u leg of the 45° containment elbow and the side outlet run of the containment tee. Refer to Table 2.3.1 for the maximum length that can be removed and for the minimum nipple length of both product piping and secondary containment piping. To prevent interference of the pipelines, do not locate two containment fittings closer than shown in Table 2.3.2, Fig. 2.3.1. the Storage Tank SECTION 4 Pkermination Connections 2.4.2 Termination at the Dispenser Termination of the secondary containment piping system at the dispenser is accomplished using a termination fit- ting with or without the %" NPT threaded outlet (see Fig. 2.4.2). To facilitate ease of terminating, special bell x male adapters or special sleeve couplings for secondary contain- ment are available for use with secondary containment termination fittings. The special adapters and sleeve cou- plings have been machined on the O.D. to fit the sec- ondary containment termination fittings. If machined bell x male adapters are not available, standard male threaded adapters or sleeve couplings may be used (see Table 2.4.1). Non -machined surfaces must be sanded to fit the secondary containment fittings (see Fig. 2.4.3). "n of the secondary containment piping system " forage tank is accomplished using a termination 2.4.3 Termination Fittings (See Table 2.4.1) R ding with %" female NPT threaded outlet (see Fig. 2.4.1). The X" threaded outlet allows easy access for pressure test- ing of the secondary containment piping system, and may also be used as an access for a leak detection probe.

If there is a gap between the fitting halves when assembled by hand, pipe must be scarfed more. FIGURE 2.4.3 Note: Termination fittings will not work with bell x female threaded adapters. rings 10 25
