TP316L Bright Annealed Seamless Stainless Steel Tube 3/4'' X
0.065'' X 20FT, ASTM A269
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.
