Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
General use seamless steel tube: is with 10, 20, 30, 35, 45# and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold rolled. Seamless tubes made of low carbon steel, such as 10, 20, are mainly used for fluid delivery pipelines. 45. Seamless tubes made of medium carbon steel such as 40Cr, used for the manufacture of mechanical parts, such as parts of automobiles and tractors. General use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel tubes are delivered in hot rolling or heat treated conditions. Cold rolled in heat treated state.
Q:What quota is reserved for buried DN20 steel pipe?
If it is reserved for embedded pipe pre buried steel waterproof casing, set of waterproof casing steel production and installation is to set the quota items, if the outdoor installation of welded steel pipe buried steel casing pre quota items, if it is a reserved hole, then there is no need to set the quota items.
Q:What is ND steel pipe?
ND steel 09CrCuSb steel is currently the most ideal "resistance to sulfuric acid dew point corrosion in steel (ND steel, ND steel, 09CrCuSb steel, 09CrCuSb steel), ND steel is widely used in the manufacture of economizer, served in the high sulfur content in flue gas of air preheater, evaporator and heat exchanger equipment for resist sulfur smoke gas dew point corrosion.
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Butt fastener: used for connecting two steel pipe joints.The base and the pad: is set up in the bottom of the pedestal pole, pay attention to the distinction between base and the base plate, usually with steel plate and welded steel pipe, base usually put on a backing plate, and the plate can be wood can also be plate.The foot board (see the diagram below), safety net (no explanation, this is very simple).
Q:How to make the internal tooth of the steel pipe?
At present, in our country, 300MW or 600MW or more large capacity sub critical and supercritical thermal power boilers are designed or imported abroad. Membrane internal wall tubes are widely used in membrane water wall.
Q:What's the difference between seamless steel pipe and welded pipe?
Welded steel pipe, also known as welded pipe, is made of steel or strip after the formation of welding welded steel pipe, usually 6 meters in length. Welded steel pipe production technology is simple, high production efficiency, varieties and specifications, equipment investment is less, but the general strength is lower than seamless steel pipe.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
304 stainless steel tube with the diameter of 25*2-3 said: material for 304 (the equivalent of the American brand, Chinese numbered S30408 stainless steel or 06Cr19Ni10 stainless steel), diameter (OD) for 25mm, for the seamless steel pipe wall thickness of 2 to 3mm.
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 does "SC50" steel pipe mean in civil engineering?
In the production of T-shape welded steel pipe, the wrong edges happen frequently, and the influence factors are many. In production practice, steel pipe degradation is often caused by dry, wrong and side errors. Therefore, it is necessary to analyze the causes and preventive measures of spiral steel tubes.
Q:What materials are used in scaffolding pipes?
The bamboo scaffold board made of bamboo or bamboo.
