Steelfab Water Solutions imports two different materials for manufacture of liners for its tanks. Both these materials are exclusive to Steelfab. All Liners meet the stringent AS/NZ 4020 standards for portable water storage.
0.55 mm to 1 mm thick PVC liners are used depending upon the size of the tank and the application.
WE have manufactured and installed liners upto 20 mts in diameter and 6 mts in height. Because we use PVC, our weld becomes the strongest part of our liner.
Why PVC?
PVC (Poly Vinyl Chloride) is 1.8 times the strength of HDPE / LDPE so our 0.55 mm thick liner is equal to 1.0 mm thick material. Our 0.8 mm thick PVC is equal to 1.5 mm thick of HDPE / LDPE. At the same time, PVC is flexible and will conform to any shape or contour which means no folds or creases to catch on equipment. PVC will take up higher or lower temperatures than HDPE / LDPE.
PVC is permanently repairable wet or dry without special tools or training. PVC is the only material that truly welds together. The weld penetrates right through the material, not just the top surfaces.
