PTFE Lined Steel Reducing Tee

 

Yancheng Tongtong Fluorine Plastic Manufacturing Co., Ltd. specializes in producing high-performance PTFE Lined Steel Reducing Tee products that are ideal for use in highly corrosive and high-purity fluid handling systems. These specialized fittings are designed to provide reliable, leak-free connections between pipes of different diameters, while offering excellent chemical resistance and mechanical strength. With over 15 years of expertise in fluoropolymer-lined piping systems, we deliver durable and cost-effective solutions for demanding applications in chemical processing, pharmaceuticals, electronics, water treatment, and more. Our PTFE Lined Steel Reducing Tees are manufactured by lining high-quality carbon steel or stainless steel bodies with a seamless, chemically inert PTFE liner. This ensures that corrosive media never come into contact with the metal body, thus extending service life and minimizing maintenance.

 

Product Features:

Excellent Chemical Resistance: PTFE lining resists virtually all aggressive acids, alkalis, and organic solvents.

Pressure-Rated Construction: Capable of handling up to 1.6 MPa working pressure.

Smooth Internal Surface: Prevents the buildup of solids and ensures low flow resistance.

Anti-Leak Design: Fusion-welded liners with flanged ends for secure, gasket-sealed connections.

Thermal Stability: Operates in a temperature range of -20°C to +180°C.

Q1: What is a PTFE Lined Steel Reducing Tee used for?

A: It connects three pipes of varying diameters in corrosive fluid handling systems, allowing for smooth direction change and diameter reduction without risk of chemical attack.

 

Q2: What temperature and pressure can the fitting handle?

A: Standard designs operate from -20°C to +180°C and can withstand up to 1.6 MPa pressure, depending on liner and steel body specifications.

 

Q3: Can I get a PTFE Lined Steel Reducing Tee in custom sizes?

A: Yes. We offer custom sizes and configurations based on your piping layout, including different branch diameters and flange standards.

 

Q4: How do you ensure the liner is secure and won't collapse?

A: We use fusion-bonded liners with vacuum-locked design, pressure testing, and spark testing to ensure integrity and adhesion to the metal body.
