Pipe End Plugs
Pipe End Plugs provide a fast and efficient method of installing temporary test caps on plain end pipe for hydrostatic leak and strength tests up to 350 bar / 5076 psi. Pipe End Plugs reduce time and material costs, minimise environmental impact and improve testing productivity and are robustly designed to sustain the rigours of the fabrication yard environment. STATS range of Pipe End Plugs cover two separate products with the I-PEP™ fitting the pipe internally and the patented E-PEP™ gripping the pipe externally.
E-PEP™ – External Pipe End Plugs
The E-PEP series of patented Pipe End Plugs are fitted to the pipe end and hydraulically actuated, gripping the pipe externally. The introduction of hydraulic set pressure activates a mechanical lock assembly that grips the outside diameter of the pipe whilst simultaneously energising an elastomeric seal in the internal diameter. This allows the pipework to be quickly and efficiently pressure tested with minimum preparation to the pipe end and no remedial work after the E-PEP is removed. A through-port allows the system to be filled and pressurised or vented through the E-PEP.
To remove the E-PEP from the pipe end, hydraulic pressure is applied to the unset circuit. Retracting the lock assembly and de-energising the seal, allowing the tool to be removed. The E-PEP range covers pipe sizes from 3” to 36” complementing the I-PEP range.
I-PEP™ – Internal Pipe End Plugs
The I-PEP series of Pipe End Plugs are inserted into the bore of the pipe and hydraulically actuated. These tools internally grip the pipe allowing hydrostatic pressure tests to be quickly and efficiently performed. The introduction of hydraulic set pressure activates a mechanical lock assembly that grips the internal diameter of the pipe whilst simultaneously energising an elastomeric seal. This allows the pipework to be quickly and efficiently pressure tested with minimum preparation required to the internal surface of the pipe and no remedial work after the I-PEP is removed. A through-port allows the system to be filled and pressurised or vented through the I-PEP. To remove the I-PEP from the pipe, hydraulic pressure is applied to the unset circuit, retracting the lock assembly and de-energising the seal allowing the tool to be removed.
Hydraulic I-PEPs cover pipe sizes from 30” to 42”, however for sizes ¾” to 2” mechanical tools are used and fitted with securing clamps for added safety.
All Pipe End Plugs are designed in accordance with STATS engineering standards (based on international codes) to facilitate testing in accordance with ASME B31.3 and similar piping codes. Sizes are based on standard pipe with interchangeable seals to cover ASME B36.10 and ASME B36.19 schedules.
- Reduced cost associated with welding and cutting end caps
- Saves time with faster completion of hydrostatic testing
- Sale or rental options available, complete with full ancillary equipment
- Simple, straight forward installation, installed and activated in a matter of minutes
- Test pressure applies differential pressure across the tool, keeping the locks and seals self-energised ensuring fail-safe operation
- Generous radial clearance to cope with typical internal obstructions such as weld beads, ovality, etc.
- Non-destructive, does not damage the interior/exterior wall of pipes or vessels
- High performance, large section, quality elastomer seals ensure a leak-tight seal and provide excellent radial expansion and relaxation properties, even after many operating cycles
- Through-port allows efficient fill or vent of the test medium
- Suitable for installation in horizontal, vertical and inclined piping
- Internal/external grip lock assembly applies even, linear and circumferential grip load around the host pipe, eliminating localised material deformity and localised stress fractures
