Pipe Mill & Coatings Inspection

With the success of the shale revolution, the midstream market is booming and demand for pipelines is at an all-time high. As new line pipe is rolled and/or fabricated, inspection is an important consideration. Hawk’s Pipe & Coatings division focuses exclusively on ensuring that all pipe produced meets client requirements and conforms to accepted standards (usually API 5L).

“People don’t do what you expect, but what you inspect.”

Typically, most line pipe is coated after production and Hawk provides highly qualified Coatings Inspectors to monitor these processes.

Normal or typical coatings inspection duties include:

  • Visual inspection prior to coating

  • Atmospheric condition monitoring

  • Verification of type of coatings to be used

  • Surface preparation

  • Wet and dry film thickness checks

  • Monitor curing operations

  • Visual inspection (post-coating)

  • Adherence checks

  • Holiday testing

  • Monitor and inspect for handling damage

  • Witness and document all repairs

  • Daily reporting to client and coating progress monitoring


Lastly, Hawk often provides inspection support during loadout and shipping processes. This is critical as transportation related damages are often the leading cause of problems in the field. Hawk personnel can be deployed as pipe is shipped via truck or rail from the mill or coatings facility and also at remote receiving sites along the pipeline right-of-way (ROW).

Hawk’s Loadout and Logistics personnel will monitor the following:

  • Monitor storage and loadout conditions

  • Review shipping documentation

  • Maintain Traceability

  • Ensure appropriate dunnage is used

  • Photograph incoming/outgoing loads as appropriate

  • Document shipping damages

  • Interface with client personnel to resolve issues
