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. We help control emissions of VOC's (Volatile Organic Compounds) by making products that place water seals in oil refinery process sewer drain systems. These water seals are easily caulked into place with no hot work or shutdown time required. Our sewer seals are easily installed, economical, cost effective, and involve low labor cost.

Bringing process drain systems into compliance with clean air requirements, making them safe from fire, and stopping odors can be a problem for oil refineries. NsertAseal Corporation has quick and cost-effective solutions. Our products are reliable. They do the job well. Installing our inserts is more economical than other sewer-sealing techniques, both when retrofitting existing systems, and in new-construction applications.

Our patented drain seals help the petrochemical industry comply with regulatory mandates and contribute to a safe, odor-free work environment. Our best-selling seals are our Vertical Pipe Trap (VPT) inserts for standard drain openings. We also produce large custom seals for junction boxes and catch basins, and custom cast VPT's to solve unique sewer drain problems on a case-by-case basis.

Our VPT's, Box Traps, and custom-fabricated seals provide a barrier against the emission of noxious, pungent, and worrisome odors from refinery sewer systems. Use of our ruggedly constructed and economical products demonstrates an oil refinery's desire to maintain a good relationship with employees and neighbors.
