AS4839-2001GUIDANCE ON MAINTENANCE (Table 1)

This guide outlines the maintenance of welding equipment. Regulators require biannual testing by a qualified person.

- Flashback arrestors and other devices need yearly checks or post-flashback inspections, with a five-year replacement guideline.
- Hose assemblies demand biannual checks for wear and tear, and a five-year replacement schedule.
- Blowpipes, mixers, and attachments should be inspected weekly or before use, with replacements every five years or as recommended.

Equipment Weekly (if in constant use) or before every use (to be per-formed by the operator)As nominated (to be carried out by a technically competent person)Refurbishment or replacement intervals (equipment condition determines whether refurbishment) 1. Regulators (including their integral protective devices) According to the manufacturers instructions including — visual examination to determine suitability for service (e.g. gas, pressure rating, damage); condition of threads and sealing surfaces; and oil or grease contamination. Leak test all joints at working pressure.Six monthly: Functional tests to ensure the correct operation of internal componentsManufacturer or supplier recommendation, but not exceeding five years.* 2. Flashback arrestors and other external devices (including non-return valves) Visual examination to determine suitability for service (e.g. gas, pressure rating, damage); condition of threads and sealing surfaces; and oil or grease contamination. Leak test all joints at working pressure. Yearly as detailed in AS 4603 or following a flashback: Proper functioning of the non-return valves and flashback arrestors. For pressure-activated valves, check there is no flow in the normal direction with the valve tripped. Manufacturer or supplier recommendation, but not exceeding five years.* 3. Hose assemblies Visual examination to determine suitability for service (e.g. gas, pressure rating, damage); condition of cover; and threads and sealing surfaces of the end fttings. Leak test all joints at working pressure. Six monthly: Check for absence of cuts and excessive wear by bending the hose in a tight radius, to ensure reinforcement is not visible Determined by the hose assembly condition. 4. Blowpipes, mixers and at-tachments Visual examination for damage of the threads and sealing surfaces of the hose connections and the attachment connections. Leak test all joints at working pressure. Six monthly: Test control valve function. Blank the attachment connection and leak test for internamal-function. Manufacturer or supplier recommendation, but not exceeding five years.*

* Regulator elastomers and seals will wear and deteriorate in service and deteriorate out of service. Items stored for one year or over without use should receive inspection as per the annual maintenance inspection
