I&M008-10223_USER_layout 6/17/14 3:27 PM Page 8 Type 81 Bolt-Thru (Installed View) Prior to installation, please follow the recommended manufacturer procedure: A. Confirm process has been shut down with process pressure relieved and piping drained. B. Provide pipe flange gasketing, mounting bolts, lockwashers and nuts (not supplied by Ashcroft). Step 1: Isolation ring and flange gaskets should be centered between process piping flanges.
I&M008-10223_USER_layout 6/17/14 3:27 PM Page 9 Step 3: Tighten the piping flange bolts to the locking nuts / washers on the opposite flange. Each should be tightened by cross-bolting with the proper torque based as described in ASME PCC-1 on NPS, ANSI/ASME Class rating, and gasketing used.
I&M008-10223_USER_layout 6/17/14 3:27 PM Page 10 C. Loosen flange bolts securing the isolation ring assembly to the process pipe flange. D. Upon separation of pipe flanges, remove assembly and flange gaskets from the piping. In the event only instrument removal is required, use a wrench to unthread the instrument. Use container to catch the fill fluid when draining from the isolation ring.
