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:How can the three pipes of ductile iron leak?
When the pipe connection of the three water leakage, first of all to see whether it is to do the pipe three links of the manufacturers, pressure did not reach, if it is. It is only the replacement, if not, with cast iron electrode welding, or socket connection half!
Q:How much is the installation of cast iron pipe drainage 1 meters?
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..
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:How many degrees can the ductile iron pipe be each?
Although ductile iron has a certain plasticity, it should not be bent in use
Q:Which is better, ductile iron pipe and spray plastic pipe?
Ductile iron pipe corrosion resistance, strength, it is said that the Ming Dynasty ordinary cast iron works now, and now has a new type of dedicated, can be used, construction becomes very convenient, ductile iron pipe has no effect on water quality. Plastic sprayed steel pipe is a new type of pipeline with higher price.
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Of different uses, ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanism cast iron pipes are mainly used in the city.
Q:How do we handle the leaking of the ductile iron pipe?
If it is installed in the pipeline, test pressure leakage, glue can be repaired and then welded, usually with hoop.
Q:How can stainless steel pipes and ductile iron pipes be joined?
The utility model can be connected with a wide range flange joint or a wide range flexible joint
Q:What is a slide in type T flexible interface?
There are many kinds of cast iron pipe interface. The commonly used interfaces include sliding type (T type) flexible interface, mechanical type (K type) flexible interface, mechanical type (NII type, SII type) flexible interface, flange type interface and special interfaceSliding type (T type) flexible interfaceSlide type (T type) flexible interface as shown below. The ductile interface is widely used in the DN I000mm following the cast iron pipe, has the advantages of simple structure, convenient installation, good sealing characteristics. In the socket structure considering the location of the rubber ring and the deflection angle, this interface can adapt to deformation a certain foundation, has certain anti vibration ability, at the same time using the deflection angle of the long distance pipeline to achieve steering.
