Key Features of Draper Flash Back Arresters

Draper flashback arresters incorporate several important features that ensure reliable protection in oxy-fuel applications. The devices typically feature a flame trap element constructed from sintered metal or special alloy materials that can withstand extreme temperatures whilst stopping flame propagation. This critical component acts as a barrier that prevents flame from travelling backwards through the system whilst maintaining efficient gas flow during normal operation.

The internal mechanism includes non-return valves that respond instantly to reverse gas flow, shutting off supply before dangerous pressure can build or flame can reach cylinders or regulators. Many Draper flashback arresters feature thermal cut-off mechanisms that provide an additional layer of protection by permanently closing if excessive heat is detected, indicating a flashback event has occurred. This thermal fuse functionality prevents the device from being used after a flashback incident until it has been properly inspected or replaced.

Construction quality is evident in the robust brass or steel housings used throughout the Draper range, providing durability and resistance to workshop knocks whilst maintaining gas-tight integrity. Standard connection threads ensure compatibility with commonly used regulators, hoses, and torches, making installation straightforward. Clear directional markings and colour coding help prevent incorrect installation, whilst some models feature visual indicators that show when the device has activated and requires replacement.

Popular Draper Flash Back Arresters

Available from Tooled-Up, Draper's flashback arrester range includes devices designed for different positions within oxy-fuel systems. Cylinder-mounted flashback arresters install directly at the regulator outlet, providing first-line protection closest to the gas source. These units offer the highest level of protection by preventing any flashback from entering the cylinder or regulator assembly, making them the preferred choice for comprehensive safety systems.

Torch-mounted flashback arresters fit between the hose and cutting or welding torch, providing additional protection at the point of use. These compact units are particularly valued in situations where hose length or working conditions increase flashback risk. Many professional setups use both cylinder-mounted and torch-mounted arresters for redundant protection.

Draper also offers inline flashback arresters designed for mid-hose installation, useful for upgrading existing systems or providing protection on extended hose runs. Gas-specific models ensure appropriate protection for oxygen, acetylene, propane, and other fuel gases, with clear identification to prevent cross-connection errors.

Safety and Compliance

Flashback arresters are not just recommended safety equipment – they're essential protective devices that should be considered mandatory for any oxy-fuel welding or cutting operation. The Health and Safety Executive (HSE) provides clear guidance on the use of flashback protection in welding operations, and properly specified arresters help workshops comply with these requirements whilst protecting against potential insurance complications in the event of an incident.

Draper flashback arresters are manufactured to comply with relevant British and European standards, including ISO 5175 specifications for safety devices. Regular inspection and maintenance of flashback arresters is crucial, as these devices can be damaged by flashback events, contamination, or general wear. Any flashback arrester that has activated its thermal cut-off should be immediately replaced, not reset or reused. Similarly, devices showing signs of damage, contamination, or age-related degradation should be replaced promptly.

Proper installation is critical for effective protection. Arresters must be installed in the correct flow direction, with arrows or markings clearly indicating proper orientation. Connection threads should be checked for damage and correctly tightened to prevent leaks, and devices should be positioned where they won't be subjected to excessive mechanical stress or damage. Regular leak testing using approved methods helps ensure system integrity and safe operation.

Frequently Asked Questions

Where should Draper flashback arresters be fitted in my welding setup?

For optimal protection, fit flashback arresters at both the regulator outlet (cylinder-mounted) and at the torch inlet (torch-mounted). This dual protection approach provides redundancy and ensures comprehensive safety. At minimum, cylinder-mounted arresters should be used on both oxygen and fuel gas lines to protect the most critical and expensive components of your system.

How often should flashback arresters be replaced?

Flashback arresters should be replaced immediately if they activate their thermal cut-off mechanism, which indicates they've experienced a flashback event. Even without activation, manufacturers typically recommend inspection every 12 months and replacement if any damage, contamination, or wear is evident. Some professionals working in demanding environments replace arresters annually as preventative maintenance regardless of condition.

Are Draper flashback arresters suitable for professional daily use?

Yes, Draper flashback arresters are designed for professional workshop applications and can withstand the demands of daily use when properly maintained. They meet relevant safety standards and provide reliable protection suitable for commercial welding operations. The robust construction and quality components ensure dependable performance in busy workshop environments.

Can flashback arresters restrict gas flow and affect welding performance?

Properly specified and maintained flashback arresters have minimal impact on gas flow rates and should not noticeably affect welding or cutting performance. However, contaminated or partially blocked arresters can restrict flow, which is why regular inspection and timely replacement is important. Always ensure arresters are appropriately rated for your torch and gas consumption requirements.

Do I need different flashback arresters for oxygen and fuel gases?

Yes, flashback arresters are gas-specific and designed for either oxygen or fuel gas (acetylene, propane, etc.) applications. They are typically colour-coded and marked to prevent incorrect installation – oxygen arresters are usually blue or have blue markings, whilst fuel gas arresters are red. Never use an arrester with a different gas than it's designed for, as this can compromise safety and effectiveness.
