Pipe Repair Clamp Common Failure Causes And Preventive Measures

Although pipe repair clamp is reliable for local pipeline repair,sealing failure may occur in actual operation.The common causes include unclean pipe surface before installation,uneven bolt tightening,aging of rubber gasket,and excessive pipe ovality exceeding the product applicable range.

To prevent clamp failure,operators should inspect the pipe surface and defect size before selection and installation.Control bolt torque according to product specification.For long term service pipelines,regularly inspect the clamp assembly and gasket aging condition.

In corrosive medium environment,select high grade corrosion resistant shell and gasket materials.Reasonable product selection and regular inspection can effectively reduce the risk of secondary leakage and improve the long term stability of pipeline repair.
