Road tankers are used all over the world for transportation of water, edible oil, milk, chemicals and petroleum products.
Traditionally, road tankers have a steel or aluminium body, with or without rubber lining inside. Metallic tankers are heavier
with 12 to 15% of the liquid they carry and the rubber lining requires frequent repair and relining every four years. Unlike
pressure vessels, road tankers for transportation of liquids under gravity are made of double-‘D’-shaped cross-sectional
profiles in order to keep the overall centre of gravity low for better stability and vehicle road holding. No winding process for
such non axi-symmetric profiles with integral-end dome winding has been developed so far. This innovation is intended for the
filament winding of such tankers.
These composite tankers are more resistant to water and many chemicals. Their high strength-to-weight ratio and stiffness-to-
weight ratio make them lighter and long lasting. They offer 45% weight saving over a steel tanker. The jointless winding of
shell in an automated machine makes production faster and the product stronger. Two tankers can be made in a day vs.
several days for steel. A factor of safety of six or above is guaranteed without any resin leakage.
In September 2008, the AMC approved the launching of the tanker for field application. Negotiations are in process with a
major truck manufacturer in India for marketing the product with annual initial sales of 500 tankers.
