Crane Packing introduced its “CHEMLON” line of Teflon-based packing material for use on pumps, valves, hydraulic fittings and cylinders, coaxial cables, and gaskets in 1948. [5] Old John Crane Advertisement. In 1950, Crane Packing purchased 26 acres (110,000 m 2) of land in Morton Grove, Illinois, a suburb of Chicago. Construction began on ...
During the 1920s, when Crane expanded overseas, the company was the world's leading manufacturer of valves and fittings. Company sales rose to over US$300 million per annum by the mid-1950s. In 1959, the Crane family sold their control of the company, and the new owners began to turn Crane into a global conglomerate that made aerospace ...
Creating a proper plunger alignment is critical for correct flow and a long wear life. Stuffing box components are of stainless steel, brass or other application-specific materials. Compression packing is rigorously tested to ensure effective sealing in valves, pumps, agitators, and other rotary equipment.
It has a donut-like rubber seal, known as an elastomeric packing unit, reinforced with steel ribs. The packing unit is situated in the BOP housing between the head and hydraulic piston. When the piston is actuated, its upward thrust forces the packing unit to constrict, like a sphincter, sealing the annulus or openhole. Annular preventers have ...

This packing is a wearable material and will have to be replaced during maintenance. With a smooth stem the ends are threaded to allow connection to the plug and the actuator. The stem must not only withstand a large amount of compression force during valve closure, but also have high tensile strength during valve opening.
Material handling equipment (MHE) is mechanical equipment used for the movement, storage, control, and protection of materials, goods and products throughout the process of manufacturing, distribution, consumption, and disposal. [1]
Super-Raschig rings Structured packing. In chemical processing, a packed bed is a hollow tube, pipe, or other vessel that is filled with a packing material. The packed bed can be randomly filled with small objects like Raschig rings or else it can be a specifically designed structured packing. Packed beds may also contain catalyst particles or ...
