室内采暖支管所用管材 PP-R塑铝稳态管与PPR管比较
does not leak oxygen, hygienic comparison: PP-R steady-state aluminum plastic pipe with metal structure, no oxygen permeability， to protect the heating system, high health.
Compressive strength: PPR steady-state Aluminum plastic pipe high compressive strength, should not be deformed, but hot water heating system in PPR pipe easily deformation
Connection: Two pipes are used hot melt connection, with the same material PP-R pipe fittings for hot melt connection, no leakage
Two kinds of pipe in the price comparison: PPR steady-state Aluminum plastic pipe dn32: 15 yuan / m, PPR dn32: 10 yuan / m
