Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
Determine the authentic M35 cobalt bit, which is about 65HRC in hardness. General workpiece hardness of about 45HRC or less of the problem.
Q:What pipe can be used to replace the cast iron pipe in the water supply? Thank you
You are mistaken in concept. The cast iron pipe is the sort of connection method. The ductile iron pipe is classified according to the material.
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: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:What are the lubricants for the installation of ductile iron pipes for tap water?
Lubricant used to reduce frictional resistance of friction pairs and to retard wear of lubricating medium.
Q:Nodular cast iron, heat treatment process and so on
White cast iron is one of the defects. Firstly, control of carbon equivalent, carbon equivalent is not too high. The second inoculation is reasonable, the step of determining whether carbon in cast iron with graphite precipitation. Ensure adding good inoculant humectant and sufficient time. Once again, the problem of cooling. The cooling can not be too fast, easy fast cooling to produce white tissue.
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Different installation methods, ductile iron pipes are common flexible sealing ring, slide into the connection; the main drainage pipe is W and B type, clamp connection and mechanical connection, the inner gasket ring.
Q:How do we handle the leaking of the ductile iron pipe?
In order to repair the defects of castings, the same or similar materials are usually adopted, and the materials with better performance or special requirements are used under special circumstances. Before welding, it is necessary to check the defects, determine the location, size and nature of the defects, and dig them out in accordance with the relevant measures, and then weld them again. Therefore, the preparation before welding must be in place.
Q:How many meters does the cast iron water supply pipe dn150,1 tons?
Reciprocating centrifuge hydraulic device, the pressure was 9.65 x 105Pa. the speed through the overflow valve, cable and cooling water hose is generally fixed on the centrifuge and the machine next to the post, the other end is connected to the shell, random moving together. The production standard of centrifuges is usually fixed. If we want to produce several specifications of pipes on a centrifuge, we need to replace the fan-shaped packages, the hot metal flow plants and the support roller racks.
Q:Ductile iron pipes lined with cement mortar in the water (living water, water in the 6.9-7.3) in the early pH, why pH increased? How to solve this problem?
1, because of the bone in mortar, such as silicate products, there will be silicification reaction, in addition, there is the reaction of limestone in lime.2, cement mortar lining cover coating, that is, spray some paint! Some questions four are unavoidable
