Working Principle:

Stainless steel pipes function as conduits for transporting fluids, gases, or solids under various operating conditions. Their working principle is based on providing a smooth, durable, and corrosion-resistant passage, ensuring that the medium flows efficiently without contamination or leakage.

• Seamless Pipes: Manufactured from solid billets, seamless pipes provide uniform strength across the entire cross-section, making them ideal for high-pressure and high-temperature applications.

• Welded Pipes: Produced by rolling and welding stainless steel plates or strips, welded pipes offer cost-effective solutions for large diameters and low-to-medium pressure systems.

• Surface Treatments (Polished / Pickled, Annealed): These processes enhance corrosion resistance, mechanical strength, and cleanliness, ensuring pipes meet hygienic, structural, or industrial requirements.
