What are Lined Pipes?
Between the material of the pipe and the lined pipe, there is mechanical bonding. We may benefit from the strength of carbon steel as well as the lined material’s ability to resist corrosion by putting it into a carbon steel pipe.
What are PTFE Lined Pipes?
Applications that operate in harsh environments and entail transferring or storing highly corrosive fluids can benefit from the long-term cost-effectiveness of PTFE-lined pipelines and tanks. Due to its chemical inertness, PTFE lining is resistant to many corrosive fluids operating at high pressures or temperatures of up to 230°C.
PTFE Lining Process
According to customer requirements, Fluoro Pacific offers PTFE-lined pipes. A heated PTFE cylinder is stretched (extruded) and put into a pipe as part of the manufacturing process. The PTFE tube most frequently has a larger diameter than the pipe and, because it is a thermoset material, will shrink back to its original size or as much as the metal pipe will allow when tension is released, creating a tight, immovable fit. By heating and compressing the PTFE against the pipe flange face, the extra length of the PTFE rod that is permitted at either end is flared. To expand pipe length or to other metal surfaces, metallic bolts are then compressed to form a tight seal between two flared sides. For extremely corrosive and dangerous applications, SS 304 PTFE Lined Pipes are the best choice.
Benefits of PTFE Lined Pipes
The advantages of employing PTFE include extending the lifespan of pipelines while reducing the likelihood of catastrophic collapse. Any malfunction might lead to damage to the pipe and its surroundings, which would increase the expense of replacing the pipe, cause processing to halt, and—most importantly—pose a risk to people’s health and safety by exposing them to corrosive substances like acids.
Advantages of PTFE Lined Pipe
• Save for fluorine, its derivatives, and extremely violent reducing agents, chemical inertness.
• Low friction coefficient.
• Little absorption of water.
• Non-Toxic.
• Non-Inflammable.
• Excellent resistance against weather.
• An affordable substitute for rare and expensive metals.
• Low operational expenses are ensured through long service lives, lack of maintenance requirements, and ease of installation.
• Exceptional corrosion resistance throughout a broad temperature and pH range.
• For use in applications involving Multi-Component Mixtures.
• Due to designs that follow current International Standards to maintain a hazard-free environment, there is a low probability of failure.
• No media contaminant in the flow.
Where is PTFE Used?
Because of its advantageous characteristics, PTFE is utilized in a variety of products, including PTFE “O” rings, gaskets, valves, wire insulation, insulated transformers, bearings, surface coatings, chemical processing equipment, chemical transport, and PTFE rubber diaphragms, to mention a few.
