- Consumables
- Article
Supplying gas to your metalworking applications can be complicated, especially if the gas needs to reach multiple locations. If you are looking for cost savings and productivity gains, consider installing gas cylinders at one main location and controlling them with a basic manifold or switchover manifold. With this method you won’t need to worry about cylinders running out of gas.

Wading through the NFPA-51 standard
- By John Karpus
- Jan 17, 2011
- Safety
- Article
The NFPA-51 standard outlines how to properly store, transfer, and use industrial gases; how to handle such gases while they are in their gaseous or liquid phases; and how to implement storage, piping and distribution, and operating practices. While most safe practices are based on common sense, others may take volumes of technical reference, as specified in NFPA-51, to explain.
