Cortec, a leader in corrosion control technologies, has introduced a new corrosion inhibiting additive which is compatible with diesel fuel tanks and systems.
Corrosion is a common problem on carbon steel components shipped overseas or stored for months in humid climates. Metals in good condition when manufactured may be severely corroded by the time they reach their destination or are unpacked from warehouse storage, said a statement from the company.
Cortec has frequently addressed this problem by offering integrated solutions in the form of VpCI films, coatings, or other delivery systems that best suit the application and are relatively easy and economical to use.
During its 40-year history, Cortec has also developed many new VpCI products that meet specific end user needs and introduce these benefits to others.
This recently occurred with Cortec’s development of a new VpCI fuel additive for the protection of diesel fuel tanks and systems, said the statement.
A corrosion problem on carbon steel diesel fuel tanks of a major manufacturer’s heavy equipment prompted the discovery. Corrosion would occur on the equipment tanks after about one month of overseas shipment and would increase during long months of storage in the humid climate of Brazil, it added.
Cortec R&D responded to the problem by designing VpCI-706, an additive fully compatible with diesel and biodiesel fuel and tailored to work in diesel tanks and systems.
The product provides superior corrosion protection for ferrous metal surfaces both in contact with the fuel and above the fuel level. VpCI-706 has many important features including:
•Use in operation, storage, and shipment
•Fully compatible with diesel and biodiesel fuels
•Provides protection in liquid and vapor phase, and at liquid/air interface
•Does not contain trace metals, chlorides, chromates, nitrites, or phosphates
•Does not contain additives known to create precipitates and filter issues
•Can be fogged or poured directly into gas tanks
According to Cortec, after running tests and ultimately developing VpCI-706, the company did a trial on the heavy equipment carbon steel tanks that had inspired the product.
The additive was applied to the heavy equipment tanks (which were filled with an operational amount of diesel fuel for equipment loading and unloading) before approximately one month of shipment to Brazil, where further storage would occur.
When the equipment arrived at its destination, the filler necks of the untreated and treated tanks were compared. Corrosion was found on the filler necks of the untreated tanks, but the filler necks of the treated tanks had been preserved, and the customer expressed the desire to adopt the new protection method, said the statement from Cortec.
Adding VpCI-706 to diesel tanks before shipment or storage is an important new strategy for protecting truck and heavy equipment fuel tanks and systems from corrosion. It lowers the risk of monetary loss and customer dissatisfaction from equipment that arrives at its destination in a corroded condition, it stated.
VpCI-706 is an important addition to Cortec’s range of integrated solutions as a corrosion inhibiting additive that is compatible with diesel fuel, protects at a very low concentration, and can be used during equipment operation, it added.
