DESCRIPTION

Spool type rubber expansion joints has the same function with mould pressing type rubber expansion joints, used in metal pipe system for vibration isolation, reducing noise and displacement compensation. Comparing to compression molding rubber expansion joints, spool type rubber expansion joints mainly showed two merits: flexible structure and high pressure bearing effect. It can satisfy different installation length and different flange connection dimension requirements.


Since mould pressing product is limited by mould size, the length are all the same, Lanphan spool type rubber expansion joints has already met all kinds of structure, we can manufacture non-standard products. Besides, since spool type rubber expansion joints are not limited by mould size, its skeleton layers is 2-4 couples more than mould pressing products, therefore, it has higher pressure bearing capacity.
