A strong, flexible cast iron alloy used in pipes, fittings, and valves on oil and gas and construction sites. It resists cracking under pressure, making it common in water, gas, and slurry line installations. Subcontractors should confirm material specs before procurement, as ductile iron has specific handling and joining requirements.

Utility Boring
IndustryA trenchless drilling method used to install underground conduits, pipelines, or cables beneath roads, rivers, or structures. Subcontractors are often hired for utility boring to minimise surface disruption on job sites. Scopes typically include equipment mobilisation, bore path planning, and spoil disposal.
Natural Hydrogen
IndustryHydrogen gas that occurs naturally underground, now being explored as a clean energy source. Subcontractors may encounter exploration and drilling projects targeting natural hydrogen deposits. It is an emerging sector creating new field service opportunities across Canada.
Hydrotesting
IndustryA pressure test using water to verify the integrity of pipelines, vessels, or equipment before commissioning. Subcontractors are often scoped separately for hydrotest labour, equipment, and water disposal. Confirm whether these costs are included in your contract or billed as extras.
OSHA
IndustryOccupational Safety and Health Administration. The US federal agency responsible for workplace safety regulations. Compliance with OSHA standards is required for contractors working in the United States.
Tank Battery
IndustryA group of storage tanks at a well site that collect and separate oil, gas, and water from production. Subcontractors are frequently mobilised here for gauging, maintenance, and fluid handling work. It is a common recurring service location on producing leases.
Grid-Tie
IndustryA system that connects on-site power generation to the utility grid. Subcontractors working on grid-tie installations must coordinate with utility companies and meet strict interconnection standards. Common on solar and wind projects in remote industrial or construction settings.
