2. Steam-powered vessel - Wikipedia

   en.wikipedia.org/wiki/Steam-powered_vessel

   High temperature steam can cause injury in humans on areas of exposed skin or by other means. Steam can cause burns through direct contact or by inhalation of vapors. [7] Steam boilers also present an explosion hazard due to their high pressure contents. If over pressurization occurs and safety relief systems malfunction it is possible for a ...

3. Hose clamp - Wikipedia

   en.wikipedia.org/wiki/Hose_clamp

   For these high pressure applications, compression fittings, thick crimp fittings, or other designs are normally used. Hose clamps are frequently used for things other than their intended use, and are often used as a more permanent version of duct tape wherever a tightening band around something would be useful. The screw band type in particular ...

4. Steamboat - Wikipedia

   en.wikipedia.org/wiki/Steamboat

   The high-pressure steam engine was the development that made the steamboat practical. It had a high power-to-weight ratio and was fuel efficient. High pressure engines were made possible by improvements in the design of boilers and engine components so that they could withstand internal pressure, although boiler explosions were common due to ...

5. Marine propulsion - Wikipedia

   en.wikipedia.org/wiki/Marine_propulsion

   One high-profile example was the 1968 built Queen Elizabeth 2 which had her steam turbines replaced with a diesel-electric propulsion plant in 1986. Most new-build ships with steam turbines are specialist vessels such as nuclear-powered vessels, and certain merchant vessels (notably Liquefied Natural Gas (LNG) and coal carriers) where the cargo ...

6. Marine steam engine - Wikipedia

   en.wikipedia.org/wiki/Marine_steam_engine

   From the first Royal Navy steam vessel in 1820 until 1840, 70 steam vessels entered service, the majority with side-lever engines, using boilers set to 4psi maximum pressure. [8] The low steam pressures dictated the large cylinder sizes for the side-lever engines, though the effective pressure on the piston was the difference between the boiler ...

7. Pipe support - Wikipedia

   en.wikipedia.org/wiki/Pipe_support

   Internal or external pressure induces stresses in the axial as well as circumferential (Cylinder stress Hoop Stress) directions. The pressure also induces stresses in the radial direction, but these are often neglected. The internal pressure exerts an axial force equal to pressure times the internal cross section of the pipe. F =P[πd^2/4].

9. Boat building - Wikipedia

   en.wikipedia.org/wiki/Boat_building

   Sheet plywood boat building uses sheets of plywood panels usually fixed to longitudinal long wood such the chines, inwhales (sheer clamps) or intermediate stringers which are all bent around a series of frames. By attaching the ply sheets to the longwood rather than directly to the frames this avoids hard spots or an unfair hull.
