Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Of different uses, ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanism cast iron pipes are mainly used in the city.
Q:Comparison of ductile iron pipe and spiral steel pipe
Spiral welded pipe: inner wall smooth, welding connection, a small amount of pressure, need additional anti-corrosion
Q:Will nodular cast iron pipes rust?
Although the wall has a long flow of water, but oxygen scarce, compared with the outer wall is not easy to corrosion, but there is cement lining is necessary.
Q:What is cast iron pipe?
Divided into gray cast iron pipe and nodular cast iron pipe according to different material. According to the interface form, it is divided into flexible interface, flange interface, self anchored interface, rigid interface and so on. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated.
Q:What are the specifications for the installation of water ball iron pipes?
Ductile cast iron pipe is characterized by mild, high, thin wall, pressure resistance, impact resistance, corrosion resistance, seismic resistance and other properties. The flexible interface is used for the pipeline interface, and there is a certain elongation and deflection angle. The utility model has the advantages of the raw iron pipe and the steel pipe material, and avoids the defects of iron and steel.
Q:What are the interface forms of ductile iron pipes? The best drawings are available. Thank you
T interface type sealing ring is a self sealing rubber ring, when the pipe internal pressure increases, the contact pressure between the seal and the pipe increases, T interface can not only allow the deflection angle of the axial displacement, and convenient for installation. When the T type interface is installed, the sealing of the rubber ring can be ensured as long as the socket is simply loaded into the socket and the rubber ring is pressed tightly. This kind of interface has the advantages of reliable sealing, good seismic resistance and corrosion resistance, and it is a better interface.
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: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:What is cast iron pipe, specification for cast iron pipe?
According to the different casting methods, the labor intensity is divided into continuous cast iron pipes and centrifugal cast iron pipes, in which the centrifugal cast iron pipes are divided into two kinds: sand mould and metal mould. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. Rubber ring seals for flexible interfaces,
Q:Which is better, ductile iron pipe and spray plastic pipe?
Ductile cast iron: the use of more than 18 by adding nodulizer, 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.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
