Fixed Tube Sheet Heat Exchanger Manufacturer in Chennai & India
KRR is a leading fixed tube sheet heat exchanger manufacturer in Chennai, supplying high-integrity FTS exchangers to refineries, petrochemical complexes, fertilizer plants and power projects across India and international markets.
Fixed Tube Sheet (FTS) heat exchangers are engineered for structural rigidity, pressure containment and long-term reliability in applications where operating temperatures and pressures remain stable. In this design, the tube bundle is permanently welded to both tube sheets, creating a leak-tight, vibration-resistant and mechanically robust heat transfer system.
KRR designs and manufactures FTS exchangers in carbon steel, stainless steel, duplex, super duplex, titanium and nickel alloys, fully compliant with ASME Section VIII, TEMA and PED requirements.
Why Fixed Tube Sheet Design?
FTS exchangers are selected when:
-
Process conditions are steady and predictable
-
Maximum pressure and temperature containment is required
-
Maintenance access is limited
-
Lifecycle cost must be minimized
They deliver low capital cost, high fatigue strength and extended service life, making them ideal for oil & gas, petrochemical, power generation and chemical processing.
