| Ferrules & Packings | ||
| Condenser Ferrules Large steam condensing heat exchangers often make use of ferrule fixed tubeplates whereby the tube-to-tubeplate seal is performed using packing rings which are compressed by the screw-in ferrule. This has two major advantages. Firstly, tubes can expand and contract as they heat and cool, a process which could otherwise cause premature failure due to stress cracking. Secondly, worn or failed tubes can be replaced individually more easily than would otherwise be the case. Condenser ferrules are generally made to order and can be ordered with fitting tools. Available materials include Naval Brass (CZ112), 90/10 Copper-Nickel (CN102), 70/30 Copper-Nickel (CN107) and 66/30/2/2 Copper-Nickel (CN108).  | Condenser Packing Rings Crane-type condenser packing rings/seals are generally kept in stock in both fibre and metallic materials.
