Q:Can ductile iron be welded? Is weldability comparable to gray iron?
Suitable for the full range of cold welding welding, welding cast iron base material can almost all, and it is easy to achieve cast iron and carbon steel dissimilar metal welding, such as solving matrix fracture, crack, wear, hole filling defects after welding can be machined, many applications in the engine casing, cylinder head, casting machine, gear base the tooth of iron castings.
Q:Which direction should the spigot of the K9 ductile iron pipe be installed?
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 of corrosion protection through a variety of means; from the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
Q:Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?
From the centrifugal ductile cast iron pipe with cement production process to analysis, the most core pipe by centrifugal molding, concrete water cement ratio, the centrifugal force, the coarse aggregate to the outer wall of the pipe and the pipe inside; because of fine aggregate and water removal, strength and wear resistance variation. When the inner wall of the pipe by long-term washing and soaking water, and inner wall wear and erosion, as the roughness increases, head loss increases, you will need to increase the pump lift, and operation cost for power consumption increases, also greatly increased.
Q:What are the differences between cast iron pipes W and A?
Cast iron drainage pipe generally divided into three categories, namely W type socket cast iron pipes, cast iron pipes of A type, B type cast iron drainage pipe, the three pipes have good seismic performance, strong sealing performance, simple construction, convenient maintenance, reliable use, so it is also called the cast iron pipe for earthquake.
Q:Is the spigot and socket connection of the ductile iron tube reversed?
The whole process is formed by the radial compression of the pipe blank and the stretching process of the branch pipe. Different from the hydraulic bulging three, the metal of the three way joint pipe is compensated by the radial movement of the tube blank, so it is also called radial compensation process.
Q:Ductile iron pipe joint damage, water leakage, want to see the connection with other pipe fittings, how to operate?!
Sawing grinding head, increasing steel socket set
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:Ductile iron pipe is flexible pipe or rigid pipe
The flexible tube and you say should refer to the common steel pipe and seamless steel pipe, because the two are by the simple method according to the needs and the deformation, in other words, ductile iron is cast out without deformation.
Q:What is the difference between spheroidal graphite cast iron QT400-15 and QT400-15A? What does the A mean later?
The front is the material grade, and the back of the A should have special requirements.
Q:Why is the cast iron tube lined with cement? Under what circumstances are ductile iron pipes lined with cement, and under what circumstances do not have to be lined with cement?
Cement lining to protect water quality, reduce loss, improve the service life of the pipeline ductile, ductile iron pipes are generally lined, which the en545 standard specifies the quality of what kind of what kind of cement.
