Introduction

Description of Spiral Finned Tubes:
The spiral fin steel pipes currently used are mostly wound, high frequency welded and brazed spiral fin steel pipes.

The advantages of spiral fin steel pipes are as follows:
1. Long service life, is more than 20 years;
2. The surface of the fin is smooth, and it is not easy to produce ash accumulation, ash blocking and slagging.
3. It has good density, yield strength, tensile strength and wear resistance of metal structure.
4. The welding quality is high, so that it is not easy to cause unstable heat transfer performance because of fin loosening and falling off.

Application of Spiral Fin Tubes:
Waste heat boiler tube;
Economizer tube;
Power station boiler tube;
Marine boiler tube;
Heat exchanger

Technical parameter

Medium air, flue gas, thermal oil, water, brine, refrigerant, etc.
Temperature standard heat exchanger to 560 ° C by special materials can be higher
Pipe materials carbon steel, stainless steel, alloy or special materials
Ribs materials carbon steel, stainless steel, non-ferrous metal, alloy or special materials
Thermal insulation &Surface treatment according to customers specification

Features

Features

1. The equipment body can be designed into many modules to ensure the long term and stable running.

2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage.

3. Improve the heat transfer efficiency.

4. Structure arrangement: In line or staggered arrangement.
