Q:What is the relationship between continuous cast iron pipe and ductile iron pipe?
Continuous cast iron pipes are usually grey cast iron pipes. Its tensile strength and elongation are much lower than those of nodular cast iron. In chemical composition, grey cast iron has less carbon content than nodular cast iron. According to the organization, the graphite form of gray iron is flaky, and the graphite form in spheroidal graphite cast iron is spherical.
Q:Principles for the antiseptic treatment of ductile iron pipes
Anti corrosion process of ductile iron pipe:1. asphalt 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.2. cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.3. epoxy coal tar coatingThe epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipes. It is a two component coating with a high adhesion and a very smooth surface
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
The sewerage system uses ductile iron pipes. The premise should be pressure pipe drainage. It must be a special occasion, otherwise the cost will be high. In general, precast concrete pipes are recommended.
Q:Is there a kind of pipe called lined ductile iron pipe? Seeking manufacturers?
The 10kg pressure ball tube is also used as a drain, and the second is the W ductile iron pipe, i.e., without spigot, ductile tube, or lined ductile iron tube.
Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Heavy thermal and mechanical shock, high temperature or low temperature, corrosion resistance and dimensional stability. To meet these changes in use conditions, ductile iron is available in many grades, providing a wide range of mechanical and physical properties.
Q:The benefits of ductile iron castings
Its performance is close to carbon steel, but it has good casting performance, easy molding, better machinability than cast steel, better heat resistance, corrosion resistance and wear resistance than steel. And a very important one: cheap.
Q:Method for joining cast iron pipes
The connection between the pipe and the pipe adopts the form of socket type or flange disk interface. According to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with rubber ring, which allows a certain degree of corner and displacement, so it has good seismic resistance and tightness. It is easy and quick to install than rigid interface. It has little labor intensity according to the casting method.
Q:How can the steel plastic composite pipe be connected with the cast iron pipe?
The clamp hoop is a connecting device for connecting pipe fittings, valves and pipe fittings with grooves. Used in the fast joint between the role of tightening, the general two joints with gaskets, rubber, and silicone, ptfe.
Q:Comparison of ductile iron pipe and spiral steel pipe
Spiral welded pipe: inner wall smooth, welding connection, a small amount of pressure, need additional anti-corrosion
Q:Method for cutting large diameter ductile iron pipe
When the oxygen and acetylene volume ratio is greater than 1.2, is formed. As more oxygen, burning, the flame length is shortened obviously, cone tapered inner flame almost disappeared, and a strong desire. Making due to oxygen, the oxidation of metal, so are not widely used, only used for welding of brass, to prevent evaporation of zinc.
