PTFE Lined Vessel – Corrosion-Proof Reaction and Storage Vessels for Aggressive Media
When you are processing hydrochloric acid, sulfuric acid, chlorine, or other aggressive chemicals in a steel vessel, corrosion is the number one threat to asset life and product purity. Kaxite PTFE Lined Vessel solves this by bonding a seamless fluoropolymer liner to the internal surface of the steel vessel, completely isolating the process media from the metal wall. The result: no vessel wall corrosion, no iron contamination, no premature replacement — just stable, long-term operation even in the most demanding service.
Our PTFE lined vessels are custom-lined to customer specifications and drawings, covering reactors, storage tanks, distillation columns, receivers, and process vessels. Liner materials are available in PTFE, PFA, or FEP, with standard liner thickness of 3 mm and higher thicknesses on request. Every vessel is inspected against multiple quality parameters — liner thickness, bond integrity, spark testing, and dimensional accuracy — before shipment. All products meet ASTM F1545.
Buyers from chemical plants, refineries, pharmaceutical production lines, and water treatment facilities choose Kaxite because we combine factory-direct pricing, fast lead times, and genuine engineering support. Send us your vessel drawing and we will quote within 2 business hours, with material recommendations for your specific media, temperature, and pressure.

VESSEL TYPES WE CAN LINE
Choose the Right Lined Vessel for Your Process
PTFE Lined Reactor
For corrosive chemical reactions, including acid digestion, chlorination, and polymerization. Liner protects the vessel wall from aggressive reagents and prevents product contamination.
PTFE Lined Storage Tank
For storing hydrochloric acid, sulfuric acid, caustic solutions, and other corrosive chemicals. The liner provides a non-stick, chemically inert surface that resists permeation.
PTFE Lined Column
For distillation, absorption, and extraction columns handling corrosive process media. Liner is applied to the shell and internal trays or packing support.
Custom Vessel Lining
Receivers, crystallizers, evaporators, and other vessel types lined to your drawings after process review.

Frequently Asked Questions
- Q: What is a PTFE Lined Vessel used for?
- A: A PTFE Lined Vessel is used to process or store corrosive chemicals, acids, alkalis, or high-purity fluids in a steel vessel. The fluoropolymer liner isolates the media from the steel wall, preventing corrosion, iron contamination, and premature vessel replacement.
- Q: Which vessel types can you line?
- A: We line reactors, storage tanks, distillation columns, receivers, crystallizers, evaporators, and other process vessels to customer drawings. Nozzles, manways, baffles, and internal supports can be lined as part of the same project.
- Q: What is the standard lining thickness?
- A: The standard PTFE lining thickness is 3 mm. Higher thicknesses are available on request to suit specific pressure, permeation, or vacuum service conditions.
- Q: Can you line an existing vessel owned by us?
- A: Yes. Besides supplying new lined vessels, we also line customer-owned vessels, provided the shell and internals pass a process evaluation and are structurally sound. Send us your drawing and current condition report for assessment.
- Q: Are the liners suitable for food-grade or pharmaceutical applications?
- A: Yes. Our PTFE, PFA, and FEP liners are chemically inert and we offer FDA-compliant liner grades for food, beverage, and pharmaceutical service where media purity must be maintained.
- Q: How is liner integrity verified?
- A: Each lined vessel is spark tested to detect any pinhole defects in the liner. We also perform thickness measurements at multiple points and, where applicable, hydrostatic pressure testing before shipment.
- Q: What is the typical lead time for a lined vessel?
- A: Lead time depends on vessel size, liner material, and the number of nozzles or internals to be lined. Typical delivery is 7-15 days for standard configurations, with longer schedules for large or complex vessels. Send us your drawing for a confirmed lead time.
