ASME SA179 Seamless Cold Drawn Low Carbon U Tubes For Calderas
ASME SA179 Seamless Cold Drawn Low Carbon U Tubes For Calderas
YuHong can offer SA179 U carbon steel tubes and we sell these products with highest quality in more than 70 countries.
ASME SA179 this specification covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular, heat exchanger,
condensers, and other heat transfer services. SA 179 carbon steel tube is supplied and produced by cold drawning method and it is widely used in industries such as petroleum, chemical, medical, food, light industry, machinery, instrument, include industrial pipeline and mechanical structure parts, etc.
U tubes are manufactured by bending straight tubes. Bending is done cold on an automatic U-bend. To ensure tube wall thinning and diameter ovality are controlled, tube bending is accomplished with a mandrel inserted into the tube. What's more, the U-bend of the U-tube is stress relieved under controlled conditions and cycles for extended life.
