Twin-column riser

A rigid single-pipe gantry is a portal-type steel frame structure specifically designed to support a single pipeline. All its components and connection joints feature rigid designs, forming a stable, integrated unit through welding or high-strength bolting. This structure provides robust load-bearing capacity and omnidirectional rigid restraint, strictly limiting displacement and deformation in any direction. It is suitable for supporting single pipelines characterized by large diameters, heavy loads, or stringent spatial positioning requirements, and is commonly found in industrial fixed pipe supports or structural transition zones where thermal displacement compensation or vibration isolation is not required.

A rigid multi-pipe gantry is an overhead, portal-style steel structure designed to provide centralized and stable support for multiple parallel pipelines. All connection joints are rigid—utilizing welding or high-strength bolting—creating a robust, unified framework. This structure offers exceptional load-bearing capacity and overall stability, strictly limiting spatial displacement of the pipes to ensure precise alignment and safety under complex operating conditions. It is suitable for industrial applications requiring rigorous pipe positioning—such as pipe racks in large-scale plant areas or rows of process piping—where the pipes themselves can withstand thermal stresses and allow for vibration transmission.

A rigid rectangular duct gantry is a robust, portal-style support structure designed to carry rectangular-section ducts. Its main framework—comprising uprights and crossbeams—is assembled using welded or bolted rigid connections, while the connection between the crossbeam and the duct also employs rigid clamping. This structure offers exceptional stability and load-bearing capacity, effectively restraining duct displacement in any direction; it is suitable for applications requiring precise duct positioning where thermal expansion compensation is unnecessary and vibration transmission is permissible, such as rigid ductwork systems for ventilation or dust extraction in industrial facilities.

A dual-column riser support is a common piping support structure consisting of two parallel vertical columns connected by crossbeams or mounting fixtures. Its design offers excellent stability and load-bearing capacity, effectively withstanding vertical loads, horizontal forces, and vibrations. Facilitating the installation, adjustment, and maintenance of piping, this structure is widely used in industrial facilities, municipal projects, and building water supply and drainage systems; it is particularly suitable for supporting critical pipelines—such as large-diameter pipes or those requiring long-distance overhead routing.
