A coupon holder is a device used in corrosion monitoring systems to securely and firmly hold corrosion coupons in place within a pipeline or vessel, exposing them to the fluid flow over time. The coupon holder is attached to the end of the solid plug. A left-hand threaded connection ensures that the holder does not loosen from the plug when the plug is being removed from the access fitting. Coupon holders are made from stainless steel and super alloys.
