Product Detail

Packaging & Delivery

Product Detail

Our petroleum casing products strictly comply with API 5CT and ISO 11960 international standards, and we provide fully traceable factory test reports. Our products cover a wide range of sizes from 4 1/2“-18 5/8” OD, and can be machined to STC/LTC/BTC threaded end or flat end designs to meet the diverse needs of onshore, offshore, and unconventional oil and gas wells. For corrosive environments (e.g. H₂S/CO₂ gas fields), we provide 3PE/FBE coatings and other anti-corrosion solutions to significantly extend the life of the column.

Raw Material Selection

From steel billet and other raw material, chemical components analysis shall be done, in compliance with Standard Specification.Visual inspection is also taken, to prevent the defects, such as pit, crack, blowhole on surface or subsurface.

Quality Control

IMRI Steel pipes mostly come from PQF mill, the most advanced technology for producing seamless pipe world-wide.
NDT methods shall be applied to examine pipe and fittings, without destroying the serviceability of the sampling, mainly including:
*Eddy current testing
*Magnetic particle testing
*Ultrasonic testing.

Physical Testing

Physical testing is intended to test mechanical properties of steel in compliance with Standard Specification or Clients’ request, mainly including:
*Tensile strength test
*Yield strength test
*Elongation test
*Charpy V-notch impact test
*Hardness test (BHN, HV, RC, HRB)
*Hydrostatic test.

Inspection Before Shipment

The Surface, End, Marking, Packing, Quantity and Weight measurement shall be stricly done before shipment.A copy of inspection certificate shall be issued by our QC department, in the name of Baotou Steel.
