Transcription

1 Gasket Materials >>> BELPAGRAF API 607 Fire Safe Test Approval Pure expanded mineral graphite laminated. Due the natural characteristics of graphite this is a high quality material with an universal use in high pressure and temperature services. Excellent resistance to steam. Meets most refinery, petrochemical and industrial service requirements for long time periods and a wide range of temperatures. Three different grades are manufactured: BELPAGRAF SL/GL: pure mineral expanded graphite laminate. BELPAGRAF SR/GR: laminate with flat 316/316L stainless steel insert (0.05 mm thick). Recommended for steam applications. BELPAGRAF SE/GE: laminate mechanically bonded to a 316/316L stainless steel tanged insert (0,1 mm thick). Grade for high pressures and temperatures.

3 Gasket Materials >>> New nonasbestos BELPA ACID, COMPRESSED GASKET MATERIAL FOR ACID AND ALKALI SERVICE COMPOSITION Compressed nonasbestos gasket sheet made on the basis of aramid and mineral fibres, combined with inorganic fillers, reinforcing a special rubber formulation. The resulting gasket sheet is recommended for use on a wide range of service conditions with chemical resistance to many products including most of the acids, oils, alkalis and solvents. The product has been designed for use with the acid and alkali media most frequently found in industry. Technical Data. COLOUR Standard sizes (mm) Other upon request Standard thickness (mm).

CREEP DEFORMATION / HOT CREEP TEST Temperature increase Fyesa laboratory Thickness decrease SEPTEMBER 2001 CREEP DEFORMATION: percentage loss of thickness over a specified time under constant load, applied at a specified rate, at a specified temperature. Creep (%) = (loss of thickness under load at a specified time / initial thickness of the sample) x 100 Creep deformation gives an indication of the effect of time and temperature on deformation behaviour of gaskets materials. This parameter also gives an indication about the trend of a gasket material to leak in combination with the variables that also affect to a flanged union
