Q:What are the advantages of cast iron pipes?
The ductile iron pipe with flexible joint construction, convenient operation, can improve the efficiency of construction, improve the construction conditions, reduce the construction cost, and most of the rubber ring connection interface, simple operation, can shorten the construction period, reduce the construction cost.
Q:How can the ductile iron pipe be tested?
Pipe in water pressure test, step by step step by step step up, and each time the boost value is 0.2 MPa, in each time after the boost, the heart must be determined after the voltage regulator can continue to step up
Q:Is the water cast iron pipe 100% for hydrostatic test?
After the site installation, according to the standard to test pressure, but a lot of construction units are not pressure test
Q:What quota can be used for the installation of DN300 ductile iron pipes?
Moreover, the ball tube is generally 5.5 meters long or 6 meters, if the length of the bridge is too long, to use the casing, the casing must also be fixed, 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:Ductile iron pipe in the direction of it?
The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
Q:Ductile cast iron can replace copper sleeve
Under dry friction conditions, we design a pre - formed synovial membrane on the surface of the bearing to ensure that the solid lubricant is transferred to the dual parts in the shortest possible time, and an effective solid lubricant film is formed
Q:How can the ductile iron pipes be treated with corrosion protection?
Bituminous paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying
Q:Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa
To your selected fire pump highest lift 1.5 times to suppress, generally not more than 1.6MPa, if the use of ductile iron pipe, test pressure according to 2MPa to suppress.
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.
