- Weld Defects: Irregularities or flaws in the weld zone of a welded steel tube, including incomplete penetration, lack of fusion, or porosity, which may compromise the joint’s integrity and mechanical strength.<\/li>\n\n\n\n
- Seam Weld Cracks: Cracks or fissures in the welded seam of a steel tube, often caused by welding defects or excessive stress during manufacturing, potentially leading to leakage or failure under pressure.<\/li>\n\n\n\n
- Lamination: Separation or delamination of layers within the steel tube, typically caused by non-metallic inclusions or defects during the manufacturing process, which can weaken the tube’s structural integrity.<\/li>\n\n\n\n
- Surface Contamination: Foreign substances or contaminants present on the surface of a steel tube, such as oil, grease, dirt, or rust, which can hinder adhesion, surface treatment, or cause corrosion.<\/li>\n\n\n\n
- Dimensional Deviation: A defect where a steel tube’s dimensions, such as diameter, length, or straightness, deviate from the specified tolerances, potentially impacting compatibility, fitment, or assembly.<\/li>\n\n\n\n
- Bow: A defect in which a steel tube exhibits a deviation from straightness along its length, resulting in a curved or bent shape. Bowing can impact the tube’s fitment, alignment, and functionality, requiring additional measures for correction or adjustment.<\/li>\n\n\n\n
- Twist: A defect characterized by a rotational deviation in the alignment of a steel tube along its length. Twisting can affect the tube’s orientation, parallelism, or positioning, requiring corrective measures to ensure proper installation or assembly.<\/li>\n\n\n\n
- Flattening: A defect in which a steel tube experiences a reduction in its cross-sectional shape, resulting in a flattened or oval appearance. Flattening can occur during the manufacturing process or due to external forces, potentially affecting the tube’s structural integrity or dimensional accuracy.<\/li>\n\n\n\n
- Scalloping: A defect characterized by irregular, wave-like indentations or scalloped patterns on the surface of a steel tube. Scalloping can occur during the manufacturing process or due to improper handling, potentially impacting the tube’s aesthetics, corrosion resistance, or surface functionality.<\/li>\n\n\n\n
- Pitting: A defect marked by small, localized depressions or pits on the surface of a steel tube, typically caused by corrosion, oxidation, or exposure to aggressive environments. Pitting can compromise the tube’s structural integrity, aesthetics, or resistance to further corrosion.<\/li>\n\n\n\n
- Internal Erosion: A defect involving the gradual erosion or wearing away of the internal surface of a steel tube, often caused by the flow of fluids, chemicals, or abrasive materials. Internal erosion can lead to thinning of the tube wall, reduced flow efficiency, or potential leakage.<\/li>\n\n\n\n
- Bulging: A defect where a localized area of a steel tube exhibits an abnormal outward expansion or bulge, typically caused by internal pressure, excessive strain, or manufacturing inconsistencies. Bulging can compromise the tube’s dimensional accuracy, mechanical strength, or fitting compatibility.<\/li>\n\n\n\n
- Burr: A defect characterized by a raised or irregular edge or ridge on the surface of a steel tube, often formed during the cutting, drilling, or machining processes. Burrs can affect the tube’s smoothness, aesthetics, or interfere with assembly or surface treatment.<\/li>\n\n\n\n
- Out-of-Roundness: A defect where a steel tube deviates from a perfect circular shape, resulting in an irregular or non-uniform cross-section. Out-of-roundness can affect dimensional accuracy, fitment, or cause uneven stress distribution in the tube.<\/li>\n\n\n\n
- Decarburization: A defect involving the loss or reduction of carbon content from the surface of a steel tube, typically caused by heating or heat treatment processes. Decarburization can affect the tube’s hardness, strength, or resistance to wear and impact.<\/li>\n\n\n\n
- Weld Seam Discoloration: A defect characterized by changes in the color or appearance of the weld seam on a steel tube, often caused by improper welding parameters, inadequate shielding gas, or contamination. Weld seam discoloration can indicate potential weaknesses or reduced corrosion resistance in the affected area.<\/li>\n\n\n\n
- Hydrogen Embrittlement: A defect caused by the ingress of hydrogen atoms into the atomic structure of a steel tube, resulting in a loss of ductility and increased brittleness. Hydrogen embrittlement can occur during manufacturing processes or due to exposure to environments containing hydrogen, leading to the potential for sudden failure under stress.<\/li>\n\n\n\n
- Lack of Fusion: A defect in a welded steel tube where the molten metal fails to fuse properly with the base metal or adjacent weld passes, resulting in weak or incomplete joint formation. Lack of fusion can compromise the tube’s strength, integrity, and resistance to leakage or failure.<\/li>\n\n\n\n
- Overlapping Weld Bead: A defect occurring when the successive weld beads on a steel tube overlap or exceed the specified limits, leading to uneven surface profiles, increased stress concentrations, or reduced weld strength. Overlapping weld beads can affect the tube’s aesthetics, surface quality, or mechanical properties.<\/li>\n\n\n\n
- Undercut: A defect characterized by a groove or recess formed along the edge of a weld on a steel tube, typically caused by improper welding technique or excessive heat input. Undercuts can weaken the weld joint, promote stress concentration, or compromise the tube’s structural integrity.<\/li>\n\n\n\n
- Internal Corrosion: A defect involving the corrosion or deterioration of the internal surface of a steel tube, often caused by exposure to corrosive fluids, chemicals, or aggressive environments. Internal corrosion can lead to reduced wall thickness, loss of material strength, or potential leakage.<\/li>\n\n\n\n
- Straightness Deviation: A defect where a steel tube deviates from a straight line or exhibits excessive curvature along its length. Straightness deviation can affect the tube’s alignment, fitment, or compatibility with other components, requiring corrective measures for proper installation or assembly.<\/li>\n\n\n\n
- Segregation: A defect resulting from uneven distribution of alloying elements or impurities within a steel tube, leading to localized variations in composition or properties. Segregation can impact the tube’s mechanical properties, corrosion resistance, or overall performance in specific applications.<\/li>\n\n\n\n
- Quench Cracking: A defect occurring in heat-treated steel tubes, where rapid cooling during quenching causes the formation of cracks in the material. Quench cracking can lead to reduced strength, compromised structural integrity, or premature failure of the tube under load.<\/li>\n\n\n\n
- Surface Inclusions: A defect characterized by foreign substances or particles embedded in the surface of a steel tube, such as oxides, slag, or non-metallic impurities. Surface inclusions can affect the tube’s surface quality, corrosion resistance, or mechanical properties, depending on their size, nature, or distribution.<\/li>\n<\/ol>\n\n\n\n
