A vast multitude of bureaucratic fluff bearing titles of the form ISO-90xx.

A1) Ensure that the organisation says what it is going to do, makes sure it does it, and says that it has done so.

A2) In the first instance, create documents that say how A1 above is going to be achieved.

You could create a kind of master spreadsheet for all the piping systems involved in any given project. For each piping run of the same diameter, give it a name. Specify the diameter, pressure range, temperature range, pipe material, wall thickness or schedule, insulation if any, type of fittings (threaded, butt-weld, socket-weld, compression, etc.), applicable regulatory code(s), paint color, etc. List any tests required (impact, hardness, hardenability, bending, etc.) with acceptable and actual values. ... ... ...

Given the nature of the original post, it would appear that the original poster is simply unable to do any part of that.

LynDoor Industries® might be able to help, though it would appear that part of that operation has gone into liquidation.

Re: Piping QA/QC

System Pipe Specifications
With reference to B31.3, new specifications for system pipe have been adopted by the Warranty Department on 1 Apr 04. If the customer's pipe does not meet the following specifications, it may interfere with system operation or move the operating conditions away from those specified on the initial bid. In this case, the Warranty may be considered void and any failure will be the responsibility of the Customer.
1. All pipe shall be made of a long hole, encased by metal or plastic material concentric with the hole.
2. All pipe shall be hollow throughout the entire length.
3. Do not use holes of different length than the pipe.
4. All pipe is to be of the very best quality, perfectly tubular or pipular.
5. All acid proof pipe is to be made of acid proof metal.
6. The I.D. (inside diameter) of all pipe must not exceed the O.D. (outside diameter) or the hole may be on the outside of the pipe.
7. All pipe is to be supplied with nothing in the hole so that water, slurry or other process material can be put inside at a later date.
8. All pipe should be supplied without rust. This shall be applied at the job site by the Contractor, Fitter or Customer. Note: Some Vendors are now able to supply pre-rusted pipe. If available, this product will save a lot of time on the job site.
9. All pipe is to be cleaned free of any covering such as mud, tar, barnacles, or any form of manure before putting up, otherwise it will make lumps under the paint.
10. All pipe over 500ft (153m) in length should have the words "long pipe" clearly painted on each end, so the Contractor will know it is a long pipe.
11. Pipe over 2 miles (3.2km) in length must have the words "long pipe" painted in the middle, so the Contractor will not have to walk the entire length of the pipe to determine if it is a long pipe.
12. All pipe over 6" (152mm) in diameter shall have the words "large pipe" painted on it, so the Fitter will not mistake it for small pipe.
13. All pipe closers are to be open on one end.
14. All pipe fittings shall be made of the same stuff as the pipe.
15. No fittings are to be put on the pipe unless specified. Otherwise straight pipe will be crooked pipe.
16. When ordering 90 degree, 45 degree or other elbows, be sure to specify right hand or left hand or the pipe will end up going the wrong way.
17. Be sure to specify horizontal, vertical, uphill or downhill sloping pipe. If downhill pipe is used for going uphill, the water will flow in the wrong direction.
18. Fittings come bolted, welded, or screwed. Always use screwed. They are the best.
19. All threaded pipe couplings should have either right hand or left hand thread. Do not mix the threads or as the coupling is being screwed on one pipe, it is unscrewed from the other.
20. Flanges must be used on all non-threaded pipe connections.
21. Flanges must have bolt holes external to and separate from the big hole in the middle.
22. Fasteners are required to hold flanges together.
23. If flanges are to be blank or blind, the big hole in the middle must be filled with metal.
24. All metal flanges must be cast or forged of the very best quality iron metal, close grained, free from blow holes, lumps, cavities, pock marks, pin pricks, and warts, otherwise we can't use them.
25. Gaskets shall be used to fill in the space between flanges
26. Gaskets are to be made of metal, rubber, plastic, paper, or some kind of goop. Do not use cow or sheep manure, it cracks when it gets dry.
27. All bolts are to be screwed.
28. All bolts must have a head on one end and a nut on the other.

This response is the Best I have ever read.

"1. All pipe shall be made of a long hole, encased by metal or plastic material concentric with the hole.
2. All pipe shall be hollow throughout the entire length.
3. Do not use holes of different length than the pipe."

"6. The I.D. (inside diameter) of all pipe must not exceed the O.D. (outside diameter) or the hole may be on the outside of the pipe. "

by #6 I cried from laughing so hard and almost peed myself...

completely unexpected !!!

I particularly liked:

8. All pipe should be supplied without rust. This shall be applied at the job site by the Contractor, Fitter or Customer. Note: Some Vendors are now able to supply pre-rusted pipe. If available, this product will save a lot of time on the job site.

That's a LynDoor® knock-off.

Actually, I have had that in my folders for 8 years. I can't even remember where I found it. It might have been here - from Lyn, or I might have found it somewhere else online.

There are too many variables to cover in such a vague statement.

What are the scenarios in which QA/QC are to focus on?

To what standard are you wanting to extend?

Is this fabrication of Piping, Assembly or is this an Oil pipe line?

hi friend .,

almost my questions same as what you have raised as a question.

this project scope is to provide piping construction to the "food and fragrance" industry.

1. Using B31.3 process piping and B31.9 facility piping code, NACE MR01 75, BS EN 10204 CERTIFICATION.

2. we gonna do piping construction in SS and CS.

3. Passivation in ss pipes for the corrosion resistant.

4. Instrument and components installation.

5. welding - field as well as shop .

6. welding inspection borescopic, RT and LPI.

7. service systems are RMW, RMC, CHWS, CHWR, CWS, CWR, N2, PWH, CIP, etc.

i just made some documents as a QA/QC like -Quality Planning , ITP,material tractability record(incoming inspection), welding inspection procedure such as ( RT, Borescope, LPI), Pickling and Passivation procedure, pressure testing procedure(Hydro,pneumatic ), flushing and drying (N2) and checklist.

anything other than this ?

because am new to this piping.

please assist me if anything other than that ......

You left out the CIP cleaning procedure prior to initial service. Fabricators tend to do this a lot, and it should be borderline criminal, based on what I have seen come out of pipes that damage sensitive equipment downstream.

Looks to be a good start !

"food and fragrance" you may want to research the FDA's Quality System Regulation Part 820. as well as touch on 13485, if aspects reach medical. If in the US.

Make sure all DFMEA's are complete and elaborate on them with your own PFMEA. Every aspect for potential failure. design the quality from this.

In your quality planning, verify every aspect of every step is documented and controlled.

It must be thorough, " Overkill " even because of the consumption aspect.

CYA- following preservation procedures after testing of equipment.

This is a very big and varied topic and as far as I can see in your posts on CR4 you haven't mentioned what type of pipe and what the application is, both of which are vital to even attempt to answer this question.

Is this for in house testing of plastic drain pipe you are manufacturing or perhaps site testing of high pressure gas pipelines you are purchasing and supplying between an offshore oil rig and transfer ship?

If you want an answer you will at least need to narrow down the application and what standards you are currently working to (as standards also vary from country to country).

A2) The answer is in the contract award documentation, which is commercially sensitive, available to the original poster, and cannot be seen from here.

See to it every material(pipe, fittins,fixtures) , procedure, methods pass standards set by the tender specification, lay out and bill of quantity. That should be no more and no less.

Then thats it.

Seems like a question similar to TWI's typical exam question.
