PROCEDURE BULLETIN TEXAS CITY PLAN; HOT TAPPING AND PLUGGING PROCEDURE I. PURPOSE This procedure outlines planning and job preparation requirements for safe hot taps and line plugs performed at Texas City. II. SCOPE .* * ' '.T.'-'V V'i Hot tapping and/or line plugging is a last resort for connection or isolating a piece of equipment or piping system. This procedure covers all hot tapping and/or plugging, including valve bonnet tapping on process or utility systems. Valve packing by tapping and injecting is not included. III. PROCEDURE . . Introduction > . '' * - : '.'Vv', L 'Sf/i >' ' v ! Hot taps and hot line plugs are permissible only when the'time required or expense of isolation and decontamination is unreasonable. A special permit ' ^is required according to Procedure Bulletin P-0117 - Fire, Entry and Special^--.. '/'^PeEmit''Procedure.

Special con- ; sideration must be given to testing media regarding run pipe wall tempera ture and thickness. The Design Engineer,will complete Section II of the i. The" MMTS representative will review and determine materials of construction, hot tap -location, and wall thickness. MMTS will also specify the welding procedure. The Design Engineer and MMTS Engineer will make joint decisions concerning x-raying of the hot tap valve and any other special testing or inspection procedure. The MMTS representative will complete Section^II of the Attachment. : .TL- , / *. .-T - "Si, ' ' 'v:~" ' ~ ORIGINAL ISSUE-* 4/ii/so REVISED: PAGEi_OF_L i /vi\nn06855 PROCEDURE BULLETIN--texas city plant HOT TAPPING AND PLUGGING PROCEDURE p~141 Maintenance :( - The Maintenance Foreman will contact the appropriate Maintenance Zone .^.Engineer for engineering assistance required per this procedure.
