HOW TO CHANGE NON-SOUR SERVICE MATERIAL TO SOUR SERVICE MATERIAL

HOW TO CHANGE NON-SOUR SERVICE MATERIAL TO SOUR SERVICE MATERIAL

HOW TO CHANGE NON-SOUR SERVICE MATERIAL TO SOUR SERVICE MATERIAL

(OP)
We received piping Fittings (i.e. Flanges,elbow, tee, plug, o-lets etc) without NACE, but those fittings further to be utilize for source service line. Our client not agree to accept those fittings.
Is there any possibility to change the fitting to satisfy NACE requirements.

Kindly advise us...

RE: HOW TO CHANGE NON-SOUR SERVICE MATERIAL TO SOUR SERVICE MATERIAL

Assuming that "without NACE" equates to: 'we have received purchased items for which the accompanying inspection documents do not explicitly state compliance with NACE MR0175," then it will be down to you to examine both the information contained in the inspection documents and NACE MR0175 and justify to the client how the received material is actually in compliance.

RE: HOW TO CHANGE NON-SOUR SERVICE MATERIAL TO SOUR SERVICE MATERIAL

IMO, the simplest way is to purchase the new material with NACE compliance, and save the existing Non-NACE piping fitting for future work. Make sure that it isn't your error to purchase the wrong material for the NACE service. And, I don't think it worth to send back the old material to the vendor for exchanging the NACE material.

SJones, If we do corrosion coating to meet NACE requirement and contact Hardness test to justify it comply NACE MR0175 requirement, then client will accept.

RE: HOW TO CHANGE NON-SOUR SERVICE MATERIAL TO SOUR SERVICE MATERIAL

If you miss communicated the correct data, either return the goods and order the correct items, your expense if your mistake, suppliers cost if their mistake or whoever specified the wrong fittings if it's their fault.
Seems pretty straight to me.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

RE: HOW TO CHANGE NON-SOUR SERVICE MATERIAL TO SOUR SERVICE MATERIAL

"Corrosion coating," taken to mean painting or lining, is of zero benefit for compliance with NACE MR0175. If the supply condition of the (carbon steel) items, e.g. free from strengthening cold work, heat treatment, complies with the requirements of NACE MR0175 and the only information missing is hardness values, then, by agreement with the end user, it should be possible to conduct hardness testing to satisfy the standard. Of course, the sampling frequency and hardness test locations will also have to be agreed.

Surezhg,
It may be a weird question. Which part of the world do you work? If you are in thee European or Middle East block, usually the pipe and fittings comes Nace compliant as default. I am sure you have given the MTRs a thorough review.

Not if you don't specifically order it, it doesn't

RE: HOW TO CHANGE NON-SOUR SERVICE MATERIAL TO SOUR SERVICE MATERIAL

It is a difficult proposition to make the client accept the piping material. However, you may give it a try by agreeing to carry out HIC tests on a few samples (the number has to be mutually agreed by the client and yourself).
