SAFE SPLIT sleeve installations

摘要

Josh Wilson and Brandon Boyd, Mathey Dearman, USA, examine a new chain clamp that gets a grip on safety for pipeline split sleeve field installations. According to the Pipeline and Hazardous Materials Safety Administration (PHMSA), over 50% of the 2.5 million miles of pipelines currently in service across the US are at, or over, 50 years old. As you can imagine, the priority to inspect and maintain these transmission systems increases year over year. As more and more companies implement pipeline integrity management programmes, many strive to identify any opportunities to improve efficiency and safety wherever possible. When a potential defect or anomaly is identified by a pipeline inspection gauge (known as a 'pig'), a common repair method is to install a Type A or Type B welded steel repair sleeve.
