This quality control plan outlines the inspection and testing process for the manufacturing of spiral submerged arc welded pipes. It defines 6 stages: 1) inspection of steel coil raw materials, 2) inspection of welding materials, 3) inspection during pipe production processes, 4) destructive testing of products, 5) non-destructive testing of products, and 6) final inspection of products. The plan provides details of responsibilities, inspection points, testing frequency, standards, and acceptance criteria to ensure the pipes meet specifications.

Abbreviations
I (Inspection): Manufacturer indicate any inspection point of the process to assure conformance of the given requirements.
W (Witness Point): client’s inspector to be informed 3 day before starting the task and may proceed with past the witness point, if the client's inspector is not available.
R (Review Document): It is surveillance of a document for the purpose of verifying that an activity conforms the established requirements.
H (Hold Point): Client’s Inspector to be informed 3 working day before starting the task and work shall not be done without witness of Client’s Inspector.
SW(Spot witness): Witness is non- mandatory;the Manufacture shall inform employer incpectorthe start of activity date.the imployer inspector will arrenge to random inspection at
least part of ongoing activity
