Pipe Schedule 5S to 160 – SS Pipe Chart by Udhhyog
If you're working with stainless steel pipes in industrial, plumbing, or structural projects, understanding the pipe schedule is critical. Pipe schedules define the wall thickness of a pipe, which impacts its pressure handling capacity, weight, and material cost.
In this complete guide from Udhhyog, we cover all schedules from 5S to 160, including a SS pipe size and thickness chart, along with technical notes to help you choose the right grade and size for your project.
📌 What Is Pipe Schedule?
Pipe Schedule (SCH) is a standard used to specify the wall thickness of pipes based on the Nominal Bore (NB) or Nominal Pipe Size (NPS). It impacts:
-
💪 Pressure capacity
-
⚖️ Weight per meter
-
💰 Cost of the pipe
🔍 What Does "S" Mean in Schedule 5S, 10S, etc.?
The “S” in schedules like 5S, 10S, 40S refers to "Stainless", denoting a thinner wall version of the standard carbon steel schedules. These are commonly used in stainless steel pipe standards such as ASTM A312.

📚 FAQs – Pipe Schedule 5S to 160 for SS Pipes
❓1. What is the main difference between Schedule 40S and 40?
Both have similar wall thickness, but 40S is specific to stainless steel, while Schedule 40 can be for carbon steel or stainless. Always refer to ASTM B36.19M for stainless pipe schedules.
❓2. Can Schedule 5S SS pipes be used for plumbing?
Yes, Schedule 5S is commonly used in low-pressure water supply lines, decorative pipelines, and food-grade installations.
❓3. How do I select the correct pipe schedule for my application?
You should consider pressure, fluid type, temperature, and installation location. Contact Udhhyog for professional advice tailored to your project.
❓4. Are all pipe schedules available in seamless and welded types?
Yes. At Udhhyog, all schedules from 5S to 160 are available in:
-
Seamless pipes for high-pressure applications
-
ERW/welded pipes for general use
❓5. Is there a price difference between Schedule 10S and Schedule 40S pipes?
Absolutely. As wall thickness increases, so does the weight and material cost. Schedule 40S is costlier than 10S for the same OD.
❓6. Do you supply SS pipes in mirror finish for 10S and 40S?
Yes. Udhhyog offers mirror-polished stainless steel pipes in various schedules for architectural and sanitary piping applications.
❓7. What is the weight difference between Schedule 10S and 160?
A Schedule 160 pipe can be 2–3x heavier than a 10S pipe of the same size, due to increased wall thickness. Udhhyog provides detailed weight charts for accurate estimation.
❓8. Are pipe schedules standardized internationally?
Yes. Pipe schedules like 10S, 40S, 80S are standardized in ASME B36.19M and widely used across industries worldwide.
❓9. Can I get project-specific testing done on SS pipes?
Yes. Udhhyog arranges third-party inspections, hydrotesting, PMI testing, and custom certification based on project demands.
❓10. How fast can I get Schedule 40S SS pipes in 50mm?
If in stock, dispatch is within 24–48 hours. For bulk or polished pipes, delivery depends on location and finishing time — typically 3–7 days PAN India.
