Boiler Super Heater Coils
TPP Boilers Pvt. Ltd. 
(Tubes, Pipes, Boilers for Thermal Power Plants)

We avail this opportunity and take pleasure in introducing TPP Boilers Pvt. Ltd. as a Designer, Fabricator & Erectors of Boiler Components & Equipments made of steel plates or tubes or pipes.

We are a small scale industry promoted by our good experienced CEO and CTO with workers participation all separated from an old (over 50 years) established Boiler Manufacturing and Erection Company. Hence we offer the expertise of a very Large Company with accessibility of a small company at very Reasonable Costs.

Our Promoters and Promoter Workers have a very deep knowledge and wide experience of over 500 man-years in Fabrication, Erection, Bending & Welding of all kinds of Plates, Sections, Tubes and Pipes like Seamless, ERW, and Rifle-Bore made of any kinds of Steels like Carbon Steels, Alloy Steels, and Stainless Steels in any Size and Length and to any Specification.

Economisers Coils

Superheaters Coils

Studded Tubes / Coils

Boiler Bank Tubes

These are boiler feed-water heaters in which the heat from waste flue gases is recovered to raise the temperature of feed water supplied to the boiler, thereby increasing the Fuel Economy, Steaming Capacity, Life of the Boiler and Reducing Pollution.

Superheaters Coils are the most critical Boiler Component of the modern day Thermal Power Plant and are subject to very high metal temperatures. In fact the capacity of the Superheater to work without failure at higher Temperatures is what determines the boilers Capacity and it effects improvement in economy by reducing Steam Consumption of the Steam Turbine.

Studded Tubes are used to increase the Surface Areas to achieve higher Heat Transfer Rates. They are used in Fluidized Bed Coils and Fluidized Bed Superheaters. They are also used in Refineries as Reheaters.

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.

Water Wall Panels

Pipes & Tube

Helically Wound Finned Tubes

Finned Tubes
Water Wall Panels are used in modern day Boilers in place of Steam Generating Tubes to reduce heat loss due to their gas tight nature and reduce insulation costs. We fabricate Water Wall Panels using automatic Fin to tubes welding machines and large Tube Panel Benders to achieve desired shape of panels which can have Swaged Ends, Stub Welded to Headers. We supply Panels with integrated manhole openings in the panels.

We supply steel pipes, tubes & fitting to various specification with MTC & IBR Certificate In the size range of 8 mm OD to 1016 mm OD x 1 mm Thk to 76.2mm Thk used for steam / line piping, boilers superheaters, economizers, water wall, headers, air pre heaters, Heat exchanges, rifle bore tubes etc.

Steel pipe & tubes are classified by the following methods:

 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.		 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 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. 

Headers

Heat Exchangers

    
Headersform 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. For pressure vessels and reaction vessels in M.S., Al, Monel, Inconel, Cupronickel, etc., Tube Weld employs the latest techniques for expanding tube ends into tube sheets. High pressure tests are always carried out on these heat exchangers before they leave the factory. Brass, copper, M.S. and S.S. tube sheets are used.Tube sheets are also made out of mild steel, alloy steel or stainless steel and baffle plates are made out of mild steel or stainless steel.
