Access Plug Flange, Inc. manufactures the most durable and wide-ranging inspection plugs for the oil, gas and petrochemical industry. APF, Inc.’s acquisition of it’s own elastomer molding facility has been instrumental in the development of “matching inspection plugs to process temperatures”. This ability is what allows our product line to ensure the integrity of the system, even if the insulation core is lost or discarded during the inspection process. Our inspection plugs have a reputation for durability and quality. Other inspection plugs may cost less, but can fall apart after a short period of time when exposed to the elements. The labor cost for replacing these damaged inspection plugs in the field will exceed, by far, any savings generated by using lesser quality inspection plugs. We are not bragging when we say “The Worldwide Leader In Inspection Port Technology.”, we have the facts to prove it.

We believe the energy landscape of tomorrow will have two major themes – conservation of existing resources, and development of new ones – and we believe aerogel will play a big part in both. The role of insulation in conservation is clear; by keeping hot things hot and cold things cold, insulation makes energy go where we need it. But did you also know that flexible aerogel insulation products can help in the development of unconventional sources of energy? Hotter, colder, further, faster – see how Pyrogel®, Cryogel® and Spaceloft® are helping to build the future of energy, today.
