Precision equipments are one of the heavy industries in India. we manufacture a double pipe heat exchanger that has one-pipe held concentrically cover inside by the larger pipe. The inner pipe acts as the conductive barrier, where this barrier physically separates the flows but enables the transfer of heat energy, wherein one side of fluid flows through this inner pipe and it gets to flow through the outer pipe. This double pipe heat exchanger is intended to allow two flows to communicate. By this double pipe heat, exchangers may help as multi-purpose, while during the time of using it should have a quality standard. we Precision equipments, manufacture such a quality of heat exchanger and supplies anywhere in India, USA. The materials that we used only quality standards and durability of the products have a long life.
