Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
Cutting method for cutting ductile iron pipes, in order to obtain neat kerf, we should start with a direction of play saw saw to end. If the requirement of the section is not high, the direction of sawing can be changed gradually to reduce the resistance and facilitate cutting in.
Q:What pipe can be used to replace the cast iron pipe in the water supply? Thank you
According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. 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:Can the underground cast iron pipes be connected with clamps to form buttress?
The hoop has the advantages of beautiful appearance, convenient operation, strong clamping force, good sealing performance, etc.. Mainly used for connecting and fastening vehicle, ship, diesel engine, gasoline engine, machine tools, fire, and other machinery and equipment, chemical equipment general nylon hose, plastic hose, hose cloth, water interface and seal etc..
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:Ductile iron pipe connection mode
Jack painted on the outer surface and rubber lubricant: lubricant evenly installed ring inner surface, outer surface coating in the socket to socket socket parts lubricant line all the brush in the socket.
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:What is the relationship between the direction of the spigot and the direction of the flow in the ductile iron pipe?
The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:Is there a kind of pipe called lined ductile iron pipe? Seeking manufacturers?
This is basically used as drainage, ie the launching system. The fittings they use are different. You can use specific Baidu search or check, Suzhou arhccom Pipe Industry Co. Ltd., which specializes in Jiangsu ductile plastic lined pipe, ductile iron pipe and fittings. You say there are many manufacturers, they specialize in doing your jade lining plastic ductile iron pipe (second line brand), the new lining plastic ductile iron pipe (brand). Hope to help you.
Q:Usage of ductile iron pipe expander
Spheroidal graphite iron expander, also known as cast iron telescopic device, is a new type of pipe connector.
Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?
Because of the high tempering stability of the nodular iron, the tempering temperature is 400-450 degrees, and the tempering time is 1 hours.
