New York Port Engineers Hears Paper On Surface Preparation Of Steel

The Society of Marine Port Engineers New York, N.Y., Inc. met on September 21 at the Downtown Athletic Club in New York City.

At the technical session, which was preceded by a social hour and dinner, a paper was presented on "Surface Preparation of Steel for Painting and Other Coating Applications," by H.W. Hitzrot, Research Department, Bethlehem Steel Corporation, Shipbuilding Division. The sponsor was Thomas J. Young of the United States Lines.

In his paper, Mr. Hitzrot summarizes the findings of a number of Bethlehem Steel Corporation research projects on the surface preparation of steel by abrasive blast cleaning in the construction, shipbuilding and ship repair industries. The report is divided into sections on (1) Steel Abrasives, and (2) Mineral Abrasives.

Steel abrasives are of two major types: shot and grit. They are used in automatic wheel blasting units or in manual blast cabinets.

Mineral abrasives include slags, sands and oxides, which are generally angular in shape and are used for manual blast cleaning.

The types of abrasive recommended for various blast cleaning operations are summarized in the paper, and detailed information on specific applications is provided.
