PVDF Pipe Sizes and Dimensions

Q: Which is better, PVDF or metal pipes?

The biggest difference is that PVDF pipes are more inert and do not require passivation. Thus, it will never rust, but metal piping is heavily susceptible to environmental corrosion. Unlike metal and SS pipes, PVDF pipes are inert to hydrogen gas, making them suitable for transferring chlorine-based chemicals and compounds such as Hydrochloric acid (HCL). Apart from that, installation costs for both pipes are similar.

Hello people; I will share an extensive guide on PVDF Pipe Sizes and PVDF Pipe dimensions today. So without further ado, let’s get started.

PVDF plastic is a type of thermoplastic fluoropolymer with a wide range of applications due to its impressive properties. These include exceptional chemical resistance, good processability, high mechanical strength, Piezoelectric and pyroelectric properties, and a high heat deflection temperature under load. These attributes make PVDF stand out among other thermoplastics.

Salient Features of PVDF Pipes

No roughing like metal pipes. Since there is no roughing, passivation is also not needed. (Passivation is constantly needed in SS and metal pipes)
Easy to maintain with meager costs. The PVDF pipe boasts a melting point of 178°C to resist steam sterilization. But also can withstand sterilization by ozone without post‐sterilization cleaning.
PVDF is one of the hardest fluoropolymers and boasts the highest tensile strength in all plastics. Its abrasion resistance is often compared with stainless steel.
PVDF has excellent resistance to deionized water, outstanding thermal stability, and high resistance to sunlight degradation. Its low slip coefficient makes it difficult for microorganisms like fungi and bacteria to grow on it. On the contrary, a limitation exists on how much a metal pipe can be smoothed out. On this front, metal pipes certainly don’t stand a chance against plastic pipes, let alone pipes made from PVDF.
PVDF contains no additives. Meaning nothing will leach out. It is manufactured with 100% pure resin.
Long service life, even under severe corrosive conditions.

PVDF Pipe Applications

As PVDF plastic is known for excellent mechanical and Piezoelectric properties. Thus it is utilized in multipurpose specialty plumbing well suited for several industries. It is often considered the best option for chemical processing and transfers within pharmaceuticals, electrical systems, food & beverage petrochemicals, and energy applications.

Chemicals handled and transferred in PVDF piping include bromide solutions, sulphuric acid, hydrochloric acid, nitric acid, alcohols, chlorinated compounds, aromatic solvents, and aliphatic solvents.

The most commonly used products for PVDF piping include food syrups, wine, beer, ultrapure water, various liquid beverages, and pharmaceutical chemicals & compounds. However, PVDF piping is not limited; it has been rapidly accepted for transferring engine fuels, diesel, gasoline, refined or unrefined oil, and ethanol and biodiesel blends.

Uses By Industries

PVDF pipe sizes and dimensions differ from other pipes due to their applications. Below are some of the major applications sorted by verticals.

Metal Preparation – High-temperature Acids

Petrochemicals – Alkylation acids, hydrocarbon mixtures

Waste Water – Chemical Mixture, Outdoor Exposure

Food & Beverages – Steam cleaning, aggressive food agents, acidic foods

Pulp and Paper – Bleaching Chemicals and acids

Semiconductor – Acids, ozone, high purity water, FM 4190

Mining – Acidic mixtures, abrasive slurries

Biotech/Pharmaceutical – Ozone, cleaning agents, acids

Plenum Pipe – Acid waste drainage

FAQs

Can your thread PVDF pipe?

PVDF pipes and PP, PVC, and CPVC can be threaded using special pipe dyes with special fittings provided with threaded connections. The only thing that needs to be taken care of is that the threaded pipe must be derated by 50% from solvent-cemented systems.

Which one is better, PVDF or PVC?

Both PVDF and PVC are reliable piping options but are not similar. They have many differences in properties. PVDF is more mechanically durable and has excellent chemical, UV, and nuclear radiation resistance. PVDF is joined using the heat fusion welding technique, and PVC is joined using primers and cement.
