Q:What does "DN25 PN16" mean?
DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of universal 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; in order to make the tube, pipe connection size uniform, with nominal diameter (also called nominal diameter, nominal diameter).
Q:Seamless steel tube with the tube with what is the difference?
Seamless steel tube is integrally formed with welded steel pipe steel plate butt welding and welding seam.
Q:What is the difference between steel pipe and round steel?
Widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:Will the steel tube dance?
Pole dancer performing double pole dance performance is much higher than single pole dancing difficult, because not only refers to the double pole dance together the two pole dance, two people should pay attention to the dance and tube movement, if two people do not fit to dance moves and skills on the tube action, you jump you. I jump, that wasn't a real double pole dance, dance like a double tube. If the two dance movements and pipe movements are not good enough or not natural enough, they will destroy the effect of the whole dance and make the audience feel that the dance is chaotic and not beautiful, so it is better to see a single pole dance. But the dancer's double pole dance performance is good, more powerful than single pole dance, and more aesthetic and artistic.
Q:What time what time for gas pipeline steel pipe PE pipe
City network is generally medium, are generally. PE pipe high pressure pipe with building the required distance, is generally used around the high pressure pipe laying (high pressure gas supply capacity, and can play the role of peak shaving), the city zone by the supply voltage to the voltage, residential building regulation boxes of low voltage supply to the users.
Q:Is hot dipped plastic pipe steel?
The hot dipped plastic steel pipe is a steel pipe, and it is made of special antiseptic treated composite steel pipe.
Q:How do you solder purple copper plate and steel tube?
When the copper and copper tube size is too large, argon welder welding, DC argon arc welding machine, of course, when DC argon arc welding welding belongs to welding, argon arc welding of brass with Wei Odin 204S welding, the argon arc welding wire for gas welding is not brass wire, this concept must be clear, the wire diameter of 2 80-120A, welding current parameters, if the copper thickness is relatively thick, with a red copper welding after welding preheating in advance.
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
1, the process is different, one is chemical treatment, one is physical treatment; hot-dip galvanized coating is reliable, not easy to fall off2, hot-dip galvanized coating thickness, so strong corrosion resistance. And zinc plating (electroplating) coating evenly, surface quality is better, coating thickness is generally between a few microns to more than ten microns.3 hot galvanizing is a chemical process, which belongs to electrochemical reaction. Zinc plating is a physical treatment, just brush a layer of zinc on the surface, there is no galvanizing inside, so the zinc layer is easy to fall off. Hot-dip galvanizing is used in building construction.4 、 hot galvanized pipe is to make molten metal and iron matrix reaction and produce alloy layer, so that the substrate and coating two combination.
Q:How is the steel pipe dance installed at home?
Perforated steel pipe, is very troublesome, need support to the roof and drilling in the room, the bottom with tripod frame fixed nail, and welding, installation is very troublesome;
Q:How seamless steel tube is formed?
Hot drawing or cold drawing. The so-called cold is the billet from the thick wall tube is not heated, oil lubrication, with a steel sleeve inside, gradually elongated. Hot drawing is to make the billet tube red, do such work, generally thick wall applicable.
The company has successively passed ISO9000 quality system, the American Petroleum Institute API, and also earned the environment healthy license, national special equipment manufacturing license.
