The ONIS Quick Action Line Blind provides a safe, efficient, and easy-to-maintain solution for isolating pipelines during maintenance and inspection. With spreading technology and external seals, it reduces downtime, simplifies maintenance, and eliminates the need for complex disassembly or specialised tools.

Why positive isolation matters in pipeline safety

Isolating equipment for maintenance and inspection is crucial for ensuring pipeline safety and functionality. Positive isolation (or blinding activities) stops hazardous materials from entering a section of pipeline required to be shut down for maintenance, allowing workers to perform tasks safely while avoiding disruption to the rest of the pipeline system. 

Traditional line blinds often require shutdowns, disassembly, and specialised equipment to maintain—leading to costly delays. The ONIS Quick Action Line Blind offers a modern alternative that simplifies the process and enhances operational efficiency.

What sets the ONIS Quick Action Line Blind apart?

The key difference in ONIS technology lies in its design

Traditional Line Blinds

  • Rely on non-spreading mechanisms with internal components.
  • Internal seals are difficult to reach and replace.
  • Maintenance requires full pipeline shutdowns and disassembly.
  • Often involves cranes and heavy machinery.

ONIS Quick Action Line Blind

  • Uses spreading technology, eliminating internal release mechanisms.
  • Seals are external and easily accessible.
  • Maintenance can be performed without pipeline shutdowns.
  • No special tools or heavy equipment required.

This design reduces downtime, simplifies operation, and lowers costs for pipeline operators.

How to use the Quick Action Line Blind

Operation is straightforward and user-friendly:

  1. Actuation – Two forged half-bodies are actuated by a lever or hand wheel connected to a gearbox.
  2. Flange spreading – Synchronised eccentric shafts generate the spreading movement.
  3. Slide gate positioning – The slide gate moves into a full bore or blind position.
  4. Clamping – Reversing the lever or hand wheel locks the mechanism.

The clamping system is self-locking, resistant to overpressure and vibration, and factory-tested for reliability.

The equipment is factory-set and tested, eliminating the need for on-site adjustments after installation or operation.

Watch how it works

Simplified maintenance with external seals 

One of the biggest advantages of ONIS Quick Action Line Blinds is their simplified maintenance process:

  • Only four seals (two online, two offline).
  • All seals are located externally for easy access.
  • Seals can be replaced without pipeline shutdowns.
  • No cranes or heavy equipment required.
  • Typical replacement: once a year or when damaged.

This accessibility makes ONIS ideal for industries where extended shutdowns lead to high costs and production delays.

CRC Evans’ DATA360 platform is transforming pipeline construction projects with advanced digital data management for onshore and offshore infrastructure.

What is DATA360?

DATA360 is CRC Evans’ flagship digital platform, designed to streamline infrastructure and energy projects by providing end-to-end lifecycle data management. From pipe manufacturing to final installation—whether laid in the ditch onshore or submerged offshore—DATA360 creates a digital footprint for every pipe joint using a unique identifier. 

This innovation solves one of the pipeline industry’s biggest challenges – fragmented systems and siloed information.  

DATA360 delivers a true cradle-to-grave digital record by consolidating critical workflows such as welding, coating, NDT, material traceability, and AI-powered fitment analysis. 

Why digital data management matters in pipeline construction

Traditional pipeline projects often rely on multiple disconnected systems, slowing down compliance checks and increasing the risk of costly errors. DATA360 eliminates this by creating a cradle-to-grave digital record, allowing contractors, owner-operators, and inspection companies to: 

  • Improve compliance and traceability
  • Enhance efficiency and reduce downtime
  • Cut costs with streamlined workflows
  • Access real-time project data anytime, anywhere.

CRC Evans Vice President of Engineering and Technology Shailesh Radhakrishnan says: “Traditionally, collecting and analysing data from a construction project can take hours each day.

Case study: 9,000-joint welding project compliance streamlined with DATA360

In 2023-24, Van Oord used DATA360 as a data and joint ID monitoring system for an Exxon gas pipeline located offshore Guyana. The project consisted of over 9,000 joints and had strict compliance requirements.

To prevent pipeline failure, it was critical to keep the hardness of the material in contact with the medium (ID pipe and root pass) below 248 HV10. This meant the heat input must be 100 percent verified to maintain the hardness levels and stay within the welder performance qualifications (WPQ). 

DATA360 was used to: 

  • Monitor the end-to-end welding for all stations;
  • Track data for specific joints against unique joint IDs; and, 
  • Supply Exxon with hard copies of the data as proof of compliance. 

The system provided a log record for each joint as evidence that the completed welds were within the boundaries of the welding procedure specification (WPS) and thus fit for purpose from a mechanical point of view. 

Benefits for CRC Evans and Its clients

DATA360 not only supports clients but also drives internal efficiency at CRC Evans. 

At the Kintore facility in Scotland, engineers use DATA360 for:

  • Fast retrieval of welding data and reports
  • Real-time analysis for quality verification
  • Post-production insights to improve future projects

Kintore Senior Welding Engineer Melina Hemery says she finds DATA360 a powerful tool that saves her team considerable time on documentation, data capitalisation and problem solving. 

“It allows us to quickly retrieve welding data, available in the form of a customisable “as-run” report. These reports, obtained in record time, allow us to verify that all welding parameters are correct and therefore guarantee the quality of the welds.” 

Hemery says that she uses the system before, during, and after production: 

  • Before: by verifying our welding parameters during procedure development
  • During: to confirm the expected quality and provide the data to third parties and customers
  • After: to analyse data, improve procedures for specific applications, and use them on future projects.

For Kintore’s Senior R&D Lead, Stephen Cameron, DATA360 has transformed the way he approaches his research: “I can pull graphs from any weld that is in process or complete. It gives me a great visual aid to assess how the machines are performing. It lets me hone in on any potential issues before they arise, which ultimately leads to improving weld quality. 

“DATA360 has really made my life easier and is now a permanent tool on all equipment in our facility in Kintore,” says Cameron.

The Sypris Sig-Tech Intrusive Pig Signaler.
The Sypris Sig-Tech Intrusive Pig Signaler.

How the Sig-Tech Intrusive Pig Signaler works

Installed at predetermined intervals along the pipeline, the Sig-Tech intrusive pig signaler detects the movement of cast polyurethane pigs or spherical type pigs. A trigger mechanism extends into the pipeline through a welded boss fitting. When a pig passes, it activates the trigger, which sets off a signaling mechanism, confirming the pig’s position and supporting real-time operational decision-making.

This signal provides confirmation of the pig’s passage, helping operators verify pig locations, monitor run success, and identify any potential obstructions or failures in real-time.

Designed for flexibility and ease of use

The Sig-Tech is easy to install, with each boss fitting designed to the correct intrusion depth based on wall thickness requirements. A flanged mounting option is also available if required. The signaller can be installed and removed under operating pressure, acting in a similar way to a pressure and equalisation fitting completion plug. 

Once installed, the signaler requires no further calibration or adjustment – offering a plug-and-play solution. 

The 3705 PSI (Class 1500#) design is compatible with other leading brands, which makes it a flexible option for both newly constructed pipelines and system upgrades. In addition, using the appropriate tools and procedures, the signaller can be installed on live pipelines, avoiding the need for costly shutdowns. 

The Sig-Tech’s stainless steel NACE MR0175 compliant construction is weather and corrosion-resistant, ensuring durability and performance in extreme environments, including offshore and remote installations. 

The Sypris Sig-Tech can be removed and installed under pressure like a pressure and equalisation fitting completion plug.
