 Inspection Services
Elmac Technologies® offer a comprehensive inspection service for flame arresters and low pressure venting equipment*. Customers can benefit from low-cost in-situ servicing of their safety equipment, by the acknowledged experts in flame arresters and low pressure venting equipment.
* Low Pressure Venting Equipment includes: pressure relief valves, vacuum relief valves, pressure/vacuum combination valves, tank blanketing valves, safety vents, manways, free vents, and gauge hatches.
Why are inspections required?
Flame arresters and low pressure venting equipment are essential safety items which if not inspected regularly can become blocked or fouled leading to reductions in process efficiency, or worse, a loss of explosion protection.
Flame arresters fitted on storage tanks, that become blocked due to process contaminants or acts of nature (bird nests, bee hives etc.) could lead to storage tank implosion. Low pressure venting equipment with faulty valves could result in uncontrolled vapour release thus leading to the presence of potentially explosive atmospheres and an increased risk of deflagration.
Several other factors may also cause the performance of a device to alter over time including changes in process conditions, increasing corrosion rates in flame arrester elements. It is not unknown for arresters to be accidentally damaged during installation and for that damage to go undetected. By ensuring safety equipment is regularly inspected, operators optimise plant process efficiency, reduce operating costs, and minimise the risk of damage to plant and personnel.
Why are Elmac offering an inspection service?
Elmac are offering an inspection service in response to an increasing requirement from operators who:
- Due to maintenance crew down-sizing, are finding it increasingly difficult to complete maintenance schedules
- Have fewer staff familiar with inspection and maintenance of flame arresters and low pressure venting equipment
- Need assistance in ensuring compliance with the latest regulatory guidelines
- Wish to satisfy the requirements of their insurers
How often are inspections required?
The frequency of inspections depends on the process. Elmac recommend at least one inspection per year or:
- After any explosion or significant process disturbance
- At any sign of increasing pressure drop or flow losses
- In the event of any downstream contamination
- Prior to any change to process design or conditions
Who will carry out the service?
The inspection will be carried out on-site by Elmac's highly trained, qualified and experienced engineers. Coupled with a reputation for outstanding customer service, Elmac are acknowledged as technical experts in flame arresting and low pressure venting equipment. Since the 1940's Elmac have accumulated considerable experience of the complexities associated with the design, installation and operation of these types of safety equipment around the world.
What will an inspection include?
An Elmac inspection consists of the following stages:
- Risk assessment
- Dismantle equipment (if required)
