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 is the manufacturing process of ductile iron pipes? Thank you
Made of nodular cast iron: a strict chemical composition, the content of silicon in molten iron requirements than the original carbon gray cast iron, nodular cast iron in reduced manganese, phosphorus, sulfur content of two liquid iron tapping temperature cast iron is higher than the ash, than the compensation sphere, conceived at the disposal of liquid iron temperature. Off line ball three disposal, that is to add a liquid iron ball agent four inoculation disposal of five nodular cast iron activity is poor, thus shorten the larger, higher demand for pouring temperature and pouring system larger size, more use of the riser cold iron by one condensation heat treatment criterion six iron is iron carbon alloy carbon content greater than 2%, the carbon content in ordinary industrial pig iron containing C, SI and 2.5%--4%, and Mn, S, P and other elements, is a product of iron ores in blast furnace. According to the difference in the shape of the carbon in the pig iron, it can be divided into several kinds, such as steelmaking pig iron, forging pig iron and nodular cast iron.
Q:How can the cast iron pipe of the ductile iron pipe be repaired?
First of all, to see whether the manufacturers do elbow pressure did not reach, if it is. That can only be replaced, if not, with a cast iron electrode welding repair.By the way, ductile iron can only be welded and not welded.
Q:What is cast iron pipe, specification for cast iron pipe?
A cast pipe made of cast iron. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings.
Q:What is the minimum pipe diameter of cast iron pipe?
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. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated.
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
The cost is low, the construction cost is low, and the schedule is fast. Such as PVC, PE double wall corrugated pipes, etc..
Q:How can the ductile iron pipes be treated with corrosion protection?
Bituminous paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying
Q:Ductile iron pipe joint damage, water leakage, want to see the connection with other pipe fittings, how to operate?!
The ductile iron pipe can be used as the plugging device for the big part
Q:How much is the manual installation fee of ductile iron pipes from 100 to 150 per metre?
Upstairs said 9 yuan per meter, about the same, if you use the special (ductile iron pipe installation tool) construction greatly saves the labor cost, very fast and convenient, can search, is a special tool for the new, I hope to help you.
Q:What is the difference between a cast iron pipe and a ductile iron pipe?
The ball compressive strength of ductile iron pipe is much higher than that of cast iron pipes, buried in the ground, the car is not easy to be crushed.
