This type of erosion may be ignored but needs to be monitored during next overhauling as this erosion is just started or erosion is due to small misalignment of the tubes.
An O-type boiler is a form of water-tube boiler.It is named, like the D-type and A-type boilers, from the approximate shape of its tubes.. They are characterised by single steam and water drums vertically above each other, with curved vertical water tubes to the sides forming an overall cylindrical volume.
designed with 2 in. (5.08 cm) tubes spaced 2 in. (5.08 cm) apart (tube section in foreground). This helps to prevent membrane thermal cracking and contributes to a faster load response. B&W’s water-tube package boiler offers more water-cooled surface, which in turn helps to meet today’s stringent emissions regulations.
Oct 27, 2018 · Generally, boiler pipe can be manufactured from an extensive range of pipe materials that contain high and low yield stainless steels, alloy steels, carbon steels, titanium and Cr-Ni alloys.
The heat transfer tubes of the watertube boiler vary across the circumferential span of the drums: there may be eleven or more differing tube types to assemble in a single watertube unit. In the firetube, each heat transfer tube is identical to its counterparts. Manufacture and service are readily accomplished with a stock of a single tube type.

Therefore, boiler tubes usually fail from caustic embrittlement at points where tubes are rolled into sheets, drums, or headers. The possibility of embrittlement may not be ignored even when the boiler is of an all-welded design. Cracked welds or tube-end leakage can provide the mechanism by which drum metal may be adversely affected.
