CARBON SEAMLESS & WELDED PIPE

Kobayashi Steel Corporation is a comprehensive manufacturer of seamless, UEO, and ERW steel pipe for pipelines used to transport oil and natural gas from the point of production to points of consumption, with the capacity to offer these products in a wide variety of materials and sizes to suit specific applications. These include a selection of distinctive products such as high-strength line pipe for very large-scale pipelines,

This line pipe, typically of X80 grade, meets the need for thicker-walled steel line pipe to cope with higher transportation pressures and larger diameters. Kobayashi Steel Corporation actively pursues R&D not only on materials but also to develop pipeline design technology and technology relating to the use and assessment of pipelines. We also plan to expand the range of applications of these products.
