Basic Mechanical Methods and Materials
Part 3 EXECUTION
3.1 EXAMINATION
A. Do not begin installation until substrates have been properly prepared.
B. If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2 PREPARATION
A. Clean surfaces thoroughly prior to installation.
B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
3.3 INSTALLATION
A. General: Grooved piping installation shall meet ANSI B-31.1 - ANSI B-31.9 Codes for Pressure Piping.
B. Install in accordance with manufacturer's instructions.
C. Pipe ends shall be clean and free from indentations, burrs, rust or damage.
D. Field grooving or pipe cutting of galvanized pipe may require repair of possible damaged galvanized pipe ends. Two coats of spray-on "liquid-
galvanize" are recommended.
E. Install rigid couplings with tongue-and-groove housing for precise coupling alignment and engagement. Install tines in the housing key section
to provide a rigid-like pipe connection.
F. Companion or mating fanges shall have a fat hard surface and shall be free from gouges, undulations or deformities. Use fange gasket sealing
rings if mating surfaces are not uniform.
G. Plain-end coupling and ftting installation shall comply with specifc torque and installation requirements. Consult current manufacturer's
product installation data.
H. Gasket lubricant shall be used to assure proper coupling gasket seating, and conformance with gasket service usage.
3.4 VALVE INSTALLATION
A. Tri-Service Valves - Models FTV-S, FTV-A:
1. Mount valve to a spool piece on the discharge side of the pump. Spool piece required is based on a minimum recommended space of 12
inches (305 mm) for pump sizes 2 inches by 2 inches (51 mm by 51 mm) to 6 inches by 6 inches (152 mm by 152 mm) and 24 inches (610 mm)
for pump sizes 8 inches by 8 inches (203 mm by 203 mm) to 12 inches by 12 inches (305 x 305 mm).
2. Do not mount valve directly to pump to avoid causing undesirable noise in the system.
3. Leave suffcient clearance around valve for valve removal or repair.
4. Install valve in the direction of fow arrows on valve body.
5. Mount valve to fanged equipment using Gruvlok Flange Adapter or industry standard grooved coupling, suitable for system pressure and
temperatures encountered.
6. Valve body has been designed to handle the weight of the pump on vertical in-line installations. The valve body is not designed to support
the piping weight. Support piping by hangers. Provide pipe supports under valve and strainer bodies.
