I. Core Functions and Application Scenarios
Flow Splitting and Connection
As a type of tee, it can split the water flow from the main pipeline into two paths, which is suitable for scenarios requiring multiple water points such as bathrooms and kitchens. For example, when installing a water purifier, water heater, or smart toilet, the male thread tee can be directly connected to the internal thread interface of the equipment without additional adapters.
Compatibility Design
The copper male thread interface is compatible with various standard threads (such as 1/2 inch, 3/4 inch), and can be adapted to mainstream hardware such as valves and water meters on the market. It is especially suitable for flexible docking when transforming old pipeline systems.
Temperature and Pressure Resistance Performance
Made of PPR (random copolymer polypropylene) material, it can withstand a temperature range of -20℃ to 95℃, and the working pressure is usually 1.6MPa (16 kg), meeting the needs of household cold and hot water systems, floor heating and other scenarios.
II. Specification Selection and Technical Parameters
Size Matching
The specification of PPR male thread tee is expressed as "PPR pipe diameter × male thread size". Common combinations include:
20mm PPR pipe with 1/2 inchmale thread
25mm PPR pipe with 3/4 inchmale thread
32mm PPR pipe with 1 inch male thread
50mm PPR pipe with 1.5 inch male thread, etc.
It should be noted that the corresponding relationship between PPR pipe diameter (such as 20mm, 25mm) and male thread size (such as 1/2 inch) to avoid installation failure due to mismatched specifications.
Pressure Rating
The working pressure of mainstream products is 1.6MPa, and some thickened models can reach 2.0MPa (corresponding to S3.2 series), which is suitable for high-rise residential buildings or areas with high water pressure.
Material Requirements
High-quality products use imported PPR raw materials such as Hyosung R200P. Copper parts must meet the H59 brass standard, and the surface is nickel-plated to enhance corrosion resistance and avoid oxidation and water leakage after long-term use.
III. Installation Points and Precautions
Hot-Melt Connection Steps
Cutting and Cleaning: Cut the PPR pipe vertically with a pipe cutter, remove burrs and clean the pipe mouth.
Marking Depth: Mark the welding depth at the pipe end according to the fitting specifications.
Heating Operation: Insert the pipe and fitting into the hot-melt machine die at the same time, heat at 260±10℃ for 5-24 seconds, then quickly dock and keep it fixed for 10 seconds:
Thread Sealing: The male thread interface needs to be wrapped with 20-30 turns of raw material tape, and tightened clockwise until there is no looseness. Avoid over-pressurizing with a wrench to cause the fitting to crack.
Avoidance of Common Problems
Temperature Control: Insufficient temperature of the hot-melt machine will lead to false welding, and excessively high temperature may cause PPR carbonization. It is recommended to use professional tools with temperature control display.
Stress Release: During installation, ensure that the tee and the pipeline are kept in a straight line to avoid stress due to angle deviation, which will affect the service life.
Water Pressure Test: After installation, a pressure test of 1.5 times the working pressure (2.4MPa) is required. A pressure drop of no more than 0.05MPa within 30 minutes of pressure holding is considered qualified.
IV. National Standards and Quality Certification
According to GB/T 18742.3-2002 "Polypropylene Piping Systems for Hot and Cold Water - Part 3: Fittings", qualified products must meet the following requirements:
Materials: PPR raw materials must pass hygiene performance tests, and the lead content of copper parts shall be ≤0.2%.
Performance: No cracking when subjected to 1.0MPa pressure at 95℃ for 1000 hours, and no leakage when subjected to 2.4MPa pressure at 20℃ for 1 hour.
