. The former represents the minimum tensile strength
Q:How do we handle the leaking of the ductile iron pipe?
A hoop is a component that holds or ties another material with one material. It belongs to the fastener. The hoop holding device is composed of a hoop plate, a wing plate, a tension tie plate, a bolt and an inner liner. There are many kinds of hoop, hoop cable, wire rod hoop, hoop cable, wire hoop, stainless steel hoop are commonly used.
Q:What new technologies are there for the installation of ductile iron pipes?
Because the new flexible interface mechanism of cast iron drainage pipe pipe in the development of China's relatively short history, compared with other drainage pipes, people know little of the present, with some experience of the author in the construction, the application of the performance, characteristics and engineering, to do some simple introduction.
Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Heavy thermal and mechanical shock, high temperature or low temperature, corrosion resistance and dimensional stability. To meet these changes in use conditions, ductile iron is available in many grades, providing a wide range of mechanical and physical properties.
