Plastic caps with corrosion inhibitors protect pipe in transit
The CorroLogic CorrPlug caps (photo) protect pipe ends, pipe threads and other tubular objects from corrosion, mechanical damage and intrusion (by foreign objects) during storage and shipping. These pipe caps are constructed from heavy-wall black polyethylene that contains proprietary, vapor-phase corrosion inhibitors. They are designed for easy installation and removal, which helps to reduce labor needs. During humidity testing, pipe threads equipped with these caps showed a significant advantage in corrosion resistance compared to those capped with regular plastic caps that contain no corrosion inhibitors, says the company. These caps are made to order in most standard NPT pipe sizes, ranging from 0.25 to 65 in. in dia. They protect carbon steel, stainless steel, copper, brass and aluminum pipes. — Cortec Corp., St. Paul, Minn.
