Oxygen-Fuel Gas Welding and Cutting - Service Pipe Systems |

|
Now that we understand material and design requirements, let’s consider
the installation of a service pipe system. All piping shall be run as directly as practical. It will be protected against physical damage with proper allowance for expansion, contraction, jarring, and vibration. Pipe laid underground in earth shall be located below the frost line and protected against corrosion. After assembly, piping shall be thoroughly blown out with air, nitrogen, or carbon dioxide to remove foreign materials. For oxygen piping, only oil-free air, oil-free nitrogen, or oil-free carbon dioxide shall be used. |
