1. Design and Structure

90-degree Angle: Offers standard right-angle steering and is widely used in various pipe layouts.

Long radius design: Its bending radius is 1.5 times the nominal diameter. Compared with short-radius elbows, long-radius elbows offer less fluid resistance and lower pressure loss, effectively reducing the erosion and wear of the pipe wall by the fluid. They are particularly suitable for conveying slurry, steam and other high-flow-rate media.

Seamless manufacturing: It is made by integral extrusion of seamless steel pipes without any weld seams. This ensures that the elbow has a uniform metal structure and excellent mechanical strength in the key area (i.e., the curved part), fundamentally avoiding the potential leakage risk that may be brought by the weld seam, with stronger pressure-bearing capacity and higher safety.

2. Materials and Properties:

Material: ASTM A234 WPB. This is one of the most widely used grades of carbon steel pipe materials. Its main chemical composition and mechanical properties meet the standard requirements, and it has good strength, toughness and weldability.

Pressure and temperature resistance: It is suitable for a wide range of working environments from low temperatures to medium high temperatures and can withstand high pressure loads.

Durability: It features excellent impact resistance and stress crack resistance, ensuring the long-term safe and stable operation of the pipeline system.

3. Connection and Installation:

Butt welding connection: By welding to the pipe, a permanent, strong and highly sealed joint is formed. This connection method has high strength, almost equivalent to the pipe itself, and is suitable for harsh working conditions such as high pressure, high temperature, flammable, explosive or toxic media.

4. Manufacturing and Quality Assurance:

Production process: Advanced cold push or hot push forming processes are adopted, combined with precise molds and heat treatment processes, to ensure accurate product dimensions, uniform wall thickness and smooth inner walls.

Quality inspection: Each batch of products undergoes strict dimensional inspection, surface quality check and material chemical composition analysis. Non-destructive testing (such as UT, RT, MT, PT) can be provided upon request.

5. Application fields:

This product is widely used in critical industrial fields that require reliable performance and long-lasting durability, including

Petroleum and natural gas: transportation pipelines, refining and chemical plants.

Chemical Engineering and Petrochemical Industry: Inlet and outlet of process pipelines and reactors.

Electric power industry: power station boilers, steam and water supply pipelines.

Shipbuilding industry: Ship pipeline systems.

Water Conservancy and Municipal Engineering: High-Pressure Water Conveyance System.

Structural support: As part of a pipe support or structural component.
