Heat Exchanger Straight Tubing

Heat exchanger tube, heat exchanger is widely used in chemical industry, petroleum industry, electric power industry, food industry and many other industries.

Heat Exchanger Straight Tubing Features

A heat exchanger is a device that transfers heat energy from one fluid to another. The heat of a high-temperature object is always transferred to a low-temperature object. In this way, the heat on the hot side is exchanged to the cold side. Sometimes we call it a heat exchanger. Heat exchange tube is an important part of transporting fluid in heat exchanger. Our heat exchanger tube, alloy 625 HE tube has superior surface finish, better mechanical property, more precise dimension, perfect inspection method and inspection equipment
