Seal pots/Condensate chambers are available in carbon steel to ASTM A 106 with Zinga coating equivalent to hot dip galvanized, Epoxy, Silver Coat etc. Stainless Steel to ASTM A 312 Piping code, P22 and other alloy steel fabricated from Seamless pipe with inside cleaned and checked to assure desired volume. Standard pipe sizes are 2" to 6". Connection fittings are NPT or welded socket adaptors, Butt Weld etc. The half coupling connections are jig welded inside and out at 90 degrees to assure safety, provide proper alignment and ease the task of installing.
Initial sizing of the required level in the seal pots is somewhat subjective. The basic rule of thumb is that the level in the chambers should equal the total volume of condensate in the transmitter and the sensing lines. This also complies with ASME requirements. Exact capacity is also contingent on a number of other issues including: Relative humidity, Dew point, Pressure, Flow rate, etc. Standard maintenance includes draining/filling as necessary.
