Apparatus and methods for determining operational health of a pump. An example method may include commencing operation of a processing device to monitor operational health of a pump for pumping a fluid at a wellsite, wherein the pump may be a reciprocating pump. During pumping operations of the pump, the processing device may receive pressure measurements of the fluid at a fluid inlet manifold and/or a fluid outlet manifold of the pump, receive position measurements of fluid displacing members of the pump, detect irregular pressure measurements based on the received pressure measurements, determine operational phase of the pump based on the received position measurements, and determine which of fluid inlet and outlet valves of the pump is leaking based on operational phase during which the irregular pressure measurements are detected.

The invention relates to pipelines and equipment useful in nuclear power plants, heat power engineering, manufacturing engineering, petrochemistry, water supply, chemical and aerospace industries, and other fields. The invention relates to a pipe heat insulation casing consisted of metal elements and assembly method ensuring reliable electrical insulation of all elements. The connection of the metal elements is with lapping, the elements are with openings in the lapping area where the electrically-insulating spacers are set made of resilient, elastic-plastic, plastic, fully viscous or partially solidified material ensuring electrical insulation between the adjacent elements. The electrically-insulating spacers are applied to the lapping areas of the metal elements to fill the openings of the lapping areas thus arranging reliable pin connections between the spacer and adjacent casing elements. Multiple pin connections ensure fixation of the adjacent metal elements without any failure to electrical insulation of each other.

A gas leak detection system that combines sensor units having an array of sensors that detect natural gas and the volatile organic compounds and variable atmospheric conditions that confound existing gas leak detection methods, a specially designed sensor housing that limits the variability of those atmospheric conditions, and a machine learning-enabled process that uses the wide array of sensor data to differentiate between natural gas leaks and other confounding factors. Multiple low-cost sensor units can be used to monitor gas concentrations at multiple locations across a site (e.g., a well pad or other oil or natural gas facility), enabling the gas leak detection system to model gas leak emission rates in two- or three-dimensional space to reveal the most likely origin of the gas leak.
