Sumer Metal Industries Private Limited manufactures premium Stainless Steel 904L condenser tubes — a super-austenitic alloy engineered for demanding heat-exchanger and condenser applications. Our 904L tubes are produced to tight tolerances using seamless and welded/tube mill processes (as per customer requirement), then inspected and finished to optimize surface quality for condenser service. 904L is chosen where superior resistance to pitting, crevice corrosion and reducing acids is needed, making it ideal for marine, chemical and refinery condenser duties.
As a manufacturer, supplier and exporter, Sumer Metal Industries supplies 904L condenser tubes in a broad range of sizes, wall thicknesses and surface finishes, and we export these tubes to markets including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and several regions across Africa. Shipments are supported with mill test certificates, third-party inspection on request, packaging suitable for long sea voyages, and logistics support to ensure safe arrival and easy customs clearance in target markets.
These Condenser tubes conform to international standards such as ASTM A213, ASTM B677, and ASME SA213. They are available in both seamless and welded forms, with outer diameters ranging from 6 mm to 1016 mm and wall thicknesses from 0.5 mm to 50 mm. Custom lengths and finishes such as annealed, pickled, or bright annealed are available to meet client-specific requirements.
Sumer Metal Industries exports SS 904L Condenser tubes worldwide, covering markets such as Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada, and regions across Africa. The company ensures compliance with international quality standards, providing seamless and welded tubes with consistent dimensions and performance reliability, earning the trust of global clients in the power and chemical sectors.

A1: 904L contains significantly higher nickel and molybdenum plus copper, offering superior resistance to sulfuric and other reducing acids and better chloride/pitting resistance than 316L — beneficial in aggressive condenser environments.
A2: For export we provide Mill Test Certificates (MTC / EN 10204 3.1 or 2.2 depending on request), packing list, commercial invoice, and third-party inspection reports if required by the buyer or project.
A3: Use targeted phrases in page title and H1 such as "904L condenser tubes", "Stainless Steel 904L tubes supplier", plus location/export keywords (e.g., "export to Oman, UAE, Saudi Arabia"). Include a short technical table (composition & sizes), buyer keywords (e.g., "seamless 904L tubes 1/2""), and at least one FAQ block (schema-marked) to improve SERP snippets.
