6 MATERIAL FOR BENDS CONTAINING WELDS

6.1 LongitudinaL WeLd Seams

6.1.1 Seam welds in pipe made to an API. ASTM, or CSA specification must meet welding and nondestructive examination (NDE)

requirements of that specification.

6.1.2 Other pipe or cylinders. net manufactured to the above specifications, shall be made by welders, welding operators, and

welding procedures qualiFied under the provisions of Section IX of the ASME Boiler and Pressure Vessel Code (HPVC). Before bending. 100% of each weld seam shall be radiographed In accordance with ASME Section VIII, DIvision 1, para. LJW-S1, and shall meet the

acceptance criteria specified therein.

In place of radiographic examination, welds may be ultrasonically examined in accordance with Appendix 12 of ASME Section VIII.

Division 1.

6.13 The longitudinal weld seam should be located on the neutral axis ( = 0 deg or 180 deg in Figure 1). When this is not possible, the weld seam shall be located not more than 15 deg from the neutral axis. Helically welded pipe is an exception to this weld

location requirement

6.2 Girth WeLds

Bending through a girth weld shall not be allowed unless agreed upon between the purchaser and manufacturer.
