Since its establishment in 1978,
SUNG IL SIM has accumulated decades of expertise in pipe manufacturing. Based on this experience,
the company pioneered the 100% localization and development of high-frequency bending machines in Korea.
We manufacture and supply high-quality factory-processed pipes for various industries,
including nuclear power, coal-fired power, combined-cycle power, ships, and offshore plants.

To ensure the best pipe manufacturing technology and quality, we have established and continuously
operate an internal quality system, which is widely applied in key national industries.

Guided by our core company values of creativity, faith, and sincerity, we provide the best service to meet customer needs.
In the face of the rapidly changing global competitive era, we aim to lead the domestic and international pipe manufacturing industry,
fulfilling our responsibilities to create a prosperous society and contribute to social development.
