single crystal furnace welded bellow for accelerator and vacuum industry

Drachma Material main products are metal welded bellows, magnetic fluid seals and ultra-high vacuum components. Supply to accelerator, semiconductor, TFT-LCD, photovoltaic and other industries, has been recognized by technology, product quality.

———Brief Introduction

Welding bellows is a new type of component emerging at home and abroad in recent years. It can be used as a sensitive component, sealing component, isolation medium, pipeline connection and temperature compensator. It in addition to pressure resistance, temperature resistance, corrosion resistance, good sealing and other advantages, compared with the traditional shape of bellows there are two outstanding advantages: large deformation, long life.

———Schematic diagram

Its composition is composed of two formed hollow diaphragm with concentric circle for inner edge welding to form a diaphragm pair, and then a plurality of diaphragm pairs stacked together for outer edge welding to form a corrugated section, and then at both ends and end plate metal welding combined into a bellows group, so that it can be reciprocated with other moving parts according to the external needs
