A boiler stay is an internal structural element of a boiler. Where the shell of a boiler or other pressure vessel is made of cylindrical or (part) spherical elements, the internal pressure will be contained without distortion. However, flat surfaces of any significant size will distort under pressure, tending to bulge. Stays of various types are used to support these surfaces by tying them together to resist pressure. Some boiler configurations require a great deal of staying. A large locomotive boiler may require several thousand stays to support the firebox. In water tube boilers, stays were sometimes used between their main chambers, and could themselves be water tubes.

Where the shell of a boiler or other pressure vessel is made of cylindrical or (part) spherical elements, the internal pressure will be contained without distortion. However, flat surfaces of any significant size will distort under pressure, tending to bulge. Stays of various types are used to support these surfaces by tying them together to resist pressure.

  • Stehbolzen sind Metallbolzen, die mit einer ihrer Schnittkreisflächen fest mit einem Bauteil verbunden sind und somit auf diesem „stehen“. Über die Stehbolzen können dann weitere Bauteile mit dem ersten verbunden werden. Sie dienen als Befestigungsteile in vielen Bereichen des Maschinenbaus und der Elektrotechnik. Es gibt sie mit und ohne Gewinde. (de)
