Boiler Pressure Parts (Economiser)

Boiler Pressure Parts-

  • Economiser

Economizer coils are used in downstream of Boiler bank to preheat the feed water absorbing heat from hot exhaust gases.Economizers have different types of Tubes depending upon the application. Bare tubes in Economizers are widely used in Industrial boilers and for applications like Heat recovery boilers in Sulfuric acid plants, gilled tubes are employed. Finned tubes are popular in HRSG applications.

Material of Construction: Carbon steel / Alloy Steel (Seamless Tubes / ERW)

Types of Economisers-

  1. Bare Tube Economiser Coils.
  2. Grill Tube Economiser Coils.
  3. Finned Tube Economiser Coils.

Key highlight of our Economisers -

  • We conduct 100% radiography of all welded joints.
  • Our grill Economisers & Finned Tubed Economisers have found wide acceptance in overseas countries.
  • We can fabricate economisers with bends having D/R ratio of less than 0.67
  • We can bend pipes upto 12”NB using cold bending process

Boiler Pressure Parts (Superheater)

Boiler Pressure Parts-

  • Superheater

Super heaters are used to convert saturated steam or wet steam into dry steam used in industrial processes. Super Heated steam produced in the super heater is then used to produce electricity in captive power plants or is used to suffice complex process requirements.

Material of Construction: Stainless steel / Alloy Steel (Seamless Tubes ).

Types of Super Heater

  1. Radiant Super heater.
  2. Convection Super Heater .

Key highlight of our Super Heaters-

  • We conduct 100% radiography of all welded joints.
  • Proficiency in dissimilar welding.
  • Ability to manufacture close radius bends using cold bending process.
  • Experience in manufacturing studded welding on super heater coils.

Boiler Pressure Parts (Evaporator)

Boiler Pressure Parts

  • Evaporator / Studded Pipes

Almost all AFBC/ bubbling bed boilers use in-bed evaporator tubes in the bed of limestone, sand and fuel for extracting the heat from the bed to maintain the bed temperature. Evaporator is the device where water is converted into saturated steam in AFBC Boilers. Most commonly evaporator coils have studs welded on them to increase surface area in contact with the bed thereby increasing efficiency of the device.

Material of Construction: Carbon steel / Alloy Steel (Seamless Tubes )

Types of Evaporator Coils-

  1. Plain Evaporator Coils.
  2. Studded Evaporator Coils.

Key highlight of our Evaporator Coils-

  • We conduct 100% radiography of all welded joints (if any).
  • Proficiency in dissimilar welding.
  • Proficiency in studding 12 studs per plain.
  • Ability to perform studding on close radius bends.
  • Ability to undertake studding between dissimilar metals (Eg. SS Stud on CS Pipes).

Heat Exchanger

Heat Exchanger

Tube in Shell Type Heat Exchangers:

Tube in Shell Type Heat Exchangers are the most common type of heat exchanger in oil refineries and other large chemical processes, and are suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes to transfer heat between the two fluids. The set of tubes is called a tube bundle,

FAB PRECISION offers below range of tube bundles

  • Plain tube bundles.
  • Longitudinal Finned tube bundles.

Key highlight of Heat Exchangers manufactured by us

  • We conduct 100% radiography of all welded joints.
  • Experience with wide range of material ( Carbon steel/ SS/ Titanium Alloys/ Copper Alloys ).
  • In house facility for baffle plate machining & shell fabrication.
  • Complaisance with TEMA standards.

We also offer range of spares used in efficient operation of Tube & shell Heat Exchangers.
