(2) Remove the attached O-ring and the back-up ring and store them. (3) Perform tack welding to determine the welding position. (4) Perform arc welding. Using a JISD5016 or D5826 welding rod improves work efficiency. Preheat the surface at 100 to 200 °C before welding. Perform two or three layer fillet welding fully to the corner of the joint, avoiding the catching of slag and undercutting, and maintaining a concave welded shape to disperse stress concentrations.(5) Clean the joint after welding, and after the joint has been cooled to room temperature, attach the O-ring and backup ring correctly. (6) Connect the joint. (7) After all piping work is complete, flush the pipe and conduct a pressure test. Apply low and high pressures in several stages to check oil leakage. After applying the maximum pressure a few times, tighten the cap nut additionally. (8) After starting operation, check oil leakage and the looseness of the cap nut on a regular basis. If any trouble is found, take appropriate measures immediately.Welded stud elbowSLW-1EUW-1/2EUW-3/4EUW-1FEP-127.2R3/4—6517—1413735P2434R180171815846P30P20● An improper work procedure may cause a serious accident. ■SLW■ELWModel code structureWelded joint SUW:Welded stud unionSLW:Welded stud elbowEUW:Welded equal unionELW:Welded equal elbowWelded equal unionELW-1/2ELW-3/470 MPaFEP-1/2FEP-3/470 MPaFEP-1/2FEP-3/4FEP-12227.2—5565—411485—P243450545880351180501890P30Compatible pipe sizeWelded equal elbowELW-1FEP-12227.2—706517—14112—P24346554158580171110018128P20P301/2:FEP-1/23/4:FEP-3/41:FEP-1JointsWelded JointsModelSUW-1/2SUW-3/4SUW-1Maximum operating pressureCompatible pipeϕ P22R1/2AThread sizeWidth across flats54Width across flats351110530P20ϕ FGOverall lengthHWidth across flatsO-ring*Joints for pipes with a nominal pipe diameter of 1-1/4 are also available.
