1. Purpose/ Scope
This Standard Operating Procedure provides the steps to tighten bolts for PE piping connections. The procedure shall be followed whenever PE piping connections are bolted up except for hot bolting or for the tightening of leaking joints. This procedure applies to all Origin Energy operations however a more specific procedure i.e. a site or equipment specific procedure may be used in lieu of this procedure. Apply this procedure to assemble flanges at ambient temperature only, as torques will not be accurate if the flange(s) or stud(s) are at abnormal temperatures. This procedure does not apply to flanged joints which are integral to specific equipment items such as heat exchanger end covers where Original Equipment Manufacturer (OEM) recommendations shall be followed.
Observance of this procedure will help ensure that gaskets provide an effective seal for all operating conditions.
2. Responsibilities/Accountabilities

5. Operating Steps
Table 5.1: Operating procedure - step tracking table.
No. Task Step Task Step Notes Step Tracking 1, 2
1. Thoroughly clean all threads and bearing faces.
2. Check threads for damage or excessive roughness.
Reject studs and nuts that show thread damage. Clean up excessive roughness.
3. Check gasket type, specification, size, rating and condition.
Reject gaskets not to specification, damaged gaskets and asbestos gaskets.
4. Check nuts and studs for proper size, material spec and cleanliness.
5. Check flange faces for corrosion, damage, cleanliness and dryness.
Rectify prior to assembly.
6. Lubricate threads of non-coated bolts with a nickel-based lubricant paste or similar.
NOTE: do not contaminate the gasket or flange face with the anti-seize compound.
Following Origin policy no bolt should be used unless lubricant paste or bolt coating is in use.
7. Align flanges without using excessive force. A pry bar is generally required; manipulate the alignment by levering through mating flange bolt holes.
Ensure the flanges are parallel and that the bolt holes line up. Avoid using the bottom holes for leverage because bottom studs will hold the gasket in place.
8. Insert gasket and bolts ensuring full thread engagement.
Insert bottom bolts to help hold the gasket first.
Ensure gasket is not pinched.
Ensure there are a minimum of 2 threads protruding from each nut.
9. Number the bolts in the order they are to be tightened (as per Appendix A).
The bolts are tightened in a “criss-cross” pattern.
Numbers can be written beside the bolt on the flange with a paint pen.

10. Determine the required torque.
Manufacturer or suppliers recommended torques should be applied when known.
or Appendix B.1 - Torque Chart for Flanges with Non-metallic Gaskets
or Appendix B.2 – Torque Chart for Steel Flanges with Non-metallic Gaskets
Please Note B.1 is for gaskets with 3mm thickness
B.2 is for gaskets with 1.5mm thickness
11. Tighten all nuts finger tight.
12. Tighten nuts in order of the numbering used in appendix A to 30% of the final torque value.
Continue the sequence until all nuts have been tightened to 30%.
Check that the gasket is centred in the flanges and bolts positioned with the head to the top.
Throughout the tightening sequence, check the gap around the flange - if it is not consistent, make appropriate adjustments by selective bolt tightening before proceeding.
13. After the nuts have been tightened to 30 % of their final torque value use some form of indication.
If the bolt size is adequate (approx > 5/8 inch) use a paint pen to add a stroke to the end of the stud
Example first stroke:
if the bolt size is too small the mark will smudge (approx <5/8 inch) use form in Appendix B – Torque Record sheet
14. Repeat step 12 to torque all nuts to 60% of the final torque value.
Check that the gasket is centred in the flanges and bolts positioned with the head to the top.
Throughout the tightening sequence, check the gap around the flange - if it is not consistent, make appropriate adjustments by selective bolt tightening before proceeding.

15. After the Nuts have been tightened to 60% of their final torque value use some form of indication.
If the bolt size is adequate (approx > 5/8 inch) use a paint pen to add a stroke to the end of the stud
Example second stroke:
If the bolt size is too small the mark will smudge (approx <5/8 inch) use form in Appendix B – Torque Record sheet
16. Repeat step 12 to torque all nuts to 100% of the final torque value.
If the gasket begins to deform, the 100% torque value is too high. In this case, use the highest non-gasket-deforming torque for the final torque value.
Check that the gasket is centred in the flanges and bolts positioned with the head to the top.
Throughout the tightening sequence, check the gap around the flange - if it is not consistent, make appropriate adjustments by selective bolt tightening before proceeding.
17. After nuts have been tightened to 100% of their final torque value use some form of indication.
If the bolt size is adequate (approx > 5/8 inch) use a paint pen to add a stroke to the end of the stud
Example third and final stroke:
If the bolt size is too small the mark will smudge (approx <5/8 inch) use form in Appendix B – Torque Record sheet
18. Re-torque bolts to the final torque value:
Start at bolt number 1 and proceed clockwise around the flange and double check that each bolt is fully torqued.
19. Re-torque bolts to the final torque value a minimum of 4 hours after completing step 18:
Start at bolt number 1 and proceed clockwise around the flange and double check that each bolt is fully torqued.
If no documentation, either via tagging or torque record sheet.
Then it must be assumed that retorque has not been complete and step 19 must be completed prior to completing step 20

20. When all bolts have been tensioned to the correct torque after minimum of 4 hours, attach an information tag to each flange with the details:
Flange Number
Date
Torque value
Lubricant used
Installer’s name
In some cases this will not be practical due to the time interval between completion of installation and commission. As well as other factors including weather, animals, etc.
Please keep a copy of this information in Appendix B – Torque Record sheet as backup information.
21. Prior to the system being de-isolated a FIC check must be completed post assembly
Operator to check for the appropriate markings on nuts/studs and that the appropriate information is on the tags attached
Form A-1000-50-AQ-008 is to be used for the FIC stage.
Example of completed symbol on stud if paint pen had been used:
If alternatives were used instead of visual markings the form in Appendix B – Torque Record sheet should have been used to store information
If no documentation exist to demonstrate retorque after a minimum of 4 hours then step 19 must be repeated prior to completion of FIC
22. After the System has been de-isolated:
Operations representative to remove tags and store in the Commissioning Pack.
6. Troubleshooting
1. Check that the correct gasket type has been used
2. Check that the lubricant is suitable
If both 1 and 2 are acceptable an alternative bolt coating may have been applied, reducing the friction such that torque values in Appendix C are too high. In this case use the highest non-gasket-deforming torque (check vendor torque requirements) as the final torque.
7. Record Keeping
For critical steps procedural completion sign-off may be required. The supporting documentation that outlines the critical step is to be signed both by the Operations Technician and the relevant Supervisor as having been completed correctly.
The Field Installation Checklist - Flange Bolt Testing (A-1000-50-AQ-008) is required to be completed by the Contractor and checked by the Origin Energy Construction Supervisor for all flanges post assembly and primarily used as a pre-commissioning check list.
