ASTM B705
ASTM B705
(OP)
ASTM B705 clearly states that the pipes shall be welded with no addition of filler metal yet a number of European manufacturers all happily use filler metal and then certify their pipe as meeting ASTM B705. Am I missing something in B705; or, can anything the manufacturer likes be printed on materials certificates?

RE: ASTM B705
Its a good thing to get to know your mills and fabricators, from their raw material suppliers, into their production methods, testing and quality control practices, and do that on a first hand basis. There is no substitute for visiting the shops as part of the qualification process and to have inspectors watching the inspectors during production, testing and delivery. After all, there are many materials on the market that, even if produced to spec on the day they left the shop, wouldn't meet the spec today. It seems that not only fruits and vegetables are perishable. Inspection and Q/A/C is a full time job, almost as much as is making a quick buck.
