Abstract: Provided, in one aspect, is a groove measurement system. The groove measurement system, according to this aspect, includes a go measurement apparatus, the go measurement apparatus having first and second go gages protruding from one or more surfaces thereof, the first go gage having a go width (WG) generally equal to a minimum desirable groove width (WMI) of a desired groove, and the second go gage having a go depth (DG) generally equal to the minimum desirable groove depth (DMI). The groove measurement system, according to this aspect, additionally include a no-go measurement apparatus, the no-go measurement apparatus having first and second no-go gages protruding from one or more surfaces thereof, the first no-go gage having a no-go width (WNG) greater than the maximum desirable groove width (WMA), and the second no-go gage having a no-go depth (DNG) generally equal to the maximum desirable groove depth (DMA).

Abstract: An embodiment of a tool for clearing a deposit within a fluid flowline, including a body having a central axis, a first end, a second end opposite the first end, and a radially outer surface extending axially from the first end of the second end. In addition, the tool includes a first energy element coupled to the first end, and an electrode extending radially from the radially outer surface of the body. The first energy element and the electrodes are each configured to emit energy to dissipate the deposit in the fluid flowline.

Abstract: The disclosure provides an efficient design for a pressure rated oil field gate valve that meets the challenges of providing a quality product with minimal increase in price due to the design. It minimizes weight increase in the valve body over valves not meeting strict pressure specifications, due to strengthening ribs at strategic places without having to increase the overall body size as in commonplace in the industry. It provides redundancy of seals with minimal costs and no change in seat pockets over valves not capable of meeting the higher standards. It provides multiple shear points along a valve stem that can still allow a user to operate the valve from external to the valve bonnet. It further provides for additional sealing of the valve bonnet to the valve body by using elasticity in metal over long lengths to maintain a compression seal between the bonnet and the body.
