What are the responsibilities and job description for the Pipefitters - Chill Water/Epoxy - Commercial Construction position at Mako Oilfield Services Llc?
Mako Industries is hiring 10-15 Pipefitters with experience in chill water systems and epoxy application that will be involved in the installation, maintenance, and repair of chilled water piping, potentially using epoxy for pipe lining or coating. The term "PMPS" most likely refers to Pumps (Primary/Secondary Pumps), which are a key component of chilled water distribution schemes.
Key Skills and Experience
A pipefitter in this role would generally possess the following skills:
- Chilled Water Systems Expertise: Experience in installing, testing, and maintaining chilled water and hot water systems, including pumps, chillers, air handling units (AHUs), and fan coil units (FCUs).
- Pumps (PMPS): Knowledge of primary and secondary pump installations, maintenance, alignment, and operation within a chilled water loop. This involves understanding flow rates, pressure loss, and the integration of pumps into the overall system design.
- Epoxy Experience: Experience in applying epoxy coatings or using epoxy putty for pipe repair or "pipe lining" (cured-in-place pipe - CIPP). This process requires careful surface preparation (cleaning, drying, sandblasting) and precise application to seal leaks, prevent corrosion, and extend the lifespan of existing pipes without full replacement.
- Pipefitting Techniques: Proficiency in various pipe joining methods, including welding (GMAW, GTAW, etc.), threading, grooving, gluing, and using couplings and flanges, depending on the pipe material (steel, copper, PVC/CPVC).
- Blueprint Reading & Safety: The ability to read and interpret blueprints, isometric drawings, and P&IDs, while adhering to all safety protocols and local/state building codes, including OSHA regulations.
Typical Job Duties
Specific responsibilities might include:
- Installation: Laying out, assembling, and installing new chilled water piping systems and related components based on design specifications.
- Repair and Maintenance: Isolating damaged pipe sections, draining and cleaning them, and then applying epoxy lining to restore function and prevent future issues.
- Pump Management: Installing, maintaining, and troubleshooting primary and secondary pumps, ensuring proper alignment, vibration control, and efficient operation.
- Quality Assurance: Performing camera inspections before and after epoxy application and pressure testing systems to ensure integrity and compliance with standards.
- Collaboration: Working with project managers and other tradespeople, and possibly training O&M staff on system operations.
