There are three common production methods for high-pressure elbows: pushing, bending, and pressing. Pressing elbows with straight sections using molds features advantages such as accurate dimensions, attractive appearance, simple mold adjustment, and high productivity.

Butt-joint high-pressure elbows with straight sections have the following advantages:

(1) Moving the weld joint away from the arc-starting section reduces the discontinuous stress at this position, enhances the pipeline system's ability to withstand alternating stress, and improves the safety of the pipeline system.

(2) During manufacturing and processing, the ovality of the interfaces at both ends of the elbow can be well controlled, reducing the additional bending stress of the pipeline cross-section and lowering the overall stress level of the elbow.

(3) During installation, the butt joint between the elbow with straight sections and the straight pipe can be easily aligned with little misalignment.

(4) The one-shot forming method with a mandrel for manufacturing butt-welded high-pressure elbows with straight sections delivers high quality and low cost, facilitating popularization and application.

In summary, owing to their superior structural performance, elbows with straight sections are widely applicable to high, medium, and low-pressure pipelines in thermal power plants, as well as pipelines in industries such as chemical engineering, petrochemicals, and petroleum. The application of this product will enhance the safety of pipelines.
