Sumitomo Metals is at the forefront of the Japanese seamless pipe industry. In 1998, despite a sluggish oil industry activity, as well as a trend of strategic restructures among tubular manufacturers, Sumitomo Metals concentrated all of its proprietary technology in the construction of a state-of-the-art medium size seamless pipe making plant This plant besides being extensively automated, inaugurated numerous innovative technologies developed in house represented by the High-Toe-Angle Piercer, dinamically adjustable sizer, inline heat treatment and so on.

In 1999, the new steel making plant, which is another embodiment of SMI technology, was constructed next to the medium size pipe making plant and directly connected to it, to become the world's first in line pipe making process.

Thanks to these best-in-class facilities, Wakayama Steel Works boasted quality and productivity, and consolidated Sumitomo Metals' position as the leading pipe technology company.

Besides Wakayama Steel Works where Carbon steel, low alloy steel, and martensitic stainless steel grades are produced, Sumitomo Metals operates another seamless pipe manufacturing plant, Amagasaki Tube Works which has been fulfilling the majority of CRA OCTG worldwide demand of such as Duplex stainless steel and Nickel based alloy.  

Sumitomo Metals has historically been the leading pioneer in developing high performances OCTG and a number of Major Oil and Gas companies have selected Sumitomo Metals as a long term partner.

The Company's large diameter welded pipes produced in Kashima Steel Works have been deployed all over the world in oil and natural gas pipelines.

In the domestic boiler tube market, Sumitomo Metals fulfills approximately 80% of the demand for the main tubes of thermal power generation plants and for boiler tubes used in large-scale industrial projects. Our electric-resistance welded pipe sector has been integrated into Sumitomo Pipe&Tube Co., Ltd. operations in 1999.

Sumitomo Metals Pipe and Tube company together with Sumitomo group sister companies have built a world-wide reputation of quality and innovation as a manufacturer of critical application tubular used across a number of industries.
