Split Sleeve Repair Clamps For Pipeline Leaks

Pipe Remains In Service During Repair

Coupling or Girder type available on shore offshore.

Bolt fasten split sleeves

Westatlantic Split Repair Sleeves for oil, water, gas, steam and chemical fluids pipelines. Split sleeves are widely used for making repairs to a variety of high or low pressure pipelines and high or low temperature pipelines. Large or small pipe diameters, operating pressures to 3700 psi.

The clamp halves are joined by bolts to form a high integrity pressure vessel around the damaged or leaking pipe. Sealing is provided by elastomer seals compatible with the pipeline fluid and operating temperature.

The clamps are fully compensatory pressure vessels, hydrostatically tested to 1.3 times the rated working pressure (as per ASME Section VIII Div.1 clause UG-99) All Clamps are equipped with a 1” NPT vent port.

ANSI pressure classes 300, 400, 600, 900, 1200 and 1500 are available.

Seals of NBR or VITON elastomer seal compatible with the line fluid and ambient temperature, will be installed into the split sleeves.

NBR temperature range is from - 20 C to + 80 ̊ C̊ ; HNBR temperature range is from - 20 C to + 150 ̊ C̊.  VITON temperature range is from - 20 C to + 200 ̊ C̊

Gaskets are replaceable without any special tools.
