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 cast 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.
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: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:How can 4 inch ductile iron pipe be connected with 2 inch galvanized pipe?
The hot dip galvanized welded steel pipe galvanized pipe, galvanized pipe by welding without taking anti rusting measures (furnace welding and welding) steel pipe, seamless steel pipe or other metal pipe of the clarinet, process of hot dip galvanizing, the outer coating and galvanized layer to long-term corrosion of the steel pipe after processing.
Q:Ductile cast iron can replace copper sleeve
The tensile and compressive capacity of the ball milled cast iron is not as good as that of copper. The hardness of Rongchang graphite copper sheath can reach HB210
Q:What is ductile iron pipe?
Ductile iron pipe is a kind of cast iron pipe. In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the material have been better improved, with the nature of iron and the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
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 do we handle the leaking of the ductile iron pipe?
A hoop is a component that holds or ties another material with one material. It belongs to the fastener. The hoop holding device is composed of a hoop plate, a wing plate, a tension tie plate, a bolt and an inner liner. There are many kinds of hoop, hoop cable, wire rod hoop, hoop cable, wire hoop, stainless steel hoop are commonly used.
Q:What is the acceptance of cast iron pipe material?
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.
Q:How can the steel plastic composite pipe be connected with the cast iron pipe?
Use stainless steel clamps to connect.
