FIG. 3 is a perspective view of the milling machine and air drive used to mill elongated slots in boiler tubes, shown mounted on the furnace boiler water wall. FIG. 4 is a perspective view of the drill and fixture used to make a starting hole for cutting the boiler tube.
Boiler tubes are a key component of steam power and as such are subjected to terrible force. This means that boiler tube weld inspection is crucial to keeping mission-critical operations safe. Over time, phased array ultrasonic testing (PAUT) has emerged as one of the best means of non-destructive testing (NDT) of boiler tubes.

A boiler is a closed device that heats fluid (usually water) in. Don't actually steam the gas. The heated or vaporized fluid leaves the boiler relying on Boiler tubes, cooking, and sanitation for use in different processes or heating applications such as water heating, central heating, power generation.

drum boiler, the generating bank tubes are connected to headers and the gas flows parallel to the tube. In a two-drum boiler the tubes are connected to the steam drum and the mud drum and the gas passes through in cross-flow. Older economizer designs used baffles to obtain a cross-flow of hot gas over the economizer tubes. More modern
In spiral welded pipe technology, forming angle is an important parameter, which refers to the angle (acute angle) helical axis of spiral welded steel production (tube) after welding and forming the center line between it and the strip (tube) width, coil diameter, stress and productivity have a certain relationship. Relationship with the strip forming angle (tube) width …

1. Production method of high pressure boiler tube: ①Generally, the temperature of boiler tubes is below 450℃. Domestic tubes are mainly made of No. 10 and No. 20 carbon steel hot-rolled tubes or cold-drawn tubes. ②High-pressure boiler tubes are often in high temperature and high pressure conditions when they are used.
Assuming you have the tubes out measure the holes. The proper tubes are S A 178-A and in your case 3 inch. The new tubes should be within a couple of thousands of 3 inches probably under. If your boiler was designed for ferules the tube holes will be 3 and 1/8 inches for 62.5 [1/16 ]inch wall ferules.

THE RESULTS. Gecko Robotics completed the inspection in four days, gathering over 12 million readings. Through this, they achieved 99% coverage of the entire boiler at six different angles on each tube. Without this high-density coverage data, the boiler's eventual tube failure would have caused an explosion within the paper mill.
