摘要： An LNG sampling system is provided which includes a sampling probe. The sampling probe includes a backflow prevention check valve positioned within the probe adjacent the inlet end. The probe is inserted into a source of LNG to extract samples of LNG by providing a pressure differential between the probe piping system and the pressure of the LNG within the source. In the event the pressure in the piping system increases above a predetermined amount, the check valve will close preventing backflow of LNG from the sampling system back into the source.

摘要： A removable heat inducer may be used in either a heated regulator or a fluid heater. The removable heat inducer has various embodiments. In one embodiment, helical threads are formed on the outside surface of the inducer. The inducer expands when heated causing the crest of the threads to come into contact with the inside surface of a heating chamber to form a spiral fluid passageway which promotes better heat exchange between the fluid and the heating element. In a first alternative embodiment of the inducer, a series of walled partitions and slots are formed on the outside surface of the inducer, which likewise expand and contact the inside surface of the heating chamber to form a dead head flow passageway. Again, the purpose of the passageway is to promote efficient heat exchange. In a second alternative embodiment of the removable heat inducer, a plurality of rods are placed in the heating chamber to promote heat exchange. The spaces between the rods form passageways for the fluid. The removable heat inducer may be used in a heated regulator or a fluid heater.

摘要： A sampling cylinder for LNG (liquefied natural gas) is provided. The sampling cylinder includes a piston cylinder arrangement having opposite end members closing the chamber inside the cylinder. Various porting arrangements are provided for allowing fluid to be fed into a chamber inside the cylinder on opposite sides of a piston. A sample chamber is provided at one end member of the cylinder. The end member containing the sample chamber is also provided with a heat exchanger that may be connected to a source of coolant and preferably the LNG to be sampled to effect cooling of the end member at least partially prior to the sample chamber having a sample of LNG injected thereinto.

摘要： A removable automatic insertion device with segmented drainage shaft may be used to remove unwanted liquids from pipelines, tanks and other pressurized vessels. The insertion device inserts and withdraws the drainage shaft, one segment at a time into the pipeline or other pressurized vessel. A termination assembly is connected to the subsurface end of the drainage shaft and includes a normally closed drainage valve assembly. After insertion of the drainage shaft, the automatic insertion device is removed and a surface mounted discharge assembly is connected to the drainage shaft. To open the drainage valve assembly and commence drainage of unwanted liquids, pressurized fluid is injected through the discharge assembly, and a segmented hollow actuation tube to open the subsurface drainage valve assembly. Unwanted fluids then pass through the open drainage valve assembly, the drainage shaft to the surface mounted discharge assembly.

摘要： When sample collection cylinders get full, they need to be switched out with empty sample collection cylinders. The connection between the sample cylinder and a piping system is often a quick-connect which typically has a high pressure rating when closed and a lower pressure rating when opened. The bleeder valve of the present invention, when installed in the piping system between the quick-connect and the sample cylinder can be used to reduce the pressure in the system and the quick-connect to rated pressures before the quick-connect is opened. In an alternative embodiment intended for service with hazardous materials, the bleeder valve and seals are formed from resistant materials and the vent is connected to a flare or other suitable point of disposal.
