Valves are usually connected to pipes in various ways such as threaded, flanged, welded, clamped, and ferrule wafer. So, how should one choose when using and selecting them? What are the connection methods between valves and pipes? 1. Threaded connection: Threaded connection is a form where the ends of the valve are processed into internal or external threads to connect with the

On August 5th, with the successful completion of a horizontal well at the Guping 41-52 well site, the number of wells in the Changqing Heshui Oilfield's tight oil block-level horizontal well three-dimensional development area exceeded 650, making it the largest such development area in China. Since its development, the area has produced over 5 million tons of oil, with a cumulativ

As of now, the Tuha Oilfield has completed 46 various plans for capacity construction and other aspects this year, with the design compliance rate reaching 100% and the effectiveness rate of measures reaching 98%. This has effectively saved drilling and fracturing costs, and the supporting and guaranteeing role of engineering technology has become more prominent. As the oilfield

It is closely related to people's lives. Among them, various valve products with different functions have achieved a more secure and efficient good performance in actual use. Especially, fundamentally strengthening and improving water source management and usage has made water control valve products more diverse in features. Among them, effectively managing and improving management effic

On July 7th, the author learned that in the first half of this year, the commercial volume of coalbed methane in Huabei Oilfield increased by 45 million cubic meters compared with the same period last year. Huabei Oilfield has been committed to treating the coalbed methane business as an important growth pole for building a comprehensive energy company with a production capacity

Pneumatic control valves use compressed air as the power source, a cylinder as the actuator, and drive the valve with the help of valve positioners, converters and other accessories to achieve on-off or proportional regulation. They accept control signals from industrial automation control systems to complete the regulation of various process parameters such as flow, pressure and tempera

On May 21st, in the centralized control room of the refining area of Lanzhou Petrochemical, the internal line operators of the 5 million tons/year atmospheric and vacuum distillation unit were carefully comparing the quality inspection and analysis results. By swiping the mouse at the control points on the screen, they adjusted the external release volume of the atmospheric line a

If you do not carefully check the usage condition and performance specifications of the wafer-type electric butterfly valve before installation, the wafer-type electric butterfly valve may have the following common faults: the valve cannot be reversed or the reversing action is slow, gas leakage, and the electromagnetic pilot valve is faulty, etc. (1) The inability or slow reversing act
