tubing fault tree.
CPM,1999,27(5):43~45
The coiled tubing fault tree is constructed based on field investigation and relevant
literature by use of the
fault tree analysis theory. The main failure patterns of coiled tubings are outlined, the failure
causes are discussed
qualitatively and quantitatively, and the main factors influencing the reliability of coiled
tubings are investigated.
By analyzing the structural importance of the coiled tubing fault tree, it is indicated that,
misoperation, corrosion,
cyclic deflection and inner pressure are the main factors causing the premature failure of
coiled tubings, and the
quality and property of material are the vital factors effecting the reliability of coiled tubings.
Thereby the
effective measures for improving the service life of coiled tubings are proposed.
