Q:What are the specifications for the installation of water ball iron pipes?
Ductile cast iron pipe is characterized by mild, high, thin wall, pressure resistance, impact resistance, corrosion resistance, seismic resistance and other properties. The flexible interface is used for the pipeline interface, and there is a certain elongation and deflection angle. The utility model has the advantages of the raw iron pipe and the steel pipe material, and avoids the defects of iron and steel.
Q:How much pressure can the ductile iron pipe socket meet?
If you let him as the supporting points, I do not recommend this
Q:Can centrifugal cast iron pipe be galvanized or coated with asphalt which is good for corrosion prevention?
The centrifugal ductile iron pipe has the advantages of zinc coating and asphalt coating, and it is used in combination with two. By spraying zinc and epoxy coal tar coating of ductile iron pipe wall (or epoxy resin paint, polyurethane, etc.) wall using Portland cement (or epoxy powder, epoxy, polyurethane, ceramics etc.) wall coating can effectively active substances in soil and the formation of an insoluble zinc salt protection tube, the internal coating can inhibit corrosion of pipe body fluid medium.
Q:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
This is such a small piece, do not worry about shrinkage, mainly pay attention to sand hole and slag. With Disa wet molding line, a box of more pieces, suitable for mass production, defects will be relatively less. By using other methods (resin sand coated sand, etc.) can also be the main attention, don't type it, then the level of liquidity and relatively ductile iron, gray iron poor, sand and gas can not go up, sand holes or pores will spread in the discus plane.
Q:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
As the HDPE pipe is made of hot melt connection, the construction is more difficult, and the installation cost is about 40% higher than that of the nodular cast iron pipe.
Q:What material is ductile cast iron 235A?
Nodular cast iron by spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than carbon steel. The strength of nodular cast iron is a kind of high strength cast iron material developed in 50s twentieth Century, its comprehensive performance is close to the steel. It is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts. Ductile iron has been the rapid development of cast iron material for application of gray cast iron, only very widely. The so-called "iron steel", mainly refers to the ductile iron.
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:Is there any cast iron pipe used in the fire hose?
No, I think so. In theory, you can.See if the specifications have any requirements for the material.
Q:Is the cast iron pipe buried in need of antiseptic treatment? What kind of anticorrosive materials are used?
Need general brush oil can.
Q:If the ductile iron pipe is broken, can we use rush repair?
In this way, manpower, material resources and financial resources can be saved, time can be saved, and unnecessary troubles to the citizens' water supply can also be reduced.
