Boilermakers

Assemble large vessels in an on-site fabrication shop prior to installation to ensure proper fit.

Examine boilers, pressure vessels, tanks, or vats to locate defects, such as leaks, weak spots, or defective sections, so that they can be repaired.

Inspect assembled vessels or individual components, such as tubes, fittings, valves, controls, or auxiliary mechanisms, to locate any defects.

Install refractory bricks or other heat-resistant materials in fireboxes of pressure vessels.

Clean pressure vessel equipment, using scrapers, wire brushes, and cleaning solvents.

Install manholes, handholes, taps, tubes, valves, gauges, or feedwater connections in drums of water tube boilers, using hand tools.

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...

Bolt or arc weld pressure vessel structures and parts together, using wrenches or welding equipment.
