Q:Can ductile iron pipes be made of flexible waterproof sleeves?
Usually, a bushing is used to make a pool. It is the conduit to the sink. However, the common casing is difficult to seal so that there is water leakage between the casing and the pipe and water leakage between the casing and the wall. Only the waterproof sleeve can solve the water leakage between the casing and the wall, but it can not solve the seal between the casing and the pipe, and the flexible waterproof bushing can solve two problems.
Q:Advantages and disadvantages of ductile iron pipes?
Ductile iron pipes are mainly heated and annealed by intermediate frequency furnace, and then made as lining cement. The cast iron pipe is not made of lining cement.
Q:Which is good for water polo cast iron pipe steel pipe?
Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;
Q:Is the spigot and socket connection of the ductile iron tube reversed?
The tube is heated, in forming model, and the tube is arranged in the pipe drawing die; under the pressure of the tube is radially compressed, in radial compression in the direction of flow and the formation of metal pipe to pipe in the drawing die.
Q:Water supply pipe is ductile iron, then it's fittings and valves and other parts must be ductile iron?
Valve parts and materials do not require the same pipe material, as long as it can meet the use requirements and cost-effective.
Q:How many degrees can the ductile iron pipe be each?
In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%.
Q:What is the difference between a cast iron pipe and a ductile iron pipe?
The ball compressive strength of ductile iron pipe is much higher than that of cast iron pipes, buried in the ground, the car is not easy to be crushed.
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:How does the white iron appear in the case of ductile iron?
If it is to solve the white cast, the casting can be annealed.To prevent a chill in the casting, it is important to know your entire casting process to find the cause and the solution.
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
