Badger Meter valves meet tough demands in deep water oilfields

The Badger Meter Company, represented in the UK by Pump Engineering, was recently challenged to manufacture 1" valves which could handle ethylene glycol at flows up to 2 lit/min at 700 bar.

These valves were successfully deployed in deep water oilfields in the Eastern Gulf of Mexico where pressures are relatively high and temperatures relatively low and therefore the risk of hydrates forming is high.

To eliminate the potential problem of hydrates forming in flowlines at these depths and pressures, chemical additives, such as methanol or mono ethylene glycol, are injected into the well-stream. These additives act as anti-freeze and are effective in preventing hydrates from forming and therefore play a key role in helping to keep flowlines open.

Additive and injection applications are ideal for these valves as they are suited to both low pressure and high pressure duties. The Badger range includes models ranging in size from ¼" up to 2", capable of operating in temperatures from -270º up to +800ºC, with CV's from 0.000018 to 2.5 and rangeability from 50:1 to 15:1. They can be supplied as standard in 316 stainless steel or Stellite trims although alternative materials such as Monel, Hastelloy B& C, titanium and zirconium, can also be specified.
