Product Description:

Ductile Iron Cast Pipe is without any defects compare with tradition casting tech, which has many advantages particularly as follow:

(1) High density. In the "vertical upward casting" process, the melt iron of centre liquid column in center crystallizer is continuously feeding for volume shrinkage caused by condensation tube at outer circumference , which lead to be free of shrinkage porosity.

(2) High purity. When melt iron pouring, the mixed impurities such as gas, dross, sand grain which are lighter than melt iron could be eliminated at furnace mouth, its impossible to enter into the crystallizer through the channel, so the melt iron into the crystallizer is very pure.

(3) Strength with toughness. The cooling speed provided by continuous crystallizer is 30 times than sand casting and 5 times than centrifugal casting, and doesn't produce white iron, the eutectic cell volume of continuous cast iron is one eighth to one tenth compare with traditional cast iron. The density of graphite nodule in ductile iron can reach 300-700 pcs/mm2. Therefore, all reason above improve the strength and toughness of continuous cast iron.

(4) Free machining. The high speed cooling make the hardening phase (such as boride, steadite) not appear like reticular, massive or thick, but diffuse like fish bone and pane in shape, moreover, there are tiny graphite flakes inlaid hardening phase. It's free machining in BrinellHardness the range of 250-300HB. However, the Brinell Hardness of 250 is top limit to common metal materials.

(5) Uniform composition of tube wall. The convection mixing of liquid column caused by marching type drawing in crystallizer make the composition of tube wall well-distributed, and concentration gradient very little.

(6) High productivity. To the wall thickness of tube under 10mm, the speed of continuous casting is 1 meter/min, to the wall thickness of tube under 20mm, the speed of continuous casting is 0.5 meter/min, which is high efficiency that centrifugal or other casting tech couldn't reach.

Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
When the condition does not allow enough slope, it is necessary to do wall protection and other means to ensure safetyRemind me, such a big pipe, dig deep in two ways. One is the depth diameter (range at the junction of 1.6 m in length and 500 for manholes and operation. The lower bolt assembly when) there is a depth diameter plus 500. and then in the trench laying branch the pier, installed after the fine stone tamped backfill.Can also be buried directly with the pipe diameter, and then put into the assembly. This method requires a large space on the ground, otherwise, the volume is too large after assembly, weight is too heavy, may cause damage to the pipeline and personnel injuries
Q:What are the differences between ductile cast iron pipes and centrifugal ductile iron pipes?
Small, thin pipe fittings are usually rolled or continuously cast, and large, thick pipes are usually centrifugally cast. Compared to sand casting, the tissue is compact and homogeneous.
Q:How long does the cast iron pipe of indoor direct buried sewage need to be examined?
Cast iron pipe, cast cast pipe. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. 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.
Q:What do ductile iron pipes need to connect with three? Can I contact it directly?
Old craft1. dozen to lead lead; cut into strips, with a file play in the interface2. use expanded cement with asbestos3 use the asphalt
Q:How much is the installation cost of the ductile iron tube?
Water supply pipe is the first choice, with high cost performance. 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 through various anti-corrosion methods;
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:How much is the working pressure of ductile iron pipe used in water supply pipe and how is MPa determined?
Upstairs are positive solutions, but now outdoor buried water pipes are using steel wire mesh skeleton, plastic composite pipe instead of ductile iron pipeThe general pressure grades used for water supply pipes are 1.0MPa and 1.6Mpa
Q:How can the ductile iron pipe be welded?
The nickel electrode cold welding, such as Z408
Q:What is the exterior anticorrosion of nodular cast iron pipes?
According to the national standard GB/T13295-2008, external corrosion prevention technology of ductile cast iron pipe is coated with asphalt paint, spraying zinc, widely used in domestic manufacturers is spraying zinc spraying asphalt layers corrosion, zinc layer thickness: 130 grams / square meters, the thickness of asphalt 75Um.
Q:Will the quality of ductile iron shrink?
Fool you. It is normal that the surface shrinks and goes down, but it can not be said to be good.
