GI Seamless Pipe
GI Seamless Pipe: Sizes, Specifications & HSN Code
GI seamless pipes are galvanized iron pipes made without any welding joints, making them ideal for high-pressure and corrosion-prone environments. At Udhhyog, we supply standard and custom sizes of seamless GI pipe including 40mm, 80mm, and other nominal bore (NB) specifications. These are commonly used in gas, oil, water transmission, and fire protection systems.
What is a GI Seamless Pipe?
A seamless GI pipe is manufactured through a hot extrusion process without welding seams, and then galvanized to add a protective zinc coating. This provides both strength and corrosion resistance, especially important in fluid handling systems that require uninterrupted internal flow.
Key Features of Seamless GI Pipes
- Uniform strength and internal pressure resistance
- Longer lifespan due to anti-corrosive galvanized layer
- Minimal maintenance and leak-free design
- Available in S&S (Socket & Spigot) or plain end finishes
Common GI Seamless Pipe Sizes
- GI pipe S&S seamless NB 40mm – Common for structural and fluid distribution
- GI pipe seamless 80mm – For industrial plumbing and fire-fighting systems
- Other NB sizes and schedules available on request
Do Seamless GI Pipes Come with Thread?
Yes, many seamless GI pipes are available with threading upon request. Threaded ends are typically used in plumbing, fire suppression, and oil & gas applications. However, pipes can also be supplied in S&S (Socket & Spigot) form or plain ends, depending on client requirements.
HSN Code for GI Seamless Pipe
The general HSN code for seamless GI pipes is 730419. It is recommended to consult your tax advisor for GST classification based on exact specification and end use.
Applications of GI Seamless Pipes
- Fire sprinkler and protection systems
- High-pressure water and steam transmission
- Gas supply and air compressor lines
- Structural and fabrication frameworks
