Description
It seems like you’re looking for a detailed overview of IS 1161 ERW Pipe specifications and properties, particularly regarding the different grades such as YST 210, YST 310, and YST 355. Here’s a more concise breakdown of the critical sections based on your input:
IS 1161 Material Specification
IS 1161 specifies electric resistance welded (ERW) carbon steel pipes, with grades like YST 210, YST 310, and YST 355, categorized by their minimum yield strengths of 210 MPa, 310 MPa, and 355 MPa, respectively. The pipes are available in various diameters and thicknesses and are used for structural and mechanical applications.
IS 1161 ERW Pipe Types
- YST 210, 310, 355 Seamless and Welded Pipes: These are used in applications like columns, structural supports, and slurry lines.
- Various Types: Seamless pipes, welded pipes, boiler tubes, and different sized pipes (e.g., 5-inch, 9-inch, etc.).
Thickness and Size Range
- Seamless Pipes: Range from 4mm to 219mm in diameter.
- Welded Pipes: Range from 5mm to 1219.2mm in diameter.
- Wall Thickness: Ranges from 0.5mm to 20mm, covering different schedules such as SCH 20 to XXS.
Properties of IS 1161 YST 210/310/355 Pipes
- Chemical Composition:
- YST 210: C – 0.12%, Mn – 0.60%, P – 0.040%, S – 0.040%
- YST 310: C – 0.25%, Mn – 1.30%, P – 0.040%, S – 0.040%
