Q:How long is the service life of the cast iron pipe, and the time of use of ductile iron pipes?
When it comes to the service life of nodular cast iron, its maintenance is essential for its long service life. Then, the focus of the maintenance of ductile iron pipe is to pay special attention to, will affect the long-term use of ductile iron pipes, stable operation of socket, row, etc., we should make efforts to these aspects of the mouth without debris. Make sure that the rubber ring of the ductile iron pipe has been smashed with a rubber hammer, and it is not twisted or twisted, and it is uniformly stuck in the slot. Ductile iron pipe in the maintenance process, because of the pneumatic tube axis is buried into the ground, so in the face of a tilt angle of the time, we must be careful, if the resistance is too large, will not force the excavation, in order to prevent the distortion of the rubber ring.
Q:How can the internal and external walls of ductile iron pipes be protected from corrosion?
Inner wall cement anticorrosive exterior wall asphalt anticorrosion
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
Q:Ductile iron pipe in the direction of it?
The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:Does the cast iron pipe need separate corrosion protection?
No, the inner and outer corrosion protection of the tube has been done.
Q:What is the minimum pipe diameter of cast iron pipe?
Cast iron pipe: cast pipe made of cast iron. 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.
Q:Deep well spiral iron pipe, or ductile iron tube?
Ductile weakness: ductile cast iron pipes connected by human factors such as the operation level of responsibility, influence, construction not convenient. The advantages of PE PE PE pipe has good corrosion resistance and its anti inorganic performance than that of the metal pipe is much stronger in the buried without corrosion, construction convenient. Small diameter PE pipe in the price performance ratio is better than that of steel and ductile iron.PE tube have disadvantages: benzene, gasoline, carbon tetrachloride and other organic solvents have certain effect on pe. If the organic solvent is infiltrated into the polyethylene, the swelling will occur, and its physical properties will be decreased. Its pressure resistance and temperature resistance are poor.
Q:How many meters does the cast iron water supply pipe dn150,1 tons?
Centrifugal ductile iron pipe water-cooled metal type centrifuge daira executed by.Dg100 mm following the closed mold mold jacket cooling, more than Dg150rnm with rain type cooling.
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
Grade high good, mechanical performance can reach or exceed the standard, the grade is not high, the performance can not be achieved
Q:Method for joining cast iron pipes
The connection between the pipe and the pipe adopts the form of socket type or flange disk interface. According to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with rubber ring, which allows a certain degree of corner and displacement, so it has good seismic resistance and tightness. It is easy and quick to install than rigid interface. It has little labor intensity according to the casting method.
