The LEOCO Carbon Steel 90° Elbow is a butt-weld pipe fitting manufactured to ASME B16.9 for changing pipeline direction through a right angle. Available in both long-radius (1.5D) and short-radius (1D) patterns, it is forged and seamless or welded from certified carbon steel and supplied with a full material test certificate.
Every elbow is dimensionally verified to ASME B16.9, bevelled for butt welding to ASME B16.25, and pressure-rated to match the connecting pipe schedule. Standard supply is ASTM A234 WPB carbon steel; low-temperature A420 WPL6 and stainless A403 grades are available on request for cryogenic and corrosive service.
Wall thickness is matched to the specified pipe schedule (SCH 10 through SCH 160, STD/XS/XXS). Each fitting is 100% visually inspected, with radiographic, ultrasonic and PMI testing available on request for critical service. Material Test Certificates per EN 10204 3.1 are provided as standard; 3.2 with third-party witness (TÜV, SGS, Bureau Veritas) is available on request.
Fire-protection mains and hydrant networks, oil & gas gathering and process lines, water and wastewater headers, HVAC chilled-water piping, and general industrial pipework where a durable, code-compliant directional change is required.
