Basic Hot Tapping and Line Stop Process

WeldFit's SureLoc™ line stop fittings are used when the removal of the tapping valve is desirable after the completion of a temporary line stop operation. Once the need for the line stop has ended and the line stop head is removed, the SureLoc blind plug is inserted into the Sureloc fitting flange and locked into place by extending the segments into a groove in the plug. An O-ring is incorporated into the plug in order to create a leak-proof seal. Once the Sureloc blind plug is installed, the tapping equipment can be removed and a blind flange installed to complete the process. If there is a need to reinstall the line stop at a future date, it is normally possible to remove the blind flange and plug, in order to insert the line stop head.
