Gas Distribution System

Engineered for safety, built for performance

Maintenance and hot work onboard are indispensable to the operation and upkeep of your vessels. With an increasing focus on regulation safety and compliance, it is crucial to make the right choice for your hot work infrastructure. We understand how important this choice is, and our AC/OX Gas Distribution System is the standard for safety in the maritime industry.

Our system is complete with all the safety devices you need for compliance with safety standards such as SIRE 2.0 and RISQ 3.1. We are your trusted supplier of a safe, reliable and compliant Gas Distribution System that ensures performance like no other.

Built for gas welding safety and compliance

The Unitor Gas Distribution System is a complete solution for your acetylene and oxygen welding and cutting needs. Ensure safer oxy-acetylene operations with quality components and critical safety devices in one complete solution.

Safety

Flashback arrestors, pressure regulators and isolated cylinder storage greatly reduce the risk of accident
Efficiency

Reduce movement of acetylene and oxygen cylinders and interruptions to gas supply
Economy

Oxy-acetylene jobs are done faster with fewer consumables expended

Are you compliant with RISQ 3.1 and SIRE 2.0?

With the latest SIRE 2.0 and RISQ 3.1 questionnaires spotlighting hot work safety, using a compliant system with safety devices like flashback arrestors and pressure regulators onboard your vessel to mitigate safety risks is key.

We help you understand the changing regulations and guidelines and ensure you always stay up to date no matter what comes next.

SIRE 2.0

The rollout for OCIMF SIRE 2.0 has been planned in four phases, with the final rollout happening by 2024. Upon which, all vessel inspections will be conducted with the updated SIRE 2.0 questionnaire. Here's what you need to know to remain compliant for gas welding:

Install flashback arrestors on both torch and gas regulators for long lengths of AC-OX gas hoses.

Ensure the AC-OX gas hoses are in compliance with ISO 3821 / EN 559 and in good condition by performing bend test and visual inspection.

Ensure good safety practices by purging all remaining gases in-line and keeping the gas equipment and cylinder valves closed after completion of the work.

Ensure all Personal Protective Equipment (PPE) for Gas Welding and Cutting use is well maintained.

Ensure signages and safety posters are available, especially “No Smoking” sign

RISQ 3.1

The updated RightShip RISQ 3.1 questionnaire highlights the importance of pressure regulators and flashback arrestors in preventing gas-related accidents onboard, and has been recently updated with new guidelines on equipment use to further improve safety. Here's what you need to know:

Inspect pressure regulators and flashback arrestors annually, and ensure all inspection data has been logged

Replace pressure regulators and flashback arrestors every five years from the manufacturing date.

All acetylene and oxygen GDS piping should be colour-coded accordingly, ie., blue for oxygen, red for acetylene.

Twin gas hoses should be crimp-fitted or fitted with "Clamp 1 Ear" type clamps at all joints.

A non-return valve or flashback arrestor must be fitted before the torch connection.

Pressure testing of on board piping system should be performed by a competent person in accordance with applicable CLASS/FLAG rules. An appropriate certificate or service record should be issued.

Key Safety Features

Flashback arrestors

Built to respond to dangerous levels of pressure and temperature, the Flashback arrestor prevents a flashback from travelling upstream and reaching your cylinders, protecting your vessel and crew from accidents.

T-valves with non-return valves

Allows for connection of multiple cylinders, ensuring a more reliable gas supply and efficient workflow. The non-return valve also prevents backflow of gas into the cylinder.

Closing valves

Closing valves are a crucial component in the GDS, allowing for isolation of the gas supply in case of accidents.

Primary regulators

Outfitted with large adjustment knobs clearly colour coded for easy identification, our primary regulators are equipped with a safety valve outlet and anti-tampering measures for your safety.

Click here
Secondary regulators

The secondary regulator provides a constant flow of gas at a safe working pressure fit for various AC-OX hot work applications.
