Product Description

Full Encirclement Welded Split Sleeves
 

1. PLIDCO Type Full Encirclement Welded Split Sleeves are typically used for two applications:
   pressure containing and non-pressure containing .

 A.  pressure containing 

The application is pressure containing when the split sleeves is installed over a known leak .
For a pressure containing application, the wall thickness of split sleeve and all welds must be able to contain the full operating pressure of pipeline .
The longitudinal weld joint formed by the two halves of the split sleeve must be a full thickness butt weld .
The circumferential joint formed by the split sleeves welded to pipeline must be a full thickness fillet weld . 

B. Non-pressure containing 

The application is non-pressure containing if the split sleeves is not installed over a known leak and the intended use is only to reinforce a damaged area of the pipe.  
The longitudinal weld joint formed by the two halves of the split sleeve must be a full thickness butt weld .
The circumferential joint does not have to be welded, but should be sealed with a coating to prevent ground water from penetrating the crevice between the sleeve and the pipe .
If the circumferential joint is welded, the application should be assumed to be pressure containing and all the requirements of a pressure containing application now apply .

2. PLIDO Type Full Encirclement Welded Split Sleeve are usually fabricated in length of 5 or 10 feet.
But you can define the length of split sleeve as per your own demand .
Back-up  strips for the longitudinal butt welds are furnished with all sleeves .

3. PLIDCO Type Full Encirclement Welded Split Sleeve conform to ASME B31.4 and B31.8 as well as US Department of Transportation (US DOT) requirements . Individual company codes and safety pratices should be observed .US DOT requires that population density be considered in the installation area for natural and other gas pipelines ( DOT section 192.5).
