A pulsation damper for a condensate pump comprising a housing defining a fluid chamber having a liquid inlet connectable to an outlet of the condensate pump, an air inlet, and a liquid outlet, wherein the air inlet includes a one-way valve configured to selectively introduce air into the housing to maintain a first air pocket within the fluid chamber as liquid flows through the fluid chamber, wherein the liquid outlet is located outside the first air pocket, and wherein the air pocket is configured to dissipate pulsations within liquid entering the housing at the liquid inlet prior to the liquid discharging via the liquid outlet.

The invention relates to a sound absorber comprising a housing with an inlet for connection with the exhaust gas line of a suction gripper, the housing comprising at least one elastic segment comprising at least one though hole, and also to a process of sound absorption for a suction gripper. The application of pressurized exhaust gas to the elastic segment leads to its expansion and to enlargement of the opening of the through hole. The expansion and/or the elasticity of the elastic segment in which the through hole is arranged, and the passing of the exhaust gas through the opened through hole in the elastic segment reduce the sound emitted along with the exhaust gas.

Disclosed are processes, devices and systems for preventing overpressurization of subsea production equipment and flowlines in which fluid passes through a high integrity pressure protection system (HIPPS). In embodiments, a container having a piston seal therein can be attached to the piping. In embodiments, a device having a piston seal therein and connected to a fluid receptacle can be attached to the piping. In the event of a pressure surge, fluid can be diverted to the container or the device, thereby lessening the pressure surge. In embodiments, the container or device includes a resetting force to return the piston seal to its original sealed position. The use of the systems disclosed improve the life of the HIPPS valve, protects subsea equipment and flowlines, and enables a length and/or a wall thickness of a fortified pipeline zone downstream of the HIPPS to be reduced.

A conduit connection assembly includes a first conduit part and a second conduit part, assembled to form a conduit connection delimiting a first fluid conducting volume from a second fluid conducting volume. The first and second fluid conducting volumes communicate with each other via a pressure change inducing device. During use of the conduit connection assembly, the pressure in the first conducting volume is higher than the pressure in the second conducting volume. A cavity is formed between the first and second conduit parts at a distance from the first fluid conducting volume, and a draining connection is adapted to provide a communication between the cavity and the second fluid conducting volume. A slot, formed by the assembly of the two conduit parts, provides a communication between the first fluid conducting volume and the cavity.
