Import Tips

• Submit detailed dimensional certificates; inspectors often check OD (must be 215.9+ mm) and wall caliper measurements

• Avoid classifying as drill pipe if not beveled for rotation—pure casing stays here

• Include collapse/ burst test data per API 5CT to demonstrate oil/gas drilling use
