Hdpe duct jointing : • all of joint fittings must be compliant to astm f 2176. • the hdpe duct can be joint using the mechanical or any equivalent technique such as fusion method. • the mechanical joint fitting is installed by pushing the back nut, spring follower and rubber ring on to the plain pipe end, and then inserting into the socket of the filling. The back nut is then tightened by hand. • no special machine required to install the fitting as shown in appendix 3. Hdpe duct sealing plug : Used for sealing the duct ends before cable installation, prevents ingress of dirt, water, moisture, insects etc. As shown in appendix 3. Hdpe duct 90ᶱc bend : Long sweep 90° bend is used for routing of conduits around corners and for the interfacing between the duct and the base of a cabinet or termination boxes as shown in
