At Eramets Steel Alloys Pvt Ltd, we manufacture and supply premium quality Super Duplex Steel Pipes & Tubes in seamless and welded forms. Our products are produced in accordance with international standards such as ASTM, ASME, and EN specifications. These pipes feature precise dimensions, smooth surface finish, and high mechanical strength, making them suitable for critical industrial applications that demand long service life and reliability.
The Duplex Steel Pipes & Tubes we supply are widely used in oil and gas pipelines, petrochemical plants, heat exchangers, pressure vessels, desalination plants, and marine structures. Their high load-bearing capacity and resistance to seawater corrosion make them ideal for offshore platforms and shipbuilding industries. These pipes are also preferred for structural and mechanical applications due to their superior fatigue strength and low maintenance requirements.
We offer Duplex Steel Pipes & Tubes in various sizes, wall thicknesses, and schedules, including customized specifications as per client drawings and project needs. All products undergo strict quality testing such as hydro test, PMI test, ultrasonic test, and chemical & mechanical analysis. With competitive pricing, timely delivery, and complete mill test certificates (MTC), Eramets Steel Alloys Pvt Ltd stands as a trusted manufacturer and supplier of Duplex Steel Pipes & Tubes in Mumbai and across India.
We supply SS 304 round pipes, square pipes, and rectangular tubes for construction, fabrication, and machine systems. These DIN 1.4301 and UNS S30400 pipes fit complex layouts and tight spaces with ease. The low carbon composition improves weld strength and reduces cracking during setup. Builders trust these stainless steel 304 structural pipes for long service life.
Our SS 304 ERW pipes and tubes use high and low frequency resistance welding methods to create strong joints and smooth edges. Modern machines control wall thickness and surface finish with high accuracy. Each pipe passes tests for size, pressure, and surface quality before packing. Customers can order custom lengths, wall thicknesses, and finishes based on project needs.
Industries use stainless steel 304 pipes and tubes in food processing plants, chemical units, water supply lines, gas pipelines, and home appliances. These pipes stay clean, durable, and safe for daily operation. Clients value fair pricing, steady stock, and timely delivery from a trusted SS 304 pipes supplier and exporter.
