Flameless Explosion Venting

Product Introduction:

Flameless explosion venting primarily consists of a vent panel and a flame arrester. When an explosion occurs, the vent panel immediately opens to release pressure. As the fireball passes through the open vent panel, the flame arrester extinguishes the flames and reduces the temperature of the hot gases. It is typically used for indoor explosion venting where venting is not possible to a safe outdoor area. It protects the integrity of the equipment and reduces the risk of secondary explosions.

Application Scenario

Core Products

Aluminum Powder Classifier Milling System

Aluminum Powder Classifier Milling system is an innovative device that integrates dry milling and dynamic classification of materials.

Ball Mill

Ball mill is the key equipment for crushing materials after they are broken. The cylinder is generally made of welded steel plates, closed at both ends with end covers, and the inner wall of the cylinder is inlaid with wear-resistant lining to prevent the cylinder from wear.

Explosion Isolation Flap Valve

The explosion-proof flap valve is a pressure differential self-operated dust explosion isolation valve that does not require external electrical equipment.
