Stainless Steel Bare Tubes Duplex 2205 Abrasive ASTM Material ASME Standard Heat Exchanger

Stainless steel bare tubes duplex 2205 abrasive ASTM material ASME standard heat exchanger

Introduction

1)Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid.

2)We can manufacture three types of boiler economizer, bare tube economizer, H finned tube economizer and spiral finned tube economizer.

3)H-finned tube economizer is high efficient heat exchanger economizer which is consisted of H-finned tubes.

4)Compared with bare tube economizer, H-finned tube economizer can enlarge the heat exchange area and reduce the number of tubes.

5)It also can increase the flue gas flow area in order to reduce the flue gas flow speed and abrasion.
H-finned tube can be made as double H finned tubes , with high rigidness to fit long tube row.
6)The spiral finned economizer is a newly designed heat transfer equipment, consists of spiral fin tubes to overcome the serious abrasion and short service time.
