<p>A corrosion coupon anchoring system (10) for positively positioning at least one corrosion monitoring coupon (20,22) in the production flowpath downhole in a producing well, wherein the preferably cylindrical coupons (20,22) are held firmly within a cylindrical housing (12) suspended out of contact with any other metallic surface. An adaptor (14) threadingly engages the cylindrical housing (12) with a conventional locking mandrel (11) that is locked in place to a nipple (13) positioned in the tubing string. The minimum internal dimension (D2) of the coupon holding section is not less than the minimum internal dimension (D1) of the locking mandrel so as to minimize flow restriction introduced by the anchoring system.</p> |
