5. Theoretical Weight and Pressure Resistance Performance

Note: 1. Considering safety factors, the working pressure is one-quarter of the hydrostatic test pressure. For 6063 alloy, the yield strength is 145 MPa; for 3A21 alloy, it is 135 MPa; and for pure aluminum, it is 85 MPa. 2. When converting to the old unit kg/cm², multiply the above values by 9.8. The above data are valid at room temperature. At 150°C, the value is approximately 90% of that at room temperature.
