Determination Factors of MAWP at High Temperature Application 

To determine allowable working pressure at elevated temperature, multiply allowable working pressure and factors which are shown in the table.

Pipe End Thread Information 

The end connections with the lower pressure rating is the determining factor of pressure rating for the fittings with both UNILOK tube ends and pipe thread ends . 


Pressure Rating for Pipe End Thread 


Tapered Pipe Threads - NPT or ISO 7/1(BSPT)
Allowable pressure ratings for male and female threads are based on ASME B31.3 at ambient temperature.
ISO 228/1 Parallel Thread (BSPP)
The pressure ratings are at ambient temperature.

O-Seal Fittings 

Rated to 206 bar (3000 psig) for 316SS fittings up to 1 inch and 25mm 


Kinds of Pipe End Thread

NPT Pipe Thread
NPT (National Pipe Thread) is based on ANSI B1.20.1.

ISO 7/1 Tapered Pipe Thread
International Organization for Standard (ISO 7/1) Tapered (PT) Equivalent to BSPT (British Standard Pipe Taper Thread), DIN 2999, JIS B0203

    

ISO 228/1 Parallel Pipe Thread
International Organization for Standard (ISO 228/1) Parallel(PF) Equivalent to BSPP (British Standard Pipe Parallel Thread), DIN ISO228/1, JIS B0202 Gasket or O-ring is normally used to seal into the parallel female threaded components.

  

Features

Gaugeability

UNILOK tube fittings are produced with exact and tight tolerances. Without such close tolerances, proper interaction among the nut, ferrules, and body would not occur.


Corrosion Resistance

UNILOK ferrules have the strongest corrosion resistance due to our own special hardening process. 

This has been proven in various industrial areas over several decades.


Interchangeability

UNILOK tube fittings can be interchanged with tube fittings manufactured to international standards.


Less Torque and Anti-Distortion

When the nut is tightened, both ferrules are driven forward between the nut and the body. 

This axial movement doesn't transfer any torque from the fitting to the tubing when the original tubing's mechanical properties are maintained.
