LONGYU EN 2.4617 304 316 Stainless Steel Seamless Pipe China High Cleanliness Bright Annealed Stainless Steel Tubing For Hydraulic Equipment
What is Electropolished Tubing?
Electropolish Stainless steel is the result of reverse plating, and an electrochemical solution is used to strip away the outer skin of the metal. LONGYU is a prominent manufacturer, stockiest, supplier, and distributor of Stainless Steel Electropolished Pipes & Tubes. Electropolished Stainless Steel Tubing is used for biotechnology, semiconductor, and pharmaceutical applications. The finishing of electroplating has different standards for use in other applications. These applications require a medium range of finish. Electro Polishing is a process that removes the absolute roughness of any metal in an electropolishing plant. This process makes the pipes more accurate in dimensions, and the Ep Pipe can be installed with accuracy in sensitive systems like pharmaceutical industrial applications. Different materials could be electropolished, enabling the Electro-Polished SS Pipes to retain minor contaminants on the surface. These pipes are available in various sizes ranging from 6NB to 1200NB and outer diameters from 1/8" to 12" NPS with thicknesses of 0.6mm to 12.7 mm.
What is Bright Annealed Polished Tube?
Bright Annealed Stainless Steel Tube is a type of tubing made from high-quality stainless steel that has undergone a bright annealing process. The bright annealing process involves heating the stainless steel tube to a high enough temperature to induce recrystallization and remove any residual stress, but below the temperature that would cause any significant oxidation or scaling. Bright Annealed Stainless Steel Tube is a tube with a bright, shiny surface finish and improved ductility and corrosion resistance. This makes bright annealed stainless steel tubes ideal for use in high-precision applications, such as in the pharmaceutical, semiconductor, and biotechnology industries.
