Q:The difference between ductile iron pipe and UPVC drain pipe
UPVC tube or rigid polyvinyl chloride pipe, U-PVC pipe, is a kind of strong corrosion resistance, acid and alkali salt oil medium erosion, light quality, has certain mechanical strength, good hydraulic conditions, convenient installation, but easy to aging, high temperature resistant, but can not withstand the impact, applied to the domestic water system, DN50 pipe connection DN65, using a ring connected with the above.
Q:Does the cast iron pipe need separate corrosion protection?
No, the inner and outer corrosion protection of the tube has been done.
Q:What is a graphite cast iron pipe?
There is a graphite tube, but there is no graphite cast iron (if not ductile iron)
Q:Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?
Poor hydraulic performance and high energy consumption. The roughness coefficient of the prestressed reinforced concrete pipe is between 0.013 - 0.014, so that the pipeline resistance of the pipeline with the same pipe diameter is higher than that of the same water content. Because of its high roughness, after a period of use, the pipeline will be blocked by bacteria, shellfish breeding and reproduction. As the service life increases, the inner diameter of the pipe will gradually shrink and the resistance will increase.
Q:Ductile iron gears are generally treated without heat treatment
Certainly. At the very least, the casting must be annealed and other heat treatment according to the requirement of use
Q:What are the interface forms of ductile iron pipes? The best drawings are available. Thank you
Because of this interface and the corresponding T sealing aprons can withstand greater deflection angle and greater tolerances, especially suitable for unstable formations and corners.
Q:The design uses water supply ductile iron pipe, PE corrosion protection pipe, HDPE pipe, please ask that good? What's the price of the two?
Now the mainstream is PE pipe, ductile iron pipe has been going out.
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Different appearance, ductile iron pipe single length of 6 meters, large wall thickness; mechanism cast iron pipe single length of 3 meters, the wall thickness is thin.
Q:What is the wall thickness of K10 grade dn=400 ductile iron pipe?
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc.. Water supply pipe is the first choice, with high cost performance. Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external pressure bearing better tightness and corrosion resistance; from the point of view, ductile pipe sealing better after installation, but also can improve the corrosion resistance of corrosion protection through a variety of means; from the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
Q:Will the quality of ductile iron shrink?
Fool you. It is normal that the surface shrinks and goes down, but it can not be said to be good.
