ASTM A1117 is the standard practice for application of thermal spray aluminum (TSA) coating to carbon steel pipe. It provides a technical basis for applying an aluminum coating to pipe surfaces, helping support corrosion protection and more consistent coating work. For buyers, engineers, and quality teams, this ASTM standard is useful when defining expectations for TSA application methods, process control, and compliance documentation in pipe coating projects.

Purpose of ASTM A1117

The purpose of ASTM A1117 is to guide the application of thermal spray aluminum coating on carbon steel pipe in a repeatable and controlled way. As a practice standard, it is generally used to support consistent coating application rather than to describe every possible pipe coating system. The document helps align fabrication, coating, inspection, and procurement teams around a common technical reference for TSA-coated pipe.

Common use cases of ASTM A1117

ASTM A1117 is commonly referenced when carbon steel pipe needs thermal spray aluminum protection for service environments where coating performance matters. It may be used in coating shop workflows, project specifications, and acceptance planning for pipe materials that require TSA application. The standard is also relevant for contractors, inspectors, and purchasers who need a shared basis for specifying how the aluminum coating should be applied to pipe surfaces.

Why ASTM A1117 matters

This standard matters because coating application quality can affect long-term performance, consistency, and project acceptance. ASTM A1117 gives stakeholders a common technical document to support coating specification, quality control, and procurement decisions for carbon steel pipe. Using a recognized ASTM standard can reduce ambiguity, improve communication between suppliers and end users, and help support compliance reviews and product evaluation for TSA-coated pipe systems.
