Rapidly Attachable Fluid Transfer Interface (RAFTI) is a standard interface developed by Orbit Fab for transferring fluids, e.g., propellants, in space. [1] It has been defined by a group of 30 companies. The interface specification has high and low pressure variants, both for operation between -40 °C and 120 °C. [2]
A cable gland (more often known in the U.S. as a cord grip, cable strain relief, cable connector or cable fitting) is a device designed to attach and secure the end of an electrical cable to the equipment. [1]
A single compression seal fitting may seal on a single or multiple elements. Sealing glands designed to seal on single elements consist of a body, cap, sealant and follower. When sealing on multiple elements, gland designs also include a seat and an anti-rotation pin to prevent wires or conductors from twisting and shearing.
A gland is a general type of stuffing box, used to seal a rotating or reciprocating shaft against a fluid. The most common example is in the head of a tap where the gland is usually packed with string which has been soaked in tallow or similar grease. The gland nut allows the packing material to be compressed to form a watertight seal and ...
An end-face mechanical seal generates heat from rubbing and viscous shear and must be cooled to assure good performance and reliable operation. Typically, cooling is provided by circulating fluid around the seal. This fluid, known as a flush, may be the same as the fluid being sealed or an entirely different fluid.
Because the oil pushes up against the inside wall of the pipe, the pipe pushes the oil back down causing a swirling of turbulence to occur which creates a drag force. When the polymer is added, it interacts with the oil and the wall to help reduce the contact of the oil with the wall. Degradation can occur on the polymers during the flow ...
Eccentric reducers exhibit a unique design with one side having a larger diameter and the other side being smaller and offset from the centerline. This offset configuration enables the eccentric reducer to maintain a consistent fluid level within the piping system, preventing air or gas accumulation.
A chemical or oil tanker connected to the pier with a marine loading arm. Since the earliest days of tankships, the need to safely and efficiently transfer bulk liquid to a moored ship has been fundamental. An insufficient solution to this problem led to one of the world's first oil tanker disasters. [7]
