PIPELINE connecting technology delivered by Swagelining Limited is to bring increased benefits to operators after being proven to withstand significantly higher pressures during exploration and production activity. The company has announced that patented WeldLink ® fittings are effective in pressure applications of up to 410 bar. A recent hydrotest proves that this technology can now be used in even higher pressure applications throughout the oil and gas industry. Previously proven to be effective for use in up to 344 bar pressure, the 24-hour hydrotest saw a Swagelined 14" water injection pipeline, joined using the WeldLink connector, subjected to hydrostatic pressure of 410 bar. The results demonstrated that the WeldLink joint lost no pressure during the test and provided a complete water-tight seal. Steven Barnes, managing director of Swagelining Limited, commented, “We Mr Barnes continued: “Swagelining Limited’s Integrated Lining System has extensive industry credibility. As well as being at the heart of one of the world’s largest onshore lined water injection systems – a 55km x 24" onshore pipeline in Congo – Swagelining and WeldLink connectors are currently being used in the construction of the world’s deepest lined riser in offshore West Africa. This project, elements of which are currently being constructed at sites in Scotland and Holland, involves the lining of over 90 No 14" x 24m long spools, shipped for final installation by J-Lay vessel in 2,000m of water.” Swagelining Limited – UK Email: enquiries@swagelining.com Website: www.swagelining.com Opening up higher pressure markets have an increasing number of clients using our patented Swagelining technology to line subsea and onshore pipelines as an efficient and cost effective method of corrosion prevention. Proof that the connector technology along with the liner can withstand up to 410 bar pressure opens up new markets for our unique technology.” Originally developed for use in subsea pipelines, the WeldLink connector is a cornerstone product in Swagelining Limited’s Integrated Lining System – a concept which brings together liner design, material selection, project management, insertion technology, supply of connectors and terminations, and venting technology. WeldLink enables polymer lined carbon steel pipelines to be fully welded. This allows the pipeline system to operate at high pressures without the risk of leakage from flanges. The connector system has been in use in high pressure water injection pipelines systems for over 15 years.
