New from James Walker is the Supagraf Boilermaster braided ribbon gasket, which is designed to seal boiler doors at high temperatures and offer resistance to oxidation and chemical attack plus significantly reduced maintenance costs.
Boilermaster can be used with confidence at steam temperatures to 230°C, which equates to a saturated steam pressure of 27 bar. It may be suitable for higher temperatures and pressures following consultation with the manufacturers.
Simple to install and remove, Boilermaster gaskets are flexible and deformable for ease of fitting, and are compressible enough to ensure that uneven mating surfaces are completely sealed. They are easy to remove and replace for boiler servicing, without the need for any chiselling.
They are available as endless joints to fit hand-holes and man-ways, in elliptical, oval, obround and circular shapes from 45 mm to 610 mm inside diameter and in flange widths from 9.5 mm to 50 mm. All standard joints are 6.5 mm thick. Sizes outside these dimensions may be supplied.
The graphite ribbon is resistant to 450°C in an air/oxidising environment. It offers excellent chemical resistance across the range from 0 to 14 pH and has a low content of corrosion initiator impurities such as chloride and sulphur.
