Vacuum Bellows & Fittings - Highlight Technology Corp. - #2

■ HTC tube fittings are convenient "building block" components. They offer great flexibility in the design and construction of high and ultra-high vacuum system.

■There are two type of bellows of HTCs products, or flexible metal hoses. "Flexible hoses" have concertina walls made by pressurizing a thin-wall tube, they can be bent but not be compressed. ^{The other type is} "F^lex^{ible bellows connections}", ^{this type can bent and compressed.} W^{hen pos­}sible, design the system so that the bellows make only a single bend or curve. Multiple bends concentrate stress at minimum radius points, reducing life expectancy during flexing or vibra­tion. An elbow on one or both ends will usually eliminate multiple bends. It is difficult to make a short bellows fit between parallel flange faces that are not coaxial.

■ Flexible hoses : 304 S.S.

■ Flexible bellows connections : 31 6Ti, 321 S.S., 316L S.S, 316 S.S., 304 S.S.

■ Htc tube fitting are made from welded pipe or tube.

■ Larger or special size available upon request

■ Seamless pipe or tube are available upon request.
