BA Grade Silicon Coated Stainless Steel Coil Tubing
Introduction
BA Grade Silicon Coated Stainless Steel Coil Tubing provides a superior solution. The bright annealed stainless steel is coated on both the inner and outer surfaces with a high-purity silicon layer, giving it:
Outstanding resistance against acids, alkalis, and corrosive gases
Ultra-smooth, non-adsorptive surfaces that minimize contamination
Long-lasting durability and easy cleaning, even in harsh environments
At Huaxiao-Alloy, we manufacture and supply BA grade silicon coated stainless steel tubing that meets the stringent demands of petrochemical, semiconductor, and medical industries worldwide.
In industries where purity, corrosion resistance, and cleanliness are critical, conventional stainless steel tubing often fails to meet the highest requirements. Adsorption of impurities, corrosion in aggressive chemicals, and difficulties in cleaning can compromise both process reliability and product quality.
1. Why BA Grade Silicon Coated Tubing?
The Limitations of Conventional Stainless Steel Tubing
Adsorption of Impurities: Gases and liquids (e.g., hydrogen chloride, formic acid, acetic acid) easily react with steel surfaces.
Surface Cracking: Repeated cleaning and exposure to chemicals lead to micro-cracks and pitting.
Residual Contamination: Impurities and byproducts are difficult to remove, affecting analytical accuracy.
2. The BA Silicon Coated Solution
Silicon Protective Layer – Creates a stable, chemically inert barrier
Bright Annealed Finish – Provides a mirror-smooth surface with minimal defects
Anti-Adhesion Properties – Prevents residue build-up and facilitates easy cleaning
High Corrosion Resistance – Withstands strong acids and oxidizing agents
Extended Service Life – Reduces downtime, cleaning cycles, and replacement costs
