Type S : Standard balls: P : Extended life balls R : Abrasive balls Specification T : Standard G : Polishing Y : Fully Coated Z : Ring Coated with Corundum X : Blended with Corundum Diameter From 16 to 42 mm Increment 1 mm Specific diameter available on request Hardness J : Soft N : Medium-Soft F : Medium-Hard H : Hard Temperature 1 : Standard balls up to 80°C 2 : Heat resistant balls up to 140°C 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 BALL TYPE Standard (S) Used continuously in normal conditions for operation in freshwater or sea water. Soft for brass tubes, soft or hard for SS or titanium tubes. Extended life (P) Used when water fouling is not severe and can be wiped out easily. The spongy structure has a thin smooth layer which wears out slowly to extend lifetime. Heavy Duty Designed to solve the most difficult cases. The balls contain a mixture of polishing agent and rubber, ensuring a continuous and constant efficiency without causing damage to the tube structure Abrasive balls (R) Used in specific conditions for a short time period. The carborundum content in the balls abrades hard deposits. The use of these type of balls are recommended only when the CTCS does not run continuously and are manufactured only upon request. They are available in three different grades : - Fully coated (Y) - Ring coated with Corundum (Z) - Blended with Corundum (X) System 5000 V2 Multi-Beam Side Scan Sonar System 4900 Side Scan Sonar for Survey & Recovery Applications System 3000 Digital Side Scan Sonar System 3000H Digital Side Scan Sonar System 3900 Digital Side Scan Sonar HYDROCHART 3500 Hydrographic Survey System HYDROCHART 5000 Hydrographic Survey System AUV/UUV System 5000 V2 Multi-Beam Side Scan Sonar AUV/UUV 3500 High-Resolution Side Scan Sonar K-Chirp Model 3310 Sub Bottom Profiler klein3000侧扫声纳 klein5000侧扫声纳 Edgetech侧扫声纳4200 Edgetech侧扫声纳2205 Klein测深声纳UUV3500 Edgetech测深声纳6205 Klein跨接缆 Klein多路通信板 klein紧固件
