Vertical bench for hydraulic tests SPTE 1-4U

Purpose

SPTE 1-4U bench for hydraulic and pneumatic tests of Xmas tree
assembly , injection equipment and blowout proof equipment with a
fl anged connection type of a wellhead equipment in accordance with
GOST 28919-91:

■ tests for strength and density of external cover material and welds
under pressure of the test medium

■ leak tightness tests of the valve gate

■ tightness tests of the sealing of movable and fi xed joints against the
external medium

■ functional tests

Tested products

Connection type

■ fl anged

■ threaded connection for tubing strings

Advantages

■ the bench is equipped with a fold-out upper traverse for
convenient installation of the tested product

■ it is possible to manufacture the bench in a caisson design, when
the table top of the hydraulic press is on the same fl oor level of
the section

■ the clamping unit is equipped with a control panel for clamp
control of the device

■ all parts that come into contact with water are corrosion-resistant
or anti-corrosion coating

■ the power hydraulics of the clamping device operates from the oil
pumping station which increases the service life of the bench

■ valves test for tightness of the valve gate on both sides does not
require reinstallation of the tested valves, which signifi cantly
reduces the time for preparation to the tests

■ usage of high-pressure hoses with quick-release coupling (QRC)
allows to cut the testing time substantially

■ the test bench may be promptly adjusted to the face-to-face
dimension of the the valve due to the available crossbeam with an
electric actuator (depending on the model)

■ the method of the fastening of the tested valves allows to inspect
the leaks
