Pb SERIES Environmental protection and stability：polybutene (Pb-H), composed of only carbon and hydrogen elements, has stable chemical performance,
known as “gold in plastic’‘.
Smooth wall：the inner wall is smooth and not suitable for scaling; the water flow speed is fast, and it is convenient to clean pipe in non-heating
season.
Easy installation：the pipe has good flexibility, impact resistance and light weight(density0.90~0.94g/cm3), easy to be bent, constructed, transported
and operated with hot-melt welding under 235(±5)℃.
Temperature and pressure resistance：it has stable performance and good long-term hydrostatic performance, and can adapt to harsh heating
environment.
Application:
Low temperature floor radiant heating system
Solar hot water system water distribution pipeline
High temperature radiator heating system
Snow melting pipeline system under the highway
Large parking lot
