Metal Angular Expansion Joint

A Metal Angular Expansion Joint uses a metal bellows to create angular movement and absorb changes in pipeline direction. It is suitable for piping layouts where movement must be controlled rather than allowed to occur freely in several directions.

The product normally combines a bellows with hinges, guiding components, or other structural parts. Stainless steel and alloy materials are available, while the end connection can use flanges or end pipes.

Angular movement capability depends on the bellows structure, overall product length, hinge or guide arrangement, and actual installation method. For larger piping movement, two or more angular expansion joint units can be used in pairs or in a combined arrangement.

The system then converts pipeline displacement into controlled angular changes at the designed positions.

This product is suitable for turning pipelines, spatial piping layouts, and compensation systems that need to restrict movement outside the intended direction.

For thermal piping, the angular units can be positioned according to the direction of thermal expansion, pipeline turns, and fixed-point locations. For a turning position with limited space, the hinge direction can be developed according to the equipment interfaces and pipe centerline.

The Metal Angular Expansion Joint places particular importance on movement direction. The hinge or guide components must be installed in the correct orientation so that the bellows moves in the designed plane.

Purchasers should provide the pipe diameter, pressure, temperature, medium, angular displacement, installation direction, connection method, and system load. The location and direction of the hinges or guides should be clearly shown in the drawing to reduce the risk of incorrect site installation.

Yixing Blog Pipeline Equipment Co., Ltd. can review a pipeline layout drawing and system load conditions before developing the product. Bellows, hinges, guides, end pipes, and flanges can be produced within the same project.

Manufacturing capabilities include hydroforming, sheet metal bending, automatic longitudinal seam welding, argon arc welding, and laser cutting. The factory's 200-ton hydraulic sheet bending machine can process lengths of up to 4,000 mm and can be used for different non-standard metal structural parts.

Before production, the technical and process teams can confirm the angular movement direction, connection reference points, component dimensions, and hinge position.

Inspection focuses on corrugation dimensions, hinge alignment, welding quality, and the overall assembly condition. These checks help keep the finished component consistent with the approved piping design.

This product is suitable for spatial piping, turning pipelines, thermal systems, and compensation structures requiring controlled movement direction.

OEM and ODM services are supported. Products can be manufactured according to technical drawings. The minimum order quantity is one piece, making the product suitable for non-standard engineering, equipment modifications, and replacement projects.

The normal production time for one standard specification is about one month. Customized structures, special materials, or products requiring tooling normally require two to three months.

Production photos or videos can be provided. Every product is inspected before packaging, and customer-arranged third-party inspection is supported. Small packages or wooden cases are available.

A six-month industry warranty is provided. Technical personnel can assist with installation direction and operating requirements by phone, online communication, or on-site support.
