HDPE Concrete Liner Sheet, internal lining of piping applications for corrosive chemicals

Features

1. Very good resistance to corrosive chemicals, gases such as hydrogen sulphide, acids, alkalis, and highly offensive salts.
2. Permanent bonding to concrete substrates prevents de-lamination due to high groundwater backpressure.
3. Unaffected by constant exposure to high humidity and water.
4. Strong sanitary bacteria and ever-growing fungus do not affect the T-Lining.
5. Highly effective resistance to gas penetration.
6. Joints are heat welded to form a continuous lining over the entire structure.
7. If damaged, it can be repaired quickly and easily by removing the damaged area and welding another piece in its place.
8. Flexible liner is able to bridge cracks in the structure without peeling of the T-Lining material.
9. SanGrip T-RIB remains flexible within a wide temperature and between 75 degree C and 40 degree C.
10. Can be welded at any time over its lifespan using a variety of Welding methods: Hot air Fusion – Speed weld/ Hot wedge type/ Extrusion type.
11. Can be used as As a Tank Lining : ideal for a wide range of chemicals and can withstand continuous immersion up to 71 degrees C, but upper temperature limits depending on type and concentraton of materials.
12. Dielectric Strength: SanGrip T-RIB is a non-conductor of electricity and resists electrolysis. The dielectric strength of the basic resins [using ASTM D149 test method, short time test] is 400-850 volts per Mil (25 Microns) of thickness. 
13. Water Absorption Rate : (% change maximum in original weight) to ASTM D 570. Results are 0.1% over first 24 hours then the rate drops rapidly. Total absorbed amount is not increased over prolonged period.
14. Water Vapour Transmission Rate : Using ASTM E96 test method, [38 degrees C and 100% relative humidity] the transmission rate is about 0.020 (per 100 square inches per day) for 1.5mm thickness sheet.
15. Co-efficient of Linear/Thermal expansion : ASTM D696 Test method gives a rate of 1.2 x 10-4 per degree C rise in temperature. SanGrip T Rib Liner Sheets do not exhibit significant contraction / expansion differentials to concrete.
16. Hardness – Shore Durometer 'D' is 55 at 25 degrees C. (ASTM D 2240 test method).
17. Tensile test of T-RIB lining/Weld Strength (ASTM D638 Test Method):  
18. Mainline Sheet : Average around 3600 psi (25 N/MM2) Field Weld All type
19. Shear Test: Parent material fails before weld.
20. Elongation of T-RIB Sheet : From 600% for HDPE to 900% for LLDPE and special resin HDPEs.
21. Abrasion Resistance : ASTM D1044 test method. Wheel CS17 with loading of 1 kilogram. Weight loss is around 18mg per 1000 cycles. 
22. Coefficient of Friction: To ASTM test method D1894; static value 0.74Kinetic Value : 0.55
23. Specific Gravity  (ASTM D792) : Specific Gravity for LLDPE is 0.92. Specific Gravity for HDPE is 0.93 .
24. Tear Resistance (ASTM D1004 Die C) : Test Method - Thickness 1.82 mm /Average 300N.
25. Low Temperature Brittleness (ASTM D746 ) : Test Method : -94 degrees F.
26. Modulus of Elasticity (Secant Modulus) : Expressed in Pounds per square inch.: 15,000 psi for LDPE and 25,000 psi for HDPE 
27. Chemical Resistance : After conditioning to constant weight at 43 degree C (110 degree F) tensile specimens and weight change specimens shall be exposed to the following solutions for a period of 112 days at 25 degree ±3 degree C(77 degree ± 5 degree F).
28. At 28-day intervals, tensile specimens and weight change specimens shall be removed from each of the chemical solutions and tested. If any specimen fails to meet the 112-day exposure, the material will be subject to rejection.
