Q:What's the actual size of the DN25?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:What type of steel pipe dance is used in general?
According to international competition practice, the standard size of steel tube is 40 mm or 45 mm in diameter, and the 45mm is usually used. The height of the steel pipe is not less than 3.3 meters and not higher than 4 meters.
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:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
With this kind of steel manufacturing products, usually by heat treatment (normalizing and tempering); parts made before use, usually need to go through refining or chemical surface treatment (carburizing and nitriding), surface quenching or high-frequency quenching treatment. Therefore, according to the chemical composition (mainly carbon content), heat treatment process and use of different, such steel can be roughly divided into carburizing, quenching and tempering and nitriding steel three.
Q:RC is it welded steel pipe or galvanized steel pipe?
Common pipelines in construction are as follows:SC: welded steel pipeTC: wire tubes, thin steel tubesPC: rigid plastic pipesCT: cable trayCP: metal hoseSR: steel grooveRC: water gas pipe
Q:What are the specific differences between flexible pipes and rigid pipes?
Structurally:A rigid waterproof sleeve is welded with a water stop ring outside the steel pipe;The flexible waterproof casing pipe is welded on the outside of the 3 side wing ring, 4 screw buckle, inside a welding piece with a rubber ring, the outside and do a flange, with 4 double head bolt, welding a steel pipe, the pipe installed, the flange is installed. The screw fastening, tightening the apron is bigger, more Water Leakage, generally in the waterproof requirements of relatively high places, such as the pool of water.
Q:Can the KBG25 steel tube hold 4 six types of cables?
1 of the six lines of cross-sectional area of about 25 square millimeters, 4 to 100 flat, KBG25 cross-sectional area of about 490100/490=20.4%, just over the specifications, so short distance and less elbow can be worn. However, due to the construction of pipes are generally not standardized, elbow more, and do not use special elbow (site bending), so KBG25 wearing 4, six kinds of cable are more difficult.
Q:What are the main aspects of precision steel tubes?
Its inside and outside diameter size can be accurate to less than 0.2mm, and it is widely used in the manufacture of precision machinery parts and engineering structure when the bending resistance and torsion strength are the same. It is also used to produce all kinds of conventional weapons, guns, shells, bearings and so on.
Q:45 and 316 which steel tubes are of high hardness?
No. 45 steel for high-quality carbon structural steel, the hardness is not high machining, used to make the template, mould studs, guide column, subject to heat treatment. 45 steel quenched and tempered hardness between HRC20~HRC30; 45 steel quenching hardness between HRC55~58, the limit value of up to HRC62.
Q:Why seamless steel pipe called seamless steel pipe?
Steel pipe is divided into seamless steel pipe and welded steel pipe two kinds: seamless steel pipe is ingot or tube billet, through the perforation made capillary, and then by hot rolling, cold rolling or cold drawn made, so seamless steel pipe is divided into hot-rolled and cold drawn two categories. Welded steel pipe is through the steel plate or steel strip after bending forming, and then welded to make, according to the form of weld is divided into longitudinal welded pipe and spiral welded pipe two kinds. It is obvious that seamless welded pipe has no weld and that welded steel pipe has weld line.
