PTFE Lined 90 Degree Elbows

PTFE Lined 90 Degree Elbows will become the ultimate solution for corrosion resistance of chemical pipelines. In the scenario of strong acid, strong alkali, or high temperature medium transportation, the reliability of the pipeline system directly determines the production efficiency and safety. PTFE Lined 90 Degree Elbows has become the preferred pipe fittings in the chemical, pharmaceutical, semiconductor and other industries with its unparalleled corrosion resistance and long life.

1. Extreme corrosion resistance

 PTFE lining can withstand 98% concentrated sulfuric acid, 50% hydrofluoric acid, strong alkali, and organic solvents, with a less than 0.01mm/year corrosion rate.
 Compared with ordinary stainless steel elbows, the life of PTFE Lined Elbows 90 is extended by more than 5 times, greatly reducing the cost of equipment replacement.

2. High temperature and high pressure adaptability

 Supporting working conditions from -50℃ to 200℃, the lining layer and the carbon steel shell are tightly combined through a hot pressing process without the risk of falling off.

 90 Degree Dn500 Pipe Elbow is designed for large flow, with a diameter of 500mm and a pressure of up to 16Bar, meeting the needs of large-scale production.

3. Zero pollution and low friction

 PTFE has a smooth surface (roughness Ra≤0.8μm), prevents media residue, meets FDA standards, and is suitable for medical and food-grade fluids.

 The friction coefficient is only 0.04, which reduces fluid resistance and saves 15% of pumping energy.

Application scenarios and industry cases

• Chemical industry: A chlor-alkali enterprise uses PTFE Lined 90 Degree Elbows to replace traditional fiberglass elbows, extending the maintenance period of hydrochloric acid pipelines from 6 months to 5 years.
• Semiconductor industry: In ultrapure water systems, PTFE Lined Elbows ensure that there is no metal ion precipitation and the purity level is maintained at 18.2MΩ·cm.
• Environmental protection engineering: DN500 elbows are used in exhaust gas scrubbers, which can withstand corrosion from sulfur-containing wet flue gas and reduce annual operating costs by 40%.
