Hydraulic Plumber Course

Lesson 1 • Hydraulic System Components Overview

Surveys pumps, actuators, valves, reservoirs, and conductors as the building blocks of hydraulic plumbing systems. Connects component function to overall system behaviour.

Lesson 2 • Core Fluid Mechanics Principles

Introduces pressure, flow rate, velocity, and Pascal's Law as the physical basis of hydraulic plumbing. Establishes the theoretical framework used throughout the course.

Lesson 3 • Regulatory and Safety Framework

Outlines occupational safety standards, pressure vessel regulations, and environmental compliance relevant to hydraulic plumbing. Compliance knowledge is required before any hands-on work.

Lesson 1 • Fluid Contamination and Filtration

Identifies contamination sources, particle count standards, and filtration strategies to maintain fluid cleanliness. Contamination control is the leading factor in hydraulic system reliability.

Lesson 2 • Pipe, Tube, and Hose Materials

Compares steel, stainless steel, copper, and thermoplastic conductors for pressure rating, corrosion resistance, and application suitability. Material choice determines long-term system integrity.

Lesson 3 • Types and Properties of Hydraulic Fluids

Examines mineral oils, synthetic fluids, and water-based fluids, including viscosity, flash point, and compatibility. Fluid selection directly affects system efficiency and component life.

Lesson 1 • Power and Hydraulic Pressing Tools

Introduces electric pipe threaders, hydraulic press-fit tools, and crimping machines for high-pressure connections. Power tools increase speed and consistency in production environments.

Lesson 2 • Tool Safety and Maintenance

Establishes inspection routines, storage protocols, and safe operating procedures for all hydraulic plumbing tools. Proper tool care reduces workplace injuries and equipment downtime.

Lesson 3 • Measurement and Testing Instruments

Trains students on pressure gauges, flow meters, thermometers, and ultrasonic leak detectors used during installation and commissioning. Accurate measurement is essential for system verification.

Lesson 1 • Welded and Brazed Joints

Covers socket-weld, butt-weld, and silver-braze techniques for permanent high-pressure hydraulic connections. Welded joints are required in high-cycle and high-pressure applications.

Lesson 2 • Hose Assembly and Routing

Addresses hose end selection, crimping, bend radius limits, and routing best practices for flexible hydraulic lines. Correct hose routing prevents premature failure and abrasion damage.

Lesson 3 • Threaded Pipe Connections

Covers NPT, BSP, and metric thread standards, thread-cutting procedures, and sealant application. Threaded joints are the most common connection type in hydraulic plumbing.

Lesson 4 • Compression and Flare Fittings

Demonstrates single-ferrule, double-ferrule, and 37-degree flare fitting assembly for tubing systems. These fittings are preferred where disassembly and reassembly are required.

Lesson 1 • Pipe Sizing and Pressure Drop Calculations

Applies Darcy-Weisbach and equivalent-length methods to size pipes and predict pressure losses. Correct sizing ensures adequate flow and avoids energy waste.

Lesson 2 • Pump and Actuator Sizing

Guides students through flow demand analysis, pump curve interpretation, and actuator force calculations. Proper sizing prevents undersized or oversized equipment.

Lesson 3 • Valve Selection and Placement

Covers directional, pressure-relief, flow-control, and check valve selection criteria and optimal placement in circuit design. Valve placement determines system controllability and safety.

Lesson 4 • System Layout and Pipe Routing Plans

Translates schematic designs into physical pipe routing drawings, including support spacing and clearance requirements. Layout plans guide installation crews and reduce field errors.

Lesson 1 • Component Installation Procedures

Details mounting, alignment, and connection procedures for pumps, valves, actuators, and reservoirs. Correct installation procedures protect components and ensure warranty compliance.

Lesson 2 • Pipe Support and Anchoring Systems

Explains clamp types, hanger rod sizing, anchor design, and vibration isolation for hydraulic pipe runs. Adequate support prevents fatigue failures and maintains alignment.

Lesson 3 • Pipe Fabrication and Prefabrication

Demonstrates cutting, bending, threading, and prefabricating pipe spools off-site for efficient field installation. Prefabrication improves quality control and reduces on-site labour.

Lesson 4 • Flushing, Filling, and Pressure Testing

Covers system flushing procedures, fluid filling protocols, and hydrostatic pressure testing to verify installation integrity. These steps are mandatory before system commissioning.

Lesson 1 • Pre-Commissioning Checks

Establishes a systematic checklist for verifying fluid levels, valve positions, electrical interlocks, and safety device settings before first start-up. Prevents costly start-up failures.

Lesson 2 • Operator Handover and Training

Covers documentation packages, operator instruction, and formal handover procedures at project completion. Proper handover ensures operators can run and maintain the system safely.

Lesson 3 • Performance Verification and Adjustment

Teaches pressure setting, flow balancing, and actuator speed adjustment to match design specifications. Verified performance confirms the system is ready for production use.

Lesson 1 • Maintenance Records and Reliability Analysis

Establishes maintenance log formats, failure mode tracking, and mean-time-between-failure analysis to drive continuous improvement. Data-driven maintenance reduces lifecycle costs.

Lesson 2 • Common Hydraulic Faults and Remedies

Diagnoses and corrects pressure loss, excessive heat, slow actuator response, noise, and external leaks. Each fault is linked to root causes and verified repair procedures.

Lesson 3 • Systematic Fault Diagnosis Methods

Applies symptom-based and cause-and-effect diagnostic frameworks to isolate hydraulic faults efficiently. Structured diagnosis reduces mean time to repair and avoids misdiagnosis.

Lesson 4 • Component Overhaul and Replacement

Covers pump, valve, and cylinder overhaul procedures, including disassembly, inspection, and reassembly to manufacturer tolerances. Overhaul skills reduce replacement costs.
