Stainless Steel Rectangular Pipes are commonly produced from austenitic grades like 304/304L and 316/316L, which provide a perfect combination of properties. For example, SS 304 has around 18-20% Chromium and 8-10.5% Nickel with good corrosion resistance, formability, and weldability. SS 316/316L increases corrosion resistance, especially to pitting and crevice corrosion, by the addition of 2-3% Molybdenum. Mechanically, these pipes have high tensile strengths ranging from 485-620 MPa (70-90 ksi) and yield strengths ranging from 170-205 MPa (25-30 ksi) for standard grades. They also have excellent ductility and impact toughness, which ensures structural integrity under different loads and conditions of the environment.

The company also conducts various tests to ensure the pipes are of high standard before being shipped out. Some of the tests include Hardness Test, Chemical Analysis via Spectro Analysis, Positive Material Identification (PMI)-Testing, Flattening Test, Micro & Macro Test, Pitting Resistance Test, Flaring Test, and Intergranular Corrosion (IGC)-Test among others. In addition, the documentation is very complete for full traceability and observance of industrial standards.
Yes, stainless steel rectangle pipes can be welded using appropriate welding techniques such as TIG or MIG welding. Proper preparation and filler material are essential for strong, durable welds.
Stainless steel rectangle pipes are highly resistant to corrosion due to their chromium content. However, they may corrode in harsh environments with high chloride exposure or inadequate maintenance.
Yes, stainless steel rectangle pipes can be used for natural gas applications due to their strength, corrosion resistance, and ability to withstand high pressure, ensuring safe and durable performance.
Stainless steel rectangle pipes made from austenitic grades (like 304 and 316) are generally non-magnetic. However, some ferritic or martensitic grades may exhibit magnetic properties.
Stainless Steel Rectangular Pipes are versatile in use and are commonly used in a variety of industries based on their high structural strength, beauty, and resistance to corrosion. They are widely utilized in construction and architectural applications in framing, support, handrails, balustrades, and ornamentation, providing a smooth and contemporary appearance. In manufacturing, they are used as essential parts for machinery frames, industrial machines, and conveying equipment. They are particularly suited for use in food processing, pharmaceutical, and medical equipment due to their cleanliness aspect.
