RTJ vs RF flanges
Can anyone tell me why RTJ flanges are often used over RF Flanges in certain services (eg natural gas) over 900# rating. Is this due to the additional risk of gasket failure in this higher pressure service or are there other factors, for example corrosion with sour gas, which influence the decision away from Spiral Wound gaskets?
