Vipertex enhanced heat transfer tubes are produced according to ASTM 249 standards. Certification under ASTM 249 standards covers the production of cold worked, welded tubes that are intended for boiler, condenser and heat exchange designs.
Enhancement of heat transfer using Vipertex ® tubes is produced from a combination of secondary flow generation, increased turbulence, boundary layer disruption, increased heat transfer surface area and an increased number of nucleation sites; all leading to an enhanced heat transfer performance for a wide range of conditions.
Highlights Enhanced heat transfer tubes were developed using Vipertex surface designs. Increases in the overall heat transfer occur as the result of increased surface area, the disruption of the boundary layer and an increase of fluid turbulence. Vipertube designs cause secondary flow patterns to develop which minimize the rate of fouling occurring on the tube.

Popularly, they are well-known as 'Shell Boilers', since all the surfaces in these boilers that contribute heat transfer are enclosed. The operation of fire tube boiler is as simple as its construction. In a fire or smoke tube boiler. Learn More
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
7）It takes the screw thread smoke tube to enhance heat transfer, improve the heat transfer coefficient and thermal efficiency, due to disturbance of smoke in the tube. The smoke pipe is not easy to accumulate dust, it can clean by itself. Eight character wall in the furnace, smoke window outlet all have effect of dust fall.

Totally new design industrial grade construction, 2 pass fire tube design with enhanced heat transfer features. The VIX Series can offer higher efficiencies than standard vertical boilers. It is 100% water-backed and built for years
Fire-Tube Boilers (FTB) are the most common heating devices that transfer heat from the combustion gases (flue gases) to water in order to have hot-water up to 3000 kW or saturated steam ranging up to 25 ton/h at 25 bar. In fire tube boiler, the furnace is filled with flame and hot gases, while tubes are filled with hot gases. These tubes and

boiler heat transfer and efficiencies than plain tube boilers that have the total 359 sq. ft allowed in such boilers. Due to the increased heat transfer from X-ID tubes, X-ID boilers are more efficient than plain tube boilers producing the same output leading to significant fuel savings.
to use enhanced tubes to improve heat transfer performance in an MSF system. The current study is primarily concerned with the enhancement of MSF performance when replacing a smooth tube with a corrugated one.
