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:Deep well spiral iron pipe, or ductile iron tube?
Ductile iron pipe is a kind of cast iron pipe. In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the cast iron pipes, ductile iron pipes and finished product libraries can be better improved, with the nature of iron and the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:How can the connection of ductile iron pipe elbow be convenient for connecting?
Ductile cast iron pipe in the groove pipe connection technology is also called the lathedog connection technology, has become the most liquid and gas pipeline connection technology, although this technology is later than foreign in domestic development time, but because of its advanced technology, domestic market quickly received. Since 1998, it has been developed and applied in just a few years. It has gradually replaced two traditional ways of pipe connection, such as flange and welding. Not only technically more mature, the market is generally recognized, but also by the national laws and regulations actively guide the policy. The application of grooved pipe connection technology makes the complex pipe connection procedure simple, fast and convenient. Took a big step forward in pipeline connection technology.
Q:What is the relationship between the direction of the spigot and the direction of the flow in the ductile iron pipe?
Use more than 18 casting molten iron, by adding the spheroidizing agent, through the centrifugal ductile iron machine high-speed centrifugal casting pipe
Q:How can the ductile iron pipes be treated with corrosion protection?
Cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.
Q:What are the differences between cast iron pipes W and A?
Type W: combination of both advantages of the connection type A interface has the advantages of high strength and convenient installation, because of the use of W type straight pipe and reduces the material cost and can be coupled with the design structure of the B type pipe is more compact than the A type pipe, saving installation space.
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:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Heavy thermal and mechanical shock, high temperature or low temperature, corrosion resistance and dimensional stability. To meet these changes in use conditions, ductile iron is available in many grades, providing a wide range of mechanical and physical properties.
Q:Ductile iron pipe, socket connection, pipe length, you can cut open it?
Yes, but the pipe that needs cutting is a cut off pipe with a scissors mark.
Q:Is the cast iron pipe buried in need of antiseptic treatment? What kind of anticorrosive materials are used?
It must be antiseptic. Usually hot asphalt brush painted two times, winding glass fiber cloth two road, cross construction.
