Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
Then, according to the soil characteristics, different slopes are calculated, and the width of the excavation is calculated according to the depth and slopeIf the soil is soft, high water content and easy to collapse, the excavation width will be wide, otherwise the slope will be steep and the excavation width will be narrow
Q:Ductile iron pipes perennial bubbles in the water will rot it
Water supply pipe is the first choice, with high cost performance. Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external pressure bearing better tightness and corrosion resistance; from the point of view, ductile pipe sealing better after installation, but also can improve the corrosion resistance through various anti-corrosion methods;
Q:What kind of valves are commonly used in ductile iron pipes?
You ask the ductile cast iron valves used on no special, because this interface in connection with the valve on the pipe flange is basically, as long as the flange of the valve should be can be used in milling pipe.
Q:How can the ductile iron pipe elbow be fixed?
The utility model relates to a groove connecting pipe which has the function of sealing and sealing, and mainly comprises three parts: a sealing rubber ring, a clamping band and a locking bolt. The inner rubber sealing ring is arranged on the outer side of the connecting pipe and is matched with the pre rolling groove, and then the outer ring is buckled on the rubber ring, and then can be fastened with two bolts. Because of the special sealing structure design of the rubber sealing ring and the clamp hoop, the groove connecting piece has good sealing property, and the sealing property is enhanced correspondingly with the increase of the fluid pressure in the pipe.
Q:Can ductile iron pipes be made into clear tubes?
Of course, the cast iron pipe is suitable for being buried in the ground because of its corrosion resistance, rust resistance and non deformation.
Q:Usage of ductile iron pipe expander
Usage of ductile iron pipe expander:1, the expansion device should check its type, specification and piping configuration before installation, must comply with the design requirements.2, the expansion of the inner sleeve should be noted that the direction of the inner sleeve is consistent with the direction of the medium flow. The hinge rotation plane of the hinge type telescopic device should be consistent with the displacement rotation plane.3, the need for "cold tight" expansion device, pre deformation of the auxiliary components should be installed in the pipeline before they can be removed.4, it is strictly prohibited to use telescopic deformation method to adjust the installation of the pipe, so as not to affect the normal function of the telescopic device, reduce the service life and increase the piping, equipment and supporting components of the load.5 、 during installation, welding slag is not allowed to splash to the surface of wave shell, and the wave shell is not allowed to suffer other mechanical damage.6, pipe installation is completed, should be removed as soon as the wave expansion device used for installation and transportation of yellow auxiliary positioning components and fasteners, and according to the design requirements will be transferred to the specified position limiting device, the pipe system has the ability to compensate fully in the environmental conditions.
Q:The design uses water supply ductile iron pipe, PE corrosion protection pipe, HDPE pipe, please ask that good? What's the price of the two?
PE pipe is hot melt connection (with thick wall smooth type, don't use the wavy), has the advantages of convenient connection, not affected by terrain, but should pay attention to cold and rain when try not to do, otherwise easily lead to cracks or Water Leakage interface touch interface. The disadvantage is not pressure, heavy machinery on the flat, but the problem is not, as long as the water does not leak, do not need to redo. Also, PE price volatility is relatively large, the size of the price difference is relatively large, a few more runs to ask the price.
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:Can cast iron pipes not be used for domestic water supply and drainage?
Can be used for life drainage, I last year to do the public construction, 24 layers of life and drainage on the cast iron pipe.
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.
