FAQ
Q: Why do I need to specify the "Schedule" for a Weld Neck flange?
A: Since the flange is welded end-to-end with the pipe, the internal bores must match. If the bores are different, it creates flow turbulence and complicates the welding process.
Q: What's the difference between RF and RTJ facing?
A: RF (Raised Face) uses gaskets for sealing and suits most standard applications. RTJ (Ring Type Joint) provides metal-to-metal sealing for high-pressure services above 600# class.
Q: How do you ensure proper fit with my existing piping?
A: We machine the bore to match your specified pipe schedule exactly. Providing your pipe outside diameter and wall thickness ensures perfect alignment.
Q: What testing documentation do you provide?
A: Each order includes material test certificates showing chemical composition and mechanical properties, plus dimensional inspection reports confirming ASME compliance.
