Description

COMPOSITE PULSATION DAMPENER
TECHNICAL FIELD
[0001] The present application relates generally to pulsation dampeners and, more specifically, to pulsation dampeners constructed of metallic and non-metallic materials.
BACKGROUND
[0002] Pulsation dampeners are used with cyclic hydraulic (e.g., reciprocating pump) systems circulating fluids to reduce the fluid pressure peaks that would otherwise accelerate deterioration of the system, the system' s fluid end expendable parts, and equipment upstream or downstream from the system with each subsequent pulsation. Failure to control pressure peaks inevitably affects the operating performance and operational life of a reciprocating pump in many types of applications, including drilling, well service, oil field service, operation of industrial equipment, and mining.
[0003] Pulsation dampeners are typically manufactured from steel or other metals or metal alloys due to the combination of the large vessel sizes (outer diameters greater than 20 inches) and high pressures that must be contained (on the order 10,000 pounds per square inch or "psi") . However, the use of steel or similar metals makes the pulsation dampeners extremely heavy, and thus cumbersome to mount or dismount on site for installation, maintenance, or replacement. Particularly in remote locations, equipment necessary to lift a pulsation dampener into or out of place is not always convenient to obtain or operate.
[0004] There is, therefore, a need in the art for an improved pump dampener that may be handled with greater ease. SUMMARY
[0005] A pulsation control device is constructed at least partially of a composite carbon (and/or other fibers) /epoxy exostructure having an oblong cylindrical or spheroidal shape, optionally with metallic portions or reinforcements, together with a non-metallic (plastic, e.g., HDPE, polymer) non-load sharing liner and metallic port nozzles consisting of integral dome and piping flanges . A pressure drop tube preferably extends from an opening through an exterior wall of the body into an interior space within the body. Alternatively, a different pressure drop device such as an orifice plate of one or more materials may be mounted against the outlet nozzle exterior to the body.

DETAILED DESCRIPTION
[0014] FIGURES 1 through 6, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged pump discharge dampener that controls or partially controls pulsation amplitudes.
[0015] FIGURE 1 is an external side view of a composite pulsation dampener according to an exemplary embodiment of the present disclosure. Pulsation dampener 100 has an intake 101 for receiving pumped fluids and an outlet 102 for discharging pump fluids under pressure. In use, the intake 101 and outlet 102 may be substantially interchangeable. The intake 101 and outlet 102 are formed from metallic port nozzles consisting of integral dome and piping flanges, as illustrated in FIGURE 1. Dome-shaped end caps 103 and 104 support the intake 101 and outlet 102 and are separated by a cylindrical central portion 105 of the body of the pulsation dampener 100.
[0016] Pulsation dampener 100 is constructed at least partially of a composite material (with possibly some metallic infrastructure or reinforcement) , including a carbon (and/or other fibers) /epoxy exostructure with a liner. For example, the liner may be formed of a polymer material. The composite pulsation dampener 100 depicted has a generally oblong planform with elliptical corners, curved (cylindrical) exterior walls and rounded or hemispherical (dome-shaped) ends each including an inlet into or an outlet from the interior space within. Alternative embodiments may use a spheroidal shape, without the elongated central cylinger. Not depicted in FIGURE 1 are vent and drain connections, lifting lugs, a support for mounting, inlet and outlet flange connections, the pressure drop assembly, and a nameplate, which those skilled in the art will recognize are conventionally part of a pulsation dampener.
[0017] The use of a composite carbon/epoxy material, optionally together with metal, in the construction of a pulsation dampener is unique, and without precedent for the extremely high pressures (in the range of 10,000 psig) that must be contained by the composite pulsation dampener 100 in combination with the large outer diameter (greater than 20 inches) of the body of the composite pulsation dampener 100 necessary for use in drilling operations. Of course, the system disclosed may be employed with much lower pressures, on the order of 5,000 to 7,500 psig, or much higher pressures, on the order of 15,000 to 25,000 as examples. In addition, the composite pulsation dampener 100 is an American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) Section X (Fiber-Reinforced Plastic Pressure Vessels) Appendix 8 Class III, Type IV rated and stamped composite vessel in terms of operating pressure and outer diameter combination.
[0018] The proposed structure also provides improved corrosion resistance to pumped fluids and in maritime environments.
[0019] The composite pulsation dampener 100 enjoys a weight savings of around 75-80% as compared to metallic pulsation dampeners for a specified set of operating pressure and volume capacity parameters, and will therefore benefit from lower handling and transportation costs. As compared to the weight of a completely metallic vessel, the composite pulsation dampener 100 reduces foundation loads, shaking forces, rolling and pitching forces on flotation vessels.
[0020] The composite pulsation dampener 100 also enjoys better corrosion resistance, and provides better protection from erosion due to the polymer liner. Moreover, composite materials have better acoustic and vibration dampening properties as compared to steel due to high co-efficient of damping and higher specific stiffness, improving the operating performance of the pulsation dampener 100 over a metallic counterpart.
[0021] The composite material also provides low thermal expansion. The low number of joints and low part count provides better reliability to the composite pulsation dampener 100, which in results in a better service life. Because the manufacturing process may be automated, construction involves lower labor costs .
[0022] FIGURE 2 is a sectional side view of portions of the composite pulsation dampener of FIGURE 1. The composite pulsation dampener has an exterior wall 200 and, in the example shown, includes a pressure drop tube 201 fitted to an opening (inlet or, preferably, outlet) through the exterior wall and extending into the interior space. Vent and drain connections (not shown in FIGURES 1 or 2) are also provided, external of the device and possibly integrally formed with nozzles supplied for making connections to the inlet and outlet of the composite pulsation device. For simplicity and clarity, the pressure drop tube or alternative pressure drop device is not shown in FIGURES 1 or 3-6, although the use of such devices with the embodiments of those figures is expressly contemplated.
[0023] FIGURE 3 is a cutaway perspective view of a composite pulsation dampener according to another embodiment of the disclosure. The pulsation dampener 300 includes an inlet (or intake) 301 and outlet 302, each formed with a disk-shaped flange at the end extending into the interior of the body and surrounding an opening through the body of the pulsation dampener 300. Exterior annular flanges are provided on each of the inlet 301 and outlet 302 for securing the respective fluid conduit to other piping. The body of the pulsation dampener 300 is formed of identical half structures each including dome-shaped or elliptical end structures 303 and 304 at either end of a cylindrical center portion 305. The embodiment of FIGURE 3 includes an integrated nozzle design of a metallic dome and piping flanges, with cylinder wall port openings for vent and drain connections. The integrated nozzle flanges provide mounting locations for both vertical and horizontal support structures and lifting lugs.
[0024] The materials of the body of the pulsation dampener 300 are the same as those described above in connection with the embodiment of FIGURE 1. A non-load bearing polymer liner inside the pressure vessel is chemically compatible with the drilling fluids used in the oil and gas industry, and is capable of sealing the fluids under pressures as great as 10,000 pounds per square inch (psi) (or even higher, up to 15,000 or even 20,000 psi) , and further may be continuously operating within the cyclic pressures of the system, and at temperatures ranging from -65°F to 250°F.
[0025] A galvanic corrosion barrier and shock isolation shear ply is located between the composite dome and metallic nozzles. This shear ply reduces the galvanic incompatibility of carbon and metals. In addition, the shear ply operates as an acoustic or shock isolation system, reducing the acoustic emissions of the pulsation control device. These improvements extend the service life of the pulsation control device.
[0026] FIGURE 4 is an external perspective view of the composite pulsation dampener of FIGURE 3 in a vertical mount orientation. Mounting brackets 400 secured to the external annular flanges on the inlet 301 and the outlet 302 may be used to support the pulsation dampener 300.
[0027] FIGURE 5 is an external perspective view of the composite pulsation dampener of FIGURE 3 in a vertical mount orientation. A mounting stand 500 secured to the external annular flange on one of the inlet 301 and the outlet 302 may be used to support the pulsation dampener 300. [0028] FIGURE 6 is a cutaway perspective view of portions of the composite pulsation dampener of FIGURE 3. The embodiment shown includes an extended inlet nozzle 602 on the inlet 601. The dome flange of the nozzle protrudes a distance into the pressure vessel, thus reducing the erosion effects of the polymer liner, extending the service life of the pulsation control device.
[0029] Although the present disclosure has been described with exemplary embodiments, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims. The composite pulsation dampener.
