Pipe Cleanliness Standards?
Pipe Cleanliness Standards?
(OP)
Does anyone know of a standard for ordering pipe to a certain cleanliness? We have been receiving "dirty" pipe, but have no specifications which define clean or dirty.
We are also having issues keeping the plastic caps on the ends for storage, so if anyone knows a good alternative I would apreicate some advice.
Thanks,

We will design everything from now on using only S.I. units ... except for the pipe diameter. Unk. British engineer

try plugs instead of caps? go to caplugs.com and call them and ask what to use... they might be able to help

The following is from withdrawn ANSI Standard N45.2.2 "Packaging, Shipping, Receiving, Storage, and Handling of Items for Nuclear Power Plants." It applies to general piping, so it might be useful, even though you probably aren't at a nuclear plant. I highlighted a few words, because I don't know how clean is clean enough -- that will depend on your end application.
Under Shipping, the standard stated:
(1) Items, just before packaging, shall have been inspected for cleanness according to the requirements specified in the purchasing document. Dirt, oil residue, metal chips, or other forms of contamination shall have been removed by approved cleaning methods. Any entrapped water shall have been removed.
(2) All openings into items shall be capped, plugged, and sealed. Weld end preparations shall be protected from corrosion and physical damage.
(3) Items subject to detrimental corrosion, either internal or external, or contamination shall be suitably protected.
Under Reeceiving there was a lot of guidance on what to look for. When it came to "cleanness" the standard had the following:
"Cleanness. Visual inspection to assure that accessible internal and external areas are within the specification requirements for dirt, soil, mill scale, weld splatter, oil, grease, or stains. If inspection for cleanness was performed prior to sealing and shipping, and inspection upon receipt indicates that there has been no penetration of the sealed boundary, then inspection for internal cleanness is optional.
What BigInch posted would likely be a reasonable statement to go in the purchase spec.
