Three Bolt Pipe Clamp
The Three Bolt Pipe Clamp utilizes a triangular stable structure, and its three-point fastening design reduces bolt stress by 30% compared to ordinary two-bolt pipe clamps under the same working conditions. Verified by SAE J2380 standard vibration testing, its anti-loosening capability is improved by more than 50%, making it particularly suitable for heavy-duty pipelines from DN80 to DN500. This product is widely used in high-vibration pipeline sections in the petrochemical and power industries, capable of supporting pipeline loads up to 20 tons, and provides a 1000 Nm installation torque guideline to ensure a torque retention rate of over 85% under long-term operation.

INSTALLATION AND ENGINEERING KEY POINTS
Torque Control: The three bolts must be tightened in a cross-pattern sequence using a calibrated torque wrench to achieve the designed pre-tension force and ensure even stress distribution.
Bracket Design: The strong rigidity requirement demands that the supporting steel structure has sufficient local rigidity and overall stability. The mounting base plate should avoid excessive overhang.
Maintenance and Inspection: During regular maintenance, it is recommended to recheck the bolt torque. For critical pipelines, a hydraulic torque wrench can be used for precise maintenance.

FAQ
Q: Are there strict requirements for the tightening sequence of the three bolts during the installation of the Three Bolt Pipe Clamp?
A: Yes, there are strict requirements. The tightening sequence must follow a "diagonal cross, step-by-step incremental" method (e.g., pre-tighten all bolts to 30% torque, then tighten to 100% of the design torque in two steps following a diagonal sequence) to ensure the clamp plates are evenly fitted and prevent uneven pressure on the pipe. We provide installation guidelines with diagrams and torque values.
Q: Is there CE certification?
A: We hold CE certification (EN 1090-1) and ISO 3834-2 welding system certificates, and provide EN 10204 3.1 material reports, meeting EU access requirements.
Q: Do you support OEM/ODM customization?
A: Yes. Laser marking and packaging customization can be done according to brand specifications, and a flexible solution with neutral packaging plus separate brand accessory packages is also available.
