Specifications
Some engineers have a tendency to prepare the technical portions of heat exchanger tubing purchase orders that simply invoke a pertinent ASME or ASTM specification for citation of all buyer specified engineering and QA/QC requirements.  This is an unfortunate circumstance, because these national codes were never intended to provide all technical requirement aspects of purchase specifications.

Review of these national standards will show that they only provide minimum engineering requirements and that they contain nearly cursory QA/QC input at best.   Considerable technical requirements and QA/QC methodologies/test frequency expansion is required to produce an acceptable pruchase specification.  Otherwise, the heat exchanger tube fabricator will be permitted to unreasonably cut its costs, much to the detriment of the purchaser.

Corrosion Resolutions reviews and comments on or creates heat exchanger tube performance specifications, i.e. specifications that cite the requirements of the pertinent national standards and also cite additional comprehensively detailed engineering requirements, but do not stipulate the means by which the selected tube fabricator will achieve the desired results.

We custom design detailed performance specifications for virtually any common engineering material to meet client formatting, commercial, and technical requirements. We also address all engineering and QA/QC aspects in our specifications and generally can furnish them on a reasonably quick turn-around basis.

Shop QC
We also perform detailed tube fabrication QC procedure reviews and conduct thorough shop QC inspections.  When we conduct shop inspections, we provide daily verbal reports of findings/corrective actions/proposed immediate client action item recommendations, and furnish detailed written trip reports on a timely basis.

Material Selection & Commercial Studies
Identification of acceptable tube materials is another significant Corrosion Resolutions strength. (see the Materials Selection link of this website).  Additionally, we perform commercial studies, the results of which define the current costs of the various acceptable tube materials and their required fabrication lead times.
