Mechanically
attached connector
system
Tube-Mac Piping Technologies is the manufacturer of Pyplok
®
connectors and swaging tools. Chris Peitchinis, the company’s
vice president global sales, outlined the benefits of using
Pyplok mechanically attached connectors, which reduce new
installation or maintenance repair costs.
Pyplok connectors are attached cold, in seconds, by swaging
the connector on the pipe or tube with a hydraulic handheld
tool. All the labour and associated costs of a conventional
welded connection are eliminated. No special skilled labour is
required. Actual swaging time is measured in seconds rather
than hours for a welded joint. No special hot work permits
or fire watch personnel are required. There are no leaks as
a result of stress fatigue cracks as seen in welds, no cost to
X-ray welds, and no cost to re-work welds.
The Pyplok system has been successfully used in a wide
variety of industries such as marine and offshore, steel
industry, oil and gas, and refinery. Applications range from
hydraulic oil, lubrication, fuel lines, steam trace, and other
fluids and gases. Pyplok is a solution for OD tube from ¼" to
2", metric tube from 6 to 90mm, and NPS pipe from ¼" to 3".
Due to the nature of the design, the connector is dependent on
outside diameter and the wall can be virtually any thickness.
Pyplok connectors are suitable for pressures up to 10,000 PSI
(690 bar) depending on the size and safety factor.
The three-step installation process is fast and simple after
cutting and de-burring the pipe or tube. Firstly, mark the
insertion depth on the pipe using the inspection/marking
gauge. Secondly, insert the pipe in the Pyplok connector,
position the tool over the connector and pressurise the tool to
swage the connector on to the pipe. Finally, quality-assure the
swage with the inspection/marking gauge.
The actual swage cycle time varies by size, but is typically from
10 to 30 seconds. Pyplok connectors have two elastomeric
O-ring seals at each end. The inner O-ring seal closes off all
the potential leak paths and the outer O-ring seal on the end
of the fitting acts as a back-up and an ‘environmental’ seal
to prevent sea water or other contaminants from entering
between the connector and the pipe. The connectors are
supplied in carbon steel with Cr (VI)-free plating, 316 stainless
steel, and copper nickel (CuNi) 70/30. Other materials are
available upon request, such as Duplex and Super Duplex
stainless steel. Pyplok conforms to standard end connections,
SAE, NPT, DIN and flange patterns in accordance with SAE
Code 61/ISO 6162-1, SAE Code 62/ISO 6162-2, ISO 6164
and ANSI Class. In addition to standard shapes such as tees,
45º and 90º elbows and reducers, custom connectors are
available.
