Teflon or Kevlar Pipes

About

Solution 1 with Kevlar "Putting New Life into Old Pipes The developed world is crisscrossed with pipeline networks, and many are close to the limit of their working life. Energy suppliers, industry, and public utilities face spiraling costs of replacing mooring lines and pipe networks with corroding steel. Conventional methods of repair or replacement are expensive and disrupt supply and surrounding infrastructure, especially in urban areas. Innovative use of DuPont™ Kevlar® brand fiber, however, helps enable the trenchless renovation of many different kinds of pipeline in a fraction of the time necessary for conventional repair or replacement. Downtime and disruption are minimized. Cost savings can be enormous. Kevlar® fiber helps offer tomorrow’s solution to the limitations of yesterday’s technology: flexible, high-pressure plastic pipes that restore the efficiency of aging pipe networks. In effect, a new pipeline is inserted within the structure of the old. Its tough, flexible construction enables it to be fed around bends and through long lengths up to 2000 meters. Pipeline diameter is virtually unchanged, so there is no loss of volumetric flow. The inner liner is entirely self-contained — the old pipe is only used as a route, so continuing deterioration is irrelevant." https://www.dupont.com/products/strength-members-mooring.html Solution 2 with Teflon coating "How StreaMax™ Coating Systems Work The properties present in StreaMax™ coating systems make them a good choice for oil and gas well tubulars. These properties include: A multilayered system with specific engineered functions assigned to each layer Holiday-free surface throughout the pipe Excellent nonstick and product release properties A wide operating temperature range, from -100 to 260 °C (-150 to 500 °F) Resistance to high pressures up to 3,000 psi and rapid decompression Excellent chemical resistance from H₂S and CO₂ gasses and all acids and bases, even at high temperatures" https://www.teflon.com/en/industries-and-solutions/solutions/productivity-efficiency-flow/streamax-coatings Solution 3 with PTFE tubes "PTFE tubes can be delivered in various diameters and lengths. Up to diameter 120 mm we can supply standard extruded lengths of 1000, 2000 and 3000 mm. Larger diameters up to approx 3000 mm will be moulded. Maximum length depends on the diameter and ranges from 100 mm to 300 mm." https://www.polyfluor.nl/en/products/semi-finished-products/ptfe-tube/
