CAPPING AND SEALING OFF ORIFICES

Clause:

1. The orifices (end connections and other openings) for components covered by thispurchase order shall be capped and sealed prior to shipment in order to maintaincleanliness and provide maximum protection against damage and contaminationduring shipment and storage at NNS. Orifices shall be individually capped andsealed. Standard shipping packaging is not an acceptable alternative for capping andsealing of orifices.2. Preferred materials for devices used to cap or plug openings are: non-galvanizedmetal, high-strength rigid plastic, or rubber. However, these materials are requiredto cover openings on piping components with internal crevices or inaccessible areas(valves, pumps, etc…)3. Wood products (including plywood and composites) may be used on items otherthan piping components with internal crevices or inaccessible areas (valves, pumps,etc…), provided they are weather (moisture) resistant, not susceptible todelaminating, splintering, or premature deterioration. Wood products shall also bedurable/strong enough to withstand normal shipping and warehouse typeenvironments (i.e. storage and handling) without degradation in the ability toprovide adequate protection against damage and maintain cleanliness of theequipment’s internal surfaces and parts.4. Any material used shall not pose a contamination or corrosion hazard. The degreeof cleanliness of sealing device in contact with the component shall be equal to thatof the component on which it is installed.5. Other than devices which are self-securing, such as NP type caps, all other types ofclosures shall be attached with wire, nylon ties or bolts, and sealed with tape.6. For flange mating surface protection, all of the approved flange protective coversmentioned above must be attached to the flange at four or more points evenlyspaced around bolt hole circle and/or flange circumference. If nylon ties are usedfor attachment, their individual tested breaking strength must exceed the weight ofthe flange. If used, sealing tape shall be 3M Performance Plus duct tape 8979N,slate blue in color. Tape may also be applied around the complete circumferenceinstead of the four or more individual locations mentioned above. If a flexible flangeprotector is used then it must be attached with tape. If flanges are not available,seal the orifice with tape of type as noted above.7. For protection of weld preps on flanges, fittings and components, the weld prepsshould be protected with an approved cover that is fixed in place with tape of typeas noted above.8. Small components, for which capping/sealing of each orifice as directed abovecannot be accomplished, or is impractical, may have each orifice sealed with tape asdescribed in the previous paragraphs, or may have the entire component enclosed.Enclosing of small components is acceptable as long as the enclosure providesadequate protection against damage and maintains cleanliness of the component’sinternal surfaces and parts.9. The use of yellow wrapping material and attached yellow protection devices, suchas caps and plugs, is strictly prohibited.10. Failure to comply with the requirements herein shall be cause for rejection.Revision History TableRev Description Revision DateC006 ADDED:1.
