Q:What does "K8" mean in ductile iron pipe grades?
In wall thickness, K is the standard for wall thickness. The smaller the figure, the thinner the wall thickness of the same specification.For example, the K7 wall thickness of K8 is less than K8, and the wall thickness of DN500 is less than K9
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:How can the ductile iron pipe depress the elbow so as to prevent it from being opened?
Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metals and plastics.
Q:DN300 what's the price of the ductile iron pipe / the weight and the price of one meter?
The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
The sewerage system uses ductile iron pipes. The premise should be pressure pipe drainage. It must be a special occasion, otherwise the cost will be high. In general, precast concrete pipes are recommended.
Q:What is the DN400 installation charge for ductile iron pipes?
1. hourly wage or piece wage: refers to the hourly wage and work hours or the work done by the unit price to pay individual labor remuneration.2. prize: refers to the excess labor and increase revenue of remuneration paid to individuals. Such as saving prize, labor competition prize, etc..3. subsidy: refers to compensate workers special or extra labor and other special reasons for the subsidies paid to individuals, and in order to ensure that the impact of inflation on real wages paid to individual price subsidies. Such as mobile construction allowance, special area construction allowance, high temperature (cold) operation, temporary allowance, aerial allowance and so on.
Q:What new technologies are there for the installation of ductile iron pipes?
Type W: type W tube in the same pipe with high strength, low noise, good fireproof performance, long service life, with the characteristics of flexibility and good seismic performance, but also has synchronous construction, utilization rate is high, easy to pipe, reducing the hydraulic test of pipeline clearing times, shorten the construction period to improve economic benefits. In addition, this type of interface with bolts in the lateral fastening, avoids the defects of socket flexible interface flange is easy to damage, close to the wall to the fixed bolt, has the advantages of simple operation, so in the selection of building drainage pipes and fittings, with strong competitiveness. In addition, because the length of W pipe is 3M, the number of intermediate joints is greatly reduced, and any length can be intercepted in accordance with the requirements, thereby greatly saving the pipe material, reducing consumption and cost. W type socket with stainless steel hoop rib clamp, lined with rubber ring flexible connection, seismic performance and good sealing performance, no leakage and allowed to swing in a certain range. Therefore, W tubes are widely used both at home and abroad.
Q:Is the fire hose capable of using rapid repair joints?
Installation joint. Insert the socket into the socket to coincide with the central axis of the pipe or pipe to be joined. Use a guide chain to tighten the pipe member until the pipe mouth enters between the two white lines.
Q:Method for cutting cast iron pipe
Generally cast iron pipe wall thickness, crisp texture, with traditional saw blade, saw blade cutting, very expensive cutting materials, and cutting accuracy is not high. Nowadays, the cutting tools and cutting machines on the market cut off these kinds of pipes, which are fast and cutting tools. Because the length of the pipe is not cut, the pipe can be continuously cut for a while after the equipment is loaded on the equipment. The worker can spare more time and can realize the operation of more than one machine, thus greatly improving the cutting efficiency. Rotary tool pipe cutting machine cutting cast iron pipe sawdust granular, easy chip removal, cutting section of vertical high, smooth surface without burr. The current equipment has been widely used in cast iron pipe cutting, especially iron pipe cutting, even cylinder car production.
Q:Does the cast iron pipe need separate corrosion protection?
No, the inner and outer corrosion protection of the tube has been done.
