- Stainless Steel Welded Tube
Neeka Tubes provides high-quality SS welded tubes. As a reliable supplier of Stainless Steel Welded Tubing, we make tubes using materials that follow both international and national standards. Our team uses advanced techniques to manufacture stainless steel welded tubes. These tubes are built to last and perform well. We make the tubes by rolling stainless steel sheets and welding the seam. This process creates strong tubes that are used in many industries.
Our stainless steel welded tubing is manufactured using advanced techniques such as TIG welding, laser welding and high-frequency welding, ensuring seamless construction, and superior strength. The tubes undergo annealing, pickling and passivation to enhance their mechanical properties and corrosion resistance. We offer these tubes in various sizes and thicknesses customized to meet industrial requirements. Our products meet with ASTM and ASME standards, including A269, A249, SA269 and SA249. Available in grades such as 304, 304L, 316 and more our welded tubes are designed for excellent performance in critical applications.

Features of Stainless Steel Welded Tubing
- Strong Strength & Durability: Stainless steel welded tubing has a high yield and tensile strength which means it can handle mechanical stress, vibration and pressure without bending. Its strong structure makes sure that it will last a long time even in tough industrial settings.
- Corrosion and Heat Protection: The chromium-rich composition forms a passive oxide layer that resists oxidation, chemical attack and moisture exposure.The protective layer also enables the tubing to maintain stability and performance under elevated temperatures.
- Density and Melting Point: Welded stainless steel tubing has a balanced density that makes it strong without being too heavy. Its high melting point makes sure that it stays the same size and is safe to use in high-temperature processing or thermal applications.
- Smooth Surface and Precise Measurements: The welded manufacturing process delivers uniform wall thickness, accurate dimensions and a clean surface finish.This precision supports efficient fluid flow, easy fabrication and consistent fit during installation.
- Cost Effective & Sustainable: Welded tubing is more reasonable than seamless tubing that still works well. It is a good choice for long term industrial use because it can be recycled and doesn’t need much maintenance.
Our stainless steel welded tubes are widely used in petrochemical, chemical, oil & gas, refinery, fertilizer, automotive, power, structural and mechanical industries. These tubes are essential for heat exchangers, condensers, fluid transportation and high-pressure applications due to their excellent resistance to harsh environments. We provide many grades thicknesses and sizes to meet the exact needs of our customers. This way we ensure the best results in all applications.

SS Welded Tubing Packing & Marking
Our team packs the welded tubes in wooden boxes, plastic-capped ends and waterproof covers to protect the tubes during transit and ensure safe packaging.
We mark each tube with grade, size, standard, heat number, and the manufacturer’s name so that the tubes can be identified and traced easily. Our efficient supply chain and global logistics support help us ensure timely deliveries worldwide. This is the reason we are able to provide high-quality products in excellent condition.
Quality Tests & Certifications
We believe in quality. Our SS welded tube goes through vigorous testing like hydrostatic testing, eddy current testing, ultrasonic testing, PMI (Positive Material Identification) and mechanical testing. The tubes are certified to Mill Test Certificates (MTC), EN 10204 3.1 certification and third-party inspection reports to ensure compliance with industry standards and customer specifications.
