Hi!

As of the 99 Addenda there is no minimum qualified thickness for weldor qualification.  The minimum thickness will be that of the applicable PQR.    Remember diameter rules of QW-452.3 still apply.   John A.

No I don't think so Because as per QW 193.1 the mock up assembly shall essentially duplicate tube hole  configuration & Tube to Tube sheet joint design.A s you are changing the projection means you are changing the strength of weld required as per design calculation.

Failed means what is the reason?location and type of failure? Tension value is less?

Good day gentlemen   I recently did an in-service statutory inspection on air start bottles (receivers ) on board a Russian fishing vessel. These vessels were manufactured during 1989-1990 in Russia. My question is, what would the Russian pressure vessel code of manufacture have been? The markings on the vessel “neck” flange is in the Russian language and makes no sense. Please share your thoughts.   Best regards.     Riaan Stoltz RITC Inspection 083 6405909 021 556 4884
