According to the wall thickness, it can be divided into thin-walled type and thick-walled type. Thin wall type cylinder tube is mainly used for mini pneumatic cylinder, full stainless steel air cylinders and other series. The thick-walled is mainly used for hydraulic cylinders which need to withstand high pressure.
According to the material, it can be divided into SUS304, SUS316, etc. Generally, the default stainless steel material is SUS304, which can take into account the aspects of hardness, strength and cost.
Characteristics of stainless steel cylinder tube
◆ Corrosion resistance, Rustless forever
◆ With high strength resistance, wear resistance and
◆ Long service life
◆ Support customization
◆ High roundness
The relationship between the wall thickness of a stainless steel cylinder tube and theoretical Maximum allowable working pressure
The stainless steel cylinder bears the thrust force from the side. Usually, the thicker the wall thickness of the cylinder, the bigger the pressure the cylinder can withstand.
Of course, NOT the larger the wall thickness is, the better. Excessive cylinder wall thickness will greatly increase the cost and weight of the product, and it will be also more difficult to process. Here is a simple formula for converting wall thickness to maximum allowable working pressure.
P = δ*2*300/(d - δ*2)
P: Theoretical Maximum allowable pressure MPa
δ: Wall thickness mm
d: Cylinder inner diameter mm
E.g.: The inner diameter of a cylinder tube is 125mm, and the wall thickness is 5mm, then the theoretical Maximum allowable pressure would be:
P = 5*2*300/(125 - 5*2) = 3000/115 ≈ 26.1MPa
Considering the security coefficient 4 times, the real Maximum working pressure should be less than
26.1MPa / 4 ≈ 6.52MPa
