ABSTRACT:
A heat exchanger includes banks of double-pipe elements connected to oval headers, the opposite ends of which are connected by round transition elements to main headers. Each oval header and the respective transition elements are formed from a single, integral member, initially a cylindrical pipe, without connecting welds. The outer ends of the transition elements are reduced to form nipple elements for attachment to the main headers. The nipple elements have a greater wall thickness than the transition elements.
