Info

When you receive such fittings from vendors, mark each fitting with positive markings for future identifica- tion. (The vendor should have already marked the fittings for you). Do not s<strong>to</strong>re altered fittings with regular sized fittings. A wrong fitting installed by accident in a system could prove disastrous. Backing Rings Figure 2-16 shows rings that are sometimes used in piping systems under severe service conditions. One type ring is grooved with knockoff spacer pins. Figure 2-16.

Figure 2-17. Flat type and ridge type welding rings. (Courtesy of Tube Turns Tech- nologies, Inc.) The backup rings are inserted in the adjoining ends of pipes that are <strong>to</strong> be buttwelded. The rings prevent spat- ter and metal icicles from forming inside the pipe. The ring becomes a permanent part of the piping system. Figure 2-17 shows two other type backing rings--the flat and ridge types. Branch Olet Connections There are many reputable manufacturers of Olet fittings used for branch connections. For description and illustration purposes, the Bonney Forge fittings are de- scribed here, along with their registered trade names for the fittings. Interchangeability Table 2-2 shows the interchangeability and size con- solidation of the Olet fittings. The correct descriptions of 57
