Upon removal of the protection covers, great care must be observed not to damage the flare surface during handling. Clean joint surfaces prior to installation.<\/p>\r\n\r\n<span style=\"font-size: 18pt;\"><strong>Hot Work<\/strong><\/span>\r\n\r\n<p>No hot work such as welding, flame cutting, brazing, etc. should be done on or close to metal pipes where the heat generated would cause damage to the inside liner material.<\/p>\r\n\r\n<span style=\"font-size: 18pt;\"><strong>Thermal Cycling<\/strong><\/span>\r\n\r\n<p>Retorque after the first cycling process and after the system has cooled down to ambient temperature. Do not removed lined pipes, fittings and valve which are above ambient temperature.<\/p>\r\n\r\n<span style=\"font-size: 18pt;\"><strong>Vent Holes<\/strong><\/span>\r\n\r\n<p>Vents relieve pressure between the liner and pipe wall and also serve to indicate leaks. Ensure that vents are not clogged up. On insulated pipes, vents should be extended through and out of the insulation using the optional Vent Boss Fitment. Vents should be periodically inspected. Do not use sharp objects to clean clogged vents.<\/p>\r\n\r\n<span style=\"font-size: 18pt;\"><strong>Permeation<\/strong><\/span>\r\n\r\n<p>Permeation is the penetration of the fluid molecules through the lining and can be reduced with increased liner thickness and appropriate lining material selection. Permeation will also increase with increase in service temperature.<\/p>\r\n\r\n<span style=\"font-size: 18pt;\"><strong>Creep<\/strong><\/span>\r\n\r\n<p>This is the deformation of PTFE over time under the influence of applied stress and increases at elevated temperatures.<\/p>\r\n\r\n<span style=\"font-size: 18pt;\"><strong>Low Temperature Service &amp; Storage<\/strong><\/span>\r\n\r\n<p>Cold temperatures can cause brittleness in PP and PVDF lined components.
