2000年8月27日 · Some of them, with B7 in the group, are classified as high strength and may be used with any flange material within the specified temperature limits, whilst others, and among them most stainless steel materials, are classified as intermediate strength, that need a check of their ability to sustain the gasket seating condition (separate from the ...

2014年8月8日 · I have a 3" pipe spool with a carbon steel WN RF CL150 flange (ASTM A105) and it needs to be bolted to a mating CL150 flange made of stainless steel (ASTM A182). Are there any practices that I should be aware of, to prevent galvanic corrosion, when bolting the two dissimilar flanges together...

2010年7月20日 · Is it possible to connect a stainless steel flange to carbon steel flange (24" piping) with river water as the flowing fluid? what type of problem would the...

2024年11月6日 · If your still wanting to use flanges, weld a 150# S.S. flange to the stainless and use a “Flange Adapter”” on the D.I. pipe. The adapter slides over the plain end of the D.I. and secures with set screws and seals with an O-Ring. The 125# adapter will mate with the 150# S.S. flange. This will provide a restrained connection.

2010年2月23日 · Despite the potential problems, the use of B7 bolts with stainless steel piping in near ambient temperature dry applications is relatively common. For example, the Process Industry Practices (PIP) piping line classes for SS specify B7 bolting.

2006年3月26日 · For conductive, corrosive fluids, suitable insulation may need to be incorporated and/or a corrosion allowance provided on the carbon steel in and around the joint. For atmospheric exposure, carbon/low alloy steel bolting is a viable, albeit visually ugly, option (don't galvanise the bolts if liquid metal embrittlement scenarios cannot be ...

2010年3月18日 · A cone of stainless steel rods was installed downstream of the filter and was found to be effective in discharging the static charges. This line did not have insulated joints. When you consider the number of metal to metal current paths provided by the flange bolts of a flanged connection, grounding seems superfluous.

2011年10月3日 · I would like to add that if you use Stainless Steel bolting with your stainless steel flange (a common scenario), the torque values in Table 1 of PCC-1 2010 won't be directly applicable. Those are based on Coefficients of Friction of 0.16 and 0.12, which by the guidelines of Appendix K give nut factors of 0.2 and 0.16 respectively.

2022年12月13日 · Although the silicon bronze and the stainless steel bolts lost the least amount of weight during the study, they caused severe corrosion of the nearby glands. As a result of these tests, most pipe manufacturers began to recommend the use of low alloy steel bolts over high strength gray-iron with 0.5% Cu.

2007年12月11日 · I am designing a plant where there is a water tank in Stainless steel 316 with a 6" flanged opening on the top. I am planning to mount an aluminium element on that flange. Thus there will be two flanges put together, one in SS, and the other one in aluminium. Bolts, washers and nuts will be in SS also.
