Gaskets and Sheet Jointings
James Walker manufactures and supplies complete ranges of metallic and semi-metallic joints, gaskets and sheet jointings to suit every industrial application.
In addition, we produce precision-cut flat gaskets to any shape, size and quantity from any sheet material, including our own extensive ranges of jointings.
A vast stock of flange gaskets is held ready for immediate despatch, and we can economically cut non-standard profiles of any complexity within minutes.
Our work at the frontier of sealing technology gives us a clear understanding of the roles that gaskets must play, for example…
If joint faces are absolutely flat and aligned true
If flanges do not distort under load
If loaded bolts do not stretch or relax there is no need for a gasket, because the joint will be perfect
In the real world, such perfection is very expensive to achieve and almost impossible to maintain. Therefore a gasket is the most practical and cost effective way to seal a bolted flange joint.
The problem for designers and maintenance engineers is to select the correct gaskets to ensure the integrity and safe operation of their fluid handling plant.
