  1. THE PIPINGSYSTEMS Piping network

  2. Compressor room Inlet and Main drain Adapted tank Flexibles Bucled main ring Isolating valves Air drops Global piping network design

  3. Compressor room Flexibles Compressor room should be : Large for an easy maintenance : Insulated and with a good aeration Flexibles will allow to : Move easily the different machines : Stop vibrations transmission Global piping network design

  4. Main drain Adapted tank Tank will be well adapted : Compressor flow in L/mn : 3 = tank volume in liters Main drain and valve : Drain can be at the tank or down the ring inlet : Will eliminate the first condensates before coming in the piping Global piping network design

  5. Isolating valves Bucled main ring Buckled main ring : Better flow at any point of the network : Pression is equal all along the pipe. Isolating valves : Allow a ring portion isolation for maintenance or modifications Global piping network design

  6. Air drops Air drops : Adapted diameter (20 mm is advised) : A good number of drops will avoid too many flexibles on the floor. Global piping network design

  7. 1) Flow calculation : CV x 7 = M3/h KW x 10 = M3/h 2) Pipe lenght : Mesure the maximum lenght between the air inlet and the furthest air drop. 3) Pipe diameter : Pipe diameter (mm*) Line lenght (*) SCFM x 1,7 = m3/h Piping network calculation

  8. Wall supports Expansion flexibles 1) Wall supports : Each 3 meters 2) Main line : Don ’t forget expansion flexibles for lenght more than 40 - 50 m 3) Drops : Blow chips before mounting the couplers or others accessories The mounting

  9. The Prevost ALR connection system Polyamid nut 316 L Stainless steel teeth ring Polyamid pushing ring nitril O ’ring Polyamid body The ALR system

  10. The Prevost ALR drop system Air pipe Air outlet Condensation Drilling guide A curved pipe can be necessar to reach the wall The airdrop design

  11. The Prevost ALR drop system 3 : Tight the screw 1 : Drill 2 : Rotation 180° Positioning mark The airdrop design

  12. The Prevost ALR drop system 1/2 or 3/4 Inlet metal insert Easy mounting Angle : 45° lateral and 45° vertical 1/2 outlet metal inserts Drain in option 120 / 150 cm The airdrop design

  13. The Prevost ALR Technical Data 1) Aluminium pipe : Aluminium 6060 alloy. Density 2,7 kg / dm3 2) Surfaces treatment : Chromophosphatizing treatment of inside and outside surfaces 3) Coloration pipe : Standard blue electropainting 4) Composite connectors : Thermoplastic technopolymere compounds 5) Connectors metal parts : AISI 316 and AISI 403 stainless steel standards 6) Seals material : Nitrile rubber (NBR) 7) Temperatures : -20 C° to +70 C° 8) Expansion : DL = 0,024 x L x DT° 9) Fluids transported : Compressed air, water, drinking water, alimentary liquids The ALR system

  14. The Prevost ALR standards 1) Aluminium pipe : UNI standard 9006 / 1 2) Pipes and fittings : ISO 727, DIN 8063, NF T54028, KIWA 54, UNI 7441-75 & UNI 7442-75 3) Cylindrical threading : ISO 228 / 1, DIN 2999, UNI 338, BS 21 4) Valves : UNI 8470, UNI 8471 5) Connectors metal parts : AISI 316 and AISI 403 stainless steel standards The ALR system

  15. EXAMPLE OF CALCULATION The ALR system

  16. Outlet 1 ’ ’1/4 BSP Femelle The ALR system

  17. Step 1 : The supports ( 36m x 2 ) + ( 30m x 2 ) = 126m for the main ring 126m / 3 = 42 supports The ALR system

  18. Step 2 : The main ring 126m / 2 ( Bucled loop ) = 63m 126m / 4 = 32 tubes => Diameter = 40 mm Unions will be : ALR UN40 ( 30 pieces ) 35 ( cv ) x 7 = 245 M3/h flow The ALR system

  19. Step 3 : The flexibles Flexibles will be : FLEX FFT 34 (4 pieces ) Diameter corresponding to 40mm = 1 ’ ’ Corresponding connectors will be : ALR PM4034 ( 8 pieces ) The ALR system

  20. Step 4 : The isolating valves Valve corresponding to 40mm = ALR VA40 ( 4 pieces ) The ALR system

  21. Step 5 : The drops The drop tubes will be : ALR TU20 ( 8 pieces ) Drops diameter = The most frequently 20mm The drop connector will be : ALR BP 4020 ( 8 pieces ) The ALR system

  22. Step 5 : The drops 1) Drop connector : ALR BP4020 2) Male threaded connector : ALR PM4034 3) Wall support : AVR Y 1212P The ALR system

  23. Step 6 : The inlet pipe Inlet pipe diameter = 40mm The tank outlet is 1 ’ ’1/4 femelle thread The ALR system

  24. Step 6 : The inlet pipe 1) Equal TEE connector : ALR TE40 2) Main valve : ALR VA40 3) Equal TEE connector : ALR TE40 4) Male threaded connector : ALR PM4034 5) Flexible : FLEX FFT42 6) Main drain valve : ALR VA40 The ALR system
