GENERAL
The HAM-LET Pipeline range of connectors is manufactured for typical applications in chemical and petrochemical processing plants, as well as oil, gas and power generation industries.
FEATURE
Sizes range from 1/16” to 2”.
Fittings are properly packaged with the exposed threads protected to ensure they are not damaged during delivery.
All pipe threads meet the requirements of ASME/ANSI B1.20.1 (1983) for tapered pipe threads (NPT).
Working pressures are calculated in accordance with Power Piping Code ANSI B 31.1, Refiner Piping Code ASME/ANSI B 31.3 and section VIII of ASME Boiler & Pressure Vessel Code.

INSTALLATION INSTRUCTIONS
To ensure a leak-tight seal, HAM-LET recommends the use of a pipe thread sealant on all NPT threads. The most effective sealing method is PTFE tape. Tape should be used only on male tapered pipe threads.
Do not use tape on flared, coned or tube fitting ends!
Clean both male and female tapered threads. Wrap tape in the direction of the male tapered thread spiral.
Note: Two wraps are suggested for stainless steel tapered pipe threads. Make sure tape does not overhang the first thread, as the tape might shred and enter the fluid system.
Cut off excess tape. The connection is now ready for proper makeup.
