ASTM A403 WP316L Austenitic Stainless Steel 90° Elbow

WP316L Austenitic Stainless Steel 90° Elbows are manufactured from high-quality 316L stainless steel and comply with ASME B16.9 dimensional standards. They offer excellent corrosion resistance, high-temperature performance and superior weldability. Designed for changing pipeline flow direction, these elbows provide reliable and stable connections, widely used in pressure piping, refinery, natural gas, chemical plants and industrial fluid transmission systems.

Key Features

• Enhanced molybdenum content provides improved resistance to chloride corrosion in harsh industrial environments.
• Precise dimensions ensure reliable connection with piping systems.
• Suitable for high-temperature applications in refining, chemical and energy industries.
• Low carbon content reduces the risk of intergranular corrosion after welding.
• Provides stable performance for long-term pressure piping operation.
• Widely used in petrochemical, natural gas, pharmaceutical, food processing and industrial piping systems.

Typical Applications

• Used in refinery units, hydrogenation equipment and corrosive media transportation pipelines.
• Applied in natural gas transmission, energy facilities and high-pressure fluid piping systems.
• Utilized in seawater piping and marine equipment due to excellent seawater corrosion resistance.
• Used for clean fluid transfer and high-hygiene piping systems.
• Applied in wastewater treatment, desalination and industrial water circulation systems.
• Used in boiler auxiliary systems, steam piping and industrial fluid transmission equipment.

Precautions

• Avoid prolonged contact with carbon steel or dissimilar metals to prevent galvanic corrosion.
• Use proper welding procedures to maintain corrosion resistance.
• Check dimensions, surface quality and pipeline compatibility before installation.
• Avoid long-term operation beyond the designed temperature and pressure limits.
• Prevent impact, scratches and contamination during transportation and storage.

Quality Assurance

All DINGSCO WP316L austenitic stainless steel 90° elbows are subject to strict inspections, including PT (ASTM E165), tensile testing (ASTM E8/E8M), OES chemical analysis, hardness testing (ASTM E18), ultrasonic testing (when applicable), and dimensional verification. Full traceability is maintained throughout the production process from raw material to finished elbows. MTRs, heat certificates and NDT reports are available upon request.
