Material Test
Chemical Composition Testing
Chemical composition analysis to ascertain the chemical composition of each heat of steel by Spectrometer.
Specimen will be taken and tested both pre-pouring and post-pouring to control the chemical composition within the specification.
The specimens being tested also are kept well for two years ,and are available for re-checking upon request.
Material report with chemical testing results will be provided for each shipment.
Mechanical Property Testing
(1).Metallographic Examination
Metallographic Examinations are done after heat treatment to check the microstructure of materials to ensure the proper Mechanical Property of the Cross Coupling Cable Protector
(2).Hardness Test
Hardness tests are checked in standard of Brinell and Rockwell, and compared with the standard of the material of the Cross Coupling Cable Protector.
(3).Mechanical Property Test
Mechanical Property Test are done each heat treatment to get the results of Tensile strength, Yield strength, Elongation ,etc, and compared with the standard of the material.
Non Destructive Testing
Non Destructive Testing, such as Magnetic Particle Examination, X-Ray Test, Ultrasonic examination can be performed upon request to body and straps of Cross Coupling Cable Protectors(CCCP) to check the internal defects, and insure the parts are structured perfect to have the enough strong strength for completion jobs.
Dimensional Inspection
Dimensional inspection will be done for both the body and the collars for our Cross Coupling Cable Protector (CCCP) when steel casting parts or machining parts are finished in both process audit and final inspection.
Process audit will be implemented during the whole production process according to the production plan and process card. Inspection results are recorded and analysed.
Special gauges are created ,and use for checking the slot and radius of the body and straps ,and insure the downhole cable protector is 100% functional fitted, and the results after assembly is good enough.

Functional Inspection
All the Cross coupling Cable Protectors have to be tested to verify the function and performance.
(1).Fitting Test of protector to coupling
Every Cross Coupling Cable Protectors / Downhole cable Clamps are checked on the coupling accordingly to ensure correctly assembly and right for tubing. Special testing fixture and checking gauges are made with full size of different sizes of tubing and coupling.
(2).Torque test
The Cross Coupling Cable Protectors/ Control line Protectors stand Torque by the bolts locking of 30 ft./lbs. Torque test are done each lot to ensure the locking strength strong enough.
(3).Cable slippage test
The Cross Coupling Cable protectors/ Downhole cable Clamps also go through the Cable slippage test to over 500 N to ensure the cross coupling cable protector holding the cable correctly and strong enough and no damage to the cable during the downhole working.
(4).Drift test
Assembled cable protectors/Control Line Protectors are pass through the drift test to ensure that the protectors will pass through the specified Well Casing while installing them during the well completion.
(5).Axial load and side load test
The Cross Coupling Cable Protectors/Control Line Protectors are designed to stand 20 tons of Axial load and Side load. Special fixtures and test gauges are equipped to do the testing accordingly to ensure the strong enough structure designing and good performance during installation.
