PIPE REPAIR SOLUTIONS
Based on 30 years of experience, PIPING TECHNOLOGIES have developed a complete range of repair products dedicated to Oil and Gas applications: “couplings” and “ Split Sleeves”.
Split sleeves are widely for making repairs to a variety of high or low pressure and high or low temperature pipeline, including oil, water, gas, steam and chemical process. The clamp halves are joined by bolts to form an high integrity pressure vessel around the damaged or leaking pipe. Sealing is provided by molded elastomer seals of the highest quality selected for compatibility with the pipeline product and operating temperature. The Split Sleeve may also be welded after installation to effect a permanent seal if conditions justify the additional expense. 

Split sleeve cast are designed for faster, easier installation. It may be completely seal-welded with pipe line in operation. 
All PIPING TECHNOLOGIES

Install the upper sleeve and the bolts in the shortest holes
Each half sleeve are marked on one side. Check the marking is on the same side
Lift up the lower sleeve and fit the bolts through the thinner part of the sleeve edge.
Tight up the bolts, following cross pattern at the recommended torque.  
If necessary weld all the edge of the split sleeve
