Spiral Wound Gaskets
Spiral Wound Gaskets
Welcome to S.P. Engineers, a trusted name in the manufacturing of spiral wound gaskets since 1995. As industry leaders in sealing solutions, we have built our reputation through innovation, customer-centric service, and adherence to the highest quality standards.
Our gaskets cater to diverse industries, including refineries, petrochemical plants, chemical processing units, steam lines, and other process-driven sectors. With cutting-edge technology and unwavering dedication, we provide reliable solutions to complex sealing challenges. Customization is at the heart of our offerings, ensuring our products meet international standards like BS, API, ASME, and DIN or specific client requirements.
Why Choose Spiral Wound Gaskets from S.P. Engineers?
Spiral wound gaskets are engineered with a V-shaped metallic strip spirally wound with a soft filler material. This design offers exceptional resilience from the metal strip and superior sealing capability from the filler.
The combination of these materials makes our gaskets ideal for fluctuating temperature and pressure conditions. Depending on your requirements, these gaskets can be equipped with inner and/or outer rings for added functionality.
Product Range
- Combines a sealing element with solid metal inner and outer rings for added structural support.
