1. Overview and Market Demand of Reinforced PPR Sanitary Hot Water Pipes
Reinforced PPR sanitary hot water pipe is a new type of high-performance environmental protection water supply pipe optimized on the basis of traditional random copolymer polypropylene raw materials. Through multi-layer composite reinforcement technology or material modification reinforcement technology, the pipe overcomes the shortcomings of ordinary PPR pipes such as low high-temperature creep resistance, poor pressure bearing stability, and easy thermal deformation. It fully complies with international sanitary water supply pipe standards and is specially used for long-term conveying of domestic hot water and clean drinking water.
1.1 Core Performance Characteristics of Reinforced PPR Hot Water Pipes
Different from ordinary single-layer PPR pipes, reinforced PPR sanitary hot water pipes have excellent comprehensive performance. The reinforced structure significantly improves the pipe’s tensile strength, ring stiffness, and high-pressure bearing capacity. The long-term working temperature can stably reach 95℃, and the maximum instantaneous temperature resistance can reach 110℃, which fully adapts to the continuous hot water supply demand of domestic and commercial systems. In terms of sanitary performance, the raw materials and molding process do not add any harmful additives, with no precipitation, no scaling, and no secondary pollution to water quality, meeting the strict sanitary standards of drinking water pipelines.
In addition, the reinforced PPR pipe has ultra-low thermal expansion coefficient, effectively avoiding pipe bending, deformation, and interface cracking caused by thermal expansion and cold contraction in long-term high-temperature operation. Compared with ordinary PPR pipes, the service life is increased by more than 30%, and it can maintain stable structural performance for more than 50 years in conventional buried and wall-pipelaying environments, greatly reducing pipeline maintenance and replacement costs in later engineering stages.
1.2 Market Application Demand and Industry Development Trend
With the continuous upgrading of global building water supply standards and the improvement of public awareness of drinking water health, ordinary low-performance PPR pipes can no longer meet the construction requirements of high-end residential buildings, star hotels, medical and health buildings, and smart communities. Reinforced PPR sanitary hot water pipes, with their high safety, high temperature resistance, pressure resistance, and long durability, have become the designated pipeline products for high-standard water supply engineering projects.
At present, the market demand for reinforced PPR sanitary pipes maintains a continuous growth trend, and the market has higher and higher requirements for pipe precision, sanitary level, and structural stability. This puts forward higher technical standards for supporting extrusion production equipment, eliminating traditional ordinary extrusion lines with single function and low molding precision, and promoting the iterative upgrading of professional reinforced PPR pipe extrusion equipment.
2. Technical Defects of Ordinary PPR Pipe Extrusion Machine in Reinforced Pipe Production
Most ordinary plastic pipe extrusion machines on the market are designed for single-layer ordinary PPR pipe production, and there are obvious technical bottlenecks in the production of reinforced composite PPR sanitary hot water pipes, which cannot meet the high-standard molding and sanitary production requirements. The core defects are mainly reflected in reinforcement layer molding failure, poor interlayer bonding, unstable dimensional accuracy, and unqualified sanitary performance control.
2.1 Ununiform Reinforcement Layer Distribution and Unstable Structural Strength
Ordinary extrusion machines adopt single-channel die runners and fixed extrusion parameters, which cannot realize uniform distribution and directional composite molding of reinforced materials. In the production process, the reinforced layer is prone to partial thickness deviation, dislocation, and sparse distribution, resulting in inconsistent pressure resistance and temperature resistance of different pipe sections. The finished pipes have hidden dangers of local pressure failure in actual use, which cannot meet the standard requirements of reinforced hot water pipes.
2.2 Weak Interlayer Bonding and Easy Delamination
The temperature control system and melt shunting technology of traditional extrusion lines are backward. The temperature matching of the base material layer and the reinforced material layer is inconsistent during extrusion molding, resulting in insufficient fusion between layers. After long-term hot and cold alternating use, the pipe is prone to interlayer delamination, bulging, and water seepage, seriously affecting the service life and safety of sanitary hot water pipelines.
2.3 Low Molding Precision and Poor Pipe Roundness
Ordinary extrusion equipment has low traction stability and cooling precision. In the production of thick-wall reinforced PPR pipes, it is easy to produce pipe ovality, wall thickness deviation, and surface wrinkles. The dimensional accuracy cannot meet the installation standards of supporting pipe fittings, resulting in poor construction compatibility and high engineering defective rate.
2.4 Uncontrolled Sanitary Production Environment
Traditional extrusion lines lack targeted sanitary protection design. The heating and molding process is prone to local material carbonization and impurity mixing, resulting in trace harmful substances remaining on the pipe surface. The finished products fail to pass drinking water sanitary testing and cannot be used in high-standard clean water supply projects.
