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:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing condition of cutting is better than that of annealing. It is generally used to make the material with little force and high toughness.
Q:How many meters per ton of steel tube?
Formula of steel tube: (outside diameter wall thickness) * wall thickness *0.02466= per meter weight1000 divided by the weight per metre is how many meters per ton
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:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Sort by connectionThe connection way of steel pipe can be divided into: light pipe (pipe end without thread) and wire tube (Guan Duan with thread).The tube can be divided into ordinary tube and end tube.Thickening of the tube can also be divided into: extra thick (with external thread), internal thickening (with internal thread) and inside and outside thickening (with internal and external thread) and other vehicle wire tube.The wire tube can also be divided into ordinary cylinder or taper thread and special thread.In addition, according to user needs, wire tubes are generally equipped with pipe delivery.Plating characteristicsAccording to the characteristics of surface coated steel pipe can be divided into: Clarinet (not coated) and coating tube.The coating tubes include galvanized pipes, aluminium plated tubes, chrome plated pipes, aluminized tubes and other alloy layers.The coating tube has an outer coating tube, an inner coating tube and an inner and outer coating pipe. The commonly used coatings are plastics, epoxy resins, coal tar, epoxy resins, and various glass based anticorrosive coatings. Galvanized pipe is divided into KBG pipe, JDG pipe, threaded pipe, etc.
Q:How much is the tube?
The theoretical weight calculation formula of ordinary carbon steel tube is:The weight of each meter is kg/m= (outer diameter mm-, wall thickness mm) * wall thickness mm*0.02466For example: inventory 20# pipe diameter of 108*4.5 weight per meter:Kg/m= (108-4.5) *4.5*0.02466=11.485In accordance with the diameter of 108*4.5 steel pipe market price is 4500 yuan / ton as an example, we can know the diameter of 108*4.5 steel pipe per meter price: 11.485*4.5=51.68 yuan.
Q:What is the difference between steel pipe and round steel?
Steel tube or conventional weapons indispensable materials, barrel, barrel to steel pipe manufacturing. The steel pipe can be divided into round tube and special-shaped pipe according to the cross sectional area and shape. Because of the condition of equal circumference, the circle surfaceThe product is the largest and uses round tubes to hold more fluids. In addition, the ring section is subjected to an average force when it is subjected to internal or external radial pressure, so most steel tubes are round tubes.
Q:Which is cheaper, angle iron or steel pipe?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.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. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:What does "HBB" glass steel pipe mean?
Good water resistance, can be used for a long time in wet or water, and the ordinary composite is not water resistant, can only be used in dry environment.Heat resistance, fire resistance is superior to epoxy, glass fiber reinforced plastics and plastic and other materials. It can be used at 130 degrees for a long time, and not burned in case of fire.The utility model has the advantages of insulation, corrosion prevention, no rust, long service life, etc.. Generally up to 50 years, without maintenance.Simple and convenient installation and construction, because this product is light weight, high strength, laying construction method can properly solve the excavation due to road construction, exposed for a long time, prominent problems of city traffic, to achieve the excavation backfill pavement, buried at night, can normal traffic during the day.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
20G seamless steel tube is a high-pressure boiler tube. In addition to carbon content, 20G seamless steel tubes also have some trace elements that are more suitable for use as boiler pressure vessels. In addition, 20G also focuses on its physical performance. Such as bending, impact and tensile properties. 0G seamless steel tube is a kind of steel strip with hollow section and without seams. A 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.
