Function and Description

High-Tech Coating of the Housing

The In-Line Detonation Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). Flame Arresters Apagallamas 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 Carcasa 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 Revestimiento 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 Amortiguador 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).

Main Component – PROTEGO® Flame Arrester Unit

The devices are symmetrical and offer bidirectional flame arresting for deflagrations and stable detonations. The arrester essentially consists of two coated housing parts (4), two coated shock absorbers and the PROTEGO® Flame Arrester Unit (2) in the center. The PROTEGO® Flame Arrester Unit is modular and consists of several FLAMEFILTER® discs and spacers firmly held in a FLAMEFILTER® cage Carcasa del elemento apagallamas The FLAMEFILTER® cage is a housing for a FLAMEFILTER® set. . The number of FLAMEFILTER® discs and their gap size depends on the arrester‘s conditions of use.
