Gas turbine power plants — whether operating in simple-cycle configuration for peaking and fast-response power supply, or combined-cycle configuration pairing the gas turbine with a heat recovery steam generator and steam turbine to extract additional efficiency from the gas turbine's exhaust heat — present component demands genuinely distinct from steam-cycle-only or hydroelectric power generation equipment, centered on the gas turbine unit itself and its supporting balance-of-plant systems. The gas turbine's casing components (compressor casing, combustor casing, turbine casing) must maintain precise internal geometry and structural integrity while containing internal pressures and withstanding the substantial thermal gradients a gas turbine's operation creates, from relatively cool inlet air compression through to extremely high combustion and turbine section temperatures, all while supporting the compressor and turbine section rotating assemblies with the dimensional precision efficient turbine operation requires. This combination of pressure containment, precise structural geometry, and demanding thermal service places gas turbine casing and structural forgings in a genuinely distinct category from the flange and piping forgings common to power plant balance-of-plant systems generally, warranting material grades and manufacturing quality specifically suited to gas turbine operating conditions — a more specific application than power generation forging demand considered broadly across steam, hydro, and gas turbine plant types together.
Forged casing and structural components for gas turbine compressor sections, supporting the precise internal geometry and structural integrity compressor operation requires while containing the section's operating pressure.
Forged casing components for combustor and turbine sections, engineered for the substantial thermal gradients and elevated-temperature structural demands these sections experience during gas turbine operation.
Forged structural components supporting turbine section assembly and rotating element containment, addressing the combination of high-temperature material demands and precise dimensional requirements this section involves.
Forged flange, fitting, and valve body components for heat recovery steam generator (HRSG) and associated steam system piping in combined-cycle gas turbine plant configurations, supporting the balance-of-plant systems extracting additional efficiency from gas turbine exhaust heat.
Material grade selection accounting for the substantial thermal gradient a gas turbine's operation creates across its sections, from compressor inlet conditions through elevated combustor and turbine section temperatures, matched to each component's specific location and thermal exposure.
Manufacturing quality supporting the structural reliability casing and structural components require under the combination of internal pressure containment and substantial thermal cycling gas turbine operation imposes, particularly through start-stop cycling for units in cycling or peaking service.
Precision machining supporting the dimensional accuracy structural components need to properly support and align compressor and turbine section rotating assemblies, directly relevant to overall turbine operating efficiency and mechanical reliability.
Complete dimensional inspection and material certification, supporting the quality documentation gas turbine OEMs, EPC contractors, and plant operators require for these safety-critical, high-temperature power generation components.
Gas turbine power plants occupy a genuinely distinct position within power generation infrastructure, valued for the combination of relatively fast startup and load-following capability that makes them well suited to peaking and flexible power supply roles, and for the substantial additional efficiency achievable in combined-cycle configuration, where a heat recovery steam generator captures thermal energy from the gas turbine's exhaust to raise steam for a supplementary steam turbine, extracting meaningfully more electrical output from the same fuel input than a simple-cycle gas turbine alone would achieve. This plant configuration — whether operated in simple-cycle or combined-cycle form — centers on the gas turbine unit itself, a machine whose operating principle (compressing inlet air, combusting fuel with that compressed air at high temperature, and extracting mechanical work from the resulting hot expanding gas through a turbine section) creates component demands genuinely distinct from steam-cycle-only or hydroelectric power generation equipment.
The gas turbine's casing components — compressor casing, combustor casing, and turbine casing — sit at the center of these distinct demands, since each casing must simultaneously maintain precise internal structural geometry supporting the rotating compressor or turbine assembly within it, contain the section's internal operating pressure, and withstand the substantial thermal gradient the turbine's overall operation creates across its length, from relatively moderate compressor inlet air temperature through to the very high temperatures combustion and the subsequent turbine section involve. This combination of pressure containment, precision structural geometry, and demanding elevated-temperature service is genuinely distinct from the requirements governing typical power plant balance-of-plant flange and piping components, and it places gas turbine casing and structural forgings in a category warranting material grade selection and manufacturing quality specifically matched to gas turbine operating conditions, including the particular thermal cycling demands units in cycling or peaking duty experience through repeated start-stop operation.
For combined-cycle plant configurations specifically, component demand extends beyond the gas turbine unit itself into the heat recovery steam generator and associated steam system balance-of-plant, which requires its own set of flange, fitting, and valve forgings supporting the steam piping system that captures additional efficiency from the gas turbine's exhaust heat — components with more conventional high-temperature steam service material requirements, distinct from but complementary to the gas turbine's own casing and structural component needs. Together, this makes gas turbine power plant component sourcing a genuinely specific engineering application within the broader power generation forging category, benefiting from a supplier capable of addressing both the gas turbine unit's demanding casing and structural forging requirements and the balance-of-plant piping requirements combined-cycle configurations add.
For gas turbine OEMs, EPC contractors, and plant operators sourcing forged casing, structural, and balance-of-plant components, Shivam Forge provides material selection matched to your plant configuration and specific component thermal service.

This page focuses specifically on components for gas turbine units themselves — casing, compressor, and turbine section structural forgings — and the combined-cycle balance-of-plant piping specific to gas turbine plant configurations. Our broader power generation forging page covers a wider range of power plant equipment across thermal, hydroelectric, and general power infrastructure applications, including components not specific to gas turbine technology.
Gas turbine casings must maintain precise internal structural geometry while containing operating pressure and withstanding the substantial thermal gradient the turbine's operation creates, from cooler compressor inlet conditions through much higher combustor and turbine section temperatures — a combination of pressure containment, precision geometry, and thermal demand distinct from general balance-of-plant piping and flange components.
The gas turbine unit's own casing and structural components face similar demands in both configurations. Combined-cycle plants add balance-of-plant requirements beyond the gas turbine itself, specifically for the heat recovery steam generator and associated steam system piping that captures additional efficiency from the gas turbine's exhaust heat — components not present in a simple-cycle-only plant configuration.
