PARVEEN Lubricator Risers are used to allow the wireline tool string to be raised above the wellhead valve prior to and after wireline operations and enable the wellhead valve to be opened and closed allowing entry and exit of the tool string from the well bore.
An âOâ ring on the pin section forms the seal when made up into the box. The internal thread on the collar matches the external thread on box and makes up quickly by hand.
PARVEEN Lubricator Risers are available in standard lengths from 4 feet through 12 feet, and 2-1/2â through 6.38â bores. Standard end connections include a union box up and union pin and collar (nut) down. Bleed off valves are available in all models upon request. Working pressure ranges for these risers are from 5,000 PSI through 15,000 PSI.
PARVEEN also supplies Light Weight Risers in low alloy steel and 28 chrome stainless steel. Integral designs are also available for high pressures up to 15,000 PSI.
