BS EN 15632 is a European Standard on district heating pipes. The main aim of the BS EN 15632 series is to provide manufacturers with best industry practices to demonstrate the performance of pre-insulated flexible pipes such that they are fit for its intended use.
BS EN 15632-1 is the first part of the series that provides classification, general requirements and test methods for flexible, pre-insulated, directly buried district heating pipe systems.
Depending on the pipe assembly, BS EN 15632-1 is valid for maximum operating temperatures of 95 °C to 140 °C and operating pressures of 6 bar to 25 bar.
The pipe systems are designed for a lifetime of 30 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in EN 15632-2 and EN 15632-3.
BS EN 15632-1 on district heating pipes is useful for:
Flexible pipe systems in district heating networks are of common technical usage. In this regard, the main objective of BS EN 15632-1 is to assure quality including product-related lifetime, safety in use, economical energy usage and to facilitate comparability in the market.
BS EN 15632-1 provides the best industry recommendations on product characteristics and includes procedures for testing and marking of pre-insulated flexible pipes. The test methods help determine flexibility and compressive creep at elevated temperatures of the insulation material. Moreover, test procedures to determine thermal conductivity and the calculation of the heat flow from the medium to the ambient loss of pre-insulated buried district heating pipes, is also covered in BS EN 15632-1. It also provides methods for determination of design values for the radial thermal resistance.
Thus, if you are a manufacturer of district heating pipes complying with BS EN 15632-1 can help demonstrate the performance and credibility of pre-insulated plastic pipes, making these piping systems highly efficient and sustainable.
