SS 316Ti Seamless Pipe Weight Chart
The weight of Stainless Steel 316Ti Seamless Pipe depends mainly on its outside diameter, wall thickness, pipe length and material density. Heavier schedules have greater wall thickness and therefore higher weight per metre.
| Pipe Size | Schedule | Approx. Wall Thickness | Approx. Weight |
|---|---|---|---|
| 1 Inch | SCH 40S | 3.38 mm | Approx. 2.5 kg/m |
| 2 Inch | SCH 40S | 3.91 mm | Approx. 5.5 kg/m |
| 3 Inch | SCH 40S | 5.49 mm | Approx. 10.3 kg/m |
| 4 Inch | SCH 40S | 6.02 mm | Approx. 14.6 kg/m |
The values shown are indicative. Actual pipe weight may vary according to dimensional tolerances, manufacturing requirements and the applicable dimensional standard.

ASTM A312 TP316Ti Seamless Pipe
ASTM A312 TP316Ti Seamless Pipe is manufactured from Type 316Ti stainless steel for applications requiring corrosion resistance and suitable performance in elevated-temperature environments. The specification covers seamless, welded and heavily cold-worked austenitic stainless steel pipe intended for general corrosive service and high-temperature applications.
Stainless Steel 316Ti Seamless Pipes can also be supplied to the corresponding ASME requirements where specified by the applicable project or engineering code. The required grade, dimensions, heat treatment, testing and certification should be confirmed before procurement.
SS 316Ti Seamless Pipe Chemical Composition & Mechanical Properties
Stainless Steel 316Ti is an austenitic chromium-nickel-molybdenum stainless steel with titanium stabilization. Its composition is designed to provide corrosion resistance while maintaining useful mechanical properties under demanding service conditions.
| Element | Typical / Maximum Requirement |
|---|---|
| Chromium | Approx. 16.0–18.0% |
| Nickel | Approx. 10.0–14.0% |
| Molybdenum | Approx. 2.0–3.0% |
| Carbon | Maximum 0.08% |
| Manganese | Maximum 2.00% |
| Silicon | Maximum 1.00% |
| Titanium | Specified for stabilization |
Mechanical properties such as tensile strength, yield strength and elongation depend on the applicable product specification and material condition. Testing and acceptance requirements should therefore be confirmed against the specified standard and purchase requirements.
SS 316Ti Seamless Pipe vs Welded Pipe
Both seamless and welded Stainless Steel 316Ti Pipes can be used in industrial applications, but their manufacturing processes are different. Seamless pipes are produced from a solid billet without a longitudinal weld seam, whereas welded pipes are formed from stainless steel plate or strip and joined along the seam.
| Feature | SS 316Ti Seamless Pipe | SS 316Ti Welded Pipe |
|---|---|---|
| Manufacturing | Produced without a longitudinal weld | Produced by forming and welding strip or plate |
| Wall Thickness | Suitable for a wide range of wall thicknesses | Available in various wall thicknesses |
| Typical Selection | Selected for specified pressure and demanding services | Often selected for larger diameters and fabrication requirements |
| Cost | Generally higher depending on size and specification | Can be more economical for suitable applications |
The choice between seamless and welded pipe should be based on the applicable specification, diameter, wall thickness, operating conditions, fabrication requirements and project design criteria.

Frequently Asked Questions
Stainless Steel 316Ti Seamless Pipes are titanium-stabilized austenitic stainless steel pipes manufactured without a welded seam. They offer excellent corrosion resistance, superior weldability and enhanced performance in elevated-temperature applications.
SS 316Ti contains titanium, which stabilizes the material and reduces the risk of intergranular corrosion after welding or prolonged exposure to high temperatures. Standard SS 316 does not contain this titanium addition.
Titanium combines with carbon to prevent chromium carbide precipitation during welding and heat exposure. This improves resistance to sensitization and intergranular corrosion while enhancing high-temperature performance.
ASTM A312 TP316Ti covers seamless, welded, and heavily cold-worked austenitic stainless steel pipes intended for high-temperature and corrosive service applications.
Stainless Steel 316Ti is designated as UNS S31635 and Werkstoff Number (WNR) 1.4571. It is also commonly identified by the EN grade X6CrNiMoTi17-12-2.
SS 316Ti Seamless Pipes are widely used in petrochemical plants, chemical processing industries, power generation facilities, heat exchangers, marine applications, offshore platforms, pharmaceutical plants and food processing industries.
Seamless pipes have no welded joints, providing better structural integrity, uniform strength, and improved pressure resistance. This makes them ideal for critical high-pressure and high-temperature applications.
SS 316Ti Seamless Pipes offer excellent oxidation resistance, creep strength and structural stability at elevated temperatures, making them suitable for long-term high-temperature service conditions.
Yes. The molybdenum content in SS 316Ti provides excellent resistance to pitting and crevice corrosion in chloride-containing environments, making these pipes suitable for marine and offshore applications.
