Welds. For the building attachment parts (product group 7), the weld thickness required for assembly are given by the program. This ‘minimum weld thickness’ is designed such that the permissible tensions are only exploited to 50% in favor of high safety. A force applied at 6° in the weld was taken as a basis for the design. The weld thicknesses can be changed later if you enter N.
Welds. Pipes shall be manufactured from steel strips or plates continuously welded along the seams and the height of the inner weld reinforcement shall not exceed 1mm. In the case of pipes used with couplings, the external weld reinforcement shall be ground flush with the outer wall of the pipe over a suitable distance of the pipe. Pipes must have a continuous helical seam but for smaller than 300mm diameter, longitudinal and circumferential seams would be acceptable.
Welds. The mass of shop and field fillet welds shall be assumed as follows: Size of Weld (mm) kg per linear metre 6.3 0.984 7.9 1.213 9.5 1.771 12.7 2.690 5.9 3.936 19.0 5.379 22.2 7.314 25.4 9.774 The mass of other welds will be computed on the basis of the theoretical volume from dimensions of the welds, with an addition of 50 mass percent as an allowance for overrun.
Welds. Pipeline joints will be welded by qualified welders following written welding procedures specifying the methods for welding all required pipeline joints. Welding procedures and pipeline welders will be qualified in accordance with API Standard 1104. The procedures will be submitted to the EFSEC and WUTC for approval prior to construction. These procedures will include methods for welding all required pipeline joints. During construction, welder qualification records will be available as required by 49 C.F.R. § 192.227, and will include a Coupon Test Report.
Welds. 100% of the welds shall be inspected radiographically, by a qualified radiographer. Any defects found in welds shall be replaced or repaired. All repaired welds shall be radiographed again to ensure their integrity.
Welds. 100 percent visually examined by Contractor’s Shop Inspector to criteria in ASME BPVC SEC VIII, Division 1. May 2017 C01025C17 Georgetown Wet Weather Treatment Station 15061 - 3 STEEL PIPE
Welds. V-shape weld (1517-T105EE-2G-GA); • Weld repair (1774-T248A). Each sample is further identified by its unique number. The 1618-B359-B1 is a nickel based alloy (Inconel 600) mock-up, that has 4 side-drilled holes (SDH) (d = 2mm) and 2 flat-bottom holes (FBH) (d = 4mm and 8mm). The average grain size of the mock-up is 90 µm. D522-TG is a coarse grained stainless steel, cast autenoferritic mock-up that possess 5 SDH (d = 0.5 mm) and 5 SDH (d = 1mm), that are located close to surface of the sample. 1517-T105EE-2G-GA is a U chamfer, shielded metal manual arc weld with 30 welding passes. It possesses no disorientation in the welding direction and high disorientation of the average grain tilt. 2 SDH (d = 1.5 mm) are located the middle of the weld at different depths. 1774-T248A is a weld cladding repair mock-up, made from Ni based alloy. It has homogeneous microstructure and quasi-vertical grains. Slight grain disorientation at chamfers. The sample has 4 SDH (d = 2 mm), 4 vertical notches and 5 tilted notches. The technical drawings of the selected mock-ups are presented in Annex 4. This methodology was created assuming that the samples listed above will be used for quantification of imaging algorithm performance. Other samples can be used as well, however they should possess parameters close to the ones listed above.
Welds. 28.01.02 Furnish and install copper weld ground rod and clamp in dirt area, buried box, sidewalk or roadway as per DWG H-5019.
Welds. All welds between flat straps shall be smooth, continuous fillet welds ground smooth where necessary, to re-move any burs or sharp edges. Where flared straps meet 1/2" rod, all welds are ground smooth for appearance.
