Welded bellows

Sealing element

It is used in the service environment to withstand the dynamic change of temperature, pressure dynamic change and medium corrosion and other complex conditions to meet the mechanical sealing performance, good sealing performance and long service life. Corrugated pipe materials are generally used INCONEL718, AM350, HastelloyB.C and other stainless steel, corrosion resistant high temperature alloy and so on. Bellows pressure can bear up to 5MPa.

 

Bellows mechanical seal in the hot oil pump, mechanical seal of pump series in petrochemical industry high temperature heavy oil medium, the good use of corrugated pipe has DBM, XL-604/606/609, YH-604/606/609, etc.
