New Practice for Application of Thermal Spray Aluminum (TSA) Coating to Carbon Steel Pipe

1. Scope

The promotion of knowledge, the stimulation of research, and the development of specifications, test methods, terminology, and other types of standards relating to cast or wrought steels, stainless steels and related alloys and ferrous alloys.

Areas of Interest: The Committee's interest includes the following materials: carbon and alloy steels, tool steels, tin mill products, corrosion and heat-resistant alloys, super-strength alloys, and clad steels.
The Committee, unless specifically requested by the Chairman of the Committee having prime responsibility, is not concerned with materials which are the interest to Committees; A06 on Magnetic Properties, B02 on Nonferrous Metals and Alloys, B04 on Metallic Materials for Thermostats and for Electrical Resistance, Heating, and Contacts; and F04 on Surgical Implants.

The Committee specifically excludes the following areas of interest:
* Aluminum-coated, zinc-coated, or terne-coated steel products covered by Committee A05.
* Alloys in those forms for which the principal use results from specifically controlled electrical resistance, thermal expansion, or magnetic characteristics which pertain to electrical resistance devices, electrical contacts, thermostats, and electrical steel.
* Materials for surgical implants.

Policy on Material Specification Coverage: The material specifications prepared by the Committee are available for use by producers and users anywhere in the world. To maintain a practical limit to the amount of committee effort, the Committee will prepare and administer specifications within its expertise. Requests for new specifications or standards or for new grades or types of material should be supported by a regulatory body, a code-writing body or a member of ASTM.


Thermal spray aluminum (TSA); atmospheric corrosion; corrosion under insulation (CUI); piping; surface preparation;


This standard has been requested by user members of the Materials Technology Institute of the Chemical Process Industries (MTI), who believe that creation of an ASTM Standard will facilitate its use by smaller companies. (It is already being used by larger companies as a proprietary requirement.) It will be used by chemical producers and petroleum refiners who have insulated, high temperature piping systems and desire to minimize corrosion.

The title and scope are in draft form and are under development within this ASTM Committee.
