Pressure Vessel Codes :

Al-Subuk Pressure Vessel has been designed and constructed in accordance with the ASME Section VIII Division I Code latest edition and Pressure Vessel Inspectors. AL-Subuk has also the capability to design and construct customized pressure vessels as per customer demand. 

 INSTALLATION RECOMMENDATIONS Vertical Vessels:

 Vessels with a capacity of 660 gallons and above should be placed on a suitable concrete foundation.

• a) Refer to Table 1 for recommended minimum concrete footing depths for vertical receivers.
• b) For larger vessels or vessels with higher MAWP’s, greater weights, or vessels subjected to external seismic or wind loadings – consult a certified contractor or civil engineer for foundation requirements.
• c) Vessels should be lifted into position using both lifting lugs. A 2-branch chain or wire rope sling should be used having a lift angle not less than 60 degrees from grade. Once the vessel is in position, torque anchor bolting until a tight, a snug fit is achieved.

Useful Formulas - Sizing a Tank:

• A : Constant Speed Operation: Tank Size (ft3) = Compressor Flow (CFM

                                                                                                           7

• B: Typical Sizing Formula: VR = 14.7 t (Qr-Qc  where

                                                                  Pmax - Pmin

• C: 7.48 Gallons = 1 ft3 Volume
• D: 14.5 psi = Ba
• E: 5 CFM = 1 Meter3

                                   min

• F: pump Up Time: Example - 5 hp compressor on an 80 gallon tank, pumping from 0-100 psig

80 Gallon Tank  X (100 psig - 0 psig) =                                             1066.67                                           = 4 min

      7.5 gl./ft3                                                  14.7 (the ATM Pressure) X 18 (the CFM of Unit)                

Gallons =    Cu.Ft    ...Cu.Ft  = Gallon X 0.134

                   0.134
