(This message was added in version 6.7.0.) in /home4/zhwgroup/public_html/wp-includes/functions.php on line 6114ZHW rectangular bellows have been designed to control vibration, reduce noise, relieve stress, prevent system shock and compensate for misalignment and movement. Use of braided metal connectors for applications such as pumps, compressors, and other mechanical equipment will enhance the overall operation of the system.<\/p>\n
ZHW rectangular bellows are used in lots of applications, where it concerns safety, health, environment, durability and lifetime. Bellows are made from stainless steel strip which is first welded to a thin walled tube and formed to a bellow afterwards.<\/p>\n
Bellows are normally unbraided and capable to absorb axial, lateral and angular movements while being under low or higher pressures and temperatures. Due to the construction techniques involved the bellows are relative light compared to equivalent non-metallic bellow alternatives in the market.<\/p>\n
Description<\/strong><\/p>\n ZHW’s “RBFF” series bellows system provides the most economical installation. Rectangular bellows is the base member of ZHW metal expansion bellows family, consisting of a bellows element and end fittings.<\/p>\n Absorbs and isolates troublesome pipeline vibrations<\/strong><\/p>\n For more information about the features and benefits of the ZHW Rectangular Bellows Series RBFF21, Download our brochure<\/strong><\/a><\/span>.<\/strong><\/p>\n For up-to-date pricing and availability information.
