We manufacture and distribute Dinaseal and Lamons brand spiral wound gaskets in various materials.
Spiral wound gaskets
Are manufactured according to ASME B16.20 Standard and are designed to be installed between ASME B16.5, B16.47 Series A or B and DIN flanges in all sizes and pressure classes covered by these standards.
We stock a wide variety and combinations of different models, classes and materials.
Spiral wound gasket components
A spiral wound gasket has the following components: The spiral or winding, which is the flexible part of the gasket and in charge of generating the static seal, which is combined with a profiled metal tape and a filler material such as flexible graphite, mica graphite, ceramic or PTFE. In addition, for ease of gasket assembly, the gasket has a centralizing outer ring usually made of carbon steel or stainless steel. Finally, an inner ring serves to mechanically protect the winding.
The above does not imply that a spiral wound gasket has these three components together, it can have:
- Only the winding (W)
- The winding plus the outer ring (WR)
- The above three components (WRI)
The spiral wound gasket is the ideal and economical sealing solution for all types of industrial applications.
Our represented Lamons and IDT, also have other types of very special spiral wound gaskets to seal flanges in special applications, where zero leakage is required either by the characteristic of the fluid, the process or the area. This type of gaskets are highly recommended in food, pharmaceutical, chemical, petrochemical or refinery industries.
We have specialized machinery and equipment for the manufacture of spiral wound gaskets in any diameter, material and pressure class that allows us to attend emergencies 24 hours a day, 7 days a week.
