Korea Cast Iron Pipe Industry Set for Growth as Doosan Secures More Gas Turbine Orders... Large Cast Steel Supply for Power Generation Accelerates

Korea Cast Iron Pipe Industry is gaining attention as a key beneficiary in the large cast steel market for power generation, thanks to the expansion of Doosan Enerbility's gas turbine business. As the gas turbine market grows in response to increased electricity demand driven by the spread of artificial intelligence (AI) data centers, the supply of core materials is also expected to expand.

Korea Cast Iron Pipe Industry manufactures large cast steel components used in power generation facilities, and the increase in gas turbine orders from its major client, Doosan Enerbility, is emerging as a new growth driver for the company's performance.

In the first quarter of this year, Doosan Enerbility secured orders for a total of 10 gas turbines, including three units in Korea and seven units in North America, marking the start of a full-fledged growth phase. Recently, the company signed a long-term parts supply contract worth 480 billion won with Korea Southern Power for three gas turbines at the Goyang and Hadong power plants. These power plants are scheduled to begin commercial operation in December 2029.

The increase in gas turbine orders leads to greater demand for related parts and materials. Korea Cast Iron Pipe Industry supplies large cast steel components for power generation equipment, including turbine casings—which are key structural parts that maintain and protect internal pressure within turbines—as well as valve bodies, butterfly valves, and gate valves.

In particular, because gas turbines operate for long periods under high-temperature and high-pressure conditions, there is a constant need for regular maintenance and replacement of parts. As a result, the company expects to secure a stable demand base not only in the supply of new equipment but also in the maintenance market.

Large gas turbines are considered high value-added products, with only five companies worldwide—including Doosan Enerbility—capable of producing them. Recently, the global gas turbine market has been experiencing accelerated growth due to surging electricity demand from the expansion of AI data centers.

To meet increasing demand, Korea Cast Iron Pipe Industry plans to complete a dedicated gas turbine plant by the end of July. The remodeled facility, converted from an existing plant, will be capable of handling the annual production volume of up to 10 gas turbines.

After the dedicated plant begins operation, the company expects to further expand its supply capacity in the power generation sector and gradually increase the proportion of power-related sales within its total cast steel revenue.

A representative from Korea Cast Iron Pipe Industry stated, "The expansion of the gas turbine business by major clients, including Doosan Enerbility, is driving up demand for large cast steel products used in power generation," and added, "With the completion of the dedicated gas turbine plant in July, we plan to further strengthen our supply competitiveness in the power sector."

As electricity demand rises due to the proliferation of AI data centers and the global gas turbine market continues to grow, Korea Cast Iron Pipe Industry is expected to enter a new phase of growth by expanding its supply of core cast steel products for power generation and operating its dedicated plant.
