Bearing Pipes
Pipes designed for bearing loads, offering high strength and durability.
Seamless pipes are commonly used for low and medium pressure service in various applications.
Applications for heat exchange tubes, streaming tubes, low and medium pressure boiler water wall, economizer, reheater, superheater and steam pipeline.
Seamless pipes are widely used for fluid transport, including conveying liquids such as water, sewage, oil, and natural gas. They are utilized in projects involving fluid transmission over long distances .
Seamless pipes are used in hydraulic pillar service and hydraulic support applications. They provide the necessary strength and reliability for hydraulic systems .
Seamless pipes find applications in various industries, including nuclear devices, petrochemicals, shipbuilding, and more. They are utilized in environments that require high-quality pipes capable of withstanding pressure and temperature extremes.
