Types of Stainless Steel Pipe and Tube
Seamless 316 Stainless Steel Tubing
Our Seamless 316 stainless steel tubing offer superior performance in highly corrosive environments. As molybdenum-enhanced austenitic stainless steel pipes, they provide exceptional resistance to chlorides and acidic conditions, making them ideal for marine, chemical, and pharmaceutical applications.
201 Stainless Steel Pipe
201 stainless steel pipes are a versatile and economical alternative to traditional 304 stainless steel, offering excellent corrosion resistance, formability, and strength. Ideal for a wide range of industrial, architectural, and domestic applications, these pipes provide outstanding value without compromising on performance.
904L Stainless Steel Tubing
Our 904L Stainless Steel Tubing is a high-alloy, super-austenitic stainless steel with an extremely low carbon content (≤0.02%) and high proportions of chromium (19%-23%) and nickel (23%-28%), resulting in excellent corrosion resistance.

Surface Treatment of Stainless Steel Pipe and Tube
Grinding and polishing
Grinding is the process of removing surface imperfections using abrasive tools. It provides a uniform finish but can lead to scratches. Polishing follows grinding, using finer abrasives to create a smoother surface. This treatment not only improves the appearance but also enhances corrosion resistance by reducing surface roughness. It is often used when a decorative finish is required, like in architectural applications.
Brushing
Brushing gives stainless steel a distinctive matte finish with fine parallel lines. It's achieved using an abrasive belt or wire brush. This finish is popular for its modern look; however, it's essential to note that brushed stainless steel can be more prone to showing scratches. If used outdoors, additional protective measures may be necessary to prevent corrosion over time.
Buffing
Buffing uses a soft cloth wheel and polishing compounds to produce a highly reflective, mirror-like surface. While buffed stainless steel is stunning and often used for decorative purposes, it requires regular maintenance to retain its shine and may be more susceptible to fingerprints and smudges.
