Cast Iron Pipe - an overview ScienceDirect TopicsCast iron. Cast iron is less expensive than steel and in some cases more corrosion resistant. It is commonly used for underground water service. The use of cast iron pipe is generally undesirable in oil or gas service because of its brittleness. If heated by fire and then quenched cast iron can fail.
ASTM A513 Type 1A mechanical tubing is produced from hot rolled strip steel while A513 Type 1B tubing is produced from hot rolled strip steel that has been pickled to remove scale then oiled to provide a cleaner surface than hot rolled. Electrical resistance welded tubes are produced from a hot rolled scale-free strip which is formed by rolls at room temperature into a tubular shape.
