Lancaster Flow Automation offers compact, robust and reliable production chokes

The demands of modern-day oilfield production dictate that safety and reliability are paramount.

For more than 20 years, Lancaster Flow Automation has designed and manufactured a high-performance production choke, specifically engineered to process aggressive fluids composed of sand and other solid particles.

The engineering and manufacturing processes are characterised by the company’s commitment to innovation. The testing and research produce important information, but the company said the best feedback comes from the customers.

The advances in the production chokes reflect the need to accommodate increased operating pressures while delivering outstanding efficiency and reliability.

The company has designed a long list of important advances in its chokes. The company’s equipment, for example, requires extremely low operating torque; its stainless operating lever is only 7.5 inches long. There is no need for large hand wheels or additional personnel.

With a lightweight, low-powered actuator that can be installed while the choke is in service, automation is really simple. Any actuator type or brand is compatible, regardless of the trim type.

A tungsten carbide trim is standard, but the company offers multiple trim types with a single bonnet and body configuration. All seat assemblies use a non-threaded design that cannot be loosened from flow-induced vibration; which means there are no seat-to-body seal failures and body damage.

All the choke bodies are forged and have a reinforced inlet nozzle area and large body reservoirs that reduce internal erosion and extend the life span of the trim. The company’s superior manufacturing processes deliver improved corrosion resistance of standard stainless steel trim components and superior seal performance.

Lancaster has manufacturing facilities in Houston, Texas and Samarinda, Indonesia. And, they also have a service facility in Abu Dhabi, UAE.
