Introduction

Polytetrafluoroethylene (PTFE) Lined Coils, widely recognized as "The King of Plastics," stand out in the industry for their unparalleled temperature resistance and corrosion resistance capabilities. These innovative products embody the pinnacle of chemical engineering technology, offering a robust solution for handling highly aggressive and corrosive substances. The unique properties of PTFE, including its virtually universal chemical resistance, exceptional thermal stability, and non-stick surface, make it an indispensable material in a broad range of industrial applications, from chemical processing to pharmaceuticals and beyond. The introduction of PTFE Lined Coils has revolutionized the way industries deal with challenging fluids by providing a reliable and durable means of containment and transport.

Product Description

PTFE Lined Coils are expertly engineered to combine the strength of steel with the chemical inertness of PTFE, offering a superior solution for transporting corrosive substances. The construction process involves lining the interior surface of metal pipes with a seamless PTFE liner, creating a barrier that prevents direct contact between the pipe material and the transported medium. This lining technique not only significantly enhances the pipe's resistance to chemical attack but also maintains the integrity of the conveyed substance by eliminating contamination risks.

The process of lining involves careful selection of high-quality PTFE material, which is then molded and sintered to form a liner that perfectly matches the inner geometry of the pipe. This liner is securely fitted inside the pipe, often with the aid of specialized bonding agents or mechanical methods to ensure a permanent, leak-proof seal. The result is a composite structure that leverages the mechanical strength of the outer metal pipe to withstand external pressures and impacts, while the inner PTFE lining provides a smooth, inert surface that resists a wide spectrum of chemicals at temperatures ranging from -100°C to 250°C.

PTFE Lined Coils are particularly advantageous in applications involving harsh chemical environments where traditional materials would rapidly degrade. Their construction ensures that they can handle a variety of challenging substances, including strong acids like nitric acid, sulfuric acid, and hydrofluoric acid, as well as bases, solvents, and other aggressive chemicals without compromise. Moreover, the non-stick properties of PTFE greatly simplify cleaning and maintenance procedures, further enhancing the longevity and reliability of these systems.

Key Features

Chemical Resistance

One of the standout attributes of PTFE Lined Coils is their extraordinary resistance to a wide array of chemical agents. Whether we're talking about strong acids, bases, or even organic solvents, these coils stand their ground, ensuring both longevity and consistent performance. This resistance is inherent to PTFE, which is virtually impervious to chemical attack. This means that industries can rely on these coils for transporting even the most aggressive substances without worrying about degradation or contamination.

Temperature and Pressure Resilience

Another feather in the cap of PTFE Lined Coils is their ability to perform under a broad spectrum of temperature and pressure conditions. Capable of withstanding temperatures ranging from a chilly -100°C up to a scorching 250°C, these coils are designed for versatility. Additionally, they're engineered to handle pressures up to 2.5MPa positively, while also being adept at resisting negative pressure up to 70KPa at room temperature. This makes them exceptionally suited for a variety of operational settings, ensuring reliability and safety.

Non-flammability and Oxidation Resistance

Safety is paramount, and PTFE Lined Coils excel here as well. Their non-flammable nature, with an oxygen index below 90, means they significantly reduce fire hazards in the workplace. Moreover, their resistance to oxidation is a testament to their durability, even in environments laden with strong oxidizing agents. This dual feature of non-flammability and oxidation resistance not only enhances safety but also ensures that the coils maintain their integrity over time.
