Business Areas

• High-Frequency Induction Bending: This is a core business area where pipes are locally heated using high-frequency induction coils and then precisely bent to the desired angle and radius. This technology minimizes welding areas, maximizing the stability of piping systems and fluid flow efficiency, and is applied in the production of critical piping for power plants and gas plants in high-temperature, high-pressure environments.
• Shop Prefabricated Piping Manufacturing: We primarily produce shop-fabricated piping, which is essential for various plant industries such as nuclear power, thermal power, marine, and gas lines. We provide high-precision piping solutions for critical infrastructure industries that demand the highest level of quality and safety, having supplied approximately 94% of domestic natural gas supply pipelines.
• Steel Pipe Fittings and High-Frequency Bands: We perform pipe manufacturing, including steel pipe fittings and high-frequency bands, and supply pipes of various materials processed to precise curvature radii and angles according to customer requirements.

Products

• High-Frequency Induction Bending Pipe: This is a bending pipe precisely manufactured using a high-frequency induction heating method. It is made from various materials such as carbon steel, alloy steel, and stainless steel, and compared to conventional methods, it has a lower thickness reduction rate and minimizes changes in the mechanical properties of the material.
• Shop Prefabricated Piping Spool: This is high-quality shop-fabricated piping applied in various plant industries such as nuclear power, thermal power plants, offshore plants, and shipbuilding. Even complex piping lines can be manufactured as a seamless, integrated unit, offering high design flexibility.
• High-Frequency Bending Equipment: We secured technology by localizing high-frequency bending machines for the first time in Korea, and we manufacture bending equipment applicable to pipes from small to large sizes.

Special Notes

• Unrivaled High-Frequency Bending Technology: In 1981, we successfully localized high-frequency pipe bending machines for the first time in Korea, boasting world-class technology. We possess the technology to stably bend large pipes with diameters of 80 inches or more and thicknesses of 130mm or more.
• Establishment of Full Process Automation System: We have established an automation system for the entire process, from pipe bending to cutting, welding, and inspection, achieving increased productivity and cost reduction. By introducing robotic welding technology, we are addressing the decreasing workforce and entering the ranks of global leading companies.
• Application in Various Industrial Fields and International Trust: We supply high-quality piping and bending products to various domestic and international plant sectors, including nuclear power, thermal power, marine, and gas lines, contributing to strengthening nuclear power export competitiveness, such as the export to the UAE Barakah Nuclear Power Plant. We have obtained international certifications such as ISO14001 and OSHAS18001, establishing quality and safety management systems.

Recruitment Information

• Main Hiring Positions: The main positions recruited are bending management department (on-site) and HR/general affairs full-time employees. There is also a history of recruiting for production/process managers, office administrators, and office assistants.
• Benefits: We provide the four major insurances: National Pension, Health Insurance, Employment Insurance, and Industrial Accident Compensation Insurance, and allow for free dress code.
