Dexin provides high-quality Schedule 40 seamless pipes, manufactured under strict quality control and fully compliant with international standards including ASTM, EN, and API. Our SCH 40 pipes are available with material certificates, inspection reports, and export documentation to meet global procurement needs.
SCH 40 Seamless Pipe refers to seamless steel pipes manufactured according to the Schedule 40 (SCH 40) wall thickness standard. SCH (Schedule) is a wall thickness classification number defined by the ASME pipe size standard, and 40 represents a widely adopted "standard wall thickness" grade. Seamless Pipe means the steel pipe is manufactured without welds. It's important to note that SCH 40 does not represent a fixed actual wall thickness value; the actual wall thickness corresponding to SCH 40 varies depending on the nominal pipe size (NPS). Due to its seamless structure, which results in more uniform stress distribution, Dexin's SCH 40 seamless steel pipes offer superior strength, pressure resistance, and reliability compared to welded steel pipes of the same grade. Therefore, they are widely used in fluid transportation, industrial piping, building structures, and energy and utility systems. With its excellent balance of performance and cost, SCH 40 Seamless Pipe has become one of the most commonly used and versatile seamless steel pipe specifications in the industrial sector.
