Q:How can the cast iron pipe be connected?
Cast iron pipes are flanged and socket connected
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:What is the content of silicon in silicon molybdenum ductile iron?
High silicon molybdenum ductile cast iron is developed for end users successfully reduces the cost, and the castings have high strength, good oxidation resistance, and has good performance under thermal cycling condition. This kind of ductile iron silicon content of 4% molybdenum content 0.6%-0.8%, currently designated as many car manifold and turbocharger shell, and molybdenum content than the silicon alloy casting 1% more for special high temperature exhaust pipe, heat treatment. High silicon molybdenum alloy nodular cast iron castings used in the production of automotive turbocharger.
Q:Some questions about the bearing capacity of nodular cast iron pipes!
The minimum tensile strength of ductile iron is 400MPa, and the stresses can be calculated according to the wall thickness, diameter and safety factor.
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: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:Do ductile iron pipes have inner enamel?
If the market supply is indeed difficult, can be done by the owners, Design Institute of supplier relationship; if the design institute requires it to provide products can persist in wilfully and arbitrarily, the available information (if the market can not supply, design a hair ah).
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:What is the exterior anticorrosion of nodular cast iron pipes?
Spraying anti-corrosion paint, usually first spray a anticorrosive paint, and then primer 2, paint 2!
Q:Will the quality of ductile iron shrink?
This is a ductile iron is prone to problems, manhole covers, large flat pieces, you have to see clearly, and some appear to be concave, not shrink, it may be caused by large gas emissions, not out
