Air Springs Supply presents a
range of rapidly deployed inflatable elastomer stoppers that offer pipeline
engineering and maintenance staff a secure way to conduct sealing and testing
operations without cutting throughput.
The need to cut throughput for
the duration of the maintenance work is a frequent problem faced by operators when
sealing and testing operations are carried out within pipelines. More downtime
can be caused by the need to transport and install solid mechanical barriers
with bracing to ensure safety during maintenance.
Pronal ORJT and ORJ inflatable
elastomer stoppers supplied by Air Springs Supply offer a cost-effective
solution for bypassing common pipeline testing problems.
Pronal ORJT inflatable elastomer
stoppers feature bypasses that fulfil two important roles: Liquid and gas contents
can continue to flow during the course of the maintenance work, with the
bypasses in each stopper connected by a conduit feeding through the secure void
created between the two stoppers. Alternatively, the bypasses can be used to
introduce pressurised liquid or gases into the void created between the stoppers,
providing a testing media to detect leakage.
ORJ stoppers are designed for
applications that don’t require bypasses but can be rapidly deployed, easily
transported and widely applied in remote, temporary and permanent industrial
situations, similar to the ORJT models. The ORJ stoppers are suitable for all
types of pipelines including concrete, cast iron, steel, stainless steel and
PVC.
Each stopper size can fit
several pipe diameters in the 45-1200mm range. Featuring flexible and strong
vulcanised construction that moulds into the inside circumference of pipelines
as the stoppers are pressurised, Pronal ORJT and ORJ models provide complete
tightness and high safety thanks to large contact areas and circumferential
rings.
Air Springs Supply National
Marketing Manager Mr James Maslin explains that the Pronal ORJT and ORJ stoppers
are extremely strong and durable in service, being hot vulcanised in a mould to
give excellent service life. In addition to providing advantages such as simplicity,
portability and reuse, the stoppers also eliminate the need for maintenance
staff to carry huge amounts of gear on-site. The stoppers are easy to transport
around plants as well as remote locations, where they can be used repeatedly.
Mr Maslin adds that the stoppers
are an ideal method to achieve compliance in a cost-effective and efficient
manner.
Pronal ORJT and ORJ stoppers are
part of a broader range of Pronal maintenance and spill prevention stoppers
available from Air Springs Supply in stock sizes to fit pipelines up to 2115mm
inside diameter, along with custom-produced models for pipelines over 3000mm ID.
