    Steam Corrosion on piping & CF8M castings

    Application is papermaker. Low Pressure Steam is not corrosive to the steam piping [mild steel] or the paper machines dryer cans [cast iron]. Why is steam so corrosive to our CF8M electropolished castings? [very serious corrosion] Even the SS316L polished shaft is very corroded - why? Could the...

    SS 304L Substitution with SS201LN

    We supply equipment to the paper industry and use SS304L and 316L exclusively. We have been approached to use cheaper SS201LN and AL2003. No problems structurally, but, anti-corrosion has me worried. How will this compare when exposed to caustic boil-outs + chlorides/chlorines and various...

    steam separator

    How do we know we have the right fitting?

    There has been mention of not using a weldolet on thin pipes. I have seen no mention of this from Bonney F. The 20" sch. 10 pipe has a wall thk of 1/4". Is this not sufficient? I have used weldolets for joining 8" sch. 10 [thk of 0.148"]with 3" sch. 40 pipe with no...

    Pressure class piping

    Designing a pressure piping system to operate at maximum 16 psi. Need to use 8" pipe, but sch. 40 is way too thick and heavy. Would like to use sch. 20s pipe.[1/4" wall]. only up to 16 psi steam [300F]. Any documentation that will permit use of sch. 20S pipe instead of 40? ie, any...
