Q:What is a graphite cast iron pipe?
Ordinary cast iron consists of gray cast iron and ductile iron, the difference is the carbon in cast iron (graphite) exist, graphite in gray cast iron is in the shape of flake, so the strength and toughness are poor; graphite in shape is spherical, with little on dissevered the matrix. So strong and toughness will be much better.
Q:DN300 what's the price of the ductile iron pipe / the weight and the price of one meter?
Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance.
Q:How can the cast iron pipe of the ductile iron pipe be repaired?
First of all, to see whether the manufacturers do elbow pressure did not reach, if it is. That can only be replaced, if not, with a cast iron electrode welding repair.By the way, ductile iron can only be welded and not welded.
Q:What is the DN400 installation charge for ductile iron pipes?
1. hourly wage or piece wage: refers to the hourly wage and work hours or the work done by the unit price to pay individual labor remuneration.2. prize: refers to the excess labor and increase revenue of remuneration paid to individuals. Such as saving prize, labor competition prize, etc..3. subsidy: refers to compensate workers special or extra labor and other special reasons for the subsidies paid to individuals, and in order to ensure that the impact of inflation on real wages paid to individual price subsidies. Such as mobile construction allowance, special area construction allowance, high temperature (cold) operation, temporary allowance, aerial allowance and so on.
Q:When the ductile iron pipe is pressed, the three links are always running out. What should be done?
This situation depends on whether the pipeline installation is in place and the apron installation is standard. If there are no other problems, it is recommended to play a cement pier, half a pack of three can be solved.
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:How can stainless steel pipes and ductile iron pipes be joined?
The ductile iron pipe is connected to the ball milling cast iron pipe by spigot and socket
Q:How can the three pipes of ductile iron leak?
The raw material used in RE can be installed in the thread, can also be used on the same thread AB, re install is also available, but it is hard to remove.
Q:Is the cast iron pipe buried in need of antiseptic treatment? What kind of anticorrosive materials are used?
It must be antiseptic. Usually hot asphalt brush painted two times, winding glass fiber cloth two road, cross construction.
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.
