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.

STAINLESS STEEL ELECTROPOLISHED PIPES & TUBES

The seamless pipes are dimensionally accurate and can have less absolute roughness. Electropolishing works when the application is susceptible and needs the inside of the pipe to be as clean and smooth as possible. This procedure is carried out by electrolysis in, where the product loses atom by atom on the surface and comes to a polished finish. However, the process has its downfalls as well. Even with this method, the absolute roughness persists to some extent. These tubes and pipes are used in various applications such as dairy production, brewery, food industry, pharmacy, cosmetics, chemical industry, and more. These pipes and tubes are known for better corrosion, good flow characteristics, improved hygiene, and smooth finish.

Electropolished (EP) Tubing

For applications with surface finish requirements well beyond the quality realized in a standard mill finish, we maintain an inventory of electropolished stainless steel tubing in diameters ranging from 1/8" through 1". Through submersion in an electrically charged electrolyte solution bath, a smooth uniform surface is created by dissolving imperfections. This process removes any contamination on or just below the tube's surface and passivates it, bolstering the corrosion resistance of the steel. EP stainless steel tubing is typically used in the following applications:

Sample lines for H2S in chemical processing
Semiconductor fabrication
Sanitary piping systems
Pharmaceutical manufacturing

The precision bright tube is one of high-precision steel pipe made of fine-drawn or cold-roled. The precision bright tube has the following advantages: no oxidation level on the inside/outside wall, without leakage withstand high pressure, high precision, high degree of finish, no deformation, faring while bending, and flattening without cracks. they are mainly used in the production of pneumatic or hydraulic components, such as cylinders or oil cylinders which can be seamless or welded tubes. chemical components of the precision bright tube have carbon c, silicon si, manganese Mn, sulfur s, phosphorus P, and chromium Cr.

A spectrometer will test each lot of raw materials before being put into storage. We wll100% PMl the mother pipe to ensure we put the right material. We will 100 %PMl the finished pipe again to ensure we produce the right grade. This is the way we ensure the chemical quality.
We are using the advanced cold-drawn technology from Japan and Korea, making the close dimension controls.
