What does PHDAN stand for?
Physically Dangerous
What is the flare angle of a flare fitting?
37 degrees
What should you do if a flare fitting leaks?
Dismantle it and inspect
What are the two types of flare?
. Single flare
. Double flare
When would rigid tubing be used
In long straight runs and stationary applications
When would flexible hoses be used
Used in flexible parts or parts subjected to vibration
In rigid pipes what’s the psi of
High pressure lines
Medium pressure lines
Low pressure lines
Above 1500 psi (high)
Below 1500psi (medium)
Suction and return (low)
What’s the diameter of tubing measured in
1/8ths of an inch
What’s PHDAN stand for
Physically dangerous substance
What’s the benefit of double flair over single flair
Provides a smaller and better seal
How can an AN flair flitting be identified
37 degrees
It’s course thread
Blue and black
How can an AC flair fittings be distinguished
35 degree flair angle
Fine thread
Yellow or grey
How are flareless fittings sealed
Ball and bush principle
What’s an advantage of Harrison fittings over an MS fitting
Harrison fitting are vibration resistant
In flexible tubing What’s the pressure for
Lower pressure fittings
Medium pressure fittings
High pressure fittings
Low- up to 600 psi
Medium- up to 3000psi
High- more than 3000psi
What’s the most common material that the inner layer of flexible is made from and why
Teflon because it’s compatible with most fluids
What’s the negative of swaged
They can’t be removed or re used
Why are swivel fittings used
To elimnate tube bending
