Q:Is the crankshaft material forged or ductile iron?
Nodular cast iron, cast iron, forged steel crankshaft are used in the three. There are 3 kinds of axes in our company
Q:How can the old water pipe ductile iron pipe be opened with three flanges?
Cast iron pipe is not good then did not take the treatment is not good in the local search do you master plumbing to the scene to see the actual situation, some teachers have you unexpected strain interpretation way.
Q:Ductile iron pipe in the direction of it?
The use of cast iron by adding more than 18 nodularizer, 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..
Q:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
Is it better to use precoated sand, but only a little higher cost?.
Q:Some questions about the bearing capacity of nodular cast iron pipes!
The pipe diameter is D, the tube thickness is T, and the internal bearing pressure P is related to the yield limit [S] of the pipe:PD=2T[S]Or [S]=PD/ (2T)If the P=3MPa, D=300mm and T=6 mm are substituted, the pipe yield limit should be given[S]=3*300/ (2*6) = 75 MPaI think the ductile iron pipe's yield limit should be greater than this value. Factory production should be all right. Only ductile iron pipe production, low product specifications, prices are higher.
Q:How many degrees can the ductile iron pipe be each?
In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%.
Q:Can ductile iron pipes be made of flexible waterproof sleeves?
Flexible waterproof casing is suitable for pipeline through the wall in vibration or by strict waterproof requirements of the structures of hardware fittings, general production enterprises according to the Construction Science Research Institute developed S312, 02S404 standard atlas manufacturing. The wall of flexible waterproof casing wall, in case of non concrete should be replaced by concrete walls, and a casing must be solidified on the wall; flexible waterproof casing application widely used in construction, chemical industry, iron and steel, tap water, sewage treatment and other units.
Q:Usage of ductile iron pipe expander
Ductile iron expansion is mainly provided with large flexible, easy installation, the product main material for nodular cast iron, nodular cast iron is mainly through spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than the strength of carbon steel. The material mainly has high strength of plasticity and toughness, and its development at home and abroad is very fast, the output has exceeded cast steel and malleable cast iron, become second only to gray cast iron casting alloy material. Spheroidal graphite is obtained by spheroidizing and inoculation of nodular cast iron. It can effectively improve the mechanical properties of cast iron, especially improve the plasticity and toughness, so as to obtain higher strength than carbon steel.
Q:What is a slide in type T flexible interface?
There are many kinds of cast iron pipe interface. The commonly used interfaces include sliding type (T type) flexible interface, mechanical type (K type) flexible interface, mechanical type (NII type, SII type) flexible interface, flange type interface and special interfaceSliding type (T type) flexible interfaceSlide type (T type) flexible interface as shown below. The ductile interface is widely used in the DN I000mm following the cast iron pipe, has the advantages of simple structure, convenient installation, good sealing characteristics. In the socket structure considering the location of the rubber ring and the deflection angle, this interface can adapt to deformation a certain foundation, has certain anti vibration ability, at the same time using the deflection angle of the long distance pipeline to achieve steering.
Q:Is there any cast iron pipe used in the fire hose?
I do not know, are generally seamless steel pipe or spiral pipe, straight seam pipe.
