We  manufacturers of double pipe heat exchangers in India. A double pipe heat exchanger like Shell and Tube Heat Exchangers. We provide high and international quality standards double pipe heating system. We using latest raw material in the making development of double pipe heat exchangers.


This type of heat exchangers are mostly used in the fields of Thermal Power Station, petroleum and Heat Industry, Oil and food Plants, Power Stations and etc.

Features of Double pipe heat exchanger: High Efficiency, International high quality, Low Maintenance Cost, Quick Heat Transfer.

Double pipe heat exchanger Calculation: We are using most excellent softwares for support of complicated calculations while design of double pipe heat exchanger.

Double pipe heat exchanger Design : Heat Transfer Equipments Pvt Ltd used top rated softwares to design and best quality design engineers to design your double pipe heat exchanger. The heat exchangers are usually designed in a hairpin shape with ASME Code and will typically be either counterflow or parallel flow.

1. ASME (American Society of Mechanical Engineers) ASME Code

2. TEMA (Tubular Exchangers Manufacturers Association)




The heat exchanger is completed of concentric inside also exterior pipe and the Heat exchangers are used to transfer the energy from one substance to another. This Heat system structure is simple and heat transmission is big.

Thermal design Calculation
