Westech Flame Arresters

Westech Industrial has been working in the petrochemical industry for over 50 years and is a leading manufacturer of Inline Deflagration and Detonation Flame Arresters. The equipment quenches flame propagation through independent passive operation and allows for free vapour flow. There is a growing need for this product to reduce emissions of VOC’s (volatile organic compounds) into the atmosphere. This environmental benefit is achieved through flaring, incinerating or recovering the vapour.


Tested in Excess of Existing Standards, complete testing through the “Flame Profile Curve”.  All Westech arresters are tested for actual field conditions not mandated by existing standards, including momentum impulse (long-run stable detonation), thermal failure and reignition of downstream unburned gases providing maximum protection against all modes of flame propagation.

Research & Design

Unrivalled Research & Design.  Westech developed the test method “A Comprehensive Test Method for In-Line Flame Arresters”, that has been used as the cornerstone for all existing detonation arrester standards.

Customer Service

Superior Customer Service.  Through the years Westech has earned an excellent reputation worldwide for customer service before, during, and after the order.
