What does 316BA tube mean?

This post was last edited by leonnie on 2011-1-5 09:25. BA is short for bright annealing, which refers to the annealing process applied to 316 bright tubes

Just execute it right away? Is polishing required to meet the standards?

Product description for BA pipes: Production standards: GB (Chinese standard), ASTM (American standard), JIS (Japanese standard), DIN (German standard). Steel pipe materials: 304, 304L, 316, 316L, 316Ti, etc. Pipe standards: Metric (ISO), Imperial (Inch), Japanese standard (A). Pipe classifications: Pickled, mechanically polished, bright annealed, electropolished. Pipe specifications: Metric (ISO): Φ3mm~Φ630mm; Imperial (Inch): 1/8"~4". Processing methods: It goes through multiple processes of cold rolling and cold drawing, internal and external diameter sizing, bright annealing, and finally polishing to achieve the desired shape. Product precision: The tolerance range is kept below 0.02 mm, and the roughness of the inner and outer walls is below 0.4 um. Product packaging: Cleaned by chemical solvent washing, purged with nitrogen, sealed with caps at both ends, and packaged in a single-layer anti-static bag. Application areas: medical devices, food and beverage pipelines, purification equipment, high-purity gases, and other industries. Overview: The standard British imperial sizes are outer diameter: 1/8", 3/8", 1/4", 1/2", 1", 1.5", etc. Wall thickness: 0.035"～0.2". The standard dimensions in the metric system are an outer diameter of 3.17 mm, 9.53 mm, 6.35 mm, 12.7 mm, 25.4 mm, 38.1 mm, etc., with a wall thickness of 0.89 mm to 5 mm. Pressure resistance: 80–180 Mpa; materials: 304, 304L, 316, 316L, 316Ti, etc. Materials with special specifications can be customized according to the requirements of the client. The product meets technical standards such as ASTM A269—2002, JIS G4305, GB/T 12771—2000, and GB/T14976—2002. Through multiple cold rolling and cold drawing processes, internal and external sizing, inner wall polishing, bright annealing, and final polishing, it achieves a smooth interior and exterior surface, with precise manufacturing and high accuracy. It is cleaned by washing with chemical solvents, purged with nitrogen, sealed with caps at both ends, and packaged in a single-layer anti-static bag. It features high oil-repellent cleanliness, corrosion resistance, high temperature resistance, uniform wall thickness, and high smoothness of both the inner and outer surfaces. Superior and precise polishing technology ensures accurate dimensions; welding between pipe fittings is easy, assembly is rapid, and the wall thickness is consistent from one end of the pipe to the other. This allows for smooth product flow without any residues. Please feel free to point out any errors
