Please refer to the latest standards for details. Selected materials also conform to NACE MR0103.HART 5 or HART 7 is selectable. Specify upon ordering.Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the diaphragm itself can be damaged and that material from the broken diaphragm and the fill fluid can contaminate the user’s process fluids.Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high-temperature steam (150°C [302°F] or above). Contact Yokogawa for detailed information of the wetted parts material.Cast version of 316 SST. Equivalent to SCS14A.Intergranular corrosion test passed according to ASTM A262 Practice E.Hastelloy C-276 or ASTM N10276.Material of a blind plug; aluminum alloy for code 5 and 9, and SUS304 for code 7.Applicable for Electrical connection code 2, 4, 7, 9, C and D.Lower limit of temperature is -15°C (5°F) when option code HE is specified.
