The production process of a standard spiral wound gasket made of stainless steel ring can be summarized in the following steps:
Material selection: The first step in the production process is to select the appropriate materials. The stainless steel ring is typically made of high-grade stainless steel such as 316 or 304, and the filler material is usually graphite or PTFE.
Cutting the ring: The stainless steel ring is cut to the desired size using a cutting machine. The ring should be cut precisely to ensure that it fits the gasket's intended application.
Winding the filler material: The graphite or PTFE filler material is wound around the stainless steel ring using a specialized machine. The winding process ensures that the filler material is distributed evenly around the ring.
Winding the outer ring: A second stainless steel ring is wound around the filler material, securing it in place. This outer ring is typically larger than the inner ring to provide additional support.
Spot welding: The outer ring is spot-welded to the inner ring at several points to ensure that the gasket maintains its shape.
Trimming: The gasket is trimmed to the correct size using a trimming machine. This ensures that the gasket fits precisely into the intended application.
Quality control: The final step in the production process is quality control. The gasket is inspected to ensure that it meets the required specifications, including its dimensions, material quality, and functionality.
