1. Rapid Assembly: Socket Fusion Fittings utilize a hot-melt socket welding process. Welding is completed simply by inserting the pipe into the sleeve and heating for tens of seconds. The overall operation time is significantly shorter than the minutes or even hours required for traditional arc or gas welding. 2. Low O...
View More1. High Temperature Resistance Taking fluoroplastics (PTFE, FEP, PVDF, ETFE, PFA) as an example, their maximum operating temperature can reach 260℃, with a low temperature limit above -18℃. Conventional plastic piping (such as PPR and PVC) can be used stably for a long time below 90℃, but softening or even failure will...
View More1. Determine the Media Characteristics First, determine whether the medium being transported by the plastic pipe is water, oil, chemical solvents, or gas. Select materials based on its corrosiveness, viscosity, and temperature range. PPR is suitable for hot water, PVC for acid and alkali media, and PE-RT for low-temper...
View MoreWhat are 1.0MPa β-PPH pipes?
1. Material Nature: β-PPH (β-crystalline polypropylene homopolymer) is a homopolymer polypropylene obtained through β-modification. It possesses a fine and uniform β-crystalline structure, exhibiting excellent chemical corrosion resistance, wear resistance, and insulation properties.
2. Pressure Rating: The product is designed for a working pressure of 1.0MPa, meeting the medium-to-low pressure transmission needs of industries such as solar energy, semiconductors, chemicals, and pharmaceuticals.
3. Sizes and Specifications: The company offers various pipe diameters and wall thicknesses, which can be customized according to customer piping systems, compatible with various valves, fittings, and accessories.
4. Application Areas: Widely used in high-requirement industrial piping systems such as photovoltaic brackets, semiconductor cooling, chemical media transportation, environmental water treatment, and pharmaceutical manufacturing.
How are the maximum operating temperature and low-temperature brittleness of 1.0MPa β-PPH pipes assessed?
1. Maximum Operating Temperature: The upper limit of the operating temperature of β-PPH pipes is generally 110℃, and can reach 120℃ under special operating conditions, meeting the transportation needs of most industrial heat media. 2. Low-Temperature Performance: The low-temperature embrittlement temperature of polypropylene is approximately -70℃. β-PPH maintains good toughness within the range of -20℃ to -70℃, requiring no additional antifreeze measures for winter construction.
3. Evaluation Methods:
Thermomechanical Property Testing: The upper temperature limit and embrittlement point of the material are determined through experimental data on the coefficient of thermal expansion, yield strength, and impact toughness at different temperatures.
Long-Term Temperature Resistance Testing: The pipe is continuously operated at 110℃ for over 5000 hours, observing creep, hardening, and dimensional changes to verify the reliability of the maximum operating temperature.
Low-Temperature Impact Testing: Impact tests are conducted at -70℃ to ensure the pipe retains sufficient impact absorption capacity even at extreme low temperatures.
