In 1989 we were oil refinery firefighters. At oil refineries, sandbagging is the customary procedure to temporarily seal potentially explosive process sewer drains during hotwork. But sandbagging can be a messy, drain-fouling, labor-intensive technique. We talked of a better way. Eventually we came up with our Orignial Inserts.
NsertAseal Corporation still sells Original Inserts, but our main focus now involves retrofitting sewer systems with water seals that are semi-permanently caulked or grouted into place. These seals allow waste fluid to pass through drains into the sewer system normally, but stop fugitive emissions from leaching back out into the atmosphere.

When old systems have to be brought into regulatory compliance, our products can save refineries time, money, and space. NsertAseal inserts can also be used in new construction applications at a fraction of the cost and space requirements of conventional fittings when water seal vapor barriers are needed.
Box Traps, like extremely large or odd-sized VPT's, are custom designed to your specifications. After collecting precise measurements, our fabrication team adapts the water trap concept to each particular installation. In all cases, an NsertAseal representative works with your plant personnel to produce the best solution to your vapor control problems.
The NsertAseal Access Hole seal is designed to seal large (22" to 34") access holes (manholes). Our seals are fitted into place with caulk and gaskets. Access hole lids are replaced after installation. These seals stop the migration of sewer gas to the atmosphere.
If required for the application, they can be fitted with a water seal to allow entry of wastewater to the process sewer system while preventing sewer gas from escaping into the atmosphere.

During a recent compliance upgrade project at a large refinery, government mandates threatened to cost a potential customer a great deal of time, planning, and expense. Regulations required that this refinery's drain sumps be fitted with seals to prevent fugitive emissions. These drain openings were large and numerous, and they were extremely corroded, with parts of the original vapor trap system missing.
We make sewer seals for oil refinery sewer drains. Oil refinery sewer emissions from process sewer drains present serious regulatory problems.
Federal and state environmental protection agencies and regulations such as NESHAP (National Emission Standards for Hazardous Air Pollutants) and QQQ (40 CFR Part 63, Subpart QQQ) require oil refineries to protect the atmosphere against pollution by carbon organic compounds (COC's) and harmful substances such as benzene released by uncontrolled sewer catch basins, drain hubs, and manholes open to the atmosphere.
