Suggested Procedure for the Application of Crystal Industrial’s Corrosion Coupons from India
The process is alike for the different kinds of coupons and their befitting holders. Coupon holders are basically intended to be joined to solid plugs, however Crystal Industrial from India offers coupon holders that can be utilized with a hollow plug.
1. The solid plug must be withdrawn from the access fitting utilizing the retriever and service valve as depicted in the operations manual.
2. The solid plug must be extracted from the retriever, taking caution not to touch Crystal Industrial’s coupons on the coupon holder.
3. Assess the coupons and coupon holder for mechanical harm. Take note of the state of the coupon(s) (e.g. heavily covered with dirt, coated with scale, covered with oily/non-oily film, no deposits, and so on).
4. Extract the coupons from the coupon holder, taking caution not to come into contact with the coupons with uncovered hands or instruments.
5. Wrap every coupon individually after noting down the serial number on the coupon and its position in the line (e.g. top of line, base of line, 3 o’clock, and so on).
6. Unscrew the set screw on the coupon holder nut utilizing an allen key. The coupon holder must at that point be withdrawn from the solid plug (note: the coupon holder has left hand threads). The coupon holder must be brushed (when required) and wiped clean.
7. Excavate the primary sealing and O-ring from the solid plug. Analyze and substitute either or both parts if they are harmed, worn or disfigured.
8. The solid plug must be reassembled, fastening the coupon holder nut until it closely holds the primary sealing (note: the primary sealing must not be permitted to spread open).
9. Fix the coupon holder set screw with the allen key.
10. Crystal Industrial’s coupons from India must now be tightly fixed onto the coupon holder. The operator dealing with the coupons must wear a pair of clean gloves.
11. The assembly must be examined to assure that it is tightly fixed with no free parts.
12. The position of the Crystal Industrial’s coupons must be marked on the solid plug utilizing a metal file.
13. The threads and O-ring on the solid plug must be wiped with lubricant.
14. The coupon holder assembly is now prepared to be positioned in the access fitting body. Crystal Industrial’s retriever and service valve must be utilized (in pressurized
systems) to establish the solid plug with the coupon holder connected.
15. Last fixing of the plug in the access fitting must assure that Crystal Industrial’s coupons from India are lined up parallel to the operative stream. (Note: don’t extricate the solid plug to accomplish orientation, as this may influence the connection seal in the access fitting).
