Core Responsibilities

Primary Functions

Analyze and interpret complex isometric and P&ID blueprints, schematics, and technical drawings to determine a precise layout for piping systems, fittings, and related equipment.
Perform intricate field measurements and lay out the routing of pipe systems, ensuring all angles, slopes, and connections align perfectly with engineering specifications and building codes.
Expertly cut, thread, groove, and bend various types of pipes, including carbon steel, stainless steel, and alloy metals, using manual and powered tools like pipe threaders, benders, and plasma cutters.
Fabricate and pre-assemble complex piping spools and sub-assemblies in a controlled shop environment or on-site, optimizing for efficient and accurate final installation.
Specialize in the intricate assembly of complex pipe junctions, manifolds, and tie-ins, ensuring leak-proof, high-integrity connections at the most critical points in the system.
Perform proficient welding, brazing, and soldering to join pipes and components, or prepare pipe ends by grinding and beveling for certified welders, ensuring joints meet stringent quality and pressure-rating standards.
Install and secure a wide range of valves, fittings, gauges, pumps, and control components, confirming their proper orientation and accessibility for future operation and maintenance.
Conduct hydrostatic and pneumatic pressure tests on newly installed piping systems to identify and rectify any leaks, weaknesses, or blockages, meticulously documenting all test results for project turnover.
Safely rig, hoist, and position heavy pipes, spools, and related equipment into place using cranes, chain falls, and other lifting devices, adhering to all load calculations and safety protocols.
Install and align pipe supports, hangers, and anchors, such as spring hangers and U-bolts, to secure piping and properly manage system vibration and thermal expansion.
Execute precise bolting and torqueing procedures on flanged joints using hydraulic torque wrenches and other tensioning equipment to achieve specified gasket compression and a leak-free seal.
Perform pre-commissioning activities, including flushing, cleaning, and blowing down piping systems to remove debris and prepare them for operational service.
Select the appropriate type and size of pipes, fittings, gaskets, and related materials based on project specifications, and maintain an organized inventory of materials on-site.
Rigorously adhere to all company and site-specific safety policies, including Lockout/Tagout (LOTO), confined space entry, and hot work procedures, and actively participate in daily safety briefings.
Visually inspect and dimensionally check all fabricated and installed components to ensure they meet a high degree of quality and conform to engineering requirements before and after installation.
Perform routine maintenance and troubleshooting on pipefitting tools and equipment to ensure they are in safe and optimal working condition at all times.
Carefully dismantle and remove old or obsolete piping systems, and perform repairs and modifications to existing systems as required by maintenance projects or plant upgrades.
t- Work collaboratively with other trades, such as welders, millwrights, electricians, and insulators, to coordinate work sequences and avoid conflicts on a busy and dynamic job site.
Maintain accurate records of work performed, including 'as-built' drawing markups, test reports, and daily progress logs, to ensure proper project documentation and handover.
Proactively identify and troubleshoot on-site issues, such as interferences, material discrepancies, or drawing errors, and propose effective, timely solutions to foremen or supervisors.
Install and configure expansion joints, loops, and other specialized devices designed to accommodate the thermal expansion and contraction of piping systems under various operating conditions.

Secondary Functions

Assist in training and mentoring apprentice pipefitters, sharing knowledge of techniques, safety protocols, and best practices to develop the next generation of tradespeople.
Participate in Job Hazard Analyses (JHAs) and pre-task planning sessions to proactively identify potential risks and establish effective mitigation strategies.
Contribute to a culture of continuous improvement by suggesting process enhancements that can increase efficiency, improve quality, and bolster safety.
Maintain a clean, organized, and hazard-free work area, ensuring tools, equipment, and materials are stored properly to promote a safe and efficient work environment.
