¨ Temperatures up to 250°C
¨ Short lead times
¨ The lowest prices in the UK
¨ Designed and manufactured in the UK.
Application
The style P sight
glass has a plain spout cast in the body and is used to check for the presence
of a liquid where there is intermittent flow, partially filled lines or
entrained air. It can be used in vertical or horizontal lines. The integral
drip lip makes it ideal for leak detection.
Construction
The bodies are cast
in either carbon steel or 316 stainless steel.
The glass windows
are held in place by stainless steel covers and screws, and sealed with
PTFE gaskets, giving superior protection. For ease of maintenance the
glasses can be individually removed and replaced.
For standard applications
the indicator is fitted with toughened soda lime glass discs to BS3463
and rated to 16 bar. For steam and condensate
we recommend toughened borosilicate glass, while for alkaline liquids mica
discs can be used to protect the glass.
The sight glasses
can be supplied with screwed connections to NPT, BSP parallel or taper. The
standard flanges available are ANSI 150, ANSI 300 and PN16, though special flanges can
be supplied.
Options
Body - Primary Flowpoints can supply
sight glasses in special materials such as super duplex or low carbon steels.
Sight glasses conforming to NACE MR0175 can be produced. For particularly
corrosive applications the body can be lined with HALAR, ECTFE or PFA.
Glass - High pressure toughened
soda lime to BS3463 rated to 60 bar, toughened
borosilicate to BS3463 or DIN7080 rated up to 16 bar. The high pressure
range uses powder coated mild steel covers as standard, though stainless
steel covers are available..
Output -
A flow switch can be fitted to the indicator to give an alarm if the flow
moves above or below a preset value.
Quality
All flowpoints indicators
are manufactured to the highest standards.
The quality system
is independently audited by BSI and certified to ISO 9000. The indicators
are fully PED compliant and CE marked where required. TUV are our external
auditors for the Pressure Equipment Directive.
Full material traceability
is maintained, material certificates and pressure test certificates are
supplied on request.
