Q:Material of welded steel pipe
GB/T3091-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is Q235 grade a steel.
Q:What does "buried steel pipe" 6*2SC100 mean?
This is the electrical drawings, such as water supply and drainage, HVAC is that DN, SC is the laying of electrical wiring, which is defined as threading pipe laying. 100 is the nominal diameter of the pipe, unit millimeters.
Q:What's the difference between steel pipe and pipe fittings?
Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
Q:How to make the steel pipe spray paint is not easy to fall off?
You're not usually advised to do it yourself, because you can't do it yourself. General powder coating, spray before the treatment is very strict, to be high temperature baking, and their spraying are dry paint, it does not add hardening agent, that is, the surface dry, but not hard, not wear-resistant. So don't scrape off the paint, or you'll look good after spraying, and it will be ugly in a few days,.If you really like to look good, you can buy some stickers back to paste, without affecting the appearance..
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:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Seamless steel tube processing technology:1.1 、 hot rolled seamless tubes are usually produced on automatic rolling mills. After checking and cleaning the surface defects, the solid tube is cut into the required length, centring on the end face of the tube blank, then sent to the heating furnace and punched on the piercer. At the same time, the hole rotates and advances continuously. Under the action of the roller and the plug, the inner cavity of the pipe blank is gradually formed, and the cavity is called the capillary. Sent to the automatic tube rolling mill on rolling. Finally, the thickness of the whole machine is the same, and the diameter of the sizing machine is determined to meet the specifications. It is an advanced method to produce seamless steel tube by continuous rolling mill.1.2, in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold rolling is usually carried out on a two roller mill, where the steel tube is rolled in the annular groove made of variable cross section, round hole groove and stationary conical head. Cold drawing is usually performed in single chain or double chain cold drawn machines from 0.5 to 100T.1.3, the extrusion method will soon heat the tube blank in the closed extrusion cylinder, the perforation bar and extrusion rod movement, so that extrusion parts from the smaller hole extrusion. This method can produce smaller diameter steel pipe.Seamless steel pipe use: mainly used to transport fluid pipeline or structural parts.The main use of steel pipe joints (steel) two welded together, so the price is cheap, widely used.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
The urban water supply pipeline cleaning is a very necessary work, it can not only improve the transmission efficiency of pipeline to reduce energy consumption, but also to clear the pipeline dirt, remove two pollution, improve water quality, protect the people's physical and mental health.
Q:Which is cheaper, angle iron or steel pipe?
Angle iron and steel pipe, angle iron is cheap.
Q:Are metal spiral tubes the same as metal bellows?
The corrugated pipe is extruded by the extruder, the winding pipe is wound in a circle, and the prestressed metal corrugated pipe is a reserved channel.
Q:Is the PVC tube a plastic tube or a plastic tube?.
It's plastic tubePolyvinyl chloride (Poly, Vinyl, Chloride, PVC)PVC is a VCM monomer (vinyl, chloride, monomer), in peroxide, azo compounds and other initiators;
