Branches and Repairs in XL Saddle area with sealing and heating coil The assembly of branches for HD-PE pipings up to d 1000 has hitherto required great efforts. Usually, one T-piece as well as three couplers are used. The handling is difficult and much space is required. Any subsequent installation also requires comprehensive underground work and shutting off. With FRIALEN spigot saddles SA-XL, branches at large pipes are prepared much more easier. Simply position on the pipe at the prepared place. Pre-mount under vacuum using the clamping tool VACUSET XL. Fuse and leave to cool. Prepare the branch with the drilling equipment FWAB XL. For any subsequent installation, only a head access hole is required. Fusion and tapping (using a shut-off valve) can be made under operating pressure. For repairs of damages in large HD-PE pipes repair saddles RS-XL are available which are also pre-mounted under vacuum.
