9 02/18 BEDDING: Bedding material should be sand or other materials free of sharp objects, heavy clods, boulders or frozen lumps as specified by the design engineer. The approved bedding should be used 6" under, around and over the pipe. Utilize good practices that apply to buried pressure piping. ASSEMBLY OF CASING-TITE SLEEVE: Prior to installing the next section of pipe, the Casing-Tite Sleeve should be installed onto this piece. Simply position the sleeve over the casing and slide it all the way on by hand. Proceed with joint assembly as below. ASSEMBLY OF PIPE AND FITTINGS: 1) Lightly sand both the bell and spigot with emery paper. All surfaces must be clean and dry. 2) Pre-warm bonding surfaces after cleaning. 3) Use epoxy adhesive supplied for joining the pipe and fittings. When assembly is ready to be made, add the contents of the small container (hardener) to the large container (resin) and stir thoroughly until a uniform consistency is reached. Never attempt to split a kit. Rubber gloves should be used when handling adhesive and components. 4) With the brush supplied, apply a thin layer of adhesive to the tapered surface on the spigot and bell end of the pipe. 5) Without delay, insert the spigot slowly into the bell using a twisting motion until the pipe locks. Hold for 30 seconds to allow flow of adhesive. Mechanical force such as a shop hammer and block must be used to insure proper locking of the joints in sizes 2"-4". In sizes 6"-12" a come-along must be used to insure a proper locking of the joint. A properly assembled joint will show a small bead of adhesive around the entire circumference of the joint. 6) Place the heating blanket on the joint. For Mil Spec adhesive and ambient air temperatures below 70ºF cure the pipe joint for 1 hour and the fittings for 1½ hours. For ambient air temperatures above 70ºF cure pipe joints and fittings for 30 minutes. Cure all other adhesives for 30 minutes. TESTING: All carrier pipe joints shall be tested in accordance with the contract specifications. Test shall be performed prior to insulating the joints. If no test is specified, it should consist of a hydrostatic test of 150 psi or 1½ times working pressure, which ever is greater, for a period of two hours.
