TURMASOL gas turbine transition piece

The TURMASOL transition piece is the duct in an industrial gas turbine combustion system that converts the round combustor section into the sector-shaped inlet of the first turbine stage, made from heat-resistant alloy sheet by forming and welding.

Manufacturer: TURMASOL (Turmasol Co., Ltd.), Korea, founded January 2012, factories in Gimhae, Gyeongsangnam-do, specialising in precision sheet-metal components in heat-resistant alloys. FEYANA supplies TURMASOL products in Vietnam to customer drawings and technical requirements.

Quick facts

Function

The transition piece carries high-temperature combustion gas to the first-stage nozzle under high thermal stress and vibration; it is routinely inspected, repaired or replaced in hot gas path overhauls.

Manufacturing technology

• Machining and welding of high-temperature alloys
• Heat and fluid-flow analysis to optimise combustion efficiency
• Heat treatment and non-destructive testing (NDT) for large components

Fabrication process

Laser/waterjet cutting → press forming → single-piece machining → welding/brazing assembly → vacuum heat treatment → final machining → mechanical joining (riveting, bolting) → final inspection (FPI, CMM, vision measuring).

Manufacturer certifications

• AS9100 and ISO 9001
• NADCAP: heat treating, NDT (FPI), nonconventional machining (EDM), welding
• KS Q 9100

Applications

• Simple and combined-cycle power-generation gas turbines
• Industrial gas turbines in oil & gas and chemicals
• Transition piece replacement during overhauls

FAQ

What is a transition piece?

It is the duct carrying combustion gas from the combustor to the first turbine stage of a gas turbine.

When should a transition piece be replaced?

It is usually assessed during hot gas path inspections and replaced when cracking, distortion or wear exceed the turbine OEM limits.
