Terminology
Te
rminol
ogy
pierce-pressure mode (low-pressure mode)
Water that is at a reduced pressure that is used to make a hole in the material to be cut; using a lower pressure
prevents brittle materials from cracking
pipe
A rigid tube that carries low-pressure fluid
psi
Pound-force per square inch is a unit of pressure; 1 psi equals 0.07 bar or 7 kPa or 6,894 N ∙ m
2
static seal
The high-pressure seal at the output end of the high-pressure cylinder; this seal does not touch the plunger (see
dynamic seal)
system integrator
An integrator of waterjet cutting systems that include Hypertherm products that are sold directly to end users
reverse osmosis
A method for treating water by forcing it through a semipermeable membrane to remove impurities that can damage
high-pressure parts
SAE
SAE International is a professional association of engineers and technical experts that coordinates the development
of technical standards based on best practices in the aerospace, commercial vehicle, and automotive engineering;
SAE Code 61 fittings are designed for 207-bar or 20,684-kPa (3000-psi) applications; SAE Code 62 fittings are
designed for 414-bar or 41,369-kPa (6,000-psi) applications
tubing
A rigid tube that carries high-pressure fluid
valve
A device used to control the rate of flow in a pipe or a tube
