Hammer union pressure transmitter
Hammer union pressure transmitter definition
PM460 Hammer union pressure transmitter, also called hammer union pressure transducer which is made of high-strength, high-elasticity, corrosion-resistant stainless steel. It is a high-reliability, corrosion-resistant, high-long-term stability product specially designed for oil pressure testing of oil wells such as cobalt wells, cementing and fracturing vehicles.
Hammer union pressure transmitter design
The special structural design and strain isolation technology minimize the zero temperature drift of the transmitter due to the installation stress, and its long-term stability is also greatly improved. The pressure sensitive diaphragm and 1502, 2 inch spherical interface are integrated into one body, and the other components are processed by electron beam welding. The aspect ratio of the weld is unmatched by other welding processes. The whole instrument is integrated to ensure the hammer installation process. And high-intensity vibration during use and reliability under impact.
Hammer union pressure transmitter features
Components that come into contact with the pressure medium have excellent resistance to mechanical wear and corrosion from corrosive media such as H2S. The thick and shallow structure of the inner bore is effective to prevent blockage of the slurry and facilitate maintenance.
Hammer union pressure transmitters play a crucial role in ensuring safety on oil rigs. These transmitters are designed to fit Figure 1502 fittings and can withstand pressures of up to 15,000 PSI. They provide critical measurements during drilling and production operations, such as monitoring fluid levels and detecting leaks. To address customer challenges with competitor units, one company has introduced a fully welded body to prevent failures due to vibration, and tested the sensor’s shock resistance by repeatedly throwing it from a 30-foot drop until they could no longer break it. Field usability was also improved with a wider top access for easier cable connection, and large drain holes were added to eliminate water build-up around electrical connections. Additionally, some intrinsically safe hammer union transmitters are designed to withstand harsh environments, such as acidizing and choke & kill manifold operations.
