Oliver Twinsafe is to supply double block and bleed pipeline valves for use on Monoethylene glycol (MEG) injection pump systems. MEG is a widely used hydrate inhibitor designed to reduce the risk of hydrate formation in pipelines that could cause blockages.

The order includes a batch of 2 1/16” API 6A 5000psi double block and bleed valves in A182 F55 super duplex material that have been dynamically tested to meet the requirements of API 6A PSL level 3. In addition, the valve designs were pre-qualified to API 6A PR2 Appendix F, which involves multiple cycle testing at low, ambient and high temperature with zero leakage allowed across the valve seats throughout these cycles.

A number of Oliver instrumentation valves have also been ordered, taking the total number of valves supplied for this offshore project overall to over 300 with more valves in the pipeline.
