Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of Stainless Steel 309 Condenser Tubes, catering to industries that demand high-performance materials for extreme service conditions. Our SS 309 Condenser tubes are designed to offer exceptional strength, corrosion resistance, and durability, making them suitable for applications in power plants, refineries, petrochemical plants, and industrial Condenser s.
Stainless Steel 309 is an austenitic chromium-nickel stainless steel known for its excellent resistance to oxidation and scaling at elevated temperatures. This grade is specifically developed for high-temperature service and retains its strength and toughness even after prolonged exposure to heat. The low carbon version, 309S, offers improved weldability and minimizes the risk of carbide precipitation during welding operations.
As an established supplier, Sumer Metal Industries provides SS 309 Condenser Tubes in seamless and welded forms. The tubes are manufactured in compliance with international standards such as ASTM, ASME, and EN specifications. We ensure precise dimensional tolerances, superior surface finish, and consistent metallurgical properties to meet stringent client requirements.
We have a strong export network covering Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and several regions across Africa. Our global clientele relies on us for timely deliveries, certified products, and competitive pricing. Every shipment is packed with export-worthy packaging to ensure safe transportation by sea, land, or air.

❓ Frequently Asked Questions (FAQs)
Q1: What is Stainless Steel 309 and why is it used for condenser tubes?
A1: Stainless Steel 309 is an austenitic chromium-nickel alloy with high chromium (≈22–24%) and nickel (≈12–15%) content. It resists oxidation and retains strength at elevated temperatures, making it suitable for condensers and heat exchangers exposed to high-temperature gases or cyclical heating.
Q2: What specifications and documentation are provided with exported SS 309 tubes?
A2: Sumer Metal Industries supplies material test certificates (EN 10204 3.1 or equivalent), dimensional inspection reports and optional NDT reports. Tubes can be supplied to ASTM/ASME or EN standards per contract (e.g., ASTM A213/A312/A269, EN 1.4828 equivalents).
Q3: Are custom sizes and end finishes available for export orders?
A3: Yes — we offer custom diameters, wall thicknesses, cut-to-length, bevelling and end-finishing. Please provide drawings or specifications with your enquiry so we can quote packaging, lead time and testing requirements.
