APV_M-PTFE

APV is acronym
"Advanced Performance Vessel"

The best smoothness of fluororesin sheet is depending on carefully selected materials and SFS's superior lining technique and QC.

The fiberglass backing sheet remains in good condition and fully adhered to the tank wall.

The fiberglass backing sheet remains in good condition and fully adhered to the tank wall.

After 5 years, no anomalies were found in the APV experiments.

Even with highly permeation-resistant fluoropolymers, variations in permeation performance can occur.

To ensure superior performance, we conduct accelerated tests using
98percent concentrated nitric acid.

We place test tanks and panels outdoors to evaluate both material and construction quality.

After 1.5 years two summers of immersion testing, the materials and construction quality selected by SFS performed exceptionally well, maintaining excellent conditions.

Lining defect & Material Choice 01

Corrosion from the chemical has degraded the adhesive, nearing the lining's usage limit.

Lining defect & Material Choice 02

Chemical permeation, badly that the corrosion has reached the liner adhesive and is no longer at the limit of lifetime.

Example of not good product

Being a high-strength fiberglass backing sheet is one of the key performance for being a good lining sheet.

If the fiberglass backing sheet is not tightly laminated with the liner sheet layer, the lining adhesiveness cannot be ensured at curved and/or bending points. Furthermore, excellent lining technology including welding ability are required to keep the lining conformity and stability at the points particularly.

SFS lining technology and welding strength greatly enhance the reliability of the welding

SFS Tensile Test Results

Excellent lining quality

Welds do not break even at stresses that would cause the sheet to break.

The Importance of Lining Reliability

Even with excellent materials, without the support of superior lining technology, it's impossible to produce high-quality, high-performance lining vessels. Through SFS's rigorous quality control and certification mechanisms for construction technicians, we provide customers with traceable management to thoroughly monitor quality and control processes to maintain high standards.
