| Rubber Lining Thickness range is 4 MM to 8
MM |
Polypropylene is not lining and therefore
Polypropylene
thickness range is 10 mm to 40 mm |
| Lining is done manually and therefore it has human error. |
Welding is automatic and there fore it is reliable. |
| Life 5 to 7 years. |
Life 15 to 20 years |
| Ageing of rubber lining happens resulting in to cracking,
rigidity of rubber, brittleness which gives failure. |
Polypropylene have no ageing effect. |
| During leakage of lining iron get dissolved and liquid
get contamination, M.S. tank get corroded. |
Polypropylene tank does not have iron tail. leakage can
be seen no iron contamination, no corrosion. |
| Location joint failure in rubber lining is difficult. |
Locating leakage is very easy. |
| Ms rubber lined tank is heavy in weight. |
Polypropylene tank are lighter in weight and they
are mobile. |
| Rubber is lined and they are lined in ms tank. |
Polypropylene is not lined in tank. Polypropylene itself
is tank in mild steel skeleton frame. |
| Rubber has porosity. |
Polypropylene is solid and non porous material. |
| Rubber is soft material. |
Polypropylene is hard and rigid material. |
| Easily get damaged. |
Very difficult to get damaged. |
| Virginity of rubber is questionable. |
Polypropylene can be easily identified and tested for
virginity. |
| Surface preparation and clean Surface is crucial for
adhesion. |
Polypropylene is not being adhered to m.s tank |
| Joint blistering is common problem. |
There is not overlap joint. no blister. |
| Require full support of mild steel. |
Polypropylene require only skeleton frame. |
| Disbanding and air pocket is a regular problem.. |
There is no bonding, no air pocket in Polypropylene
welding. |
| Rubber is bonded by adhesive. |
Polypropylene is not bonded by adhesive. tank is made out
of P.P. it self |
| Sand blasting can not be compromised. |
Sand blasting not required. |
| Heat loss missed |
Heat loss is very less. |
| It require regular maintenance |
It is maintenance free. |
