Systems and methods for efficient on-line pigging of a coker furnace without interruption of the delayed coking process, which will save time and money during the delayed coking process. This system can be retrofitted to existing coker furnaces.

Provided herein are a pipeline inspection system for effectively managing a pipeline by inspecting a state of the pipeline while moving along the pipeline. Moreover, the pipeline inspection system and the maintenance method using the same can improve scale removal efficiency by removing scale accumulated on the inner wall of the pipeline with ultrasonic vibrations, and prevent water leakage due to the corrosion of the inner wall of the pipeline.

A horizontal collecting-while-sending-ball water separator, has an outer barrel, the side wall of the outer barrel has a ball collection opening, a water outlet, a ball sending opening and a water inlet; a water inlet and outlet control valve connects to the water outlet and the water inlet, the control valve comprises an inner barrel, the inner barrel is divided into a first conduit and a second conduit, the side wall of the first conduit has two first openings, the side wall of the second conduit has two second openings; the separator can collect and send balls synchronously.

A pipeline sphere is shown which houses an electronics package. The sphere is formed as a hollow elastomeric body having a predetermined wall thickness and an initially void interior. A carrier tube is positioned within the initially void interior of the sphere and is supported by oppositely arranged carrier plates which are themselves embedded within oppositely arranged end openings of the sphere. A removable inflation valve is contained in one of the valve plates at a first end of the carrier tube. The carrier tube has a plurality of apertures formed through its wall to enable inflating or deflating the sphere. One electronics package that can be used is an electrical tracking device.

The present invention relates to an apparatus for circulating balls. An embodiment of the present invention includes: a circulation path for circulating balls and fluid, the circulation path comprising a cooling water tube of a heat exchange unit; a pump arranged in the circulation path for pumping the balls and fluid; and a counter for counting the time and the number of the balls in relation to the circulation of the balls.

A cleaning ball with a naturally derived material bonded to a surface of the cleaning ball for a condenser in a power plant is capable of performing efficient cleaning, and even if the material bonded to the surface of the ball is discharged to the ocean, the material does not cause damages to a marine environment. The cleaning ball includes a sponge rubber ball configured to deform and clean a heat transfer tube of the condenser; and a skin layer including crushed sand bonded to a surface of the sponge rubber ball. The crushed sand comprises sandstone containing granite particles, and the crushed sand has a particle size between 0.05 mm and 2.00 mm, and the skin layer is formed in concave and convex shapes on a non-deformed shape of the sponge rubber ball, and is configured to deform corresponding to deformation of the sponge rubber ball.

In a hydraulic circuit including a ball circulation pump skid, a single pump, and a set of valves in a manifold of the ball circulation pump skid, the pump and valves are operated to move all fluid in the hydraulic circuit alternately along two paths through an operative device and a ball collection capsule in the manifold, so that none of the balls ever enter the pump. The first path enables (a) ball-containing fluid flow from the operative device to the ball collection capsule and (b) ball-free fluid flow from the ball collection capsule to the exactly one pump and back to the manifold. The second path provides for (c) ball-free fluid flow from the pump to the ball collection capsule and (d) ball-entraining flow from the ball collection capsule to the operative device.
