Grp installation procedure 1. Graphite India limited (G.R.P. Division) Method of Installation of GRP Pipe METHOD STATEMENT FOR UNDERGROUND INSTALLATION OF GRP/FRP PIPES IN THE TRENCH GRP SEA WATER PIPING SYSTEM - 700MW CCPP PIPAVAV PROJECT. The bed must be over-excavated (manual digging is enough) at each coupling joint location to ensure Always remember the following key rules when installing a Cure It GRP roof. These are areas where mistakes are most commonly made: Decking • When using OSB3 18mm T & G boards always lay the boards with the tongue and groove gap face up (usually writing face up). • Always stagger the joints. • Do not use sections of boards less than 400mm. 3.1 - Basics of installation Superlit GRP pipes are designed to provide a continuous excellent performance for long years if the installation is performed correctly as per the instructions. The installation of HOBAS GRP Pipes is subject to applicable stan-dards and guidelines such as EN 1610 and ISO/TS 10465-1. Correct installation always requires individual calculations and comprehensive planning by certified engineers. In addition to all applicable standards and guidelines, engineers shall at 91-265-2250333 Email: [email protected], [email protected] FIBER REINFORCE PVT. LTD.

This should be installed with a min 75mm to max 150mm below the GRP front edge flange. A batten and flashing support seat are now fixed in place under the bottom flange of the dormer. Installation Procedure for GRP Sectional Water Tanks Ensure that concrete beams should be horizontal & smooth finishes from top. Painting if required in civil detail. Steel skid base shall be fixed on the concrete beams. Steel skid base shall be leveled properly as required to drain off the Tanks water. • Never use a petroleum based lubricant for GRP pipe the coupling with pipe. • Fix a cross bar on the coupling face. Use two nylon jointing. slings & fix the come-along jacks (pullers) at each side • Ensure that the coupling & pipe is aligned. of the pipe spring line. • Start tightening the puller from both ends same time. Wrap 5 layers of 270 gr/m² 5 cm width for dia 25 through 350 mm and for dia 400 through 2000mm 5 layers 270 gr/m² 10 cm width have woven roving around the "weld" taking care that every following layer applied over a totally impregnated previous one. For this impregnation use a brush or roller. The woven rovings are wrapped around under tension. A GRP Roofing system is a lightweight, single-ply membrane which is applied to secured OSB 3 decking boards. Its core materials consist of Resin, Fibreglass Matting and Topcoat. Once applied correctly, a GRP Roof will last in excess of 20 years. Once cured fibreglass is inert and it will not rot or corrode. consideration during installation. • Begin installation in a corner. Mark a plumb line 48 1/8" from the corner. • Install the corner molding and apply silicone sealant in the channel of the molding. • Apply the adhesive to the backside of the FRP panels using a crosshatch patte
