The Water Jetting Association (WJA) Approved Tube and Pipe Cleaning Course

Who is the course for?

This course is designed to offer the participant both classroom based theoretical tuition together with practical instruction in the safe and efficient use of high pressure water jetting equipment and accessories for various types of tube and pipe cleaning applications such as clearing blockages, scale and debris.

Are there any prerequisites?

Participants must hold a current valid Safety Awareness Certificate and Photocard issued by the WJA.

What is involved?*

This is a two-part half day course covering surface cleaning and preparation consisting of theoretical classroom based and practical hands on training.  At the end of the theoretical element there will be a question paper with 20 questions with a pass mark of 75%.

Once the course has been successfully completed participants will be issued with a Certificate by the Water Jetting Association (WJA).  The Certificate is recognised by the Health and Safety Executive (HSE) and is City and Guild Accredited (C&G).  This course does not need to be repeated but please note – If your Safety Awareness certificate goes out of date, for any reason, your other certificates immediately become invalid.  A valid Safety Awareness certificate is required to keep all certificates validated.

Example of the Tube and Pipe Cleaning Certificate and Photocard issued by the WJA on successful completion of the course. This certificate only has to be taken once and it remains valid as long as a valid Safety Awareness Certificate is in force.

4. Jetting Equipment – Nozzles and Ancillaries

Review nozzle principles – fixed jet nozzles, rotating nozzles, life and wear characteristics, associated ancillary equipment including automatic, semi-automatic.

5. Jetting Equipment – High Pressure Hose

Hose used in tube and pipe cleaning applications, including flexi and semi-rigid lances; damage and wear possibilities; hose ancillaries. Bore size and flow capabilities, in particular for flexi and semi-rigid lances.

6. Jetting Equipment – Machines

Range of jetting machines used, engine controls and instruments. Pump pressure controls, review dump/dry shut and selector/fail safe types, auto engine speed control systems, pressure safety relief. Water supply/delivery features – filtration requirements, boost feed pumps, built-in anti-freeze provisions.

7. Job Assessment and Planning

Information and assessment – site location, access to and layout of tube bundle/pipeline; base material and nature of contaminants – initial condition and required finished condition; water provision, waste disposal, hazards. Selection of equipment and manning levels – jetting machine/nozzles/accessories, number and duties of operators, single person operation. Determine job method, based on safe system of work.

8. Operational Procedures

Daily checks – manufacturer’s instructions, other items requiring regular checks. Setting-up – permits/authorisations, barriers and warning signs, positioning of machine and equipment, team duties and signals, flushing, leaks check, tube preparation for entry. Nozzle entry and removal, control and monitoring during cleaning – debris, waste containment, standard of finish. Job completion – client inspection, waste removal, equipment decontamination, return site to safe condition.

9. Practical Exercises

Jetting machine and equipment – review features, and demonstrate daily checks, start/run/stop. Job assessment – review and discuss, site location and constraints, accessibility, screening requirements. Tube type and material – nature of contamination, standard of finish required. Water supply, effluent drainage. Hazards and use of PPE. Discussion of options and agree job method. Site preparation – setting up work area. Team talk – review job method, signal, set up team(s). Position jetting machine, layout and check equipment. Demonstrate all procedures to full group. For all teams, instruct each operator in each duty. Trainees carry out exercise, each team following instructions to set up, flush, check for leaks, prep for nozzle entry, proceed with operation. Rotate team members through duties. Review at each rotation and final review. Disconnect equipment and clear site.
