Shot blast cleaning is not new to the pipeline industry. For many years much of the pipe laid has been shot blast cleaned and coated in stationary coating plants or rail head yards. Stationary plants generally produce an excellent cleaning coating job, but have some drawbacks. Pipe must be handled more times, coatings can be damaged in shipping, bending machines can damage coatings and damage can occur when lining up the joints for welding. Another obvious drawback is that each weld area must be cleaned and coated in the field. Each field patch is a possible trouble spot in the future. Cleaning and coating pipe in the field provides a more continuous coating, but field cleaning is not, at present, as good as it should be.
