Q:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN is a kind of Engineering path, not the actual value, due to the different standards, so the actual corresponding values is not the same; phi is refers to the actual value, the same national standard pipe inside the steel pipe, the actual value is the same, for example, GB/T8163 and GB GB fluid pipe spiral pipe and GBT/T9711.1 GB/T12459 the same nominal diameter corresponding to the actual value is the same as the actual value; and American Standard steel standard ANSI B 16.38 and ANSI B 16.9 standard American Standard fitting the same nominal correspondence is the same. If marked, the nominal diameter should be added DN, and the actual value can be omitted.
Q:What is the diameter of the steel tube DN20?
1, nominal diameter is nominal diameter, or nominal diameter, or nominal size.2, nominal diameter is a variety of pipe and pipe accessories generic caliber. The same nominal diameter of the tube and pipe accessories can connect with each other, with interchangeability. It is not a real sense of the pipe diameter or diameter, although its value is closer with the pipe diameter or equivalent, is a convenient integer for reference only, are not strict with processing size. Nominal diameter is not the outer diameter, nor the inner diameter, but a nominal size similar to the diameter of the ordinary steel pipe. In order to connect the pipe and pipe fittings in a uniform dimension, each nominal diameter corresponds to an outer diameter, and the inner diameter value varies with the thickness.
Q:Does seamless steel tube have a bend of 135 degrees?
Other name: 90 degree elbow, right angle bend, love bend, punching elbow, pressing elbow, mechanism bend, welding elbow, etc..Usage: connect two pipes with same nominal diameter or different pipe, make the pipe bend at 90, 45, 180 degrees and various degrees.Bending radius is less than or equal to 1.5 times the diameter of the elbow. It is 1.5 times larger than the pipe diameter and belongs to the elbow
Q:Is the PVC tube a plastic tube or a plastic tube?.
PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. Polyvinyl chloride (Poly, Vinyl, Chloride, PVC), it is obviously impossible to steel, we often say that iron and steel, the steel must be the main component of iron, Fe, inorganic. And PVC, polyvinyl chloride, is an organic substance. Therefore, PVC can not be called steel, and PVC constitutes a large number of substances, not confined to the pipe type.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.Press materialSteel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
Q:Is the electric pipe used with steel pipe or PVC pipe?
Electric pipe laying is generally divided into the following circumstances:1) the explosion-proof area must be galvanized steel pipe and explosion proof flexible pipe (used for front end equipment connection);2) non explosion-proof area can use KBG pipe or PVC tube, the former is higher cost, but the installation is firm, the latter is low cost, easy to construction, and in the rain where it will not rust, but compared to the KBG pipe may be damaged.
Q:Galvanized steel pipe DN100 and SC100
DN is the meaning of "bore", also expressed in water supply and drainageSC is welded steel pipe, generally GB tube, that is, thick walled steel pipe, look at the design requirementsMT refers to the wire tube, usually thin-walled tube, there are KBG and JDG
Q:How big is the seamless steel tube of DN50?
This refers to the diameter of the steel pipe is 50 mm, DN50 steel pipe diameter is 60.3 mm, that is, 60.3 * 5 mm steel pipe
Q:Seamless steel pipe 8162 and 8163 what is the difference?
GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
Q:What does "steel pipe SC" mean?
SC (run in welded steel duitconSC is the line laying mode GB letter of wire is worn steel pipe laying (welded steel pipe, low pressure fluid) SC70 said the conductor by low pressure fluid DN70 welded steel pipe as protection pipe laying, DN70 said the nominal pipe diameter is 70mm, the nominal pipe diameter is 70mm (a series of values, the actual diameter slightly different).
