BALL SIZE Balls must be slightly oversized (2 mm larger) to apply enough pressure inside the tube to ensure correct cleaning. This rule can be changed for specific reasons Larger diameter : used for a longer ball-life when the condenser pressure drop is higher than usual. This applies only when the type of fouling allows the use of soft or medium soft cleaning balls. In other cases, the use of extra oversized balls can lead to ball blockage inside condenser tubes, reducing the heat exchange surface and triggering tube corrosion. For the above reason, balls must not swell due to a chemical reaction with water. Smaller diameter : when using abrasive coated balls or when condensers are equipped with protective nozzles or when the CTCS design does not prevent the risk of the ball becoming wedged between the strainer bars. In this last case, the use of harder but smaller balls can be convenient. ­Technos天可诺海绵胶球 ST26N1 法国天可诺中软标准球ST26N1 technos  型号ST25N1胶球 法国technos 胶球直径Φ25 法国天可诺technos 胶球直径Φ25Cameron分配块 08T 分配块\CT0912/MH62 25T  分配块\CT0912/MH62 08T 分配块\CT0912/MH62 16T  分配块\CT0912/MH62 08S 注油器泵头\CT0912/MH62 3/16"  注油器分配器\CT0912/MH62   VACUUM TOILET SYSTEM     MAKER: EVAC      ITEM P/N DN DESCRIPTION QTY UNIT  EVAC 真空集便器 EVAC 真空厕所配件排放阀   dnh 15W室外喇叭HS-15EExmNT calgaz标准气体 CH4,2.5%(50%LEL)   阿美特克AMETEK分析仪 温控器 akron阿密龙喷嘴带管子 4470   OTECO安全阀130367美国原装 MUSTANG 野马工作救生衣SURVIVAL MV3092 evac 真空马桶配件排放阀         SWACO压板 Elomek 720 24VDC+Armature 722      Schmitz清洁胶球24RB20M0    MMC储油罐电子检尺仪D2401-2   美国阿密龙消防炮头4827  美国阿密龙自摆消防炮911+4827    EVAC厕所马桶配件单向阀  VERSA 气控电磁阀VSP VERSA 气控阀VSP 美国进口 VERSA 气控阀BB-3-316 BB-3-316 ARNA AUTRONICA 手动报警按钮 BF-300V2威创 302ANGX1489   威创 传感器302ANGX1489 Viatran传感器302ANGX1489 威创压力传感器302ANGX1489   Viatran传感器302ARGX1489A   威创压力传感器302ARGX1489A   威创传感器302ARGX1489A   美国viatran威创传感器2476ACGDMTU Viatran 520BQS 威创 5705BPSX1051 威创 5093BMST85   Viatran 5093BPSZQ  Viatran  型号510BPST25A  威创传感器 5705BPSX1051 Viatran 压力变送器509   P/N:5093BPS   S/N:486284M
