It is also intended to apply, where applicable, to the distribution systems of these products. Wright Members Emeritus T. The specimen may be flattened at room temperature. A change from one material thickness group to another 11007 3. Shielding gas andflow rate.
Before welding on a piping system which isbeing or has qpi used for the compression, pumping, transmission, or distribution of crude petroleum, petroleum products, or fuel gases, welders should consider aspects that affect safety, such as operating pressure, flow conditions, and wall thick- ness at the location of the welding.
Figure 4-Nick-Break-Test Specimens-Groove Welds 6 inches millimeters long, and the long edges are to be slightly rounded. For each specimen, at least one face of each cross section is to be ground smooth and etched with a suitable etchant, such as ammonium persulfateor hydrochloric acid, to give clear definition to the structure of the weld.
A change from one welding process or combination of processes to any other welding process or combination of processes. The use of this recommended practice is voluntary, and it is intended to apply to the maintenance gas welding andarc welding of piping usedin the compression,pumping, and transmission of crude petroleum, petroleum products, and fuel gases. APT publications may be used by anyone desiring to do so. Diameter groups might be as follows: Designate whether the flame is neutral, carburizing, or oxidizing; for each size rod or of wire, designate the size of each orifice in the torch tip.

Full Description Please note: Figure 2 shows suggested locations where test specimens should be cut from the test assembly shown in Figure l. Authorization for Repair by Welding Defects may not be repaired without prior company authorization. Figure Maximum Distribution of Gas Pockets: A change from one gas to another or from one mixture to a different mixture. Undercutting adjacent to thefinal bead on the outside of the pipe should not exceed a depth of.
The tensile tests maybe omitted; if they are omitted, the specimens designated for the tests are to be subjected to thenick-break tests. Proper attention should be given to up and to carfit the bon equivalentfactor and chemical composition both the of sleeve and the carrier pipe.
Results of any qualification examinations. Method of exploration of the crack area.
This recommended practice does not preclude using other methods besides welding to install appurtenances or make repairs. The diameter of the cluster exceeds inch The notch shall be cut using a saw or milling cutter.
Change in pipe, fitting, and repair materials. The dimensions should be measured asshown in Figure 6. The cracking process is related to the hydrogen absorbed by the hot weldment. Change in speed of travel. Designate the sizes and of classification number of the filler metal and the minimum number and sequence of the beads.
The specimen may be flattened at room temperathe weld or between the weld and the fusion zone. They can be used after they have been qualified by the user. Additional inspection methods may also be used.
Any equipment which does not meet the requirements of the qualified welding procedure must be repaired or replaced. FB or SB 3. Designatethe composition of the gas and the range of the flow rate.
