PTFE Compression Molded Pipes

Overview

Anhui Xinfulong's PTFE (Polytetrafluoroethylene) compression molded pipes are engineered for the most demanding fluid handling applications in semiconductor, wet chemical, pharmaceutical, and chemical processing industries. Manufactured through precision compression molding technology using high-purity PTFE granular resin-, our molded pipes deliver exceptional corrosion resistance, ultra-wide temperature tolerance, and superior purity — making them the ideal choice for transporting aggressive chemicals, high-purity media, and corrosive fluids.

With a diameter range from 20mm up to 1800mm- and operating temperature from -180°C to +260°C-, PTFE compression molded pipes offer unmatched versatility across a broad spectrum of industrial applications.

Key Features

• Exceptional Chemical Resistance — PTFE is inert to virtually all chemicals, including concentrated acids (sulfuric, hydrochloric, nitric, hydrofluoric), alkalis, organic solvents, strong oxidizers, and aggressive media-. Ideal for handling the most corrosive process fluids.

• Ultra-Wide Temperature Range — Maintains stable performance from -180°C to +260°C-, with excellent mechanical properties retained across the entire range. Suitable for both cryogenic and high-temperature processes.

• Superior Non-Stick Properties — PTFE's extremely low surface energy and coefficient of friction prevent adhesion, scaling, and build-up, ensuring smooth flow and easy cleaning-.

• Excellent Electrical Insulation — PTFE is the best electrical insulator of all known plastics-, making it ideal for wire and cable jacketing and electrical applications.

• Ultra-Low Water Absorption — Water absorption rate below 0.01%- ensures dimensional stability and prevents contamination of process media.

• High Purity — No metal ion release or contamination of transported media, meeting the stringent cleanliness requirements of semiconductor and pharmaceutical applications.

• Dimensional Stability — Low molding shrinkage (typically 4-6%)- with precision-controlled manufacturing ensures consistent dimensions and reliable fit.

• Non-Toxic and Non-Flammable — PTFE is physiologically inert, non-toxic, and non-flammable, safe for food, pharmaceutical, and sensitive applications.

Technical Specifications

Manufacturing Process

Our PTFE compression molded pipes are produced through a carefully controlled four-step process-:

1. Mixing — High-purity PTFE granular resin is precisely blended to ensure uniform consistency.

2. Preforming — The PTFE powder is evenly loaded into precision molds and compressed at room temperature into dense preforms (blanks).

3. Sintering — The preforms are sintered at controlled high temperatures, allowing the PTFE particles to fuse into a homogeneous, void-free structure.

4. Cooling — The sintered pipes are gradually cooled under controlled conditions to ensure dimensional stability and optimal mechanical properties.

For lined piping applications, we also employ advanced lining processes including isostatic molding, injection molding, transfer molding, and ram/paste extrusion to ensure superior bonding between the steel shell and PTFE lining.

Applications

Our PTFE compression molded pipes are widely deployed in:

• Semiconductor Manufacturing — Ultra-pure chemical transport, wet etching, wafer cleaning, and high-purity fluid handling systems

• Wet Electronic Chemicals — Transportation of high-purity acids, solvents, and corrosive chemicals
