Q:What's the difference between steel pipe and pipe fittings?
Pipe fittings: parts that connect pipes to pipes. According to the connection method can be divided into socket type pipe fittings, threaded fittings, flange pipe fittings and welding pipe fittings four kinds. Multipurpose; made of the same material as pipes. Elbow (elbow), flange, three pipe and four pipe (crosshead) and reducer (reducer) etc.. Elbow for pipeline corner; flange for the pipe and pipe interconnected parts, connected to the pipe end, three pipe for three pipe collection; four pipe for four tubes together place; for two pipes of different diameters connected to different diameter pipe.
Q:What does "DN25 PN16" mean?
Steel pipe DN25, PN16, first of all, for this annotation: pipe DN class, often used in welded pipe, such as welded pipe DN25. PN16 means pressure, that is, 16 kilograms (1.6MPa).
Q:What type of steel pipe dance is used in general?
The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Just name different, all refers to GB/T 3091-2015 "low pressure fluid transport welding pipe" contained in the galvanized pipe.Galvanized pipe means zinc plated, suitable for water, air, heating, steam and gas and other low pressure fluid conveying straight welded steel pipe, longitudinal submerged arc welding (SAWL) steel pipe and spiral seam submerged arc welding (SAWH) steel pipe.
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700
Q:What are the uses of welded steel pipes?
The spiral submerged arc welded pipe (SY5036-83) for the delivery of pressurized fluid is made of hot rolled steel strips for tube billets, often spirally formed, welded by double submerged arc welding and used for the transmission of pressurized fluid. The steel pipe has strong pressure bearing ability and good welding performance. After a rigorous scientific examination and test, it can be used safely. The utility model has the advantages of large caliber of the steel pipe, high transmission efficiency, and investment in laying pipelines. Mainly used in the transportation of petroleum and natural gas pipelines.
Q:Is the PVC tube a plastic tube or a plastic tube?.
Or polymer polymerized by radical polymerization under the action of light and heat. The vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resins. The material is a non crystalline material. PVC materials often use stabilizers, lubricants, auxiliary processing agents, pigments, anti shock agents and other additives in practical use. Is not flammable, high strength, excellent resistance to climate variability and geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
Q:Are metal spiral tubes the same as metal bellows?
Hello. The two are not the same. The difference lies in. The pitch of a spiral pipe is much larger than that of a bellows. The maximum material thickness of the spiral tube is much thicker than that of the bellow. The diameter of a spiral tube can be very large. But the bellows can't be too big in diameter.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).Bundled steel pipe
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
