Type B Sleeves Full Encirclement Welded Split Sleeve Repair Clamps for Oil and Gas Lines

Product Name: Type B Sleeves, Full Encirclement Welded Split Sleeve Repair Clamps for Oil and Gas Lines Material: ASTM A36, ASTM A572 Gr.50 Working Pressure: 235-6400 Psi Rubber Material: Buna-N Packing, Viton, Silicone and etc Trademark: GREAT WALL Transport Package: Wooden Box Specification: 4'' to 30'' Origin: China Product Description 1. PLIDCO Type Full Encirclement Welded Split Sleeves are typically used for two applications: pressure containing and non-pressure containing .A. pressure containingThe 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 containingThe 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 TypeFull 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 TypeFull 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).
