  • Staying for Construction of Boilers - stay and stays

    These boilers are internally fired, and as the 'variation of temperature causes expansion and contraction, great care should be used in placing the gusset stay. If the stay is too near the flange or too many stays are used, the head will be too rigid and have a tendency to crack.

  • How To Deal With Thermal Pipe Expansion and Contraction - …

    The expansion and contraction of tubes are accommodated by Adamson's flanged ring joint as shown in fig. 4-6. In this joint the end of each ring are flanged outwards and the rings are connected together, end to end, by rivets, passing through flanges. A welded expansion ring is placed between the flanges. It facilitates caulking which gives steam tight joint. In the case of boilers with unstayed dished end …

    This rapid expansion and contraction in the boiler can cause cracks in the steel resulting in water leaking from the tubes and seams. Increases boiler efficiency by tempering the boiler feed water. The lower the boiler feedwater temperature, the more heat is required in the boiler to produce steam.
