Using bending machines to form marine pipe

URN: SEMME2012
Business Sectors (Suites): Marine Engineering Suite 2
Developed by: Enginuity
Approved on: 2018

Overview

This standard identifies the competences you need to bend and form pipe for marine applications, using bending machines, in accordance with approved procedures. The type of pipe to be bent and formed will include ferrous, non-ferrous and non-metallic pipe. In producing pipe bends and forms, you will be expected to use a range of tools, forming equipment and techniques, appropriate to the type of material and operations being performed.

Activities include cutting the pipes to the required lengths using saws or pipe/cutting machines, bending pipes using hydraulic bending machines or power operated equipment such as presses, the use of heating techniques to aid the bending process and the use of templates or set wires to check bend profiles. The pipework produced will have features that include angular bends, offsets, bridge sets and expansion loops.

Your responsibilities will require you to comply with organisational policy and procedures for the marine pipe bending and forming activities undertaken and to report any problems with the equipment, materials or pipe bending activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work to instructions, either alone or in conjunction with others, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will be sufficient to provide a sound basis for your work and will provide an informed approach to applying marine pipe bending and forming procedures using machines. You will have an understanding of the pipe bending and forming activities used and their application, and will know about the pipe bending and forming equipment and techniques, in adequate depth to provide a sound basis for carrying out the activities to the required specification.

You will understand the safety precautions required when carrying out the marine pipe bending activities, and when using the associated tools and equipment. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.


Performance criteria

You must be able to:

  1. work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
  2. confirm that the equipment is set up correctly and is ready for use
  3. operate the machine controls safely and correctly in line with operational procedures
  4. cut and prepare the pipes to the required specification using appropriate methods and techniques
  5. bend and form the pipes to the required specification using appropriate methods and techniques

  6. produce formed pipes to the required specification

  7. carry out quality sampling checks at suitable intervals
  8. deal promptly and effectively with problems within your control and report those that cannot be solved
  9. shut down the equipment to a safe condition on conclusion of the machining activities

Knowledge and Understanding

You need to know and understand:

  1. the specific safety precautions to be taken when working with marine pipe bending and cutting equipment
  2. the specific personal protective equipment (PPE) to be worn when carrying out the marine pipe bending activities
  3. the hazards associated with carrying out the marine pipe bending activities (such as handling long pipe lengths, using power operated bending equipment, using heating equipment) and how they can be minimised
  4. how to obtain and interpret information from job instructions, drawings and specifications, in relation to work undertaken
  5. principles and methods of marking out pipework, and the type of equipment used (such as direct marking, use of templates, use of set wires)
  6. how to prepare the pipes in readiness for the marking out activities (such as visually checking for defects, cleaning the materials, removing burrs and sharp edges)
  7. methods of holding and supporting pipework during the marking out activities, and the equipment that can be used
  8. the allowances to be made in the marking out, for bending or the assembly of the various fittings that will be used
  9. the characteristics of the various materials that are to be used with regard to the bending operations and why some materials may require the addition of heat or hot air to aid the bending process
  10. the methods used to bend and form the pipe (including the use of hand bending machines, hydraulic bending equipment, power operated equipment and heating methods)
  11. how to produce the various bends required (such as angled bends, dog-leg sets, bridge sets and expansion loops)
  12. the tools and equipment used in the cutting, bending and forming process
  13. why tool/equipment control is critical and what to do if a tool or piece of equipment is unaccounted for on completion of the activities
  14. recognition of contaminants and the problems they can create and the effects and likely symptoms of contamination in the pipe system
  15. the procedure for the safe disposal of waste materials
  16. the recording documentation to be completed for the marine pipe bending and forming activities undertaken and where appropriate, marking and identifying specific pieces of work in relation to the documentation
  17. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
