How is Welded Pipe joined in NFPA 13R?

Explanation:
The main idea is that welded steel sprinkler pipe is joined by welding. In NFPA 13R, welding is an acceptable method to connect lengths of pipe and fittings, providing a continuous, leak-tight joint for residential sprinkler systems. Because the pipe is welded, you don’t rely on threaded connections, adhesives, or soldered joints for those welded sections. The standard requires that welding be performed properly and inspected, but the method itself is simply to join the pieces by welding. The other options imply methods (threaded joints on welded pipe, adhesive bonding, or soldered joints) that are not how welded pipe is joined in NFPA 13R.
