High-pressure hydrostatic test plugs Grip-lock

High-pressure pipeline testing plugs incorporating proprietary Grip-lock and Posi-Seal holding mechanisms. Enable pressure testing of open-ended pipes up to ANSI Class 2500 without requiring welded end caps. Drastically reduces field welding costs, fabrication time, and post-weld NDT.

Proven Grip-lock and Posi-Seal mechanisms providing safe self-gripping.
Standard and tailored tool sizing spanning from 0.5 inch up to 36 inches.
Eliminates temporary weld-cap fabrication and subsequent cut-off operations.
Controlled gripper footprint preventing internal pipeline surface gouging.

Flange weld testers and internal joint tools FWT

Specialized FWT testing tools designed to hydrotest circumferential flange welds and pipe joints locally. The device isolates an annular chamber across the joint using dual high-pressure elastomer seals. Achieves immense water conservation and cuts turnaround downtime dramatically.

Localized hydrotesting isolating only the joint without full line flooding.
High-integrity radial elastomeric seals withstanding test pressures to 300 bar.
Minimizes overall testing time, de-watering procedures, and downtime delays.
Direct testing of weld-neck flanges and spool makeup joints in the field.

Configuration and engineering of iNPIPE pig launchers and receivers

When designing pipeline pigging stations for mainline oil and gas transmission systems, selecting iNPIPE Launchers and Receivers relies on line operating pressure, pipe steel grade, and the length of cleaning and inspection tools deployed.

The vessel features an enlarged barrel section accommodating long multi-module intelligent inspection pigs, bypass kicker piping for motive fluid flow, and lower drainage connections for debris washout.

The quick-opening closure integrates a heavy-duty locking ring and an engineered mechanical safety interlock that physically prevents opening while residual pressure remains inside the trap.

Stations are supplied complete with internal stainless guide trays, pig passage signallers, and hydraulic pig pushing equipment to facilitate safe tool loading.

Installation and calibration principles for iNPIPE 360° pig signallers

Flagship mechanical and electronic iNPIPE 360° series pig passage indicators mount on pressurized pipelines via welded thread-o-let or flanged nozzles.

The omnidirectional trigger mechanism rotates smoothly through a full 360-degree circle, ensuring positive actuation regardless of the angular orientation of the device relative to product flow.

During installation, trigger immersion depth into the pipe bore is fine-tuned with 5 to 12 mm clearance from the internal wall. An integrated hermetic SPDT or DPDT microswitch transmits telemetry pulses to supervisory plant DCS systems.

For monitoring magnetic scrapers on pipelines without hot tapping, CD52 non-intrusive sensor units strap directly to the pipe exterior using stainless band clamps.

Polyurethane pig selection based on pipeline bore and profile geometry

Selecting the optimal pipeline pig for batching, cleaning, or de-watering operations depends directly on line geometry, bend radii, and deposit hardness.

For pre-commissioning newly built pipelines, resilient open-cell and closed-cell foam pigs with densities of 80 to 120 kg/m³ swab debris and discharge test water efficiently.

In operational pipelines subject to diameter variations, PROTEUS series conical cup pigs negotiate internal bore restrictions reaching up to 25 percent without stalling or breaking fluid seal integrity.

Assembled bi-directional mandrel pigs fitted with polyurethane disc packages and circular steel brushes provide maximum scraping force against hard wax deposits.

Safe hydrostatic pipeline pressure testing using Grip-lock test plugs

iNPIPE Grip-lock and Posi-Seal hydrostatic testing plugs deliver secure temporary isolation of open-ended pipe spools during workshop and field hydrotests up to ANSI Class 2500 ratings.

As hydraulic test pressure rises, serrated Grip-lock gripping wedges bite into the internal pipe wall, transforming axial fluid thrust into solid radial anchoring.

The resilient Posi-Seal elastomer ring energises proportionally with increasing test pressure, completely stopping pressurized fluid leakage across the pipe boundary.

Following mandatory pressure holding and drainage, the holding mechanism releases smoothly via a central retracting bolt without causing gouging damage to pipe bevels.

Localized flange weld testing using high-pressure FWT tooling

During compressor station and terminal construction, qualifying individual butt welds and weld-neck flanges without filling the entire pipeline spool with water is achieved with iNPIPE FWT tools.

The testing device inserts into the pipe bore and clamps against the flange face, creating a narrow annular pressure cavity of 50 to 100 mm across the circumferential weld.

Hydrotesting with a compact volume of water at pressures up to 300 bar takes only minutes, saving substantial expense associated with subsequent pipeline drying.

The reusable FWT tool accommodates standard ASME B16.5 flange configurations and butt-welded piping spanning diameters from DN 50 to DN 900.

Internal pipeline debris mapping and profiling with PHOENIX modules

The PHOENIX intelligent pigging tool provides detailed assessment of internal pipeline condition, sediment mapping, and bore geometry ahead of baseline in-line inspection runs.

The sensor array aboard the PHOENIX platform scans the internal pipe circumference across 360 degrees, recording precise thickness values for wax layers, sand deposits, and mill scale.

An integrated high-definition video inspection camera illuminated by circular high-intensity LEDs captures crisp visual evidence of root penetration and surface corrosion.

The self-contained module operates from internal lithium battery packs and mounts on either rigid steel mandrels or flexible polyurethane foam pig bodies.
