Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
The outer steel tube diameter is 48mm, the tube wall thickness is 3mm, the theoretical weight per meter is 3.3291kgCalculation formula: (outside diameter wall thickness) * wall thickness *0.02466(48-3) *3*0.02466=3.3291kg
Q:What's the actual size of the DN25?
DN25 refers to the theoretical size of the inner hole of the pipe. That is to say, the theoretical dimension of the inner diameter of the pipe is 25 (the metric tube refers to the inner diameter, and the English tube is also to indicate the inner diameter, for example: 3/8, the inner diameter is 9.525, and the diameter of the 1/2 is 12.7, and the diameter of the 5/8 is 15.875). The outer diameter is theoretical in diameter, plus the wall thickness specified by the state (which is artificially specified and has no formula)The theoretical diameter of DN25 is 25, and the outer diameter is Phi 33.7 and phi 32(but there is also the outside diameter of the mark. The mark is: the outer diameter * wall thickness, such as: 32 * 2, that is to say, the outer diameter is 30, the inner diameter is 26)
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:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
Galvanized steel pipe is a kind of antirust steel pipe, often used in relatively high water supply pipeline or hot water pipeline, the price is higher, can use for at least 30 years;PPR pipe is a kind of polypropylene plastic, which is commonly used in environmental protection plastic pipes, but only suitable for low temperature occasions. It is mainly used for water supply;
Q:What are low-pressure carbon steel tubes?
Any of various steels that contain less than 2.11% of the mass of carbon but contain no alloying elements. Sometimes referred to as plain carbon steel or carbon steel.Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.1) according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy to cut structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two kinds;(2) by refining methods can be divided into open hearth steel, converter steel;(3) according to deoxidization methods, they can be divided into boiling steel (F), killed steel (Z), semi killed steel (b) and special killed steel (TZ);(4) according to the carbon content of the steel can be divided into low carbon steel (WC = 0.25%), carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%);(5) according to the quality of steel, carbon steel can be divided into ordinary carbon steel (phosphorus, sulfur, higher), high quality carbon steel (low phosphorus and sulfur) and high quality steel (lower phosphorus and sulfur) and super quality steel.Description: the carbon content in general carbon steel is higher, the hardness is higher, the strength is higher, but the plasticity is lower.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
The difference is: 20# ordinary steel seamless steel pipe. 20G is the type of steel for high pressure boiler tubes.
Q:The plastic pipe and steel pipe difference
The steel plastic pipe is a general term, which includes plastic pipe, plastic lined pipe. Plastic pipe external coating, zinc coated and so on in Shanghai, Fujian, Portland, professional in this area
Q:How do you solder purple copper plate and steel tube?
The copper plate and the steel tube are brazed by brazing or argon arc welding.
Q:What is the process of spiral steel tube production?
Shear forming: on the production line will be along the outer edge of the spiral plate winding tube.
Q:How long is the seamless tube?
Generally finished seamless steel tubes are less than twelve meters, mainly for the convenience of shipment.In times of rolling (processing), the steel pipe can reach 80 meters or longer.
