摘要： A freezeless wall hydrant is provided that has an elongated inlet pipe comprised of a hollow tube. The tube is connected to a valve and fitting assembly on its inner end for connection to a source of water under pressure. On the outer end, the tube is connected to an adjusting element with an outlet port that is associated with the valve and fitting assembly to open or close the tube to fluid flow and allow for fluid flow out of the tube when the valve is in the open position. The tube is comprised of a flexible material that enlarges in diameter in an area along its length when it is subjected to trapped fluid therein under high pressure so that the tube will not rupture. The tube returns to its normal diameter after the high fluid pressure therein is abated.

摘要： The present invention relates to an offshore installation including an oil/gas flowline umbilical installed between a platform—or a shore installation—and a sea bed based template and including an insulated electrical cable conductor connected in series with the steel oil/gas pipe to a power supply. The main features of the invention is that the far end interconnection between the cable conductor (or parallel cable conductors) and the pipe is grounded to seawater to provide a single point grounded system, such that all the current flows in the selected cable conductors, and the system has zero volts at the far end whereby no current is transmitted though the sea. The power supply is insulated from ground and the current is fed from the power supply through the pipe, and returns through the cable, whereby a voltage level of zero Volts is obtained at the far end where the system is grounded, and all the current is forced through the cable(s) and the pipe/flowline.

摘要： The invention is a round, flexible, hollow tubular insert to be affixed in a central position within pressurized sprinkler pipes, water pipes and water mains. The insert will be employed to prevent sprinkler pipe, water pipe and water main ruptures due to the water within the sprinkler pipe, water pipe or water main freezing. The insert is constructed of a thin-walled, flexible material that is capable of being deformed (e.g. compressed), thereby absorbing the expansion pressures exerted by the water in a frozen state (i.e., ice). The insert is constructed with guides to maintain a position in the center of sprinkler pipes, water pipes and water mains to absorb the radial freezing of water. By such absorption, the outer sprinkler pipe, water pipe or water main itself will not be over-pressurized, thereby avoiding the possibility of a rupture. Upon the thawing of the frozen water, the flexible, hollow, tubular insert will return to its original shape.

摘要： The present invention provides a flow control apparatus and method. In accordance with the present invention, the flow control apparatus comprises a thermostat that automatically actuates valve to enable water to flow through the valve when the temperature of the air or water is at or near the freezing temperature of water (32° F.). When the temperature of the air or water rises above freezing, the thermostat causes the valve to close, thereby preventing water from flowing through the valve. Therefore, when the apparatus is coupled to an end of a water conduit, such as a water spigot or hose, water is allowed to flow through the conduit when the air or water temperature is at or near freezing to prevent the conduit from bursting due to water freezing and expanding within the conduit.
摘要翻译：本发明提供了一种流量控制装置和方法。根据本发明，流量控制装置包括一个恒温器，当空气或水的温度处于或接近水的冷冻温度（32°F）时，自动启动阀门以使水能够流过阀门。当空气或水的温度升高到冰点以上时，恒温器会使阀关闭，从而防止水流过阀门。因此，当设备连接到诸如水插管或软管的水导管的端部时，当空气或水温处于或接近冷冻时允许水流过导管，以防止导管因为水冷冻并在管道内膨胀。

摘要： A heated flowline electrical isolation joint is disclosed for introducing current into a pipe-in-pipe system having an outer and an inner pipe. A hub presents a load flange having tension and compression load shoulders on its terminal end and connects to the inner pipe on its other end. An end flange presents an end flange load shoulder on one end and a high strength, highly electrically insulative first ring separates the compression load shoulder from the end flange load shoulder which engage therethrough in a load bearing relationship. A plurality of o-ring seals secure the compression load shoulder-to-first ring-to-end flange load shoulder interfaces. A retainer flange connects to the end flange on one end and to the outer piper on the other end, encircling the hub and presenting a retainer flange load shoulder. A second high strength, highly electrically insulative ring separates the tension load shoulder of the hub from the retainer flange load shoulder which engage therethrough in a load bearing relationship. A plurality of o-ring seals securing the tension load shoulder-to-second ring-to-retainer flange load shoulder interfaces. An electrical feedthrough tubes receives an electrical penetrator which reaches through the retainer flange to electrical connection with the hub. An electrically insulative material in the annulus between the hub and the retainer flange and between the electrical penetrator and the electrical feedthrough tube secures electrical isolation across non-load bearing areas.
