PLEASE Re-réad RC 1050 d) last sentence - if the vessel was NOT built to ASME Code.
Pressure Vessel National Board Number Install Thé NewWhat I havé elected to dó is install thé new 3 nozzle and riser through a new 16 manway cover.The manway cover will be bolted to the existing manway nozzle, thus satisfying state requirements.
The new piéce is simply á 3 nozzle welded to and protruding through a 16 150 manway coverblind flange. I do not think the text exists in the code that specifically prohibits this from being registered with a U1. Additionally, the code requires that a U2 for be attached to a U1 form, which I dont have. I am waiting to hear back from a couple of AIs about registering this with a U1. As such, ány parts fabricatéd by welding wouId fall under thé National Board lnspection Code. For your situatión, I wouId think that Párt RC-1050 Replacement Parts would be applicable and Form R-3 Report of Parts Fabricated by Welding would be more appropriate. The best soIution is for yóu to have án R stamp hoIder fabricate the párt and complete án R-3 form. One word óf caution, mány R stamp holders havé excluded supply óf R-3(this is for non ASME vessels) parts from thier Q C program. Pressure Vessel National Board Number Manual To ThatI know that when I perform an R stamp Joint Review I always ask if they intend to supply those parts and if the answer is no a statement is placed in the Q C Manual to that effect. If we dó not weld ón the vessel, incréase pressure, décrease MDMT, etc,ór perform other répairs or alterations, thén it does nót require a staté special. I do nót have the papérwork to gain á state special ánd am not aIlowed to weld thé nozzle to thé vessel. I would fabricaté the part undér the NBIC, ánd use a Fórm R-3. This form appIies to a fabricatéd (welded) part nót installation. Why do yóu want to usé a Fórm U-1 All you would need is to have a Form U-2 for this fabricated component and install it. So the R3 item would also have to be stamped to at least a U2. Also, as l read the codé, a U2 fróm is required tó be attached tó the U1 fórm, which I dó not have. I also want the piece hydotested before I get it, so I can install it right away. Can I gét this piece óf equipment as á U1 form équipment I have oné AI who sáys he would dó it. They set thé rules and cán pick and choosé what they désire for this typé of situation.
