Carbon steel 90 degree elbow fittings are essential connectors used to change fluid flow direction in industrial piping systems. Manufactured through hot pushing or induction bending, these components maintain uniform wall thickness and structural stability to withstand high pressure without leaking. We utilize varying grades of carbon steel, such as Q235B and L245, to ensure compatibility with both seamless and welded pipes.
Application Areas
These components are widely utilized in the oil and gas sector, where a reliable carbon steel 90 degree elbow is critical for transporting fluids and natural gas. They are also standard in the chemical industry for handling corrosive liquids when paired with internal epoxy or cement mortar linings. Additionally, municipal engineering projects rely on these elbows for large-scale water supply networks, sewage drainage, and district heating systems, ensuring consistent performance across diverse infrastructure requirements.
Certificates and Standards
We ensure that every carbon steel 90 degree elbow complies with major international standards, holding certifications such as API Spec 5L and ISO9001 for quality management. Our operations also meet ISO14001 environmental standards and EU PED safety certifications for pressure vessels. Furthermore, our anti-corrosion processes adhere to specific industry norms like SY/T0413-2002 and DIN30671, validating that our fittings are safe for use in critical global energy and construction projects.
Our Factory
Located in the Yanshan County Development Zone, our facility operates specialized production lines with an annual output of 300,000 tons. When producing a carbon steel 90 degree elbow, we can fully customize the diameter, wall thickness (6mm-40mm), and bend radius to match your specific engineering blueprints. Our integrated manufacturing process supports rapid scalability for large wholesale orders, and we ensure transparency by providing production progress updates and conducting strict quality control measures, including ultrasonic and hydrostatic testing, before shipment.
Frequently Asked Questions (FAQ)
Q: What anti-corrosion coatings are available for these elbows?
A: We offer a range of external and internal coatings to suit your environment, including Single and Double-layer Fusion Bonded Epoxy (FBE), 3PE (Polyethylene), 3PP (Polypropylene), and Epoxy Coal Tar.
Q: Can you manufacture elbows with non-standard wall thicknesses?
A: Yes. We support full customization. We can adjust the wall thickness and diameter to meet specific non-standard requirements or heavy-duty applications found in your project drawings.
Q: How do you verify product quality before delivery?
A: We implement strict acceptance methods agreed upon in the contract. This typically includes ultrasonic testing to detect flaws and hydrostatic testing to verify pressure resistance, with reports provided upon completion.
