DA-SB-PTFE

The In-Line Detonation Flame Arresters Corta-chamas Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. Type PROTEGO® DA-SB-PTFE are the latest generation of Flame Arresters and are distinguished by its unique resistance to adhesive and corrosive media. The use of fluoroplastics as a high-tech housing Corpo A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. coating Revestimento Coating is the application of a firmly adhering layer of shapeless material to the surface of a workpiece. and as solid material for the Flame Arrester element is unique throughout the world. The speed of incoming detonations is highly reduced by the effective shock absorber Amortecedor A shock absorber is a device that reduces the kinetic energy of a detonation. (1) and result in an equal pressure distribution across the FLAMEFILTER® surface. This improves the flame extinction in the narrow gaps of the original PTFEFLAMEFILTER® (3).

The Detonation Arrester PROTEGO® DA-SB-PTFE can be used for explosion Explosão Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. group IIA (NFPA group D). The standard design is approved at an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. up to +60°C / 140°F. The maximum allowable operating pressure Pressão operacional Operating pressure is the pressure existing at normal operating conditions within the system being protected. depends on nominal diameter (DN) and nominal size Dimensão nominal The nominal size is an alphanumeric designation of size for components in a piping system, used for reference purposes, comprising the letters DN followed by a dimensionless integer that is indirectly related to the physical size of the bore or outside diameter of the connections, expessed in millimeters. (NG) and amounts to a maximum of 2.4 bar / 34.8 psi absolute (for DN50 / 2” see table 3). EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
