  • Matching Plastic Valve and Plastic Piping by Pressure Class and Material

    Direct Answer A dependable industrial fluid-handling network is built by matching three variables at once, not by shopping for parts one at a time: the pressure class of the Plastic Piping, the body material of the Plastic Valve, and the connection method that joins them. Pairing a β-PPH or PVDF valve with pipe from t...

  • What Media Flows Through a Ball Valve?

    Direct Answer A ball valve is built to handle almost any flowing media in a piping system — clean water, corrosive acids and alkalis, organic solvents, compressed gases, and slurries with light particulates. The exact media a specific valve can carry depends on the body material and seal compound: PP-H and PPN bodies ...

  • What pressure rating do I need? (0.6 MPa vs 1.0 MPa vs 1.6 MPa)

    For most residential and low-pressure industrial water lines, 0.6 MPa piping is sufficient. For general chemical transfer, cooling loops and standard process water at moderate flow, 1.0 MPa is the common industry default. For compressed media, deep well discharge, high-rise distribution or safety-critical chemical dos...

PVDF Pipes Industry knowledge

What are PVDF Pipes?

1.Material Properties: PVDF (polyvinylidene fluoride) is a high-performance fluoroplastic with excellent corrosion resistance, high-temperature resistance (up to 150°C), and good mechanical strength, enabling long-term stable operation in harsh chemical and semiconductor environments.

2.Applications: Due to its excellent chemical inertness, PVDF pipes are widely used in piping systems in industries such as solar photovoltaic, semiconductors, chemicals, iron smelting, environmental protection, biochemistry, aquaculture, and pharmaceutical manufacturing.

3.Advantages Comparison: Compared to traditional PVC, PE, or metal pipes, PVDF pipes perform better in acid and alkali resistance, salt spray resistance, and UV resistance, and are less prone to aging, resulting in a longer service life.

4.Company Strength: Jiangsu Leiting Precision New Materials Co., Ltd., as a leading PVDF pipe OEM supplier in China, continuously drives material innovation with 81 patents (including 36 invention patents), providing customers with high-quality pipe solutions.

How to select the appropriate PVDF pipe wall thickness and pressure rating based on media type and operating temperature?

1. Determine the Chemical Properties of the Medium

PVDF exhibits excellent resistance to most corrosive media, including acids, alkalis, salts, aromatics, and halogens. When selecting a PVDF pipe, first confirm whether the medium falls within its chemical resistance range.

2. Select the Temperature Rating Based on Operating Temperature

The standard operating temperature range for PVDF pipes is -40℃ to +150℃, within which the material properties remain relatively stable. If the temperature approaches the upper limit, it is recommended to select a higher pressure rating (such as PN1.6) to provide additional safety margin.

3. Match the Nominal Pressure (PN) with the Wall Thickness

Common pressure ratings on the market are PN1.0MPa and PN1.6MPa. The corresponding wall thickness increases with pipe diameter, with typical references as follows (taken from industry standards):

DN20~DN50: Wall thickness approximately 3mm (PN1.0) or 3.5mm (PN1.6)

DN65~DN100: Wall thickness approximately 4mm (PN1.0) or 4.5mm (PN1.6)

DN125~DN150: Wall thickness approximately 6mm (PN1.0) or 6.5mm (PN1.6)
Specific wall thicknesses can be found in the manufacturer's technical manual or the pressure-wall thickness correspondence table in the "PVDF Pipe Specification Standard".

4. Selection based on comprehensive consideration of medium, temperature, and pressure

For example, when conveying concentrated sulfuric acid (highly corrosive) at an operating temperature of 120℃, it is recommended to select a DN65 pipe with PN1.6MPa and a wall thickness ≥4.5mm to ensure sufficient strength and corrosion resistance under high temperature and pressure.
