SYSTEM DESIGN 6 Sizing Superheated Mains Sizing Superheated Mains When sizing steam mains for superheated service, the following procedure should be used. Divide the required flow rate by the factor in Table 2. This will give an equivalent saturated steam flow. Enter Fig. 1, Steam Velocity Chart on page 4 to select appropriate pipe size. If unable, then use the formula on page 3 to calculate cross sectional area of the pipe and then Tables 38 and 39, page 81, to select the pipe size which closely matches calculated internal transverse area. Example: Size a steam main to carry 34,000 lb/h of 300 psig steam at a temperature of 500° F. From Table 2 the correction factor is .96. The equivalent capacity is 34,000 = 35,417 lb/h. .96 Since 300 psig is not found on Fig. 1, the pipe size will have to be calculated. From the formula on page 3: 2.4 x Q x Vs V = A Solving for area the formula becomes: 2.4 x Q x Vs A = V Table 2: Superheated Steam Correction Factor Select a velocity of 10,000 ft/min. (which is within the process velocity range of 8,000 - 12,000 ft/min.) and determine Vs (specific volume) of 1.47 ft 3 /lb (from the Steam Table on page 7). The formula is now: A = 2.4 x 35,417 x 1.47 = 12.5 in 2 10,000 From Tables 38 and 39 (page 81) the pipe closest to this area is 4" schedule 40 or 5" schedule 80. Gauge Saturated Pressure Temp.
