This is VIQ requirement: VIQ 5.26 Is gas welding and burning equipment in good order and spare oxygen and acetylene cylinders stored apart in a well-ventilated location outside of the accommodation and engine room? Piping should be of steel welded construction and bolted flanges are prohibited. Copper, rubber or braided lines should not be used, except that braided lines may be used for the short length from the cylinder heads to the manifolds within the storage space. Pipework and fittings should be free of grease. Pipe joints on the low-pressure side of the regulators shall be welded. (46 CFR 56.50-103) Note. In open air locations it may be acceptable for a short length
Would appreciate if you can provide me with photos to see the right disposal of piping (material of piping) to be used.

No bolted connections, all pipes are made of steel except braided lines for connecting of cylinders.
