Minimum wall thickness and distance from an edge
The radial expansion of the Sealing Plug causes the housing material around the plug to deform plastically. A proper minimum wall thickness, or distance from an edge is necessary to optimize the strength of the mechanical connection. The operating hydraulic pressure, thermal cycling, plug type and characteristics of the base metal must all be considered when determining these values. Please contact us for additional information.
The guidelines for a minimum wall thickness or distance from an edge (Wmin) are expressed below. These minimum values produce only slight deformation on the exterior profile of less than 20µm. This does not affect the performance of the Sealing Plug. Using Wmin values less than those recommended can cause overloading of the base material. This can adversely influence the function of the Sealing Plug. Please contact us for additional information.
Wmin Guideline Values
Sealing Plug Diameter:
- d1 ≥ 4mm: Wmin = fmin * d1
- d1 < 4mm: Wmin = fmin * d1 + 0.5mm
