Q:How can the steel plastic composite pipe be connected with the cast iron pipe?
The clamp hoop is a connecting device for connecting pipe fittings, valves and pipe fittings with grooves. Used in the fast joint between the role of tightening, the general two joints with gaskets, rubber, and silicone, ptfe.
Q:What is ductile iron pipe?
Ductile cast iron is defined using the above number 18 by adding nodulizer, after centrifugal ductile cast iron machine centrifugal cast pipe, ductile iron pipe (called [span]Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
Q:What's the difference between ductile iron pipe and cast iron pipe?
We have to correct now basically all socket ductile iron pipes, because the socket type with a rubber ring, plus a ductile material, buried beneath it when the bearing has a certain flexibility, not because of the deformation and leakage phenomenon. To be used, not Unicom cast iron pipe socket, connection is used similar to the stainless steel hoop hoop sleeve closed.
Q:How long does the cast iron pipe of indoor direct buried sewage need to be examined?
Cast iron pipe, cast cast pipe. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. According to the interface form, it is divided into flexible interface, flange interface, self anchored interface, rigid interface and so on.
Q:What is the ductile cast iron pipe
Have not heard of the nodular cast iron pipe pipe, ductile iron may be a tube or a certain short tube is referred to as excellent grade.
Q:How can the ductile iron pipe be welded?
Welding cast iron is mainly in three aspects: carbon control, stress elimination, structural adjustment. You can choose better welding materials, such as WE777 and other imported welding materials. Crack resistance is very good. In addition, the sewing process can be adopted in the structure to increase the stability of the welding effect. You can learn more about WE777 welding applications.
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:What's the function of the cement mortar lining of ductile iron pipes?
In brief, the cement mortar lining system has the following advantages:1. provide active protection better than barrier coating2. meet both national and international standards for contact with potable water3. can be used in the strict requirements of the occasion4. strong and shock resistant5. suitable for a wide range of applications6. easy to repair7. over 100 years of service life
Q:Ductile iron pipe length is generally much
The water-cooled metal ductile iron pipe has a single length of 6 meters, and the current mainstream ductile tubes are water-cooled metal ductile iron pipes.
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.
