Advantages for PTFE lined metal expansion joints

PTFE lined metal expansion joints, its outer body is stainless steel metal bellows or braided sleeve, inside lined with PTFE. It can withstand various concentrations of acid, alkali and salt, and also has the advantages of stainless steel expansion joints, shock resistance and so on.

High temperature resistance – working temperature up to 250℃.

Low temperature resistance – good mechanical toughness; 5% elongation can be maintained even when the temperature drops to -196℃.

Corrosion-resistant to most chemicals and solvents, it is resistant to strong acid and alkali, water and various organic solvents.

High lubrication – low coefficient of friction.

Does not stick – does not stick to anything.

Non-toxic – PTFE lined metal expansion joints is physiologically inert, and has no adverse reactions when it is implanted in the body as an artificial blood vessel and an organ for a long time.

Electrical insulation – PTFE lined metal expansion joints can resist 1500 volts high voltage.

Fluorine-lined metal expansion joints series products are of reliable quality and advanced technology, and are widely used in chemical, electric power, smelting, pharmaceutical, food, environmental protection, electroplating and other fields. They can pass various concentrations of acid, alkali, salt, etc., and have good corrosion resistance. of anti-corrosion pipes.In terms of heating, in order to prevent the deformation or damage of the pipeline due to thermal elongation or temperature stress when the heating pipeline is heated, it is necessary to set expansion joints on the pipeline to compensate for the thermal elongation of the pipeline, thereby reducing the stress on the pipe wall and the force acting on the valve or support structure.
