Fitting up1 Check the alignment and fixing the pipe ends as close as possible, then prepare the putty.2 Apply the putty with a putty knife filling all the gap。 Wrap Joint Procedure Page 8 to 11 LAMINATION ON THE PIPE JOINT of and attachment B: Installation and Handling Instructions For Rigid Joint Pipe Page 5 to 6.1 Enough catalysted resin should be prepared for about 20 –30 minutes gel time and thorough mixing it.2 Spread a thin layer of catalysted resin directly on the surfaces of the pipe joint laminating area.3 Place of chopped strand mat on the surface of wet out area smoothly and wet it out with the paint wooly roller.4 Continue building by alternating chopped strand mat and woven roving and plete wetting out each one before applying the next ply. No more than 5 plies in one layer. Covered with chopped strand mat.The paint roller roll out over the plies to release big air cavities and any excessive resin. Avoid air getting into the laminate by using steel grooved roller slightly pressed to remove out the air bubbles. The angle of groove roller shall be changed time to time in order to remove the air bubbles in all directions. Keeping in consideration that very limited time has left for the resin to start getting gel, make sure all air bubbles have been taken out prior to start the plies to bee hard. Stop rolling as soon as the resin begin to gel. 5 Continue this procedure until all the sections of the first layer been applied. Make sure that each section overlap with the others at least 5 cm. Let this layer layup cure and cool until it is fortable to touch with the bare hand.Continue using the same procedures with the remaining layers as attachment C: Field lamination( process sheet). Make sure that the last plies of the total layup are chopped strand mat.CAUTION :1 Any kind of movement of pipe section could reduce the bond strength of the initial layup plies have not cured. While the jointing is under progress, the pipes must be restrained before moving.2 Remove the layup if not properly bonded to the pipe, and wash the area with solvent and not to run solvent into uncured. Before applying the layup on this area, insure all solvent has pletely evaporated. Never allow spilled chemical on the pipe surface. This may cause damage to the pipe.3 Each joint lamination team should be formed by at least two workers, trained and skilled.Other details see attachment A: Field Butt amp。 Wrap Joint Procedure Page 12 to 14.13.
