Function and Description

Efficient Flow Performance

In the development of the PROTEGO® FA-I in-line deflagration flame arrester In-line deflagration flame arrester A deflagration flame arrester is designed to prevent the transmission of a deflagration. An in-line deflagration flame arrester is equipped with a pipe connection on both sides. , special effort was made to optimize the fluid dynamic flow characteristics. For a given flange connection size of the flame arrester, the FLAMEFILTER® size can be chosen for the most adequate flow capacity. When installing the deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). flame arrester, make sure that the distance between potential ignition sources and location of the installed device does not exceed the L/D ratio (pipe length/pipe diameter) for which the device was tested (see table 4).

Main component - PROTEGO® flame arrester

The deflagration flame arrester is symmetrical and offers bidirectional flame transmission protection. The device essentially consists of two housing Housing A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. parts (1) and the PROTEGO® flame arrester unit PROTEGO® flame arrester unit The PROTEGO® flame arrester unit is the main component of a flame arrester. It prevents flame propagation. (2) in the center. The PROTEGO® flame arrester unit is modular and consists of several FLAMEFILTER® discs (3) and spacers firmly held in a FLAMEFILTER® casing FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. . The number of FLAMEFILTER® discs and their gap size depends on the arrester´s intended use.

For Explosion groups IIA to IIB3

Specifying the operating conditions, such as the temperature, pressure, explosion group, and the composition of the fluid, enables PROTEGO® to select the best deflagration flame arrester for your application. The PROTEGO® FA-I series of deflagration flame arresters Deflagration flame arrester Flame arrester designed to prevent the transmission of a deflagration. It can be an end-of-line flame arrester or an in-line flame arrester. is available for substances of explosion groups IIA and IIB3 (NEC groups D and C (MESG ≥ 0.65 mm)).

Many Individual Certifications

The standard design can be used with an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of up to +60°C / 140°F and an absolute operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. up to 1.1 bar / 15.9 psi. Devices with special approvals for higher pressures (see table 3) and higher temperatures are available upon request. EU conformity according to the currently valid ATEX directive.

Dimensions

To select nominal width/ nominal size Nominal size 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/DN) - combination, please use the flow capacity charts on the following pages. Additional nominal width/nominal size (NG/DN) - combinations for improved flow capacity upon request
