## Task statements
|
|
|
|
- **[Core]** Examine boilers, pressure vessels, tanks, or vats to locate defects, such as leaks, weak spots, or defective sections, so that they can be repaired.
|
|
- **[Core]** Bolt or arc weld pressure vessel structures and parts together, using wrenches or welding equipment.
|
|
- **[Core]** Inspect assembled vessels or individual components, such as tubes, fittings, valves, controls, or auxiliary mechanisms, to locate any defects.
|
|
- **[Core]** Repair or replace defective pressure vessel parts, such as safety valves or regulators, using torches, jacks, caulking hammers, power saws, threading dies, welding equipment, or metalworking machinery.
|
|
- **[Core]** Attach rigging and signal crane or hoist operators to lift heavy frame and plate sections or other parts into place.
|
|
- **[Core]** Bell, bead with power hammers, or weld pressure vessel tube ends to ensure leakproof joints.
|
|
- **[Core]** Lay out plate, sheet steel, or other heavy metal and locate and mark bending and cutting lines, using protractors, compasses, and drawing instruments or templates.
|
|
- **[Core]** Install manholes, handholes, taps, tubes, valves, gauges, or feedwater connections in drums of water tube boilers, using hand tools.
|
|
- **[Core]** Study blueprints to determine locations, relationships, or dimensions of parts.
|
|
- **[Core]** Straighten or reshape bent pressure vessel plates or structure parts, using hammers, jacks, or torches.
|
|
- **[Core]** Shape seams, joints, or irregular edges of pressure vessel sections or structural parts to attain specified fit of parts, using cutting torches, hammers, files, or metalworking machines.
|
|
- **[Core]** Position, align, and secure structural parts or related assemblies to boiler frames, tanks, or vats of pressure vessels, following blueprints.
|
|
- **[Core]** Locate and mark reference points for columns or plates on boiler foundations, following blueprints and using straightedges, squares, transits, or measuring instruments.
|
|
- **[Core]** Shape or fabricate parts, such as stacks, uptakes, or chutes, to adapt pressure vessels, heat exchangers, or piping to premises, using heavy-metalworking machines such as brakes, rolls, or drill presses.
|
|
- **[Core]** Clean pressure vessel equipment, using scrapers, wire brushes, and cleaning solvents.
|
|
- **[Core]** Conduct pressure tests on vessels, such as boilers.
|
|
- **[Supplemental]** Install refractory bricks or other heat-resistant materials in fireboxes of pressure vessels.
|
|
- **[Supplemental]** Assemble large vessels in an on-site fabrication shop prior to installation to ensure proper fit.
