5505H Flange Bolt Springs TECHNICAL DATA Service: High-temperature flanges in non-corrosive service Temperature: to 1100°F (595°C) maximum Color: Black Material: H13 Chromium Steel with oxide coating Typical Installation: Use drawing from installation instructions (071071). 5505H Springs are offered in three standard loads: 30ksi, 45ksi and 60ksi bolt stresses, with one spring installed under each side of the bolt or stud.
For bolted heat exchangers and pipe flanges Maintains constant compression on gasket seals Eliminate leakage problems caused by thermal cycling, vibration and pressure surges High temperature capability Gaskets perform the sealing in most flanges, but the flange bolts provide the compression necessary to make gaskets work. Maintaining constant bolt load is essential to proper compression of a gasket. In normal operation, flanges are subject to thermal expansion and contraction, pressure surges, vibration and gasket creep. All these factors serve to decrease bolt load and gasket compression which can lead to premature leakage and failure of gasketed joints.
Technical data reflects results of laboratory tests and is intended to indicate general characteristics only. A.W. Chesterton Company disclaims all warranties expressed, or implied, including warranties of merchantability and fitness for a particular purpose or use. Liability, if any is limited to product replacement only.
Chesterton’s 5505H Flange Springs compensate for all these factors. These specially designed, high-strength springs deliver a reserve of elastic energy to each bolt, allowing them to maintain constant load on the flange and gasket during normal operation, or during system upsets. Properly selected and installed, Cheterton’s 5505H Flange Springs can provide dramatic improvements in leakage performance and service life.
