This occurs when there is excessive deposition on the internal diameter of the seamless tube. Contact surface area is reduced which causes diminished cooling and localized boiling beneath the deposit. If chemistry upsets occur, and the PH level becomes high a caustic condition can occur which corrosively attacks the protective magnetite. Wall loss can occur very rapidly. https://goo.gl/UZ4Kz3

Water tube consist of a series of boiler tubes in which water circulates. As the water passes through the tubes, the water is warmed and turns to steam. Frequently a superheater is fitted, to warm steam further into a dry type. This helps avert water related damage, including turbines in power stations, on process equipment that is commonly expensive. Typically water tube boilers are used in industries including power generation (nearly exclusively), and marine uses, due to their capability to function at function at higher pressures. The inspection of boiler tubes is of significance for many reasons. In the electricity generation sector especially, efficacy is a driving factor. Due to the big profits involved, even modest improvements in efficiency or modest changes down time can create drastic changes in earnings. Security is perhaps the largest, with routine review helping prevent another driving factor, blow outs and potentially fatal accidents from happening. Review is done via non-destructive techniques, utilising "Non-Destructive Testing". Technologies including ultrasonic and electromagnetic are ordinarily employed, and can provide the rest of the thickness of the seamless tube walls, in addition to details of the defects themselves. Visual inspection is more difficult to reach places and also accustomed to identify any clear problem areas in conjunction with borescopes for internal review. Various areas of the boiler can be scrutinized, from boiler generating banks, to waterwall tubes. Straight sections and bend sections could be analyzed, and defects uncovered and quantified. Superheaters, reheaters and economisers may also be scrutinized. Tube groundwork varies on the technology used, and is of concern also. With ultrasonic techniques, a clean surface and good contact is necessary, so tubes will need to be cleaned to a high standard in the right review times. Other technologies such as with LFET (Low Frequency Electromagnetic Technique) require less preparation, with a small uniform scale not an issue. Nonetheless, nonuniform scales can be problematic, due to issues with lift off
Seamless Tube conduit is a continuous extrusion of the alloy, meaning that it will have a round cross section that you can count on, which is helpful when you’re installing pipes or adding fittings. The pipe can sometimes be more expensive than other forms of steel pipe, but it’s also more dependable.It is because it's greater durability under load. When a pipe is full of material–or under load–it must additionally support that weight as well, although empty conduit should support its own weight. https://goo.gl/vnR5Bi
