An overview of the nondestructive inspection techniques for coiled tubing and pipe
- Quality Tubing, Inc., Houston, TX (United States)
Coiled steel tubing and pipe in the diameter range 20--90 mm (0.75--3.5 in.) are replacing conventional oilfield materials for a variety of purposes including workovers, drilling, production tubing, umbilicals, and flowlines. They offer all the advantages of long tubes with no threaded connections. Because coiled tubing is being produced to high quality standards, it is lasting longer than ever before, and the need has arisen for careful nondestructive inspection at frequent intervals to determine accumulated damage to the string and the need for repair. Currently, derating of used coiled tubing using nondestructive testing (NDT) is not performed. While NDT devices for oilfield tubulars have been well documented, little has been written regarding the NDT of coiled tubing. This paper outlines the current NDT methods used during the manufacture of new tubing and the inspection of used coiled tubing.
