The COSASCO® Ladder Strip Coupon Holder can suspend six strip corrosion coupons (3 pair) from a single access fitting point. The Coupon Holder has a left-hand threaded nut which attaches it to the bottom of the COSASCO® Solid Plug Assembly and also serves as a primary packing retainer. Extending from the nut is a single blade with variously spaced holes for corrosion coupon mounting hardware. All holders are supplied with six sets of mounting hardware. Because of space limitations, a minimum length of 10.25 inches (26.04 cm) is available for three pairs of coupons when used with a 5.25 inch (13.34 cm) Access Fitting Assembly. This minimum length will monitor an 8 inch nominal OD pipeline for pipeline corrosion protection and can also be used with any longer access fitting assembly by increasing the length ordered by the additional length over the standard body (5.25" or 13.34").
