The gasket torque formula is crucial for calculating the torque required to properly seal gaskets in mechanical assemblies, such as in engines and piping systems.

Gasket Torque, Tg(N.m) in Newton metres, is determined by multiplying the force, F(N), applied in Newtons, by the nominal diameter of the bolt or stud, D(mm), in millimetres, and by the gasket factor, k, which accounts for the type of gasket material and its properties. The product is then divided by 1000 to convert the torque into Newton metres.

Gasket Torque, Tg(N.m) = (F(N) * D(mm) * k) / 1000

Tg(N.m) = gasket torque in Newton metres, N.m.

F(N) = force in Newton, N.

D(mm) = nominal diameter in millimetre, mm.

1. To achieve an optimal seal, a force of 10,000N is required on a gasket sandwiched by a bolt of nominal diameter 10mm. The gasket material requires a factor (k) of 0.25. Determine the torque needed to apply this force.

Given: F(N) = 10,000N, D(mm) = 10mm, k = 0.25.

Gasket Torque, Tg(N.m) = (F(N) * D(mm) * k) / 1000

Tg(N.m) = (10000 * 10 * 0.25) / 1000

Tg(N.m) = 25N.m.

2. A required torque is 80N.m to properly seal a metal gasket with a bolt of 20mm nominal diameter. The gasket factor for this type of gasket is 0.2. Calculate the force needed to apply.

Given: D(mm) = 20mm, k = 0.2, Tg(N.m) = 80N.m.

Gasket Torque, Tg(N.m) = (F(N) * D(mm) * k) / 1000

F(N) = Tg(N.m) * 1000 / D(mm) * k

F(N) = 80 * 1000 / 20 * 0.2

F(N) = 20,000N.
