Frequently Asked Questions
What grade of stainless steel is used?
Our threaded round nipples are made from AISI 316L (UNS S31603) stainless steel, which offers superior corrosion resistance to chlorides and marine atmospheres, making it the preferred choice for shipboard applications.
What thread standards are available?
We supply nipples with NPT (American National Standard Taper Pipe Threads) and BSP (British Standard Pipe) threads. Both types are available in standard sizes, and custom dimensions can be quoted upon request.
What pressure rating can these nipples handle?
Depending on the size and schedule (40 or 80), these nipples are rated for working pressures up to 3000 psi. Always verify the exact pressure rating for your specific configuration before installation.
Can I order non-standard sizes for specific shipboard piping?
Yes, we can manufacture round nipples in custom lengths, diameters, and thread configurations to meet your vessel's requirements. Contact our ship chandler team with your specifications for a quote.
