Schedule 10 Stainless Steel Unthreaded Pipe • Continuously welded 10-ft. lengthEconomical alternative for lower-pressure applications can be used with butt-weld or 150-lb. socket-weld fittings. 304 stainless steel is a chromium-nickel material that offers very good corrosion resistance. 316 stainless steel has a higher nickel content, as well as molybdenum, for even greater corrosion resistance. Use with stainless steel butt weld fittings for applications with air, water, oil, natural gas, and steam.Conform to ASTM-A-312.
