- Q:Which is good for water polo cast iron pipe steel pipe?
- In summary, if the demand is not high, the use of stable environment, pressure and vibration is not a place recommend the use of ductile iron pipe; if is an important facility for high requirements or site conditions, abnormal conditions, vibration and impact may be relatively large, with ordinary seamless steel tube.
- Q:How can the connection of ductile iron pipe elbow be convenient for connecting?
- The groove connecting pipe consists of two categories of products: sealing function of pipe connections with rigid joint, flexible joint, mechanical three and groove flange; the pipe connections transition of elbow, three links, four links, different diameter pipe, blind plate etc..
- Q:What is the use of ductile iron?
- Manufacturer of automotive diesel engines are starting from the prolong engine life, particularly cautious about expressing selection of crankshaft material, when the isothermal bainitic ductile iron and high strength in order to increase the power to weight ratio, expand the turbocharger use influence design according to the material, equipped with exhaust turbocharger tube the temperature is increased to 500 to 70. C, in this condition, the oxidation and creep strength become important. Ductile iron, with good properties, is being used instead of gray iron for the exhaust pipe and will further use silicon aluminum alloy ductile iron as the temperature increases.
- Q:How can the ductile iron pipe depress the elbow so as to prevent it from being opened?
- The elbow is the pipe that changes the direction of the pipe. According to the angle, there are 45 degrees and 90 degrees, 180 degrees, three most commonly used, in addition, according to the project needs, including 60 degrees and other non normal angle elbow.
- Q:How much water seepage is allowed in the water pressure test for water hose DN300?
- Test method: metal composite pipe and water pipe system 10min observed in the test pressure, the pressure drop should be no more than 0.02MPa, and then reduced to working pressure check should be no leakage of plastic pipe; water supply system should be in the test pressure regulator 1H, pressure drop shall not exceed 0.05MPa, then stabilized at 1.15 times the working pressure of the state under 2h, the pressure drop shall not exceed 0.03MPa, and check each connection must not leak.
- Q:How do we handle the leaking of the ductile iron pipe?
- If it is installed in the pipeline, test pressure leakage, glue can be repaired and then welded, usually with hoop.
- Q:Which direction should the spigot of the K9 ductile iron pipe be installed?
- 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 of corrosion protection through a variety of means; from the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
- Q:Method for cutting cast iron pipe
- Depends on the material and the use of requirements. Ordinary gray iron, if the incision is not strict, such as water pipes. They are all sheared with hydraulic cutting machine, but the incision will not be very smooth. If it is ductile iron, and the incision requirements are high, it can only be used plasma cutting machine. General fittings, if not specifically required, shall not be cut by machining methods.
- Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
- Ductile iron is good, its tensile properties are destined to withstand low temperatures, gray cast iron is a little bit worse.
- Q:Maximum pipe diameter of ductile iron pipe
- Price even if it is not clear, you can consult the ball mill cast iron pipe manufacturers!
