Unit 8 - Introduction to piping and tubing systems


There are various types of piping and tubing systems used for gas. A thorough knowledge of these systems, as well as the associated valves and fittings, is necessary in order to properly plan for and install a piping or tubing system.

Correctly sizing the piping and tubing system supply piping depends on many factors: the length of the pipe, the supply pressure, any changes in direction of the pipe, etc. Installation requirements also depend on the location, i.e., whether the piping or tubing system is installed underground, above ground, on a rooftop, etc. Whenever installing piping and tubing systems, they must be tested and inspected to ensure they meet the Code requirements.

  • Describe piping and tubing systems.
