The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR0175/ISO 15156. Please refer to the latest standards for details. Selected materials also conform to NACE MR0103.
The “•” marks indicate the most typical selection for each specification.
Users must consider the characteristics of selected wetted parts material and influence of process fluids. Specifying inappropriate materials has the potential to cause serious damage to human body and plant facilities resulted from an unexpected leak of the corrosive process fluids.
Intergranular corrosion test passed according to ASTM A262 Practice E.
Cast version of 316 SST. Equivalent to SCS14A.
Hastelloy C-276 or ASTM N10276.
Specify the process connections code 3 or 4, when using the process connector for D capsule. Without the process connector, use the 1/4 NPT male piping to directly connect to the cover flange.
Lower limit of ambient and process temperature is -15°C for capsule code C.
Material of a blind plug; aluminum alloy for code 5 and 9, and SUS304 for code 7.
Not applicable for output signal code G.
Applicable for Electrical connection code 2, 4, 7, 9, C and D.
Lower limit of ambient temperature is –15°C (5°F) when /HE is specified.
The unit of MWP (Max. working pressure) on the name plate of a housing is the same unit as specified by option codes D1, D3, and D4.
