Engineered Durability and Precision

Constructed using high-grade SS304 or SS316 stainless steel and lined internally with virgin PTFE, this sight flow indicator offers exceptional chemical and corrosion resistance. With a dimensional tolerance of 0.2 mm and robust mechanical strength, it meets stringent international standards, making it ideal for integration into critical industrial flows where precise observation is crucial.

Versatile Industry Applications

The design, finish, and chemical compatibility of the PTFE lined sight flow indicator make it highly suitable for aggressive chemical processes, pharmaceuticals, petrochemical plants, and food processing industries. It enables safe, contamination-free visual inspection of flow, contributing to both operational safety and process optimization.

Reliable Sealing and Easy Installation

Featuring flanged ends drilled according to ANSI B16.5, DIN, or BS standards and equipped with fluoropolymer/PTFE gaskets, installation is straightforward while ensuring secure, leak-free connections. The polished external surface and durable internal lining further guarantee a long service life and minimal maintenance.

FAQs of SS PTFE Lined Sight Flow Indicator:

Q: How does the PTFE lining contribute to the performance of the sight flow indicator?

A: The PTFE lining offers excellent resistance to corrosion and chemical reactions, ensuring durability and safe handling of aggressive or sensitive media. It also provides a smooth, non-stick surface to prevent contamination and maintain flow visibility.

Q: What is the typical installation process for this sight flow indicator?

A: Installation involves flanged connections that are drilled as per ANSI B16.5, DIN, or BS standards. The indicator is mounted in-line with compatible flanges on the pipeline, using PTFE or fluoropolymer gaskets to form a secure, leak-proof seal.

Q: When should I select this sight flow indicator for my application?

A: This sight flow indicator is ideal when you require visual confirmation of flow in pipelines handling corrosive, hazardous, or high-purity fluids, commonly found in chemical, pharmaceutical, petrochemical, and food processing sectors.

Q: Where can this flow indicator be effectively used?

A: Its robust construction and chemical resistance make it suitable for installation in industrial facilities such as chemical plants, pharmaceutical laboratories, petrochemical units, and food processing industries, particularly in pipelines transporting reactive or pure substances.

Q: What are the benefits of using a stainless steel body with virgin PTFE lining?

A: Combining stainless steel with virgin PTFE lining provides both mechanical strength and chemical inertness. This synergy ensures high resistance to pressure and temperature, while the lining safeguards against corrosion, extending the products operational life.

Q: How do I choose the correct size and specification for my needs?

A: Selection depends on your pipeline diameter (ranging from 15 mm to 300 mm or 1/2 to 12), pressure rating (up to 10 bar), flange type, and compatibility with existing industry standards. Ensuring the right material grade (SS304 or SS316) and lining guarantees optimal performance.
