New welded line pipeA new welded line pipe features earthquake-resistant performance.Called NK-HIPER, the firm says its new pipe excels in absorption properties for compression and bending deformation, which would result from ground movements because of liquefaction during earthquakes. The new pipe tests at 1.5 times higher resistance to such deformation compared with conventional pipe of the same specification, the firm says.Pipe is made of high-strength, high-toughness steel plate. It complies with JIS, API, and other line pipe specifications.
