The basic requirements for plastic pipes used in floor radiant heating systems are: good flexibility (convenient construction); meet the temperature and pressure conditions of floor heating; and can meet the synchronization of the service life of the building. The plastic pipes used in the ground radiant heating system should have good heat resistance, pressure bearing capacity, stress crack resistance, creep resistance, aging resistance and connection reliability from the perspective of safety and life. The plastic pipes used in the ground radiant heating system should have safety, longevity and good flexibility from economic considerations, and the cost-effectiveness is the best.
