U Bolt

Benefits

• High Structural Pipe and Tubing Containment: Wraps around the outer diameter of pipes and structural tubes to deliver firm, 360-degree restraint against hydraulic surge forces and severe line vibration.

• Versatile Mounting Profiles: Available in round bend, square bend, and semi-round bend configurations to match specific pipe sizes, structural steel beams, and square tubing profiles.

• Thermal Expansion Accommodation: Can be installed with rubber liners, thermoplastics, or calculated gap spaces to allow process piping to expand and contract smoothly without causing localized pipe wall fretting or stress fatigue.
  
  

  Applications

  U-bolts are fundamental pipe support and structural clamping components widely deployed across industrial processing facilities, automotive chassis systems, and offshore marine construction. In oil refineries, petrochemical plants, and chemical processing facilities, hot-dip galvanized and PTFE-coated U-bolts secure major overhead process pipelines, utility lines, and flare stacks to structural steel racks, absorbing intense line pulsation and wind shear. Automotive and heavy vehicle manufacturing lines depend on high-tensile alloy steel square-bend U-bolts to clamp heavy-duty leaf spring assemblies securely to truck and trailer drive axles. Thermal power generation plants integrate stainless steel (316/316L) U-bolts along high-pressure steam and condensate return loops to provide rigid guide support while accommodating continuous operational thermal movement. Additionally, marine engineering infrastructures and offshore drilling platforms employ high-corrosion-resistant Duplex and Super Duplex U-bolts with thermoplastic lining pads to secure seawater intake lines, ballast piping, and subsea risers against severe wave action, crevice corrosion, and galvanic degradation.
