Materials Used: 20#, Q235A, 15CrMo, 1Cr5Mo, 112Cr1MoV, 304, 316L, 321, etc. Relevant provisions on materials specified in GB/T 12459-2005.
Production Methods: Mandrel Pushing, Press Forming
For the specific manufacturing technical scheme, please refer to the Pipe Fitting Manufacturing Technical Scheme of Hebei Renlong Pipe Fittings Co., Ltd.

There are three common production methods for high-pressure elbows: pushing, bending and pressing. Die pressing for elbows with straight sections features accurate dimensions, attractive appearance, simple die adjustment and high production efficiency.

High-pressure butt-welding elbows with straight sections have the following advantages:
(1) Moving the welding joint away from the arc starting section reduces discontinuous stress at this position, enhances the capacity of the piping system to bear alternating stress, and improves the safety of the piping system.
(2) During manufacturing and processing, the ovality of the joints at both ends of the elbow can be well controlled, the additional bending stress of the pipe section is reduced, and the overall stress level of the elbow is lowered.
(3) During installation, it is easy to align the welding joints between straight-section butt-welding elbows and straight pipes with few misalignments.
(4) The one-piece forming method with core die for manufacturing butt-welding high-pressure elbows with straight sections delivers high quality at a reasonable price, facilitating popularization and application.

In conclusion, due to its structural advantages, elbows with straight sections are widely applicable to high, medium and low-pressure pipelines in thermal power plants, as well as pipelines in chemical, petrochemical, petroleum and other industries. The application of this product will enhance pipeline safety.
