2.4.1 Termination at the storage tank Termination of the secondary con- tainment piping system at the storage tank is accomplished using a termi- nation fitting with 3/4" female NPT threaded outlet (See Figure 2.4.1). The 3/4" threaded outlet allows easy access for pressure testing of the sec- ondary containment piping system and may also be used as an access for a leak detection probe.

To facilitate ease of terminat- ing, special bell x male adapters or special sleeve couplings for second- ary containment (which have been machined to fit the secondary con- PPP_ 0.01A 110 go CGLASS tainment fittings) are available for use with secondary containment ter- mination fittings. If machined bell x male adapters are notavailable, stan- dard male threaded adapters orsleeve couplings may be used (See Table 2.4.1).
