Q:What material is RHS in the steel tube?
RHS is a rectangular hollow section steel. The RHS structure represents a rectangular hollow section steel.
Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
D108: refers to the outer diameter of 108mm;4: refers to the wall thickness of 4mm.
Q:What are the uses of welded steel pipes?
Low pressure fluid conveying galvanized steel tube (GB/T3091-1993) is also called galvanized pipe, commonly known as white tube. It is used for hot water, gas, air, oil, heating, steam, warm water and other generally low pressure fluid or other hot dip galvanizing (furnace welding or welding) steel pipe. The wall thickness of the steel pipe is divided into ordinary galvanized steel pipe and thick galvanized steel pipe. The end of the pipe is divided into non - threaded galvanized steel pipe and threaded galvanized steel pipe. The specification of steel pipe is expressed by nominal caliber (mm). The nominal diameter is the approximate value of the inner diameter. Usually used in inches, such as 11/2.
Q:What's the gate number of the precision steel pipe?
This kind of steel tube and ordinary hot-rolled seamless steel pipe and cold drawn seamless steel tube in the outer surface is different from the outer surface, and the diameter of the smooth finish of precision steel tube, stainless steel color and the same, inside and outside surface due to manufacturing reasons with a layer of oil.
Q:How are steel tubes represented?
If it is seamless steel pipe, welded steel pipe, the method of expression is: nominal diameter refers to the outer diameter (diameter * wall thickness). The unit is mm. [for example, seamless steel tubes of phi 32 * 3. It means that the nominal diameter (outside diameter) is seamless steel pipe of phi 32mm and wall thickness 3mm.
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:What is the difference between seamless steel pipe and welded pipe?
The thicker the diameter, the more commonly the spiral weld. The seamless steel pipe is generally molten state molten steel through the annular slot backlog, and then stretched and other treatment process, so that there is no weld. On the performance, especially the pressure capacity of the steel pipe than ordinary steel has greatly improved, so often used for high voltage equipment.
Q:How to distinguish between steel pipe and spiral pipe material?
Steel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.
Q:What does "HBB" glass steel pipe mean?
Non electrical corrosion, non-magnetic, suitable for single core cable laying, and steel pipe is a magnetic material, special treatment must be taken to prevent the formation of eddy currents.
Q:What does "1.5" steel tube mean?
This is neither an outer diameter nor an inner diameter; it should be related to an English unit at the beginning of the pipeline development; it is usually used to describe galvanized steel pipes; it corresponds to the English units as follows:4, in charge of: 4/8 inches: DN15;• 6 in charge: 6/8 inches: DN20;• 1 inch tube: 1 inches: DN25;• inch two tubes: 1 and 1/4 inches: DN32;• inch half tube: 1 and 1/2 inches: DN40;- inch tube: 2 inches: DN50;• three inch tube: 3 inches: DN80• four inch tube: 4 inches: DN100;
