5/7/2011· P.S.- Refer the allowable steam velocities as given below, 1. Exhaust steam - 20 to 30 m/s (70 - 100 ft/s) 2. Saturated steam - 30 to 40 m/s (100 - 130 ft/s) 3. Superheated steam - 40 to 60 m/s (130 -200 ft/s) In you case it''s superheated steam. If you see the range of allowable velociy as recommended above, you will get a range of flow through
Packless vibration absorbers are constructed with deep pitch corrugated tubing for increased flexibility and vibration absorption. They are covered by high tensile wire braid for superior strength and durability. The vibration absorbers have copper ends for making sweat connections to refrigerant piping.

considered as a failed/degraded tube. For the steam generators of nuclear power stations (thermal reactors), the average tube failure is 0.24 % per year based on plugging rate alone  and 0.4-0.5 % per year based on plugging and sleeving . Although 0.24 %/year may not appear significant, over a 30-40

the discharge piping strains cannot be avoided and have forced the upper portion of the valve out of exact alignment (Fig 4 & 5). 3. The superior strength built into the body of the Farris pressure relief valve to resist these discharge piping strains materially reduces the deflection and distortion in the valve and reduces

Figure 3.1 Steam Phase Diagram For a boiler is operating at a pressure of 8 kg/cm2, steam saturation temperature is 170 oC, and steam enthalpy or total heat of dry saturated steam is given by: h f +h fg = 171.35 +489.46 = 660.81 kCal/kg. If the same steam contains 4% moisture, the total heat of steam is given by: 171.35+ 0.96 x 489.46 = 641.23
Note that the steam loads are the same as Example 14.3.10, but the discharge lines are one size larger due to the rising common line. The procedure shown in Examples 14.3.10 and 14.3.11 can be simplified by using Appendix 14.3.3. For example, where pipes A and B (20 mm and 50 mm) join, the minimum required pipe diameter is shown as 54 mm.
