Q:How much is the installation fee of the 400 largest ductile iron pipe?
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 through various anti-corrosion methods;
Q:How long does the cast iron pipe of indoor direct buried sewage need to be examined?
Indoor drainage of the majority of households are using cast iron pipe, if the distance from the sewage well is relatively close, and the above does not take the car, you can consider the U-PVC.
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 pipe joint leakage
After cleaning the pipe mouth, the cf-2000 high efficiency composite waterproof agent is used to seal it, and it will not leak.
Q:Advantages and disadvantages of ductile iron pipes?
Ductile iron pipes are commonly made of flexible sealing rings and slip through connections. The main mechanisms are W and B, clamps and mechanical connections, and inner gaskets.
Q:Classification of cast iron pipes
Continuous cast iron straight pipe:Continuous cast iron pipe, namely continuous casting gray cast iron pipe, suitable for water and gas pressure fluid delivery.
Q:Advantages and disadvantages of ductile iron pipes
The ductile iron pipe is widely used not only in foreign countries, and has also been in the country to promote the use of good, in many areas of our country, ductile iron pipe has been widely used in medium and small diameter water supply pipe; compare the performance of ductile iron pipe and steel pipe: steel pipe can be divided into seamed steel pipe and seamless in the water supply pipe, commonly used in welded tube. Compared with ductile iron pipes, the steel tube has the advantages of good toughness, high tensile strength, thin tube wall, high pressure resistance, long pipes and less interfaces. The biggest drawback is that the corrosion resistance is poor and the price is high. So, in general, except for small bore pipes and special projects (such as pipe jacking works);
Q:How can the ductile iron pipe elbow be fixed?
The utility model relates to a groove connecting pipe which has the function of sealing and sealing, and mainly comprises three parts: a sealing rubber ring, a clamping band and a locking bolt. The inner rubber sealing ring is arranged on the outer side of the connecting pipe and is matched with the pre rolling groove, and then the outer ring is buckled on the rubber ring, and then can be fastened with two bolts. Because of the special sealing structure design of the rubber sealing ring and the clamp hoop, the groove connecting piece has good sealing property, and the sealing property is enhanced correspondingly with the increase of the fluid pressure in the pipe.
Q:What is the acceptance of cast iron pipe material?
Specific acceptance, first of all in line with national standards, followed by the provisions of the contract, and then the project requirements. General contract and drawings will have the requirements and standards of pipe. I hope I can help you.
Q:Is the cast iron pipe buried in need of antiseptic treatment? What kind of anticorrosive materials are used?
Need general brush oil can.
