Butterworth hatches are not the main access hatches, but are the servicing hatches, and are generally closed with a metal cover plate with a gasket that is fastened to the deck by a number of bolts which stick up from the deck. Holes on the edges of the plate fit over these bolts and the cover is fastened down with nuts or dogs.

Among these techniques hydraulic bulge testing allows for an increased work hardening of sheet material by distinctive stretching operations and provides better shape accuracy for complex parts. Hence, by selecting proper material and the forming parameters for hydraulic sheet bulging study one can determine Forming Limit Curves (FLCs).
The fixed plate is shown in gold and six shafts each take a reciprocating motion from points on the gold plate. The shafts might be connected to pistons in cylinders. Note the power may be coming from the shaft to drive the pistons as in a pump, or from the pistons to drive the shaft rotation as in an engine
A large medium or heavy-duty truck usually consisting of multiple storage compartments, carrying equipment equal to the capabilities of a ladder truck company, but lacking the aerial ladder. Ladder pipe Nozzle attached to an aerial ladder and used to direct heavy stream from advantageous height. Landing valve
A manhole cover is a removable plate forming the lid over the opening of a manhole, an opening large enough for a person to pass through that is used as an access point for an underground vault or pipe. It is designed to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.
The sides of the plates are sealed by seam welding, other than the connecting ports. Finally, the gap between the thin metal sheets is pressurized by a hydraulic fluid causing a plastic forming of the plates, which eventually leads to their characteristic wavy surface. Single embossed pillow plate section.
This results in the projected plate area of the lamella clarifier taking up approximately 50% of the space of a conventional clarifier. [13] [18] Plate spacing: Typical spacing between plates is 50 mm, though plates can be spaced in the range of 50–80 mm apart, given that the particles > 50 mm in size have been removed in pre-treatment stages.
