only be properly installed with hydraulic crimping equipment.
NOZZLES
1. Read General Safety
section.
2.
Nozzle flow ratings must be compatible with pump discharge and
pump pressure rating. (See Nozzle Flow Rating Chart on page 25.)
3. Use only nozzles with a manufacturer’s pressure rating of at least
the operating pressure or a burst rating or no less than 3.0 times the
desired operating pressure.
4.
Prior to installation, make sure the nozzle has no clogged orifices.
5.
Apply 3 - 4 wraps of Teflon tape to male connection threads on the
nozzle. Apply anti-seize compound over the sealant tape for additional
protection against galling in connection threads. Wrench connection 1
1/2 - 2 turns past hand tight. A minimal thread engagement of four (4)
threads should exist on all Jetstream NPT pipe connections.
6.
Use wrench flats (when available) or a properly
adjusted smooth jaw plier wrench (JS PN 64119) to tighten nozzle. Avoid
using pipe wrench as wrench marks will cause nozzles to crack and fail.
7.
Blocked orifice(s) can cause excessive system pressure and failure.
If orifice(s) appear clogged or partially blocked with dirt or debris,
remove nozzle from J-Force and clean immediately.
8.
Remove nozzle from service if:
A. Nozzle is split or damaged;
B. Nozzle sidewall is worn by more than 25% at any point;
C. Nozzle’s ability to hold pressure is questionable
D. Threads are missing or damaged
FLEXIBLE TUBE CLEANING LANCES
1. Read General Safety
section and Nozzle Safety Warnings prior to
connecting flex lances.
2. Do not
use a flex lance with a burst rating less than 2.25 times
the pressure at which it will operate. 10,000 psi operating pressure
flex lances
must
have a
minimum
22,000 psi burst rating. 8,000 psi
operating pressure flex lances
must
have a
minimum
18,000 psi burst
rating.
