    摘要: A method of providing at least one projection on a tubular body. The tubular body may be one required by the oil and gas industry for use in recovery of and transporting of crude oil or gas, namely oil-country-tubular goods. The projection has a predetermined form such as a blade, ribbing, or the like stand-off projection. The method provides materials capable of being molded, applying a mold to a tubular body, and molding the material using the mold onto the tubular body.
