Meeting NACE Requirements for Materials Used in the Manufacture of Fittings

How Parker Instrumentation meets NACE requirements for materials used in the manufacture of fittings, Refinery, Instrumentation Products DivisionSince the NACE (National Association of Corrosion Engineers) MR0175 standard was updated to ISO status in December 2003, there has been an air of confusion on what and how products conform to NACE. Some manufacturers simply buried their heads and try to ignore the standard, some simply decided that they would not pursue NACE product-related business, some only certify to old, out of date versions of the standard, and others simply used the wording of certain clauses within the standard as a way of supplying product from materials that do not actually meet the requirements of NACE MR0175.

Parker has taken NACE compliance very seriously and invested a lot of time to ensure that not only did we understand the consequences of the standard but what we actually put out to our customers in the marketplace was accurate and met the criteria of what the standard is advising the Oil and Gas industry.

Engineers from Instrumentation Products Division Europe attended a conference organized by the authors of the NACE MR0175/ ISO 15156 document and arranged for one of the authors to visit our manufacturing facility at Barnstaple to discuss its implications and how we as a manufacturer of saleable goods should be certifying the materials we use for NACE compliant products.

  1.  If stainless steel is deemed by the end user to be the most appropriate material for the given application, Parker compression fittings may be selected in accordance with NACE MR0175 as per Table A.4.

  2. ‘Refer to general service’ applies in those cases in which the standard does not outline a specific table or set of requirements for the given application.
