With more than 2500 installations, the PETROSLEEVE® is field proven.
Each PETROSLEEVE® is manufactured to exact specifications to meet the repair objectives of each pipeline situation. Our Quality Control procedures ensure precise design and installation.
Exacting Installation Parameters
Prior to installing a PETROSLEEVE®, the EIP (Engineering Installation Parameters) software determines the sleeve design and installation parameters. The sleeve/pipe/defect assembly is designed to arrest the growth or deterioration of the defect. After installation, the EIP computer software program calculates the stress level in the steel under the PETROSLEEVE® and determines the stress intensity at the crack tip (in the case of a stress concentrating defect).
When the PETROSLEEVE® Repair System is used for a pipe defect, the installation provides additional integrity to the pipe equivalent to a heavy wall section of pipe. When installation is complete, the compression forces between the sleeve and pipe are established, the excess epoxy is extruded from between the pipe and sleeve, and the remaining epoxy continues to cure.
Significant Severe Pressure Testing
Significant cyclic pressure testing was performed in an attempt to extend fatigue cracking. No evidence of crack extension was identified after 35,600 severe pressure cycles.
