ANSI B16.5 / ASME B16.47 SS Siip on Flange Used in
Utmost care is taken towards the packing of the Blind Flanges so as to ensure that the resultant Products reach in the same condition as desired by our customers from varied industries. We focus on every procedure to assure quality, the package we usually prefer is environmental poly bags, and then in free fumigation wooden cases or plate. Also can accept a customized package of Stainless Steel Flange such as OEM by negotiation. We offer just about everything to meet your 304/316 SS Flanges pack requirements. A Lot of emphases is placed on the packing and packaging. The SS ANSI B16.5 / ASME B16.47 BLFF Flange is packed in wooden corrugated boxes foiled in plastic wraps and bubble wraps. Below are Application Industries where we supply and export.
