Product Description

Bright Annealed Tube / Pipe
Designed for critical and purity applications such as semiconductor manufacturing, Max Stainless Steel's high purity tubing delivery of gases, chemicals and solvents, 

or use in ultra High vacuum piping for reducing out gas rate.

From advanced manufacturing processes, including special cold drawing and cold pliger not just precision for sizes, 

but also enhance material substrutes density by cold pilger process. The ID is cold drawing to a 15Ra(0.4µm) finished, 

by Hydrogen bright annealed process removed tube lubrication and optimum anti-corrosion ability, stress free, 

good mechanical properties follow by precision cleaning process to removed any residual contaminants, 

simulated natural light inspection at both ends verifies cleaning before the tubes are nitrogen purged and capped.

Bright Annealing available in a wide range of stainless steels, are characterized by tight tolerances, 

and the inside surface of the tubes is free of oil, grease and other particles. This ensures, for example, 

an optimized and even flow of liquids and gases from the sensor to the measuring instrument. 

We have 4 Sets of three roller Precision Cold Rolling Machines using highly polished rollers 

in touch with the stainless steel surface and control the velocity of the pilger machine to ensure the smoothness and brightness. 

Selected the best quality stainless steel round bar, clean and smooth on outside surface and inside surface. 

Withstand high pressure,no deformation after cold bending, no crack and break after flattening and flaring etc.
