Sumer Metal Industries Private Limited manufactures high-quality Stainless Steel 309 Needle Tubes designed for demanding thermal and corrosive environments. As a vertically integrated manufacturer, Sumer Metal controls raw material selection, cold drawing and finishing processes to produce consistent tube geometry, smooth internal bore and tight dimensional tolerances — features essential for needle and fine-capillary applications. Their production emphasizes traceability and batch testing to meet customer specifications and export compliance.
These 309 needle tubes are aimed at markets where resistance to high-temperature oxidation and good formability are required — for example components in heating elements, flue-gas systems, catalysts, and some medical devices where elevated temperature exposure occurs. Sumer Metal exports these tubes widely, with regular shipments to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and multiple regions across Africa, ensuring export packing, documentation (CO, MTC) and logistic routing fit each destination’s requirements.
Production processes for Sumer’s 309 needle tubes include precision cold drawing, annealing where required, and multiple inspection stages (visual, dimensional, and where requested, chemical verification and mechanical testing). Surface finish options include bright-annealed and pickled finishes; secondary operations such as straightening, cutting-to-length, and end-finishing are available to supply ready-to-use tubes for assembly lines or OEM production.
Quality assurance at Sumer Metal includes offering material test certificates (MTC), third-party inspection on request, and packing tailored for long-distance shipment. They emphasize compliance with international standards and customer drawings, and can provide lot-wise chemical analysis and hardness/tensile test reports. For buyers in regulated markets (medical or aerospace-adjacent applications), Sumer can discuss additional documentation and validation steps required.
