Single hydraulic prop pipe, in accordance with standard GB / T17396-2009. It is mainly used to make coal mine hydraulic supports and cylinders and columns, as well as other hydraulic cylinders and columns.The single hydraulic prop tube is made of 20, 45, 27SiMn and so on.
Heat treatment system: 20 and 45 are normalized; 27SiMn (920 ± 20) ° C water (450 ± 50) ° C tempering, coolant: oil or water.
Single hydraulic prop pipe is based on high-quality carbon structural steel, and one or several alloy elements are appropriately added to improve the strength, toughness and hardenability of steel. After this type of steel is made, it usually requires heat treatment such as quenching and tempering, chemical heat treatment, and surface hardening. Compared with high-quality carbon structural steel, it has good comprehensive mechanical properties. It is often rolled into round, square, flat steel and used as an important structural part in machinery or machinery.
The rust resistance of the single hydraulic prop pipe is not stainless steel itself, of course, the rust resistance is not enough. But wear resistance and machinability are much better than stainless steel.
Calculation method of single hydraulic prop pipe:
Single hydraulic prop pipe
[(Outer diameter-wall thickness) * wall thickness] * 0.02466 = kg / meter (weight per meter)
