- Q:How can the ductile iron pipe be punched?
- Main points: manual hydraulic drilling machine and drilling machine, drilling machine is to rely on human features manually through the drill holes in the pipeline: the need for manpower and time, simple operation and economic benefits; characteristics of the hydraulic drilling machine is through the electric pump or gasoline pump driven drill holes: human, mechanical opening. The need for daily maintenance, high cost. General aperture 300mm can be done by hand drilling machine
- Q:How to inspect ductile iron pipe fittings?
- The quality of water supply pipe ductile is a topic worthy of discussion, how to judge the quality of the ductile iron pipe, ductile now on the market is all kinds of pipe, a name sand type ductile iron pipe, ductile water-cooling tube, K8 grade K9 grade ductile iron pipe, ductile iron pipe, also the brand is divided into ductile ductile pipe pipe, big brands, and some well-known manufacturers of producing ductile pipe
- Q:Could you tell me how to weld ductile iron parts and steel tubes?
- Disk or disk plug connection, it is best to use flange connection. First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld pipe. But note, because ductile iron pipe material is crisp, and the two connecting flange sealing surface is best all the plane, in order to prevent damage due to uneven iron flange.Material is different, ductile iron pipe is made of ductile iron, seamless steel pipe is made of structural steel. Such as No. 20 steel, No. 35 steel, 16Mn steel and so on. The two is the manufacturing process is also different, ductile iron pipe is generally sand casting molding; seamless steel pipe is made of billet through seamless steel tube mill hot rolling molding.
- Q:Connecting process of ductile iron pipe spigot and socket rubber ring
- The material is made of metal rubber. It is a kind of homogeneous elastic porous material. It not only has the elasticity of rubber, but also has excellent characteristics of metal, it can work at -150~800 centigrade temperature. At the same time, it can also bear pressure and within a certain range has dual functions of pressure and seal.
- Q:How can ductile iron pipes be connected to steel tubes?
- Disk or disk plug connection, it is best to use flange connection.
- Q:How much is the installation of a two degree elbow for ductile iron pipe fittings at 11.25 degrees?
- Ductile iron pipe, executive standard, GB/T13295-2008ISO2531/2008, national GB/T13295-91 standard, ISO2531-K9 class.
- Q:Comparison of C and K grades of ductile iron pipes
- C grade tube is the latest international standard for ductile iron pipes. The product standard is ISO2531:2009, which is compared with the original standard ISO2531:2003 class K pipe code. Pipe usage remains unchanged. But the new standard (C pipe) classification is based on the allowable work pressure grade of the pipe, while the original standard (grade K tube) is classified according to the pipe wall thickness grade.
- Q:What are the categories of ductile iron pipe fittings?
- But even if it is plastic and rotational, between the two in the process and the use of the effect also has the essential difference. Pipe fittings, usually coated with epoxy resin in ductile iron grooved pipe fittings. But this kind of pipe in the process without heat pipe trench because of rotational rotational adhesion as mature, its internal plastic heat pipe trench.
- Q:How can the ductile iron pipe be connected to the PE pipe?
- Other ways of connecting steel and plastic excessive, one end is PE, and the other end is iron pipe fittings, but not as reliable as flange pressure, different systems pipe connection, it is recommended to use flange connection.
- Q:Is the cast iron tube the same as the ductile iron pipe?
- According to its manufacturing methods can be divided into: sand, centrifugal pipe, straight pipe, continuous cast iron pipe and sand pipe.According to the material used, it can be divided into gray iron pipe, nodular cast iron pipe and high silicon iron pipe.
