INTRODUCTION

Steel tubes are like long, strong pipes made of steel, which is a very tough metal. These pipes can be big or small, thin or thick, and they have many uses like building things, plumbing, making stuff in factories, and even in vehicles. They are great because they're strong and don't easily get damaged by things like rust.

To ensure the product quality of steel tubes, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.

IS 1161: 2014 covers steel tubes for structural purposes. This standard specifies the requirements for hot-finished welded (HFW), hot finished seamless (IFS), electric resistance welded (ERW), or high-frequency induction welded (HRIW) and plain carbon steel tubes for structural purposes.

REQUIREMENTS FOR IS 1161:2014  

1.     Steel tubes covered by this standard must be designated by their nominal bore and classified as 'Light,' 'Medium,' or 'Heavy,' depending on the wall thickness.

2.     Depending on the yield stress of the material, they will be graded as Y St 2 10, Y St 240, and Y St 3 10. As a result, the designation of steel tubes must include the nominal bore of the tube, wall thickness classification, and material grade.

3.     General requirements for the supply of steel tubes for structural purposes must conform to IS 1387.
