Products Description
SS 321/321H Pipes & Tubes find applications in various industries, including pharmaceutical equipment, pharmaceutical industry, seawater equipment, chemical equipment, specialty chemical industry, gas processing, petrochemical industry, power generation industry, heat exchangers, condensers, paper industry, offshore oil drilling industry, and pulp industry.These pipes and tubes are particularly suitable for use in flues and spiral welded pipes. They can withstand annealed temperatures without deformation. The addition of titanium during production enhances the pipes' resistance to carbide precipitation and increases their hardness.SS 321/321H Tubes are highly regarded for their non-corrosive nature, making them suitable for use in aerospace equipment and various storage units. They possess exceptional qualities such as high strength, tensile strength, ductility, durability, flexibility, and formability.After production, these pipes undergo several tests to ensure their quality and reliability. These tests include flaring tests, mechanical tests, chemical tests, hardness tests, hydrostatic tests, macro tests, micro tests, radiography tests, PMI (Positive Material Identification) tests, and flattening tests.By subjecting SS 321/321H Pipes & Tubes to these rigorous tests, their performance and compliance with industry standards are verified. This ensures that the pipes and tubes meet the required quality specifications and can be relied upon for their intended applications.Stainless Steel 321 Pipes Exporter, SS ASTM A312 TP321H Seamless Pipes, ASTM A358 Stainless Steel 321H EFW Pipe Supplier, ASTM A213 Stainless Steel 321 Tubes, SS 321 Tubing , SS 321 Welded Tube
