Ladder strip coupon holders are designed to simultaneously monitor corrosion at various levels in a process line. This is a technique employed in large diameter pipelines (8″ O.D. and greater) where corrosion may not be uniform across the diameter of the pipe, or in systems where flow is stratified.
The holder body is a single blade containing holes spaced along its length for mounting the coupons.
Special strip coupons are used with ladder holders.
These coupons have a mounting hole at each end for secure mounting.
Coupons are arranged so that three pairs may be mounted on the holder; one pair at the top, one pair at the center, and one pair at the bottom.
A minimum holder length of 26 cm (10.25″) is required to mount three pairs of coupons.
Mounting procedures for ladder strip coupons are the same as for standard 2-hole strip coupons
