Compared with the traditional cast iron pipe and galvanized steel pipe, the PPR pipe has the advantages of light specific gravity, low heat conductivity coefficient, good heat resistance, simple and convenient installation and maintenance, long service life and the like, and is widely applied to cold and hot water systems of buildings and the like. However, the PPR pipe has poor strength, thick wall thickness and high production cost. The hygiene performance may be problematic due to the presence of regrind and the aging of the plastic, and the execution of the plastic-limiting order also affects the production of PPR tubing to some extent. Although the heat conductivity coefficient of PP-R is 0.21w/mk, which is lower, the PP-R is still large in heat loss when used for a hot water channel and under the condition of large temperature difference, and most of PP-R pipes in the market have no heat preservation effect or are not ideal in heat preservation effect. And the low-temperature impact resistance of the PP-R pipe is poor, so that a lot of inconvenience is caused to the installation and the use of the PP-R pipe in cold regions in winter.
Aiming at the defects of the prior art, a research and development person needs to develop a heat-preservation PPR steel-plastic composite pipe which has reasonable design, can play a role in heat preservation and low-temperature impact resistance, can prevent heat loss and low-temperature embrittlement, and has high strength and good sanitary performance.
