Rugged gaskets with a proprietary coating

By Chemical Engineering |

Garlock Pipeline Technologies

This company’s new Evolution isolation gaskets (photo) are fully coated and offer a thin, 1/8-in. design, which minimizes the difficulties often encountered when attempting to install thicker isolating gaskets. The full-coating encapsulation allows the gasket to be hydrotested and left in the pipeline with the same isolation properties as before it was tested. The proprietary coating material is said to be extremely resistant to abrasion and impact, while providing chemical resistance to H 2 S, steam, CO, CO 2 and other chemicals. This fully encapsulated coating also prevents the need for expensive exotic cores, as it eliminates contact to exposed metal. According to the manufacturer, the Evolution gasket features the highest tightness parameters of any product currently available. Evolution gaskets also feature pressure-energized seals, a fire-safe Inconel 718 c-ring, built to match pipe bore, a short moment arm, moisture and humidity resistance, zero creep relaxation and a 316L stainless-steel core. — Garlock Pipeline Technologies (GPT), Houston
