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.

Features, Codes and Standards

  • All Pipe End Plugs are designed to STATS engineering standards (based on international codes)
  • This facilitates 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
  • E-PEP covers pipes from 3" to 24"
  • Fail-safe design
  • Pipe End Plug through-port system allows filling / pressurisation and venting of test medium

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.

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.

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.

Features, Codes and Standards

  • All Pipe End Plugs are designed to STATS engineering standards (based on international codes)
  • This facilitates 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
  • Pipe sizes from ¾” to 42”
  • For sizes ¾” to 2” mechanical tools are used and fitted with securing clamps for added safety

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 ¾” to 42”, however for sizes ¾” to 2” mechanical tools are used and fitted with securing clamps for added safety.

Subsea Pipeline Plugging & Abandonment

For subsea abandonment, Pipe End Plugs can be operated by ROV. Despite being relatively simple tools, their installation in a subsea abandonment context carries risks, particularly the danger to divers from pressure fluctuations and the potential for flow into the pipe bore which could suck a diver inside.

Special requirements from clients, such as dewatering ports or designing them to double as lift and pull tools, can often be accommodated.

Local Everywhere

Instead of flying people and equipment all over the world, we've set up fully-functional bases in nine strategic locations. These bases enable us to employ local technicians, work with local manufacturers, and invest in local economies. They're a significant investment, but our regional bases are key to delivering the best possible service for our clients - and minimising the environmental impact of our work.
