FEMCO Steel
Engineering the Future of Steel Pipe

FEMCO has operated its own pipe mill since 1963 and brings more than 60 years of manufacturing experience. Our products are certified by the American Petroleum Institute (API), and strict quality control and continuous innovation keep every pipe in line with industrial and public-works standards. From the 60-inch spiral-welded pipe used in harbor construction to subsea projects, oil and gas, petrochemicals, building structures, HVAC and pressure vessels, we keep moving the pipe industry forward.

ABOUT

About Our Steel Business

FEMCO is a comprehensive steel manufacturer founded in Chiayi, Taiwan.
Since opening its pipe mill in 1963, the company has kept refining its technology and equipment, expanding from small high-frequency welded pipes to 26-inch line pipe and the 60-inch spiral-welded pipe used in harbor works.

Backed by deep industry experience and in-house engineering, we hold API, CNS and other certifications and have long supplied pipe for petrochemical, building, transportation and public-works projects at home and abroad. We also design and build our own pipe-making equipment for domestic and overseas markets, delivering reliable pipe products and complete solutions through innovation, expert manufacturing and rigorous quality.

  • 1976 First company in Taiwan licensed to use the API monogram
  • 2007 Obtained API 5L PSL2, qualified for both PSL1 and PSL2
  • Full product line From ERW and SAW pipe to U-rib stiffeners and pipe mills
  • Designed in-house Pipe-making equipment supplied to manufacturers worldwide
Driving manufacturing with innovation and building the future with quality, we keep advancing our technology to create lasting value for industry and infrastructure.
Steel structures, bridges and public works are where FEMCO pipe performs best.
