Proper alignment and secure mounting arrangements must be implemented to avoid angular misalignment, vibrations, or any operational interference. The service pipe insulation shall consist of high-quality polyurethane foam with the following specifications: Minimum density of 36 kg/cu m. Minimum 90% closed-cell content. Minimum compressive strength of 40 psi. Thermal conductivity of 0.14 Btu-in/hr/ft²/°F. The insulation shall completely fill the annular space between the service pipe and jacket, ensuring a tight bond with both. The polyurethane foam shall be covered with a durable and weather-resistant jacket to protect against environmental factors and mechanical damage. All necessary fittings, cables, and accessories for the BTU meter installation must be included. The contractor shall conduct comprehensive testing and calibration post-installation to confirm the accuracy and functionality of the meter. All work must comply with the relevant standards, manufacturer guidelines, and tender specifications, ensuring a reliable and durable installation.
