In-process Quality Control and Quality Assurance Coatings Inspection: Redundant or Complementary Roles?

Available for download

Everyone wants a quality project; the word quality means different things to different people. Owners have unique perspectives on quality and risk tolerance which often differs across industries. The owner of a trash recycling center looking to paint the walls of his loading dock has a different perspective than the owner of a nuclear power plant, looking at the coating systems applied on the interior of his primary containment walls.

The AMPP Contractor Certification Programs (e.g., AMPP-QP 1) and many project specifications prepared by public agencies and private companies require the painting contractor to control the quality of their work by providing a full time trained/certified quality control (QC) inspector on a coatings project. The role of the quality control inspector is to verify conformance to the governing specification using in-process inspection procedures, visual guides, test kits, and instrumentation, including documentation. Additionally, the facility owner may elect to contract with a third-party coating inspection firm to perform quality assurance (QA) inspection on the same coatings project (or assign a member of their staff to assure quality). The QA inspector often conducts the same inspections as the QC inspector. This paper and presentation will explore whether the roles of a QC and QA inspector on the same project are redundant or complementary. Examples of how, together, these roles have thwarted potential coating performance issues in the Chemical Processing environment will be cited.

Critical procedures at blasting and coating shops and steel fabricating shops, include surface preparation, application of primer coats, often shop applications include intermediate coat application, as well as occasionally including topcoat application. These phases of the process are absolutely critical to the long-term success of coating/lining projects. If the industry is serious about quality, specifiers must include language in the project specifications to include mandatory independent qualified coating inspection during shop coating applications.

Nowadays, oil and gas fields containing a high concentration of CO2 and H2S at high temperatures are being operated in many areas. Here, internal corrosion control under these conditions has become one of the significant challenges in oil and gas production wells and a major cause of severe corrosion–related material failure in the industry.

Internal corrosion of the pipelines turns out to be a critical threat to the initial stage of production.

A 2002 study estimated the annual cost associated with corrosion of gas pipelines to be around $5 billion. Corrosion of oil and gas pipelines continues to pose a major issue in the oil and gas industry due to the combination of brine produced with the oil and the type of acid gas present which can lead to significant internal corrosion. Oil and gas reservoirs can be separated into two categories, sweet and sour.
