BB-401 Tubing Coatings for Oil Well Tubing

BB 401 is a fusion bonded thermosetting phenolic epoxy powder, recommended for use over a phenolic primer on the Internals of steel tubing which is in adverse temperature and pressure service and in contact with corrosive gases, oils, chemicals, waters and acids. This coating provides corrosion protection in:

  • High temperature environments (275°F).
  • High pressure environments.
  • Sweet and sour gas environments.
  • Oil Production
  • WAG Injection Systems

However, performance may be greatly dependent on the service conditions and downhole applications.

BB 401 meets the requirements of CSA Z 245.20-02 and 06.
