Product Description
Product Description


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.

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

Company Profile


DRACHMA (ZHANGJIAGANG) MATERIAL CO.LTD has two main production plants. Zhangjiagang plant is responsible for the rough forming of workpieces, mainly forging process; While Hangzhou plant is mainly responsible for precision machining, welding and inspection of products. We implement this layout mainly to use the industrial advantages of each region to achieve maximum economic benefits.


Traditional processing enterprises often do not have such ability, the lack of blank forming ability is unable to achieve the optimal use of materials, resulting in excessive processing allowance, long cycle, high cost. Zhangjiagang is located in the southern jiangsu province, which has the strongest forging capacity in China. It has a good supporting industry and can realize the diversified production of forging and pressing blanks. Thanks to this, the product cycle of our company is faster, the cost performance is higher, and the forging products have better mechanical properties than the products directly processed by rod or plate.


In addition, our company has strong welding ability, which can weld and assemble parts to achieve system delivery. We adopt the mode of automatic robot welding and manual precision welding to achieve flexibility and high quality.
