RTR and Thermoplastic Piping Handling, Storage and Preservation Checklist
- Pipe shall be stored out of direct sunlight in a building or under a cover that allows free air circulation.
- Pipes shall not be stored directly on the ground. Pipes shall be placed on mounds or sleepers.
- Racks shall conform to factory shipping packages for each pipe size. Shelves shall be provided for continuous support of the pipe.
- If loose pipes are stacked on each other, the stack height shall not exceed 1.5 m. Adequate side support shall be provided to prevent slipping or rolling.
- If pipe is stored on racks or bearing boards, the supports shall be at least 75 mm wide. Supports shall be spaced on 3 m centers maximum with the first supports 1.5 m from the end of the pipe.
- All supporting surfaces shall be free of sharp objects.
- Thermoplastic and RTR fittings shall be stored in their original containers. Fittings shall be stored in a building or under a cover that allows free air circulation.
- Solvent cement and primer for thermoplastic piping shall be stored in an air-conditioned building with a maximum temperature of 26.7°C.
- Gaskets, O-rings, and locking keys shall be stored flat on racks below 38°C and out of direct sunlight.
- Adhesive for RTR piping shall be stored in an enclosure where temperatures do not exceed 38°C.
- Pipe and fittings shall be properly protected from impact, especially on their ends. They shall not be thrown, dropped, bumped, hit, or dragged and pushed over abrasive surfaces.
- Loose thermoplastic or RTR pipe shall be handled by hand or, if the pipe is too heavy, using nylon or cotton strap spreader slings.
- Adhesive and solvent cement containers shall be tightly closed when not in use, and shall be returned to the storage facilities to minimize exposure to excessive temperatures.
- Solvent cement and primer for thermoplastic and RTR piping should not be stored if no expiration date is clearly marked on the container.
- End protectors on pipes, flanges, weld bevels, threads, and socket ends shall be firmly attached.
