Application
The style T sight
glass has a plain straight through borosilicate glass tube with stainless
steel flanged ends 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.
Construction
The standard flanges
available are ANSI 150 and PN16 made from 316 stainless
steel whilst other flange specifications and materials can be supplied.
The flanges are held in place by stainless steel tie rods and fasteners
that give it a rigid construction. The seals are viton o rings giving superior
protection. For ease of maintenance the glasses can be individually removed
and replaced.
Options
Flanged Ends -
We can supply sight glasses in special materials such as duplex, super
duplex or low carbon steels. Materials can be supplied conforming to NACE
MR0175. For particularly corrosive applications the flanges can be lined
with HALAR, ECTFE or PFA.
Perspex Shield -
We can fit a perspex safety shield round the glass tube to protect against
accidental damage.
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 and material certificates and pressure test certificates
are supplied on request.
