RH Nuttall Limited have the facilities to produce many fabricated parts and hand cut gaskets. On occasions we have customers who require a unique product for prototypes or special one off designs. Intricate shapes, composites or simple designs are all accommodated. With our skilled and experienced work force coupled with our extensive range of machinery RH Nuttall Limited we can offer these parts without the need for sometimes expensive tooling and normally with very quick lead times.
Assembly and Forming
In addition to cut parts RH Nuttall has an in-house assembly and forming facility. Components can be folded, jigged, pinned, riveted and stuck. Many of our customers prefer to take delivery of a finished item which can go straight to the final production line. This simplifies their operations, saving them time and money. We also weigh, count and bag up kits or small numbers of parts for specific purposes, again saving your labour costs.
Graphite Foil Gaskets
RH Nuttall Limited also provide sealing solutions with the manufacture of graphite foil components. Washers, gaskets, and seals are all produced from graphite foil. It is manufactured from high purity, high crystalline natural graphite flakes, which are processed into continuous foil by a special acid and thermal treatment to produce expanded graphite crystals. The expanded graphite crystals are then formed into foil through an extensive calendaring process without any resins and binders.
Graphite foil can be used to provide sealing solutions in pressure, temperature and vibration applications. With graphite foil having a low coefficient of friction and being self-lubricating it further enhances its reputation as a superior sealing material. Furthermore, graphite foil is also an excellent choice for sealing where liquids, gases, and chemicals are apparent.
A popular choice of gasket in the automotive trade as well as petro-chemical industry and boiler trades, graphite foil displays outstanding characteristics including excellent thermal stability and reflectivity.
Moreover, graphite foil has a very good temperature prevail being resistant to low temperature of -200°C and having a maximum operating temperature of 450°C in air, 700°C in steam and 3000°C in inert or reducing environment. With graphite foil also being almost chemically inert coupled with its high purity, it makes this material an ideal sealing solution in nuclear environments. Also available with a stainless steel reinforcement. Please be aware that due to its purity Graphite foil is a very fragile material. Graphite foil also provides a good electrically conductive material.
RH Nuttall supply gaskets in Polyester Wadding (Polywad). This is polyester which has been pressed and slightly melted into place producing a flat wadding. Polyester wadding is also known as Dacron. Polyester Wadding is great for a cheap insulating material, and used by us for shroud linings in coffins.
