⚖️ MS Pipe Types Based on Manufacturing

1. MS ERW Pipe
   • ERW = Electric Resistance Welded
   • Ideal for low to medium pressure applications
   • Common in construction and structural use
2. MS Seamless Pipe
   • No welding seam; better pressure tolerance
   • Used in oil, gas, and high-pressure environments
3. MS Square & Rectangular Pipes
   • For aesthetic and structural applications
   • Common in railings, gates, and modular constructions
