2 02/18 oversized configuration to accommodate lateral movement of piping. No area or part of the piping shall be uninsulated due to pipe growth. The space provided for lateral movement shall be at least 1 1/2 times greater than the indicated piping movement. Support guides shall be installed where required to facilitate proper movement of the carrier pipe. The length of the oversized conduit shall not be less than that required to produce carrier pipe flexibility within the stress limits indicated by the ANSI B31.1 Code Pressure Piping. Carrier pipe shall be accurately centered inside the oval conduit at the factory and held in place with stays. Installer shall not remove stays before conduit is placed in its final location, backfill material is placed on both sides of oval conduit, and carrier pipe joints are made in oval conduit sections. WALL PENETRATION SLEEVES: Provide wall penetration sleeves where piping passes through masonry or concrete walls, floors, and roofs. Sleeves in outside walls below and above grade, in floor, or in roof slabs, shall be Schedule 40 or standard weight coated black steel pipe or shall be as specified by the Design Engineer. Space between piping or insulation casing, and the sleeve shall be sufficient to allow proper water tight sealing, but never less than ½". Sleeves shall be held securely in proper position and location during construction. Sleeves shall be of sufficient length to pass through entire thickness of walls or slabs. Sleeves in floor slabs shall extend 2" above the finished floor. In existing concrete manholes or building walls, penetrations may be made using the “core drilling” method providing proper care is taken to drill the holes to the size needed and square to the line of pipe. VENTING IN MANHOLES: Where manholes are required, it is the responsibility of the installer to utilize the N.P.T. outlet on pipe end cap with a gooseneck to the atmosphere above the manhole. FIELD JOINTS: Field joints shall be made with a FRP sleeve, insulation half shells, FRP wrap kits, and a wrap around heat- shrinkable sleeve. The circumferential joint between the FRP sleeve and outer FRP jacket shall be covered with layers of pre-cut fiberglass mat and polyester resin provided by the system supplier. The FRP wrap material shall extend over the adjacent casing to form a homogeneous airtight closure. The joint shall be air tested at 5 psi for a period of 2 hours after the cure is complete utilizing the factory installed air tube running through the entire system. Backfilling shall not be started until the joint has passed the air test. After testing, joint shall be sealed with wrap around heat- shrinkable sleeve. The complete joint shall be installed in accordance with the manufacturer’s requirements. ACCESSORIES: System manufacturer shall provide all required accessories to make the system watertight. This shall include all end terminations, end seals, and gland seals.
