tube-nozzle-header connections

English to Polish Tech/Engineering Engineering (general)

"The Solar Two receiver was designed and built by Boeing's Rocketdyne division. It comprised a series of panels (each made of 32 thin-walled, stainless steel tubes) through which the molten salt flows in a serpentine path. The panels form a cylindrical shell surrounding piping, structural supports, and control equipment. The external surfaces of the tubes were coated with a black PyromarkTM paint that was robust, resistant to high temperatures and thermal cycling, and absorbs 95% of the incident sunlight. The receiver design has been optimized to absorb a maximum amount of solar energy while reducing the heat losses due to convection and radiation. The design, which included laser-welding, sophisticated tube-nozzle-header connections, a tube clip design that facilitates tube expansion and contraction, and non-contact flux measurement devices, allowed the receiver to rapidly change temperature without being damaged. For example, during a cloud passage, the receiver could safely change from 290 to 570ºC (554 to 1,058ºF) in less than one minute."
