Sumer Metal Industries Private Limited manufactures premium Stainless Steel 316 Needle Tubes engineered for demanding medical, pharmaceutical, instrumentation and precision-engineering applications. Their 316 needle tubes are produced using tightly controlled cold-drawing and finishing processes to deliver consistent outer diameters, smooth inner surfaces and excellent dimensional tolerance — qualities essential for needles, cannulas, hypodermic assemblies and micro-fluidic components. The company’s production emphasizes traceability, batch testing and certification to meet export buyers’ quality expectations.
As a global manufacturer, Sumer Metal Industries exports 316 needle tubes to markets including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and multiple regions across Africa. Their export service includes customs documentation, supply of mill certificates (EN 10204 / 3.1 where required), packaging for long-distance transport, and the option for surface passivation or electropolishing to meet client specifications in regulated industries.
Stainless Steel 316 is selected for needle tubes when higher corrosion resistance is needed compared with 304 — chiefly because of its added molybdenum content which improves resistance to chloride stress-corrosion cracking and crevice corrosion. Sumer Metal’s 316 tubes are suitable for saline environments, some chemical processing lines, coastal installations, and most medical environments where sterilization and cleaning are frequent. For applications requiring the lowest carbon content, they also offer 316L variants on request.
Quality & testing: each production batch undergoes dimensional inspection (OD/ID/wall thickness), surface finish checks, microstructure verification (on request), and chemical analysis to confirm composition. Typical finishing options include bright annealed, pickled & passivated, electropolished ID/OD, and custom surface roughness targets. The company can supply third-party inspection and testing (e.g., PMI / OES chemical test reports) for international buyers.

❓ Frequently Asked Questions (FAQs)
Q1: What makes SS316 needle tubes better than SS304 for medical use?
A1: SS316 contains molybdenum which improves resistance to chloride corrosion and stress-corrosion cracking, making it more suitable than SS304 for saline environments, some sterilization processes and applications exposed to chlorides.
Q2: Can Sumer Metal supply electropolished or passivated 316 needle tubes for pharmaceutical applications?
A2: Yes — the company offers electropolishing, passivation and controlled surface-roughness finishes to meet cleanliness and surface criteria commonly required by pharma and medical device manufacturers. Specify finish requirements when ordering.
Q3: What specifications and documentation are provided for export orders?
A3: Sumer Metal typically supplies mill/test certificates (EN 10204 / 3.1 on request), dimensional inspection reports, and packaging suitable for export. Third-party inspection and PMI/OES chemical analysis can be arranged for international customers.
