Swage Tube Inspection & Asset Integrity Services | NDT Technologies
Fired heaters, boilers, and heat exchangers across petrochemical plants and refineries feature unique geometric configurations where tube diameters are reduced or tapered to fit specialized headers, terminal blocks, or fittings. These transitioned sections are known as swage tubes. Because of their modified cross-sections and precise geometry, swage regions experience distinct mechanical and fluid dynamic stresses. The tapering process alters the local grain structure of the alloy, making it highly vulnerable to localized stresses, accelerated erosion, mechanical fatigue, and thermal shock.
We are industry leaders in pipeline inspection and rehabilitation works, offering intelligent pigging for coiled tubes in the UAE and India
