Requirements6.1 The syste

32、m shall be supplied in coil form. Carrier-pipe,thermal-insulation, and protective-jacket material shall be con-tinuous and uniform throughout the coil. Connections andjoints in the carrier pipe and the protective jacket shall not beallowed within the coil.6.2 End Seals:6.2.1 End seals shall be insta

34、 being applied to heat-shrinkmaterials during installation.6.3 Outer Jacket:6.3.1 The outer jacket diameter shall be determined bymeasuring the outside diameter of the jacket. In the case ofcorrugated jacket, the outside diameter of the corrugation shallbe measured.6.3.2 The outer jacket thickness s

The pullingcable shall be installed in the cable tray and att

42、ached to themandrel. The cable is pulled by a winch, causing the rotatingbending-mandrel to turn.

43、 cell shall be calibrated and certified accurateto within 0.5 weight percent.7.2.10 The pulling cable shall be pulled by a winch that israted at a no-load cable speed of minimum 7.5 ft/min, and 4ft/min at full load.7.2.11 The force required to bend each carrier pipe andjacket size combination shall
