BOILER BANK TUBES

Boiler Bank Tubes are Bent to Shape Tubes or Steam Generating Tubes where Water is converted to Steam. Boiler Bank Tubes carry a mixture of water and steam. Fabricated from Tubes in various sizes and shapes, bending of these tubes is generally to larger Radius hence they need some Tube Bending Expertise to avoid wrinkles, surface cracking, irregularities, ensuring long life of tube resulting in smooth and efficient operation of the Boiler. These tubes for replacements in boilers have been supplied by us to various industries like Sugar, Refineries Steel Plants, small and Large Utility / Captive Power Plants. These Shaped Tubes are generally fabricated from Seamless/ ERW Tubes. The sizes of tubes having different shapes vary from 114 mm OD. X 4 mm Thk. to 50.8 mm OD. X 5.60mm Thick with or without Swaged Ends and with or without Welded Fins and with Wrap.

HELICALLY WOUND FINNED TUBES

G Fins:  (Embedded Fin) The G fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures. Maximum operating temperature for this fin type is 450°C. Fin Material: Aluminum or Copper

Tube Materials: Carbon steel, Cr.-Mo. Steel, Stainless Steel.

L Fins:  L Fin strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maximizing the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube. Maximum operating temperature for this fin type is 150°C.

Fin Material: Aluminum or Copper.

Tube Materials: Carbon steel, Cr.-Mo. steel, stainless steel

Crimped Fins:  This fin type (crimped fin) is a non taper fin wrapped under tension around the base tube. The finning process results in a crimp forming at the foot of the fin. Fin is then welded to the base tube at the strip ends. Maximum operating temperature for this fin type is 250°C.

Fin Material: Carbon/Stainless Steel or Copper.

Tube Materials: Carbon/Stainless Steel.

HEADERS

Headers form an important part of all types of boilers. Steam from the generating tubes is collected in headers which are therefore always under pressure. This pressure may vary from 300 psi to 2000 psi. Since headers are always under pressure, the utmost care is taken by us while fabricating them. Depending on the generating capacity of the boiler the header sizes fabricated by us vary from 100 mm to 600 mm NB. The stubs of various sizes are very carefully welded to the main body of the header to provide the desired openings from the headers.

Bevelling and weld preparation of stubs duly tack-welded to the main body of the header are first shown to Chief Inspector of Boilers for his approval and once again the stubs fully welded with main body are shown to Chief Inspector of Boilers under hydraulic pressure, varying from 1000 to 3000 psi as required by the specifications. The headers are stamped by Chief Inspector of Boilers before they leave our manufacturing plant. We also weld skubolets and weldolets in place of stubs.
