Customized ASME SA178 H-Fin Tubes High Weld Fusion Energy-Saving Carbon Steel

What are the advantages of finned tubes?

Higher heat transfer efficiency, reduced size/weight, and lower fuel consumption.

Design and development

Collect all parameters for product design, make design acording to the Supervisory Regulations on Boiler Safety Technology, other laws, rules, regulations and professional standards, and 100% meet the product standards and customers' requirements.

Product Introduction

An H-type fin tube is made by symmetrically welding two steel strips to a plain tube with an arc. The result looks like the letter “H,” and it’s a top-notch solution for increasing the heating surface, helping you save energy big time.

These tubes are stacked with benefits: high weld fusion rate, strong tensile strength, low contact thermal resistance, excellent heat transfer, and great expansion ability. When used to build an H-type economizer, it ends up with high heat exchange efficiency, low flow resistance, minimal wear, and a lightweight design. Compared to regular fin tubes and spiral ribbed tubes, H-type fin tubes can expand the heating surface to the max.

One more win: for the same heat exchange performance, an H-type fin tube economizer takes up far less space. And it’s not just for economizers—you can use them to make H-type evaporators, superheaters, heaters, and more. That’s why they’re listed in China’s High-tech Product Catalog.
