To capture demographic changes in above models the study has used population growth (PG) rate and middle age working population portion (MAWP
* Static (leak checks or proof tests): Requires pressure at the MAWP
to verify that the hose will not rupture and the assembly (i.e., crimp area) does not leak.
Considering a boiler with a MAWP
of 30 psig (207 kPa) and having a set pressure of 10 psig + 5 psig = 15 psig (69 kPa + 34 kPa = 103 kPa) requires an expansion tank large enough to limit the pressure increase to 15 psig (103 kPa).
The sub-microfacies types are recognized based on the second dominant constituents such as bivalves in BiMWP, algae in AWP, Orbitoididea in OMWP, Miscellanea in MAWP
and in MBWP sub-microfacies.
Each component of the Crystal Pressure Fittings (CPF) line of hoses and fittings performs at up to 10,000 psi (MAWP
), with a 4:1 Safety Factor, and features a Safety Weep Hole to warn against disconnections while a system remains under pressure.
Company's horizontal firetube boilers feature a three-pass wet-back design, and are offered with an open protocol burner with a pressure rating up to 300 psig MAWP
. A PLC (programmable logic controller) boiler control system shows operators the current boiler status, providing high-tech display parameters for burner firing rate, stack temperature, steam pressure, boiler water temperature and stack oxygen levels.
The set pressure of the relief device applied to protect a vessel cannot be greater than the vessel's maximum allowable working pressure (MAWP
), as stamped on the vessel's data tag, but it can be less.
PRIORITY RESPONSE TIME EXAMPLE OF CONDITION MATCHING PRIORITY 1--Urgent 24 hours Actual thickness is below the calculated tmin The PSV and/or MOP are unknown or above the calculated MAWP
2--Action 30 days Insulation not weather sealed with heavy 3--Caution 90-180 days corrosion.
Gross volume: 530 cubic meters Outer diameter: 5,000 mm Approximate length: 36,000 mm MAWP

The failure state corresponds to breakage or leakage of the pipeline and the limited state is defined as when the maximum allowable working pressure (MAWP
) falls to the design pressure.
