The copper pipe penetration is firestopped with firestop mortar. Riser clamp for a standpipe through-penetration firestop inside a fire hose cabinet under construction A riser clamp is a type of hardware used by mechanical building trades for pipe support in vertical runs of piping (risers) at each floor level.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
The material with which a pipe is manufactured is often the basis for choosing a pipe. Materials used for manufacturing pipes include: Carbon (CS) and galvanized steel; Impact-tested carbon steel (ITCS) Low-temperature carbon steel (LTCS) Stainless steel (SS) Malleable iron; Chrome-molybdenum (alloy) steel (generally used for high-temperature ...
Insulated hot water supply and return hydronic piping on a gas-fired boiler. Since pipework can operate at temperatures far removed from the ambient temperature, and the rate of heat flow from a pipe is related to the temperature differential between the pipe and the surrounding ambient air, heat flow from pipework can be considerable.

A thermo-hygrograph. A thermo-hygrograph or hygrothermograph is a chart recorder that measures and records both temperature and humidity (or dew point).Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity.
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
An example of a heat number on a plate. A heat number is a unique identification coupon number that is stamped on a material plate after it is removed from the ladle and rolled at a steel mill.
