If you are looking for thick-walled seamless stainless steel pipes that meet Japanese standards and are suitable for high-pressure applications, we offer JIS G3459 SUS304 Seamless Pipes, specifically designed for high-strength structures, pressure piping, and industrial equipment applications.
JIS G3459 SUS304 stainless steel round pipes are made of SUS304 austenitic stainless steel. While ensuring excellent corrosion and oxidation resistance, their thick-walled design significantly enhances pressure resistance and operational safety. Our SUS304 seamless thick-walled pipes are manufactured strictly according to JIS G3459 standards, featuring uniform wall thickness, high dimensional accuracy, high internal and external surface finish (2B/BA), strong load-bearing capacity, and stable structural performance. They are suitable for high-pressure fluid transportation, industrial piping engineering, water supply and drainage systems, and mechanical structural applications.
GNEE offers custom lengths from 3m to 12m, with stock available for fast delivery. In addition, we provide professional cutting, threading, and welding services to meet various industrial customization needs.
