PJ

What PJ does

PJ Inc. is a privately-owned joint venture engineering firm specializing in long-distance slurry pipeline transportation systems. The company delivers end-to-end services across the pipeline lifecycle for mining companies, oil & gas operators, and water utilities, operating an integrated portfolio of six core service modules: Engineering Services, Construction Management, Pipeline Field QA/QC, Commissioning and Start-up, Pipeline Integrity Management, and Tailings Disposal System design, supplemented by Specialized Staffing for tendering, evaluation, and commissioning support.

The firm's underlying technical capability rests on specialized process hydraulics expertise — including slurry hydraulic design and analysis, pipeline route selection, transient analysis, wear prediction, corrosion control, and pipeline integrity management aligned with ISO 9001 and regulatory standards. PJ markets itself as the global leader in slurry pipeline transportation systems, with personnel recognized as founders of the industry and many individuals possessing over 40 years of specialized experience.

PJ generates revenue through professional services engagements delivered on a project-by-project basis, with pricing not publicly disclosed and likely quote-based per scope, complexity, and geography. The company pursues an enterprise B2B go-to-market targeting mining (primary), oil & gas, and water utilities. The firm was formally established as an independent entity in 2015, drawing on personnel from the original PSI and JRI companies that formed a joint venture in 1995; it currently operates from offices in San Francisco (USA, headquarters), Santiago (Chile, regional HQ), Lima (Peru, regional HQ), and Belo Horizonte (Brazil), with personnel experience covering pipeline systems in 13 countries. Customer visibility is limited; Antamina is named as a flagship mining client with multiple pipeline projects.
