Q:What does "1.5" steel tube mean?
DN refers to the nominal diameter of the pipe (also known as nominal diameter), all piping accessories in the piping system are numerically represented in order to distinguish the parts that are represented by threads or outside diameters. Nominal diameter is used as a reference, after rounding the figures, and processing numerical value is not exactly the same, nominal diameter can be expressed as metric mm, also can be used in English in.
Q:Welded and seamless steel pipe how to distinguish?
Different uses:Mainly used for seamless pipe or structural parts of the transmission fluid, mainly used in machinery industry, and seamed steel pipe is mainly used in the construction industry, such as water, gas, compressed air and low pressure fluid. But seamless steel tubes are used in all pressure pipes.
Q:What is the diameter of the steel tube DN20?
Stress: the nominal diameter is not the outer diameter of the pipe, nor the inner diameter of the tube. It is not the average value of the inside and outside diameter (the nominal diameter of the equipment refers to the outer diameter).
Q:How to make the internal tooth of the steel pipe?
Cylindrical thread can be used, if the tube is too long, you may consider a short tube with thread, and then welded to the long tube. Taper thread is more difficult to use than ordinary vehicle, and the tap is generally considered. The tap can be clamped on the tailstock.
Q:How can galvanized steel pipe be connected with stainless steel pipe?
Welding methods are used to connect. Because galvanized pipe is in fact carbon steel pipe, so galvanized pipe and stainless steel pipe welding, in fact, carbon steel and stainless steel welding, welding of dissimilar materials.
Q:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.Elbow is a common connecting pipe used in plumbing and heating. It is used for the connection of the bend of pipe, and is used to change the direction of pipe.
Q:What is an electric welded pipe (EFW)? Seek help!
It is through one or several consumable between the electrode and the workpiece on the metal heating the metal between a process with the arc to metal and filler material fully melted, no pressure, filler metal parts work from all electrodes
Q:What does "DN25 PN16" mean?
The welded steel pipe can be divided into thin-wall steel tube, ordinary steel pipe and thickened steel tube according to the thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube. "DN25" means the inner diameter of the steel pipe is 25MM.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
In general, steel is divided into two groups according to their chemical composition: carbon steel and alloy steel;(1): carbon steel low carbon steel (C = 0.25%); carbon steel (0.25% < C < 0.60%); high carbon steel (C = 0.60%)(2): alloy steel, low alloy steel (alloy is less than or equal to 5%); in steel (5% < < 10% alloy; high alloy steel (alloy) = 10%)Carbon seamless steel tubes are mostly pipes for mechanical engineering structures and pipes for conveying fluids.
Q:What is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory.
