The flame arresters supplied by DCM are based on construction principles that have been tried and tested for decades and are constantly being adapted to the state of the art. Cast and welded constructions enable a large number of material variants as well as adaptation to special connection requests or other special solutions for our customers. Flame arresters as the heart of the flame arrestors can be manufactured in a wide variety of designs. This also fulfils the special requirements of OEM manufacturers of special equipment in explosion protection.
Our Flame arrestors include in-line detonation arrestors and end of line detonation
See products below for more detail.
For installation into pipes to the protection of vessels and components against stable detonation of flammable liquids and gases. Tested and approved as detonation flame arrester type 4. Approved for all substances of explosion groups IIA1 to IIB3 with a maximum experimental safe gap (MESG) ≥ 0.65 mm . Bi-directionally working in pipes, whereby an operating pressure of 1.2 bar abs. and an operating temperature of 60°C must not be exceeded. The installation of the detonation flame arrester into horizontal and vertical pipes is permissible. Provided with one or two temperature sensors (PT 100) the armature is certified against short time burning from one or both sides. If only one thermal sensor is attached, it must be installed into that part of the body from which a fire is expected.
As breather/venting safety device incorporating an explosion proof flame arrester element for installation on top of storage tanks, tank access covers or breather pipes. The breather allows the unimpeded flow of gases out to atmosphere and air into the tank/pipe thereby preventing vacuum locks whilst ensuring provision of a permanent and reliable protection against any flashback into the tank/pipe. This device is not permitted to be installed in enclosed areas.
Approved for all materials of the explosion group IIB3 with a maximum experimental safe gap (MESG) ≥ 0.65.
