| Re: What cylinder characteristics are preferred If you guys are applying for exemptions to start with why not just go with a steel with a higher tensile strength like used in the UK.. The cylinders are lighter and are rated for higher pressures..
This is exactly what I'm planning. An exempt cylinder at 3442 psi, the metallurgy is similar to high strength European models. 3 liter cylinders will hold 25 cf of gas-hot dip galvanized finish. |
