Description
Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of 316 Grade Size 1.5mm Thickness Stainless Steel Pipe in China. With abundant experience, we warmly welcome you to wholesale customized 316 Grade Size 1.5mm Thickness Stainless Steel Pipe from our factory. For price consultation, contact us.
With 18 years of stainless steel export experience and customers across more than 60 countries and regions, GNEE understands that buyers of 316 1.5mm stainless steel pipes are concerned not only about price, but also about material authenticity, dimensional accuracy, surface quality, delivery reliability, and long-term performance. Backed by ISO 9001-certified quality management systems and a stable global supply chain, we offer both stock availability and customized production services, helping customers shorten procurement cycles and reduce project risks.
When sourcing 316 1.5mm stainless steel pipes, material authenticity is one of the most critical considerations. Every batch of our products is manufactured using qualified raw materials and can be supplied with Mill Test Certificates (MTC), Positive Material Identification (PMI) reports, and third-party inspection documents upon request. This ensures that our pipes deliver consistent corrosion resistance, excellent weldability, and long service life in demanding environments.
Dimensional accuracy is another key factor, particularly for 316 stainless steel pipes with a 1.5mm wall thickness, which fall into the medium-thin wall category. Customers are often concerned about uneven wall thickness, oversized outside diameters, and poor fit-up during installation. To address these concerns, we implement strict process control and online dimensional inspection throughout the manufacturing process. Our standard production tolerance can be controlled within OD ±0.10mm and WT ±10%, while tighter tolerances are available for precision applications. In addition, we carefully control tube end roundness to ensure smooth welding, accurate connections, and reliable assembly, helping customers reduce installation difficulties and labor costs on site.
Surface quality directly affects both appearance and corrosion resistance. All 316 stainless steel pipes undergo comprehensive surface inspection before shipment. Through advanced polishing, pickling, and passivation processes, the tube surface remains clean and smooth, free from scratches, pits, scale, oil contamination, and welding defects. For polished 316 stainless steel tubes, the surface roughness can reach Ra ≤ 0.8μm or even lower, meeting the stringent requirements of food processing, pharmaceutical, sanitary, and high-purity industrial applications.

What are the standard tolerances for your 19mm OD x 1.5mm WT SS 316 pipes?
Unless otherwise specified, we follow ASTM A269 standards. This typically means: outer diameter tolerance: ± 0.13 mm, wall thickness tolerance: ± 10%, straightness: ≤ 1.5 mm/meter. We can also provide tighter tolerances upon customer request (e.g., ASTM A312 or customer-specific standards), but this may affect delivery time and price.
What are the typical applications for 1.5mm WT SS 316 pipes?
Medical Equipment: Components requiring high hygiene and corrosion resistance.
Food & Beverage Industry: Sanitary piping, processing lines.
Pharmaceuticals: Drug manufacturing and processing.
Marine & Offshore: Handrails, structural components, fluid lines exposed to saltwater.
Chemical Processing: Piping for corrosive fluids.
High-end Architecture & Decorative: Balustrades, interior design elements.
Stainless Steel 316 Pipe price per kg

We have a dedicated channel for urgent orders. If your project has a tight schedule, we can prioritize the drawing/finishing stage, shortening the delivery time by 5 days.
We will provide weekly progress reports, including photos of the production and packaging stages, allowing you to track your order in real time. Because 1.5mm is a precision thickness, all tubing will be individually bagged, with plastic caps on the pipe ends, and secured in reinforced wooden crates to prevent damage during sea transport.
