Piping and pipe lines

Steel pipes for piping made by NIPPON STEEL supporting development of urban areas and expansion of industries.

Steel pipes are used for a wide range of applications including line pipes for petroleum and gas and piping for plants, and play major roles in the development of urban areas and expansion of industries.
NIPPON STEEL is manufacturing steel pipes for various kinds of highly reliable piping under integrated management from raw materials to products by excellent technologies and various kinds of advanced, highly efficient pipe manufacturing equipment.

Electric and power plants

Specialty tubes and pipes are extensively used in thermal power plants worldwide, leading to the reduction of greenhouse gas emissions.

It is essential that thermal power plants are efficiently operated with tight control of CO2 emissions. For that purpose, these plants require the tubes and pipes that are durable in the severe condition with high temperature and pressure. NIPPON STEEL specialty tubes and pipes contribute not only to the stable operation of thermal power plants, but also to the prevention of global warming by supplying reliable and quality products manufactured under extremely tight quality control.

Petrochemical and other plants

NIPPON STEEL stainless steel and Ni alloy steel pipes can handle harsh environments

NIPPON STEEL's stainless steel and Ni alloy steel tubes and pipes have outstanding properties in terms of corrosion resistance, heat resistance and low temperature characteristics, and they have long been used as materials to handle harsh environments in energy fields such as petroleum refining and petrochemistry.
Going forward, we will work to develop the original only-one of steel to meet cutting edge needs in increasingly harsh use environments, and advance technological innovation even further.

Construction and facilities
