Q: How can corrosion protection of nodular cast iron pipes be buried?: No, the tube itself does. The joints or fittings should be reinforced with concrete

Q: What are the fittings of ductile iron pipes?: Selection of pipe fittings should first understand the way the pipe is connected, and the use of the pipe, and then select the relevant parts.The use of pipes is generally water supply and drainage.Ductile iron pipe joints generally have three ways of connection:1 socket connections (that is, W),2 flanged connections (that is, A type),3 clamp connection.

Q: How to improve the quality of cast iron pipe fittings: The speed of main machine, the amount of turnover and the speed of pipe die in controlling the cast iron pipe fittings1) in the casting, most of the cast iron pipe flowing from the chute flows forward, but there are still a small number of cast iron pipe, the molten iron flows backward, the cast iron pipe in the rear of the site, there is a "lead flow."".2) for cast iron pipe centrifuge host walk speed too slow (slow to advance flow speed) caused by the quality defects in cast iron pipe production requirements by improving the centrifuge speed, so as to shorten the time of casting.3) for cast iron pipe production sector due to the package of centrifuge turning package is too large (increasing the movement trend of advanced flow ") caused by the quality defects of cast iron pipe centrifuge operation requirements, in strict accordance with the process requirements to reduce the angular speed of fan turning package package.4) the quality defects caused by the high speed of the cast iron pipe fittings and the thinner lead flow of the molten iron require that the speed of the cast iron pipe die be lowered to the lower limit during the production of the cast iron pipe fittings.

Q: How much does it cost to install the W cast iron pipe?: If only the installation contract, according to caliber size, parts, construction site difficult price will vary, installation costs are generally about 15% of the total cost of protection. More detailed information, you can have a look

Q: Can ductile iron pipes be used for fire protection?: Galvanized steel pipes are not allowed to be used outside the ground. The so-called "strengthening corrosion prevention" is just a self deception!

Q: What are the fittings of the cast iron pipe for water supply and drainage?: There are many kinds of accessories, but I don't know the specific type you ask. For example, such as three pass, four pass, reducing valve, expansion joint, exhaust valve, elbow, short tube, sleeve, plug, plug, blind plate and so on.
