Q:What's the use of steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. (
Q:What is an electric welded pipe (EFW)? Seek help!
Pipe and pipe fittings should be suitable for the gap, usually with micro force insertion is appropriate, the gap is too large or too small will affect the quality of the interface.Check the depth of the plug and slip the spigot into the socket and position correctly.
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:RC is it welded steel pipe or galvanized steel pipe?
RC pipe is galvanized steel pipe, usually followed by the diameter, such as RC50, that is, 50mm galvanized steel pipe.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.
Q:What quota should be installed for heating seamless steel pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
The pipe material of heating pipe network should be designed according to the requirement. When the design is not specified, the following requirements shall be met:1 when the pipe diameter is less than or equal to 40mm, welded steel pipe shall be used.2 when the pipe diameter is 50 ~ 200mm, welded steel pipe or seamless steel pipe shall be used.3 when the pipe diameter is greater than 200mm, spiral welded steel pipe shall be used.
Q:What are the main aspects of precision steel tubes?
Its inside and outside diameter size can be accurate to less than 0.2mm, and it is widely used in the manufacture of precision machinery parts and engineering structure when the bending resistance and torsion strength are the same. It is also used to produce all kinds of conventional weapons, guns, shells, bearings and so on.
Q:DN80 seamless steel tube, what is the standard thickness?
Generally speaking, the diameter of the pipe can be divided into outer diameter, inner diameter and nominal diameter. Tubes are made of seamless steel tubes. The outer diameter of the tubes is indicated by the letter D, followed by additional outer diameter dimensions and wall thicknesses such as seamless steel tubes with an outer diameter of 108.
Q:How seamless steel tube is formed?
Overview of two kinds of steel pipe process:1, cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.2. Hot rolling (extrusion seamless steel tube): round tube billet, heating, piercing, three roll cross rolling, rolling or extrusion, removal of pipe, sizing, reducing (diameter or reducing), cooling, blank tube, straightening, water pressure test (or flaw detection), marking and warehousing.
