Spiral Wound Gaskets in full range of metal
The company has modern production facilities and well equiped laboratory facilities like compression and recovery testing, leaking testing etc.
Dave Engineers manufactures strictly to the standards by ASME B16.20 (Formerly API 601), DIN, JIS or any special shapes and sizes.
Spiral Wound Gasket comprise a mix of metallic and filler material. The gasket has a metal wound outwards in a circular spiral with the filler material wound in the samemanner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.
Spiral Wound Gaskets can be reinforced with inner ring or outer ring or both. The outer centering ring holds the gasket centrally within the bolt circle and inner ring improves. The axial rigidity and resilience of gaskets.
