PPH Piping System

Features and Benefits of STARKE PPH Pipes & Fittings:

Superior Quality Materials

Using high-quality PPH raw materials ensures that the fittings have excellent tensile strength, durability, and chemical resistance.

Resistant to Stress Cracking

Starke PPH has the ability to resist stress cracking and enhances the reliability of our fittings, even under high-stress conditions.

Easy Welding and Installation

The welding properties of PPH make it easier to join pipe fittings, reducing installation complexity.

Working Temperature Range

PPH fittings are stable up to around 100°C, making them suitable for hot water, chemical systems, and other moderate temperature applications.

Practical Testing for Quality Assurance

Performing tests ensures the final product meets the required standards for real-world applications.

Chemical Resistance

PPH is highly resistant to a wide range of chemicals, making it ideal for industries like chemical processing and water treatment.

Corrosion Resistance

Unlike metal pipes, PPH will not rust or corrode when exposed to moisture or chemicals, leading to longer service life.

Lightweight

PPH pipes are lighter than metal pipes, making them easier to handle and install.

Cost-Effective

PPH provides a cost-effective solution for industries that require a balance between performance and budget.

Low Maintenance

Due to their durability and resistance to many types of degradation, PPH pipes require less maintenance than other types of pipes.

Properties of PPH Piping

PPH (Polypropylene Homopolymer) piping is commonly used in industries such as chemical, food processing, and water treatment. It is known for its high chemical resistance, strength, and durability, as well as its ability to withstand high temperatures. Below are the key properties of PPH piping:

1. Chemical Resistance

  • High resistance to most chemicals, including acids, alkalis, and solvents.
  • Suitable for transporting chemicals such as hydrochloric acid, sulfuric acid, and others, depending on concentration.

2. Temperature Resistance

  • Max Operating Temperature: PPH piping can withstand continuous temperatures of up to 90°C (194°F) and can handle short-term spikes up to 100°C (212°F).
  • Not as temperature-resistant as other materials like PVDF (Polyvinylidene Fluoride), but still suitable for most industrial applications.

3. Mechanical Properties

  • Tensile Strength: Typically in the range of 30-45 MPa, which provides excellent strength under pressure.
  • Impact Strength: PPH pipes are somewhat brittle at lower temperatures, so they are less impact-resistant than some other plastics.
  • Stiffness: High stiffness, which makes PPH pipes structurally strong but can also make them prone to cracking under impact or stress.

4. Durability

  • Long Service Life: PPH pipes have a long lifespan and can remain functional for many years, even under harsh conditions.
  • UV Resistance: PPH piping can degrade when exposed to UV light, so it may require protective coatings or be used in underground or shielded installations.

5. Corrosion Resistance

  • Non-corrosive: Unlike metals, PPH piping does not corrode, making it ideal for environments with aggressive chemicals and moisture.

6. Flexibility & Ease of Installation

  • PPH piping is relatively lightweight, which makes handling and installation easier compared to metal piping systems.
  • Easier to fabricate and weld compared to other plastic materials like PVC.

7. Density

  • Density: Typically around 0.9-0.91 g/cm³, which makes it less dense than water, allowing it to be lighter than most other piping systems

8. Thermal Expansion

  • PPH has a relatively high coefficient of thermal expansion (about 0.15 mm/m°C), so allowances must be made for expansion and contraction in temperature-sensitive applications.

9. Electrical Properties

  • Insulating: PPH pipes are electrically non-conductive, which is useful in systems where electrical conductivity could be a concern.

10. Welding & Joining

  • PPH pipes can be welded using methods like butt welding, electrofusion, or socket welding, which provide strong, leak-resistant joints.
  • Joining requires proper technique to avoid leaks and ensure the integrity of the system.

11. Cost

  • PPH is typically more affordable than other high-performance plastics like PVDF, making it a cost-effective option for many industrial applications.
