  • 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 ...

PPN Pipes Industry knowledge

What are the main materials of PPN pipes?

1. Modified Polypropylene (PP): PPN pipes use polypropylene (PP) as the matrix, which is β-modified or copolymerized to give it higher temperature resistance, chemical corrosion resistance, and aging resistance.

2. High Transparency and Low Water Absorption: PPN material has an extremely low water absorption rate (≈0.01%), and hardly expands in aquatic environments, making it suitable for industries highly sensitive to moisture, such as cleanrooms, pharmaceuticals, and semiconductors.

3. Excellent Mechanical Strength: The modified PPN pipe wall is dense, significantly improving impact strength and pressure resistance, and can operate stably in a wide temperature range of -10℃ to +100℃.

What are the differences between PPN pipes and ordinary PP pipes (PPH)?

1. Compositional Differences: PPN pipes use polypropylene raw materials directly, while PPH pipes are β-modified from ordinary PP to form a more uniform and delicate β-crystalline structure.

2. Performance Comparison:

Chemical Resistance: PPN performs better in strong acid and alkali environments, exhibiting stronger corrosion resistance; while PPH also possesses good chemical resistance, it is slightly inferior.

High Temperature Resistance: PPN can be used continuously at temperatures above 100℃, suitable for high-temperature process pipelines; the maximum operating temperature of PPH is generally around 90℃.

Abrasion and Aging Resistance: PPN pipes exhibit superior abrasion resistance and anti-aging properties, resulting in a longer service life, making them particularly suitable for harsh conditions such as chemical and pharmaceutical industries.

3. Application Scenarios: PPN is more inclined towards high-end photovoltaic, semiconductor, chemical, and pharmaceutical fields where extremely high material purity and temperature resistance are required; PPH is commonly used in general industrial pipelines, water supply and drainage, and medium- and low-pressure transmission systems.
