Remove drilling machine andadapter from gate valve as a unit.J–Placing By-Pass Line InOperation1. If integral by-pass line is beingused between two stopping machines(Fig. L), place the line in operation by:a) Remove the plug from teein equalizing line, then openupstream stopping machine gatevalve slightlyb) Open upper valve in equalizing lineuntil all air is purged from by-passline through the open tee. Closethe upper valve and pressure willbuild up in the by-pass line.c) Open both stopping machine gatevalves fully. By-pass line is now inoperation.2. If separate by-pass line is beingused around the two stoppingmachines (J.), place the line inoperation by:a) Remove the plug from tee inequalizing line, then open gatevalve on up stream by-passconnection.b) Open upper valve in equalizing lineuntil all air is purged from by-passline through the open tee. Closeupper valve in equalizing line andpressure will build up in the bypass line.c) Open gate valve on downstreamby pass connection. By-pass line isnow in operation.12. Continue drilling until hole isdrilled. This can be determined by feelof feeding mechanism, the pull on theratchet handle or by measuring theadvance of the boring bar.73. If H-17160 or H-17161 Bottom-OutFittings and bottom-out line is beingused, (Fig. K), the bottom-out line isthe by-pass line and was alreadyplaced in operation during the drillingout of the pipe.4. If using one stopping machine tostop -off the pipe, (Fig. L), purge the airfrom the equalizing line by:a) Remove plug from tee inequalizing line, then open stoppingmachine gate valve slightly.b) Open upper valve in equalizingline until all air is purged from theequalizing line through the opentee. Close the upper valve andpressure will build up in equalizingline.c) Replace plug in tee in equalizingline.K–Insert Stopper Into Fitting1. Turn the T-handle on the topof the stopping machine so thatthe arm with the arrow having theword “Stopped” on it points towardthe section of pipe to be stoppedoff. (When using by-pass rubberstoppers, this locates the by-pass onthe stopper in the proper position.)2. Open stopping machine gate valveand advance inserting bar of stoppingmachine until the rubber stoppercontacts the bottom of the fitting. Donot rotate T-handle.3. Hold inserting bar in this positionby placing yoke of the machine in thecollar of the inserting bar (Fig. H).L–Expand Stopper In Fitting1. Turn feed nut and yoke of stoppingmachine clockwise a little at a timewith a short pause after each turn.! CAUTION: Do not rotateT-handle. Continue to compressthe stopper in this manner untilthe line is stopped-off. This maybe tested by use of the purgingconnection or any other openingthat may be avail able in the sectionof pipe that is stopped off.
Line Stopper Unit No. 1TMInstructions for Installing and Stopping-Off 1” – 2 1/2” Line Stopper FittingsNOTE: Unnecessary damage canbe done to the stopper by toomuch compression, therefore,we recommend not compressingthe 11/2” and 2” stoppers morethan 1”. The amount the stoppersare compressed can be easilydetermined by measuring thedownward travel of the insertingbar.2. With both stoppers expanded,open the gate valve on a savea-valve drilling nipple used as apurging connection to blow down thestopped-off section of pipe. Stoppertightness will also be indicated at thispoint.3. Proceed with the work to be doneon the stopped-off section of pipe.4. When cutting or welding near linestop per fittings containing rubberstoppers, it is recommended thatthe minimum distance between theface of the stopper and the cutting orwelding operation be as follows:Size of FittingMinimum Distance1”, 11/4”6”11 /2 ”7”2”8”2 1 /2 ”9”Where it is not possible to maintainthis minimum distance, other coolingmeans such as wet burlap or wetrags, should be placed aroundthe fitting to keep the temperaturedown.5. When using H-17160 or H-17161Bot tom-Out Fittings, cut out theisolated section of pipe and weldcaps to the stubs.M–Contract Stopper In Fitting1. When all desired work has beendone on the stopped-off section ofpipe, check to be sure all weldedjoints are cool be fore proceeding.2. Replace plug in tee in equalizingline.4. Open the gate valve on purgingconnection until all air is purgedfrom the stopped-off section. Closepurging connection gate valve.5. Test all joints when pressure hasbuilt up in section that was stoppedoff.4. When using a separate by-passline around two stopping machines,close gate valves on upstream anddown stream by-pass connections,remove plug from tee in equalizingline and open upper equalizing valveto blow down by-pass line.6. The pressure must be equal onboth sides of the stopper beforecontracting and removing the stopperfrom the fit ting. Contract stoppers byturning feed nut and yoke of stoppingmachine counter-clockwise a littleat a time with a short pause aftereach turn until stoppers are fullyreleased. The number of turns tocontract stoppers will usually be thesame as used to compress stop pers.5. When using one stopping machineto stop-off the pipe, blow down theequalizing line by closing lower valveon equalizing line, remove plug in teeand open upper equalizing valve.NOTE: When using the H-17160 orH-17161 Bottom-Out Fittings andspecial by-pass rubber stoppers,the stoppers con be contractedwithout equalizing line.
