Spiral Fin Tubes Dealers in Mumbai

Fins are basically external surfaces on tube for increasing the surface area of the bare tube, resulting in a compact Heat Exchanger.  The method of attaching the fins over tube is of prime importance, since even a slightest air gap between the tube and fins will defeat the whole purpose of fins over the tube. Considering the above facts Heft has indigenously designed and developed a special purpose tube fining machine capable of producing following types of finned tubes. HEFT was formed in 1994 to provide the service to petrochemicals, power generation, chemicals, pharmaceuticals industries with high quality HELICAL WOUND FINNED HEAT EXCHANGERS tubing used in the maintenance and manufacture of the air cooled heat exchangers, air heaters & other related heat exchangers. Finned tubes are able to even out the heat transfer between the inside of the tube and the outside. When the heat transfer coefficient on the outside of the tube is significantly lower than the heat transfer coefficient on the inside of the tube, there is a major advantage to incorporate fins on the outside tube surface to take full advantage of the high heat transfer rate on the inside of the tube. By using a finned tube with eight times as much surface on the outside of the tube, the total length of the tube required for heating the viscous oil can be reduced by one sixth, Fins are basically external surface on tube for increasing the surface area of the bare tube, resulting in a compact heat exchanger. 

While it is not necessary to tell engineers what finned tubes are, or that their use is mandatory in cases of gas-liquid heat exchange where the film coefficient ratio is above 2, it is essential to tell the engineers that M.J.Patel's FINNED TUBES are backed by not only engineering excellence of manufacture, but also by our zealously guarded reputation for the finest quality of all our products. T-FINS Helical Straight strip wound on the tube are mechanically secured. The tubes are required grade of steel, the fins are aluminium for maximum tube-wall temperature of 121 deg C (250 deg F) and mild service conditions.L-FINS Helical strip bent to L-shape are mechanically secured to the tube with the outer surface of the tube totally enclosed with fins, for full fin contact and protection of tube from chemical action of the gas for maximum tube-wall temperature of 177 deg C (350 deg F) and moderate service conditions.G-FINS Helical straight strip wound into pre-cut grooves on the outer wall of the tube, fin and groove lips mechanically closed for maximum tube-wall temperature of 371 deg C (700 deg F) and extreme working conditions. STUDDED TUBES We have developed state of the art Technology for studded Pipes and Tubes of Carbon, Alloy and Stainless Steel Material having extremely low clear gaps between studs. These are used in Refinery Services and Fluidized Beds Boiler Coils.LONGTITUDINALLY FINNED TUBES We have indigenous developed automatic welding machines for giving low distortion Longitudinally welded Finned Tubes used in low capacity Boilers. MAJOR APPLICATIONS Process liquid cooling, Water cooling in chemical, petroleum, petrochemical and similar uses, Condensing, etc. Heating of air by steam in tubes. Air-conditioning and refrigeration industries, Metallurgical industries for cooling of quenching oil.
