  • Can a check valve be installed vertically?

    Yes, a check valve can be installed vertically, but two critical conditions must be met: the fluid flow must be upward only, and a spring-assisted check valve must be used. Standard swing check valves without spring assistance are designed for horizontal installation only; forcing them into a vertical position will ca...

  • Which Valve Is Easier to Install in Tight Spaces: Butterfly Valve or Ball Valve?

    When space is limited, butterfly valves are easier to install than ball valves. Their wafer or lug-style body clamps directly between two pipe flanges, requiring minimal face-to-face length and no extra support structures. For large-diameter plastic piping systems in particular, the butterfly valve's slim, lightweight...

  • What Types of Plastic Valves Are Best for Corrosion-Resistant Piping Systems?

    Plastic valves are the right choice when your piping system handles corrosive fluids, requires lightweight components, or operates in environments where metal corrosion is a persistent problem. In conditions where pressure stays below 1.0 MPa and temperature below 95°C, plastic valves weigh only 30–40% of equivalent ...

1.0MPa Industry knowledge

What 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.
