Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
Choose carbide or whole carbide drill, about 90HRC in hardness. But it requires a high number of drills, around 3000.
Q:Is the fire hose capable of using rapid repair joints?
Installation joint. Insert the socket into the socket to coincide with the central axis of the pipe or pipe to be joined. Use a guide chain to tighten the pipe member until the pipe mouth enters between the two white lines.
Q:What effect does magnesium play in nodular cast iron?
The role of magnesium as spheroidizing agent used in iron spheroidizing treatment, promote water ink is made of iron, carbon in liquid iron spherical graphite precipitation.
Q:The design uses water supply ductile iron pipe, PE corrosion protection pipe, HDPE pipe, please ask that good? What's the price of the two?
PE pipe is hot melt connection (with thick wall smooth type, don't use the wavy), has the advantages of convenient connection, not affected by terrain, but should pay attention to cold and rain when try not to do, otherwise easily lead to cracks or Water Leakage interface touch interface. The disadvantage is not pressure, heavy machinery on the flat, but the problem is not, as long as the water does not leak, do not need to redo. Also, PE price volatility is relatively large, the size of the price difference is relatively large, a few more runs to ask the price.
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?
Is it better to use precoated sand, but only a little higher cost?.
Q:What is the difference between cast iron pipe and seamless steel pipe and galvanized steel pipe?
Galvanized steel pipe: divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the time being. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries also issued a civilization, indeed from two, 000 years since the galvanized pipe as a water supply pipe, the New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe. Hot dip galvanized steel pipe is widely used in fire, power and highway.
Q:What is the DN400 installation charge for ductile iron pipes?
1. hourly wage or piece wage: refers to the hourly wage and work hours or the work done by the unit price to pay individual labor remuneration.2. prize: refers to the excess labor and increase revenue of remuneration paid to individuals. Such as saving prize, labor competition prize, etc..3. subsidy: refers to compensate workers special or extra labor and other special reasons for the subsidies paid to individuals, and in order to ensure that the impact of inflation on real wages paid to individual price subsidies. Such as mobile construction allowance, special area construction allowance, high temperature (cold) operation, temporary allowance, aerial allowance and so on.
Q:Ductile iron pipe, socket connection, pipe length, you can cut open it?
Yes, but the pipe that needs cutting is a cut off pipe with a scissors mark.
Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
Then, according to the soil characteristics, different slopes are calculated, and the width of the excavation is calculated according to the depth and slopeIf the soil is soft, high water content and easy to collapse, the excavation width will be wide, otherwise the slope will be steep and the excavation width will be narrow
Q:What is the difference between a PE fire hose and a ductile iron pipe?
Cast iron pipe: 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. Labor intensity is small. 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.
