STATS comprehensive Tecno Plug™ range provides fail-safe double block and bleed isolation tools for high pressure operations. These dual seal isolation plugs are available for remote, tethered, piggable or manual deployment and operation.
The dual seal configuration of the Tecno Plug™ provides an annulus void which can be pressure tested to verify both seals are leak tight before maintenance work is carried out, both seals are leak tested at 110% of the maximum potential isolation pressure. Once the seal integrity has been proved the annulus is then vented to ambient to create a zero energy zone, providing effective double block and bleed isolation. The large section elastomer seals are highly compatible with poor pipe surfaces and are customised to suit corrosion or ovality issues ensuring a leak tight seal even in ageing assets. A through-port is provided for downstream pressure monitoring or pressure application as required.
Tecno Plug™ - Process & Pipeline Isolation
© STATS GROUP
The Tecno Plug™ fail-safe design uses differential pressure acting on the tool to energise the locks and seals, this is referred to as self-energisation. When the isolation plug is self-energised the isolation is maintained independent of the control system, it is however backed up by the hydraulic control system which maintains the isolation when the differential pressure is below the self-energisation threshold. Once the Tecno Plug™ is activated the hydraulic circuits are locked in by pilot operated check valves and manual isolation valves (tether controlled) or fail-safe solenoid valves (remote controlled). The Taper lock-ring provides twice the required lock contact area giving 100% contingency. In the event that the hydraulic control system is compromised, the tool actuation mechanism will unset when differential pressure is equalised. This feature ensures pipeline integrity is maintained and the Tecno Plug™ is always recoverable upon job completion.
The remotely operated Tecno Plug™ system is a piggable, remote controlled, tetherless isolation tool. The remote control system provides a high degree of flexibility and eliminates the need for tethers or specially modified pig-trap doors. Through-wall communication is achieved using an extremely low frequency (ELF) radio control system for reliable tracking and accurate positioning of the Tecno Plug™. An onboard hydraulic power pack provides the necessary actuation and control functions for the tool. The remote control module is ATEX rated and provides a robust system for safety critical activities, undertaken a rigorous validation programme.

BISEP™ - Pipeline Intervention & Isolation
Pipeline intervention and isolation can be achieved using STATS patented BISEP™. The BISEP™ range provides double block and bleed isolation deployed through a single full bore branch or hot tap penetration.
This high integrity isolation is provided by a spherical dual seal plug which is deployed from a pressure competent launcher through an isolation valve and rotated towards the flow of pressure to be isolated.
The spherical head houses twin compression seals and provides a facility to bleed and monitor the intermediate annulus creating a zero energy zone. The seal annulus port proves and monitors the seal integrity before and during intervention work. The BISEP™ head utilises the same compression seal technology as our Tecno Plug™ isolation tools.
The seals are activated by a hydraulic cylinder inside the plug which compresses the seals. The resultant radial expansion pushes the seals out to seal against the pipe bore. Further application of hydraulic pressure generates a rubber pressure in the seal elements which allows the annulus between the seals to be pressure tested. Line pressure acting against the tool pressure head maintains seal pressure creating a fail-safe feature providing actuation independent of the hydraulic system. The ejection load resistance is provided by the tool’s deployment head.
Once the BISEP™ is deployed and set in position the pipeline or valve maintenance / repair can take place safely and efficiently.

Pipe End Plugs - Hydrostatic Test
Operator Benefits
Simple, straight forward installation, installed and activated in a matter of minutesTest pressure applies differential pressure across the tool keeping the locks and seals self-energised ensuring fail-safe operationGenerous radial clearance to cope with typical internal obstructions such as weld beads, ovality, etcNon-destructive, does not damage the interior / exterior wall of pipes or vesselsInternal / external grip lock assembly applies even linear and circumferential grip load around the host pipe, eliminating localised material deformity and localised stress fracturesHigh performance, large section, quality elastomer seals ensure a leak tight seal and provide excellent radial expansion and relaxation properties, even after many operating cyclesThrough-port allows efficient fill or vent of the test mediumRobust construction ensures years of trouble free operation even in the harshest environmentsSuitable for installation in horizontal, vertical and inclined piping
Key Features
Pipe End Plugs are used primarily to cap open ended pipe, pipe spools or piping systems to facilitate hydrostatic leak and strength tests. Pipe End Plugs reduce time and costs compared to traditional methods of welding end caps to the pipe spool. 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.
Reduce cost associated with welding / cutting end caps during construction and fabrication activitiesSaves time with faster completion of hydrostatic testing during construction and fabrication activitiesSale or rental options available complete with full ancillary equipmentFully certified client training provided by highly trained STATS personnel to support Pipe End Plug hire
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.

E-PEP™ (External Pipe End Plug)
STATS GROUPProcess & Pipeline Integrity Solutions
© STATS GROUPUK-GRA-REF-003
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 OD of the pipe whilst simultaneously energising an elastomeric seal in the ID. 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. This retracts the lock assembly and de-energises the seal, allowing the tool to be removed. The E-PEP™ range covers pipe sizes from 3” to 24” and compliments the I-PEP™ range but with the advantage of not being limited to nominal pipe sizes as the selection of tool is based on the internal diameter of the pipe being tested.

4” Mechanical Coupling
STATS LC series of mechanical Connectors and Couplings are designed for the maintenance and modification of petroleum production and process facilities. This reliable and cost effective mechanical connection method is ideal where welded or hot-work options may be undesirable. The slipover design and mechanical locking assembly can enable a flanged connection to be installed on a straight pipe stub without the need for hot-work or specialised tools and equipment.
The Connectors and Couplings are configured with a dual seal assembly that enables the Connection integrity to be verified via the 300# seal verification ports at time of installation. Double block and bleed valves can be fitted to the seal verification ports to allow monitoring of integrity once installed. The seal configuration and material selection is designed to provide a reliable seal on the pipe surface following a relatively simple field preparation procedure.
The Connector and Coupling assembly and components are designed in accordance with API 6H requirements, which are verified in accordance with ASME B31.3 and may be CE marked under the Pressure Equipment Directive (PED 97/23/EC). They are designed to fit standard pipe specification (ASME B36.10 & B36.19, API 5L, etc) and fire tested to API 6 FA.
Bespoke design and manufacture of weldless connections for non-standard pipe sizes or configurations are routinely undertaken.
Specification
STATS comprehensive range of ancillary equipment and on-site machining services are available on a rental basis to support our range of Couplings and Connectors. We can also supply competent Field Technicians to provide operators a full turnkey package, delivering operators a first class maintenance solution for their assets.

Mechanical ConnectorsThe LC series of mechanical Connectors are designed to slip over a prepared pipe stub to provide a RF or RTJ flange connection. Once the lock and seal assemblies have been set, seal testing through the integral ASME 300# flanged outlet is undertaken to verify integrity. Correct fitting and assembly of the Connector can be easily verified visually, without requirement for special tools or equipment.
The Connector assembly and components are designed in accordance with API 6H, with design strength verified in accordance with ASME B31.3 and other codes (ASME B31.4, B31.8, ASME VIII, etc). CE marking under the Pressure Equipment Directive (PED 97/23/EC) may be applied, where applicable. Connectors are designed to fit standard pipe specification and are fire tested to API 6 FA.

Pipeline Repair Clamps
Pressure Containment Clamps have been developed for process piping repair on oil and gas pipelines and process facilities. Installation can be undertaken with minimal disruption to the pipework or operation of the system to which they are fitted. The Pressure Containment Clamps are designed to be installed on damaged or leaking pipework, encapsulating the defect within the clamp body and regaining pressure integrity through mechanical seals engaging on the sound parent pipe. The clamps are routinely fitted to overcome defects in pipe sections. Designed for simple installation, the clamps can be modified or redesigned to suit specific installation requirements. Fitting and testing pressure containment clamps is generally completed as a service by skilled STATS Technicians, however client training can be providing.

Structural Repair ClampStructural Repair Clamps provide pressure containment and, where grout filled, radial support to the pipe. Where a Pressure Containment Clamp is fitted with taper locks it becomes a Structural Clamp to provide axial restraint. The locks are configured as opposing sets which grip the pipe on either side of the defect. The locks are designed to transfer the full axial load of the pipe to the clamp body so allowing the clamp to withstand full pipeline separation loads.
Operator BenefitsRepair clamps maintain integrity and restore pipeline’s maximum allowable operating pressure (MAOP) capacityManufactured to suit specific pipe specificationRepair clamp provides equivalent or greater strength than the host pipeworkRobust construction and coating provide protection in a range of hostile operating environmentsCoating can be supplied to client specification

Hot & Cold Tapping Services
Key FeaturesContinuous system operation - shutdown and service interruptions avoidedHot Taps performed on a variety of piping and vessel materials and mediumsNo pipe content released to the atmosphereNo cutting, realignment and re-welding of pipeline sectionsPlanning and coordination costs reduced Increased worker safety
Once Hot Tapping is complete STATS can provide a verified double block and bleed isolation through a single penetration. The BISEP™ with dual compression seals and annular bleed provides a high integrity dual seal isolation allowing repair or modification work to safely take place. This single entry point isolation technique significantly reduces operator costs and timescales.
STATS Hot and Cold Tapping services allow a branch connection to be made into piping or vessels while the system remains live and under working pressure. This allows continuous system operations and avoids unplanned shutdowns or service interruptions.
STATS provide a safe and cost effective solution to allow efficient tie-ins for repair or modification purposes while under full operating conditions, therefore reducing plant downtime. STATS provide a full range of ‘industry best in class’ equipment and can provide a turnkey packaged approach from clamp or tee installation through to isolation of line content, inclusive of slab valve and completion flange provision. STATS will undertake system engineering analysis and project engineering as part of this service. A comprehensive service package is available to support Hot Tapping operations from ½” to 36” with alternative sizes available upon request.

On-Site Machining ServicesIn hazardous environments where the potential for fire or explosion exists or when greater precision is desired, STATS Cold Cutting & bevelling service replaces traditional methods such as torches, reed cutters, and grinders. Fully preparing the pipe end for welding with greater accuracy and a higher level of safety, field cuts are performed quickly and effectively often without the requirement for hot work permits.
STATS offer portable clamshell lathes designed for on-site precision severing, severing / beveling, and severing / double beveling.
The aluminum frame is a split ring assembly capable of being disassembled to be installed around in-line piping. The frame has bearing mountings for the rotating head, a drive motor mount, locator pads for mounting to the pipe, and a gear cover. Our low clearance clamshells are designed to fit into tight working areas as well as minimise machine weight. These clamshells are lightweight, but retain rigidity during operation.
Key FeaturesSizes ranging from 4” up to 40”Counterbore ModuleCompressed Air or Hydraulic Drive In-Line or Right Angle DriveLocator Pads for Extended RangeReduced Axial Clearance with special tooling
These lathes simultaneously sever and bevel as they cut. Tool bits are automatically fed radially into the work piece with each rotation of the lathe, which assures precise machining. The machines can be fitted with single point beveling tool boxes for heavy wall pipe. The split frame design enables easy setup on in-line piping, elbows, tees, valves, nozzles and flanges.
