Hybrid Cooling Enhances Compressor Station Operaton


Published:

The current shale gas boom in the United States can be likened in potential economic impact to the high tech boom of the late 1990s and even the recent rise in social networking technology — both being innovations in the development of previously overlooked assets.

Caterpillar Releases Valves, Seats For Pressure Pumping Customers

Caterpillar has released its Cat valves and seats for well stimulation pump fluid ends. Cat 4- and 5-series valves and seats are designed to maximize interchangeability across the Cat well stimulation fluid end line and be dimensionally compatible with industry standard fluid ends in the 2000 to 3000 hp (1491 to 2237 kW) range. Fluid end valves and seats are highly-consumed parts in well stimulation operations and, as a result, are frequently replaced. Historically, Caterpillar uses valves and seats obtained from alternate sources. Caterpillar’s new fluid end valves and seats provide decreased wear and extended life to pressure pumping customers, the company said. The material life of the fluid ends is extended by optimizing the geometry of the Cat valve and seat, increasing the contact area and improving the distribution of forces, resulting in reduced material fatigue, Cat said. The flow area is increased by balancing the pressure drop across the Cat valves, reducing flow restrictions and the potential for cavitation. Additionally, impact forces are reduced as the contact area between valve and seat has nearly doubled from previous designs. Caterpillar manufacturers a line of pressure pumps with maximum inputs ranging from 600 to 3000 bhp (447 to 2237 kW). The new valves and seats can be ordered from the global Cat dealer network.
