The advantages of PTFE-lined rubber expansion joint.

PTFE-lined rubber expansion joints are more common in chemical pipelines, has become the main application of petroleum, chemical, textile and other industries corrosion-resistant joints, flange PTFE rubber expansion joints are mainly used in strong acid and alkali, strong high temperature, strong corrosive pipeline equipment, especially corrosive media, including: corrosive gas transmission pipe, exhaust pipe, steam pipe.
Pipeline lined with teflon rubber expansion energy-saving reasonable maintenance of rubber expansion joints are not corroded by the leaching medium. And acid and alkali-resistant rubber expansion joint originally had mechanical equipment and process performance did not receive a little harm, still can compensate for pipeline vibration to absorb pipeline displacement to reduce pipeline noise.
Rubber flexible expansion joint lined with tetrafluoro characteristics are as follows: the use of high temperature in strong corrosive media conditions, can meet the use of temperature range -60 degrees ~ 200 degrees, in this temperature range can meet all chemical media. Vacuum resistant, can be used under vacuum conditions, in chemical production, often due to cooling, longitudinal discharge, pump valve asynchronous operation and other cases caused by the local vacuum state. High pressure resistance, in the temperature range, can withstand the use of up to 3MPA pressure; after advanced lining process into a high density, sufficient thickness of PTFE lining layer, so that the product has superior anti-permeability. Standardized dimensions are used, especially in chemical pipelines, pipe fittings have strong interchangeability, providing great convenience for installation and spare parts.
