ASME IX Welding Requirements Part 2 Welding

Unfortunately ASME Section VIII Division 1 has not made the rules of QW-193 Tube to tubesheet tests mandatory, so typically the rules of QW-202.2 and QW-202.4 apply (see QW-202.6).

Such Procedure For Tube to Tube-sheet Joint Expansion - Insert the tubes in the tube sheet from one end. Set the tube projection to the max. 3mm in one end, as required in the drawing. Carry out expansion in one end. Check the projection on the other end. If the tube projection is more than 4mm then the tube ends are to be trimmed to maintain the projection at 4mm. Carry out expansion on the other end.

Thickness range for welder qualification and procedure tube to tubesheet weld procedure qualification asme

It means that a particular welding procedure specification (WPS) gets qualified for a particular thickness range and if we have to weld beyond that thickness range then we need a new WPS and procedure qualification. The thickness range for which a Welding procedure specification (WPS) gets qualified is given in ASME BPVC section IX Table QW 451.1. Tube-To-Tubesheet Welding Development Programs For Abstract. Special welding techniques for joining Inconel weld overlays on type 316 stainless steel tubesheets and channels are described. The program for the development of the required welding procadures are divided into three specific progranns overlaying Inconel filler Metal 82 on type 316 stainless steel, welding type 316 stainless steel tubes to a type 316 stainless steel tubesheet, and tube to tubesheet weld procedure qualification asme Tube-to-Tubesheet Connection Process EngineeringSeal welding is defined as a very small bead of weld around the tubes where no credit can be taken for strength of that weld for calculation of tube-to-tubesheet joint load.

Tube-to-Tubesheet Weld QualificationHello everybody, We are planning to conduct Procedure qualification for welding tube-to-tubesheet partial penetration strength weld of HEX. ASME IX QW-193 is not specified per original code. So, we have chosen to go for qualification by Groove Weld as per ASME IX QW-202.6(a). The tube thickness is 2.11mm. The thickness of tubesheet is 60mm. Welded Heat Exchanger Tube or Tubesheet Joints 4. Qualification 4.1 Weld Procedure Qualification.

Procedure qualification. For welding procedure qualification, ASME IX does not regard pipe diameter as an essential variable and, thus, procedure qualification testing using a particular pipe diameter will qualify pipe of any other diameter. Also, QW 211 states that qualification in plate also qualifies for pipe welding and vice versa.

Your tube-to-tubesheet weld is a GROOVE weld, not a fillet weld. Consequently you must qualify the tube-to-tubesheet weld with an impact tested groove weld test coupon, according to QW-202.4 this shall be at least 6 mm thick on at least one side. As I read UHA-51(f) you must qualify your welding material and your welding procedure with impacts. tube to tubesheet weld procedure quatube to tubesheet joint strength welded tubes to tubesheet tubesheet design tube to tubesheet weld procedure quatube to tubesheet joint strength welded tubes to tubesheet tubesheet design FORM TEXP-2 SUGGESTED FORMAT FOR TUBE-TO Procedure Qualification Record number Date TEPS no.
