FDC

What FDC does

FDC Co., Ltd. (에프디씨㈜) is a privately held South Korean industrial manufacturer of pressure-safety and explosion-protection devices, founded in 1999 in Gimhae, Gyeongsangnam-do, by Chairman 윤하원. The company was the first Korean firm to successfully localize rupture disc manufacturing and today operates three core product lines: (1) Pressure Relief (Rupture Disc, Graphite Disc, Safety Valve, Emergency Relief Hatch, Burst Sensor, and Accessories), (2) Explosion Protection (Explosion Panel, Deflagration Panel, Deflagration Door, Flameless Venting Device, Venting Device, Burst Sensor, Accessories), and (3) Specialty Valve (N₂ Blanketing System). FDC holds ASME UD STAMP & NBBI, KOSHA, ISO 4126, and API STD 520 certifications, and as of January 2026 holds Nuclear Enterprise Certificate Gold Grade (Grade 1) and Energy Specialized Enterprise designation, qualifying it to supply directly into nuclear power and energy projects. Its products are custom-manufactured, made-to-order pressure components engineered to customer specifications (pressure rating, material, size, certification) at a 3,200+ pyeong Gimhae facility.

FDC serves enterprise customers across petrochemical/oil & gas (SABIC, ADNOC group subsidiaries, Petronas, Bloom Energy, TUNAS, WOODS PLC), nuclear power (Korean nuclear plants and Turkish nuclear EPC), shipbuilding/marine (engine manufacturers, meeting IACS UR M82), defense (Korean K9 howitzer and Chunmoo MLRS systems), semiconductor manufacturing, and emerging battery/ESS and EV applications. The go-to-market combines direct sales to large industrial accounts with a distributor network spanning 16+ countries across Asia, Middle East, Europe, Africa, and the Americas, supplemented by vendor registrations (Achilles FPAL) and active trade-show presence at InterBattery and the Korea Nuclear Industry Exhibition. FY2024 revenue was 230 billion KRW (~USD 170-175M), with a 2025 target of 270 billion KRW and a 2030 aspiration of 500 billion KRW. Average employee age is 34; total IP portfolio includes 56 registered rights plus 15 pending applications.

The business model is engineered-to-order hardware sales with multi-year contracts and quote-based pricing — there is no public price list. FDC monetizes import substitution in Korea (40-80% price advantage versus overseas equivalents per company disclosure) plus direct exports into global energy and nuclear supply chains. Customer segments are split vertically (Petrochemical, Nuclear, Shipbuilding, Semiconductor, Defense, ESS/EV), with Petrochemical & Chemical and Battery ESS as the primary revenue concentrations. Revenue is generated entirely through hardware sales of safety-critical devices, with certifications and approved-vendor status functioning as the primary qualifier for deal flow rather than any software or recurring-services layer.

Core offering

FDC designs and custom-manufactures industrial pressure safety devices and explosion protection equipment, with rupture discs as its flagship product. The portfolio spans three lines: Pressure Relief (rupture disc, graphite disc, safety valve, emergency relief hatch, burst sensor, accessories); Explosion Protection (explosion panel, deflagration panel, deflagration door, flameless venting device, venting device, burst sensor, accessories); and Specialty Valve (N2 blanketing system). Products are made-to-order based on customer specifications and serve petrochemical, nuclear, shipbuilding, semiconductor, defense, aerospace, electric vehicle, and battery energy storage applications.

Product overview

FDC is a pressure safety device manufacturer offering three main product categories: (1) Pressure Relief including Rupture Disc (the company's flagship product, first domestically localized in Korea), Graphite Disc, Safety Valve, Emergency Relief Hatch, Burst Sensor, and Accessories; (2) Explosion Protection featuring Explosion Panel, Deflagration Panel, Deflagration Door, Flameless Venting Device, Venting Device, Burst Sensor, and Accessories; and (3) Specialty Valve with N₂ Blanketing System. These products serve diverse industries including petrochemical plants, power generation, semiconductor manufacturing, shipbuilding, battery energy storage systems (ESS), electric vehicles, aerospace, defense (K9 artillery, Chunmoo MLRS), and steel mills. The company operates on a made-to-order, multi-product low-volume production model and has achieved import substitution with 40-80% price competitiveness compared to overseas products.

Products and services

• Rupture Disc Non-mechanical pressure safety device that ruptures when system pressure exceeds a predetermined level to protect pressure vessels, equipment, and personnel. Used across petrochemical, nuclear, shipbuilding, semiconductor, defense, and battery energy storage applications.
• Graphite Disc Rupture disc made from graphite material, designed for corrosive environments and high-temperature chemical and industrial processing applications.
• Safety Valve Pressure relief valve for semiconductor and industrial applications that protects equipment from overpressure conditions.
• Emergency Relief Hatch Emergency pressure relief device for rapid pressure release in industrial equipment and plant facilities.
• Burst Sensor Monitoring device that detects when a rupture disc has burst, providing real-time alerts for safety system status monitoring.
• Explosion Panel Safety device that releases pressure and flames during deflagration before detonation occurs, protecting silos, bag filters, RTOs, and bucket elevators. Available in Round, Square/Rectangular, Flat, and Dome types; KSRPR-D and KSRPR-engine models meet IACS UR M82 for ship engines.
• Deflagration Panel Explosion panel designed for battery energy storage systems (ESS) that rapidly releases combustible gases during thermal runaway to prevent explosion.
• Deflagration Door Explosion protection door for battery energy storage systems, providing structural safety by releasing pressure during deflagration events.
• Flameless Venting Device Explosion venting device that releases pressure and flames without allowing external flames, suitable for shipbuilding applications.
• Venting Device Pressure relief device for electric vehicle battery applications, enabling controlled venting of gases during thermal events.
• N2 Blanketing System Nitrogen blanketing system that maintains uniform pressure in fluid tanks to prevent explosion or deformation, used in petrochemical and industrial storage applications.
• Special Rupture Disc for Ship Engines and Emulsified Products Specialized rupture disc variants (reverse dome shear KSRRKV/KSRRKP/KSRRKU, reverse dome scored KSWSRV, VCR/PLUG/UNION fitting types) operating at 4-50 kg/cm² for ship engine and marine propulsion applications.
