Read MoreThere are five main methods for detecting surface defects of square and rectangular tubes: 1. Eddy current inspection Eddy current testing includes basic eddy current testing, far-field eddy current testing, multi-frequency eddy current testing, and single-pulse eddy current testing. Using the eddy current sensor to magnetically induce metal materials, the type and shape of the surface defects of the…
Read MoreFor carbon steel pipe (CS pipe), it should be degreased first and then pickled, because grease is insoluble in acid solution. If pickling is performed first, neither the oil stains nor the rust covered by the oil stains can be removed. Degreasing pickling method for carbon seamless steel pipe: At present, the tank immersion method is often used in…
Read MoreOil casing pipe is the lifeblood of keeping oil wells running. Due to different geological conditions, the downhole stress state is complex, and the comprehensive action of tension, compression, bending and torsional stress acts on the pipe body, which puts forward higher requirements on the quality of the casing itself. Once the casing itself is damaged for some reason,…
Read MoreThe anti-corrosion operation we first discuss refers to the routine maintenance of spiral steel pipes that have not been treated with anti-corrosion treatment. Because of its good anti-corrosion performance, the anti-corrosion spiral steel pipe is relatively less affected by the season, but for conventional spiral steel pipes (SSAW) , summer is a season that is easy to be corroded….
