CALIBRATION & CERTIFICATION

certification and pressure-testing of plug valves,IBOP valves,chiksan loops

We calibrate and issue certificates for oil installations' pressure relief valves(PRVs).

The image on the left is our 10ft contanerized and fully computerized DNV offshore certified PRV and gauges calibration unit.

We also calibrate and certify mechanical gauges,electrical gauges,temeperature and pressure gauges. Details for JEF TECH limited's PRV and gauges calibration /repair workshop can be found here.

Digital-gauge for calibration of oil rig's pressure gauges

CALIBRATION AND CERTIFICATION OF GAUGES

We have calibrated gauges against dead weight tester.In the process we also carry out leak test through heat exchanger vessel. We have Hydrotesting pump,and pressure recorder, both useful when testing pressure safety valves.

We have tested 14"X600 ball valve for Addax Petroleum at Calabar.We use state-of-the-art Digital gauges.

ELECTROMAGNETIC Inspection(EMI)

Electromagnetic Inspection (EMI) is the process of inducing electric currents or magnetic fields or both inside a test object and observing the electromagnetic response. If the NDT test is set up properly, a defect inside the test object creates a measurable response.

EMI ON PIPES...NDT
electromagnetic magnetic non-destructive testing on pipes

We also maintain and inspect Offshore drilling Equipments.

...plug valves,IBOP valves,chiksan loops(on the left) etc. The machine on the right is a 40,000psi hydraton pressure testing unit. We have used this for Pacific Drilling(Pacific Scirocco, Pacific Bora) and SeaDrill(West Jupiter) etc.

SEQUENCE OF WHAT WE DO IN CALIBRATION

1.Calibration of gauge against dead weight tester
2.Leak test against heat exchanger vessel.
3.Coupling of valve after testing.
4.Hydro-testing pump,pressure recorder with temeperature element on inspection.

We have worked for various clients calibrating their PRVs.

Other services we provide include design and fabrication of cargo baskets,skips,rig stairways,corrosion control of entire rig thus reducing loss of essential rig infrastructure to corrosion.
