Technical Advantages of Pulled Bends

Pulled bends are widely used in oil & gas, petrochemical, power generation, and offshore industries due to their ability to maintain flow efficiency while changing pipeline direction.

Compared with conventional elbows, pulled bends provide:

• Better Flow Performance – reduced turbulence and lower pressure loss.
• Enhanced Mechanical Strength – suitable for high-pressure pipelines.
• Wide Dimensional Range – supporting both small- and large-diameter pipelines.
• Versatility – available in different radii (2D, 3D, 5D) to suit project requirements.

By supplying bends with wall thicknesses up to SCH 120, Haihao ensures excellent durability and reliability even under the most demanding working conditions.
