Description<\/strong><\/p>\n ZHW\u00ae PTFE bellows are manufactured from virgin paste-extruded PTFE. They are designed for maximum flex-life in a wide range of high temperature\/high purity Chemical Process Industry (CPI) applications. General ZHW\u00ae bellows or flexible connectors or expansion joints, are used in piping systems to absorb vibration caused by rotating equipment, to absorb thermal expansion and contraction of piping systems and protect stress-sensitive process equipment (graphite, glass, glass-lined steel, FRP, dual laminate, etc.). PTFE is ideal for use as a bellow material because of its near universal corrosion resistance, low spring rate and near unlimited flexible life. Providing this system flexibility, any bellow is virtually designed to be the most sensitive link in a piping system. ZHW\u2019s engineering team has conducted long term PTFE studies to ensure comprehensive understanding of all aspects of the bellow design, manufacture and quality control to maximize performance and safety. We can supply our PTFE with static dissipating (antistatic) properties suitable for use with solvents and other liquids where static build up is an issue.<\/p>\n The steps in the engineering & manufacturing optimization process were:<\/p>\n For more information about the features and benefits of the ZHW PTFE bellows, Download our brochure<\/strong><\/a><\/span>.<\/strong><\/p>\n For up-to-date pricing and availability information.
