Additional Info

Stainless steel slip on plate flanges slip over the end of a stainless pipe. Our 150# stainless steel slip on plate flanges are available in 304 and 316 ASTM stainless steel grades. Slip on plate flanges are welded to the joining pipes and cannot be joined to a fitting directly to the flange. A pipe is needed between the fitting and flange.
