What are the Variations of PVF?

PVF encompasses a broad range of products with varying functions and materials. The choice of materials depends heavily on the application to ensure safe and efficient operation. Factors such as the substance being transported, pressure, flow rate, and temperature guidelines influence the selection. Typically, the piping material dictates the material for associated fittings and valves.


Pipes are the backbone of the PVF industry and set the standard for selecting other components. They come in a variety of shapes, sizes, and materials, with the specific type chosen based on environmental and functional requirements. The most commonly used pipes in the PVF industry include:

Steel Pipes

Known for their durability, steel pipes are often employed in underground applications like water, gas, and sewage systems. They are available in different forms:
  • Galvanized Steel: Zinc-coated to resist rust and corrosion, galvanized steel pipes are commonly used in construction, particularly for water supply lines, and can last up to 100 years in most conditions.
  • Stainless Steel: Resistant to corrosion and ideal for sanitation-critical industries like healthcare and foodservice.

Other Metals

Besides steel, other metals are frequently used:
  • Cast Iron: Heavy and primarily used in water distribution and sewer systems, often installed underground.
  • Copper: Ideal for water supply and refrigeration due to its resistance to corrosion and extreme temperatures. It comes in two formats: Copper pipes are also categorized by wall thickness:
    - Rigid Copper: Best for water lines due to its rigidity.
    - Soft Copper: More flexible and used in refrigeration lines.
    - Type K: Thickest, used for water distribution and oil.
