Until you become familiar with the contents of a Spec, you may want to review them to verify that they match the requirements of your job.
Double click onSAMPLE Copper -2″ /Weld-above. The Spec screen appears. NOTE: Spec screens consist of database items that define which type of pipe, fittings, valves, etc., will be used in a piping system.
