Common Questions and Practical Solutions
How do I select between 304 and 316L stainless for threaded fittings?
316L provides superior corrosion resistance for exterior and marine applications. 304 works well for interior installations and offers cost savings. Consider total project lifecycle—marine environments require 316L to achieve reasonable service life.
What thread engagement is required for code compliance?
Most building codes require minimum 6 full threads engagement. Industrial applications often specify 8-10 threads. Our engineering team reviews specific code requirements during project planning.
Can threaded cable end fittings handle dynamic loads?
Yes, with proper design. Thread compounds prevent galling under cycling loads. Regular inspection schedules identify wear before failure. Marine applications require more frequent service intervals.
How does custom threaded cable manufacturing compare cost-wise to standard components?
Custom fabrication runs 20-40% higher than catalog items but eliminates field modifications and reduces installation time. Break-even typically occurs around 50-100 pieces depending on complexity.
What’s the realistic maintenance schedule for threaded connections?
Indoor applications: 5-year inspection intervals. Coastal environments: annual inspection recommended. Industrial/chemical exposure: 6-month intervals. Retorquing may be required after initial settling period.
Do you provide installation support and technical guidance?
Our 23 years of manufacturing experience includes extensive field support. We provide installation specifications, torque requirements, and troubleshooting guidance for complex installations.
