Use FOB(flat on bottom) eccentric reducers if there is drain in the same line
Use FOT(flat on top) eccentric reducers in pump suction line to avoid accumulation of gas pockets.
Use eccentric reducers are for slurry systems and where it is imperative to totally drain ALL condensed fluid, eccentric reducers can avoid small “dead spots” that
exist behind concentric reducers
Expansion joint used to absorb thermal expansion if the use of expansion loops is undesirable or impractical
Valve selection according to (pressure drop, seat leakage, fluid properties, system leakage, actuation requirements, initial cost & maintenance)
Stop valve=Isolation valve=Division valve & can be (gate, globe, ball, butterfly, plug & diaphragm)
Piping material selection according to (flow medium, operating condition, life time, fabrication & most economical)
Insulating flange kits include gasket, sleeve & washer are provided to prevent galvanic corrosion between dissimilar metals check detail
Stainless steel pipe to be isolated from steel supports by red rubber tape or stainless steel shims
Allowable stresses. B31.1 allowable are lower than B31.3 because b31.3 plants generally have a plant life of about 20 to 30 years. B31.1 on the other is about 40 years, B31.1 is MORE conservative than B31.3
