Pressure Retention: Maintains system pressure integrity under fire emergency conditions.
-
Leak-Proof Sealing: Grooved coupling design with gasket ensures secure, sealed connections that prevent water leakage.
-
System Flexibility: Allows for easy system expansion, modification, or maintenance without major pipeline reconstruction.
6. Installation Instructions
-
Inspection: Check all fittings for damage or defects before installation. Ensure gaskets are clean and undamaged.
-
Pipe Preparation: Cut pipe ends square and deburr to remove sharp edges. Clean pipe surfaces thoroughly.
-
Gasket Placement: Apply lubricant to gasket (if required) and position it evenly over the pipe end.
-
Fitting Assembly: Slide the grooved reducing tee over the pipe ends, ensuring proper alignment.
-
Coupling Installation: Place the housing over the gasket, insert bolts, and tighten nuts evenly in alternating sequence to the recommended torque specifications.
-
Pressure Test: After full installation, conduct a hydrostatic pressure test to verify all connections are leak-free.
-
Inspection: A qualified inspector should review the installation before the system is placed into service.
7. Precautions
-
Always wear appropriate personal protective equipment (PPE) during installation.
-
Do not exceed the maximum working pressure rating of 2.5MPa (363 PSI).
-
Ensure all grooved ends are free from scratches, dents, or deformation before installation.
-
Use only recommended gaskets and lubricants compatible with the application medium.
-
Store fittings in a dry, covered area to prevent rust or coating damage before use.
-
If any fitting shows visible damage, DO NOT install – replace immediately.
