PEX-b/PEX-b oxygen barrier (EVOH)
1. It should have good flexibility and comply with the temperature and pressure usage conditions of floor heating. It can simultaneously meet the service life of the building.
Features:
1. It should have good flexibility and comply with the temperature and pressure usage conditions of floor heating. It can simultaneously meet the service life of the building.
2. The heating pipe of the low-temperature hot water system should be selected according to its working temperature, working pressure, service life, construction and environmental performance and other factors, and its pipe series (S value) and material wall thickness should be selected after comprehensive consideration and technical and economic comparison.
3. The quality of the heating tube must comply with the provisions of the current national standards.
4. Various inspection reports such as heating tube stability test, thermal cycle test, cyclic pressure impact test, cross-linking degree test, longitudinal expansion rate and hydraulic test should be provided.
5. The appearance quality and size should be checked, and the inner and outer walls of the pipe should be smooth. Bubbles, cracks, obvious scratches, dents, color differences and decomposition and discoloration are not allowed. The appearance quality and size should comply with GB/T18992.2-2003 standard.
6. The heating pipe of the low-temperature hot water system is a hidden project and must ensure a service life of 50 years.
