Frequently asked questions
Common questions about GOODWAY from 3G Electric.
What are the key specifications of Goodway flexible shafts for heat exchanger cleaning?
Goodway flexible shafts are constructed from nylon and steel, designed to transmit rotational force to cleaning tools. They accommodate tube diameters from 9/16 inch to 1 inch, with overall lengths available in 25 ft, 45 ft, and 60 ft. Maximum fluid temperature is 120°F. Some models support a maximum flow rate of 1.9 gpm, while others are rated at 0.6 gpm. Connection types include female threaded (1/4-28) and female quick-connect fittings. Shafts are available for smooth bore and enhanced tube types. Manufacturer part numbers include GTC-703-25, GTC-703-35, GTC-703Q-45, and GTC-702-25.
How do I select the correct Goodway flexible shaft for my heat exchanger tubes?
Selection depends on tube diameter, tube type (smooth bore or enhanced), required length, and connection type. For tube diameters from 9/16 inch to 1 inch, shafts like GTC-703-25 or GTC-703Q-25 are suitable. For smaller tubes (7/16 inch to 1/2 inch), GTC-702-25 is appropriate. Enhanced tubes require shafts specifically designed for them, such as GTC-703Q-45. Length should match the distance to be cleaned, with options from 25 ft to 60 ft. Connection type must match the cleaning tool or drive unit. Always verify maximum fluid temperature (120°F) and flow rate compatibility.
What is the maximum fluid temperature for Goodway heat exchanger cleaning shafts?
Goodway flexible shafts for heat exchanger cleaning are rated for a maximum fluid temperature of 120°F (49°C). This limit applies to all models in the supplied range, including GTC-703-25, GTC-703-35, GTC-703Q-45, and GTC-702-25. Operating above this temperature may compromise the nylon and steel construction, leading to premature wear or failure. It is important to ensure that the cleaning process, including any flushing fluids, remains within this temperature limit. For applications requiring higher temperatures, alternative cleaning methods or equipment may be necessary.
What types of tubes can Goodway flexible shafts clean?
Goodway flexible shafts are designed for cleaning both smooth bore and enhanced tubes in heat exchangers, condensers, and boilers. Smooth bore tubes are standard cylindrical tubes, while enhanced tubes have internal features such as fins or ridges to improve heat transfer. Shafts for enhanced tubes, like GTC-703Q-45 and GTC-703Q-60, are specifically constructed to navigate these internal structures without damaging them. Shafts for smooth bore tubes, such as GTC-703Q-45 (also suitable for smooth bore), are used for standard cleaning. Always match the shaft to the tube type to ensure effective cleaning and avoid damage.
What connection types are available on Goodway flexible shafts?
Goodway flexible shafts are available with different connection types to interface with cleaning tools and drive units. Common connections include female threaded (1/4-28) and female quick-connect fittings. For example, GTC-703-25 and GTC-703-35 have a 1/4-28 female threaded connection, while GTC-703Q-45 and GTC-703Q-60 feature a female quick-connect fitting. The connection type must be compatible with the cleaning tool or shaft driver being used. Quick-connect fittings allow for faster tool changes, while threaded connections provide a secure, positive engagement. Verify compatibility before ordering.
