Q:Do ductile iron pipes have inner enamel?
For fire water and living water supply, low requirement is lined with cement mortar, some high can be lined with epoxy resin, epoxy ceramic lining, as well as cement mortar lining epoxy sealing layer (compromise is the price of blame).
Q:How to correctly measure ductile iron pipe
This need to find the right tools, Michi, caliper, amount to ductile pipe and pipe fittings and pipe fittings of the outer diameter, inner diameter, length and wall thickness were measured, eleven.
Q:How can the ductile iron pipe be tested?
Good command of pipe connection must be by hand when a pressure test, must be clear, on the back, pier, interface division, each part of the exhaust valve, must be responsible, then carefully inspected and clear and uniform pressure test.
Q:There are several forms of flexible interfaces for Spigot Cast Iron Pipes
Japan's Kubota ductile mechanical interface, in recent years has been introduced to China. As in the Beijing water pipeline construction from the Miyun reservoir to the Huairou reservoir, the use of a large number of nodular type DN2600mmK mechanical interface of cast iron pipe.The mechanical interface of ductile iron pipe is divided into A and K. The tubes and fittings are made of ductile iron, straight pipes, screws, bolts and rubber rings.The mechanical interface has good sealing performance. When the water pressure reaches 2MPa in the test, there is no leakage. The axial displacement and the angle of folding all reach a high level, but the cost is higher.
Q:What is cast iron pipe?
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. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated.
Q:Advantages and disadvantages of ductile iron pipes?
The ductile iron pipe has a single length of 6 meters and a large wall thickness. The cast iron tube has a single branch length of 3 meters and a thinner wall thickness.
Q:What does ductile iron pipe "ND200" mean?
The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.
Q:How can the ductile iron pipe be welded?
If the hole on the ductile iron pipe, you can use special hoop lined flexible rubber ring, rubber ring and pipe wall coating with rubber ring, glue to be fixed.
Q:Why does the cast iron pipe always run off when testing?
If the pipe is exposed for pressure test, you must add a pier, or else the fittings fly out. You are not surprised. At the same time, the pressure test before the ink tube to make full immersion bubble discharge clean, or a big easy gas pressure pipe explosion.
Q:Will the quality of ductile iron shrink?
This is a ductile iron is prone to problems, manhole covers, large flat pieces, you have to see clearly, and some appear to be concave, not shrink, it may be caused by large gas emissions, not out
