Q:Will the cast iron pipes rust?
Ductile iron pipe corrosion process is good, decided whether it will rust. Whether it will rust or not, the key is whether the anti-corrosion process of the nodular cast iron pipe is in place.
Q:What pipe can be used to replace the cast iron pipe in the water supply? Thank you
You are mistaken in concept. The cast iron pipe is the sort of connection method. The ductile iron pipe is classified according to the material.
Q:What are the advantages and disadvantages of spheroidal graphite cast iron?
Therefore, ductile iron pressure containing parts are treated with a ferritizing annealing cycle, the globular structure of ductile iron internal can also eliminate the crack phenomenon of iron easy to produce graphite flakes within the. In microscopic photographs of ductile iron, cracks can be seen and terminated after the parade of graphite balls. In the ductile iron industry, these graphite balls are called "crack terminator" because they have the ability to prevent fracture.
Q:Will nodular cast iron pipes rust?
Qualified ductile iron pipe requires lining standard cement. The outer wall of pipe needs spraying zinc treatment and asphalt paint coating, and other epoxy resin paint can also be selected. Qualified ductile iron pipes can be used for more than a hundred years. The main place where rust is easily exposed is where the outer wall meets the soil because of its high humidity and high oxygen content. Qualified anticorrosion can effectively resist rust, its process principle can not give you the details.
Q:Is the spigot and socket connection of the ductile iron tube reversed?
The whole process is formed by the radial compression of the pipe blank and the stretching process of the branch pipe. Different from the hydraulic bulging three, the metal of the three way joint pipe is compensated by the radial movement of the tube blank, so it is also called radial compensation process.
Q:How can the cast iron pipe be connected?
Cast iron pipes are flanged and socket connected
Q:How much is the manual installation fee of ductile iron pipes from 100 to 150 per metre?
According to the various connection modes after the installation of artificial fee at =8.7~9.0 yuan (about /M this is pure artificial installation fee, no other costs to calculate, if packet labor costs and construction should be appropriately increased when installed).
Q:What material is ductile cast iron 235A?
Pig iron is an alloy of iron and carbon carbon content more than 2%, pig iron carbon content is generally in 2.5%--4%, including C, SI, and Mn, S, P and other elements, is the use of iron ores in blast furnace products. According to the different forms of carbon in pig iron, and can be divided into pig iron, cast iron and steel ball ductile cast iron. Several precipitation of spherical graphite cast iron. The cutting action on the metal substrate than spheroidal graphite flake graphite cast iron, the strength of the matrix organization strength of 70 ~ 90%, the tensile strength is up to 120kgf/mm2, and has good toughness. Ductile iron chemical composition besides iron usually contains: the amount of carbon 3.3.8%, silicon 2.3.0%, manganese, phosphorus, sulfur and no more than 1.5% of the total amount of rare earth, magnesium spheroiditic agent.
Q:Ductile iron pipes lined with cement mortar in the water (living water, water in the 6.9-7.3) in the early pH, why pH increased? How to solve this problem?
The basic characteristic of ductile iron pipe of ordinary cement mortar lining the inner wall of the tube will make passivation, have antiseptic effect, but in the initial stage of using cement mortar lining will be the alkali component separation, so that the pH value of water increased to influence water quality
Q:What is a slide in type T flexible interface?
The disadvantage of the T type interface is the ability to prevent pipe slippage because the interface can not withstand axial forces, so the base of the line is positioned against the axial forceFigure slider type (type T) interface (TYT type)The T type interface utilizes the self sealing action of the rubber ring to preserve the tightness of the water, as shown in the following figure. The so-called self sealing action is that the rubber ring is subjected to fluid pressureFig. interface rubber sealWhen the actual contact pressure to form a rubber ring is equal to the contact pressure and the fluid pressure generated by the installation of pre compression on the rubber ring and the new contact pressure. Due to the contact pressure than the fluid pressure, so the interface has good sealing function.
