Seamless Pipes & Tubes
Seamless pipes and tubes have a smooth, uniform structure and superior strength, as they lack welded joints. Made through extrusion and hot rolling, they offer excellent durability and resistance to pressure and temperature.
Sun Mark’s seamless pipes and tubes are known for their corrosion resistance and precise finish. Widely used in industries like oil and gas, power plants, and automotive, they ensure reliable performance in critical environments.
