Seeking help with tube fitting issues in the PL52 mechanical seal auxiliary system?
Thread Content
Dear sea friends, after converting a single-seal device to a double-seal one, all the pipeline connections for the 52-seal tanks (Made in Japan) use this type of fitting; one end of the fitting is M27×2 with an internal tapered surface, while the other end features imperial pipe threads. I searched online for a long time but couldn’t find any relevant standards. Does anyone among you know which standard is used?
This can be designed on one’s own; the standards serve only as references
The original poster should find some proper standard thread information and take a good look at it! A mature company like Nikki generally won’t use some weird and unusual threads for you!
Such joints are generally suitable for high temperature and high pressure conditions; my mechanical seal assistance system also features such a design
