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:Can the sealing ring of ductile iron pipe be reused?
The sealing ring is hard to install and take off. I have been in this line for six years. I haven't seen it removed. The rubber ring itself is not expensive. It is not necessary to reuse it.
Q:What material is the cutting tool for ductile iron?
They are all hard alloy materials, all of which are CVD coatings, but the products produced by different manufacturers will be very different.
Q:What are the meanings of cast iron pipe wall thicknesses LA, A and B respectively?
Cast iron pipes (Cast, Iron, Pipe), cast cast pipe. 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.
Q:How can stainless steel pipes and ductile iron pipes be joined?
The utility model can be connected with a wide range flange joint or a wide range flexible joint
Q:Does the cast iron pipe need separate corrosion protection?
The pipe has been antirust in the production process and can be used directly
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:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
600-3 is pearlite + a small amount of ferrite matrix ductile iron. Pearlite edge region. 10%, center. 70600-3. Two sets of numbers indicating the grades and mechanical properties of nodular cast iron. The former represents the minimum tensile strength
Q:Ductile iron gears are generally treated without heat treatment
Heat treatment must be necessary, generally annealed first to machine, after quenching or nitriding treatment
Q:Can cast iron pipes not be used for domestic water supply and drainage?
Yes, the main use is, outdoor water supply pipe can be PE or ductile iron (socket connection). Indoor water is now used in general plastic pipes, but in the past seems to be able to use ductile iron, as for drainage, generally do pressure type drainage, when the choice is cast iron pipe. There are also indoor fire pipes using welded steel tubes or ductile iron.
