Changzhou Lianyi Special Stainless Steel Pipe Co., Ltd.
Established in 1984, formerly Wujin Experimental Factory of Shanghai Iron and Steel Research Institute, we are a national SRUI Little Giant & high-tech enterprise.

We produce high-temperature alloy tubes, special stainless steel tubes and corrugated hoses for aerospace, rail transit and auto engines. Our large-diameter ultra-thin-walled tubes and capillaries lead the industry.
Guided by integrity and superior quality, we innovate to advance high-end precision pipe manufacturing.
SEAMLESS STAINLESS STEEL TUBE
Stainless steel small-diameter thick walled seamless pipes, small-diameter ultra-thin walled pipes, small-diameter capillary tubes, etc. The inner and outer surfaces of the tube have good roughness, uniform grain size, consistent performance, good corrosion resistance, high precision, high pressure resistance, and high smoothness.
