ª Properties are only valid for products manufactured in the U.S. Mills.
API grades with enhanced performance (EC, HC, HCE, E) are supplied with API couplings produced from standard API grades, unless a premium connection is specified.

Please contact your Vallourec Sales Representative for a grade that is not listed in the above table.
 

​Dimensions, Lengths, End Finishing, Quantities ​

​Dimensions ​Wall tolerance – per API 5CT (-12-1/2%)
O.D. tolerance – per API 5CT (+1.00% / -0.50%)
Length Casing: API 5CT Range 3 = 34’ – 48’; min avg. length of 36’.

Casing: API 5CT Range 2 = 25’ – 34’; min avg. length of 28’

Tubing: API 5CT Range 2 = 28’ – 32’ (up to 34’ with customer agreement)

Tubing: API 5CT Range 3 = 38’ – 42’ (up to 44’ with customer agreement)
Surface Finish ​Mill Coating. (MSDS available upon request)
​End Finish ​Plain End or API threads: LTC, BTC or STC
​NDE ​Non Destructive Examination (NDE) can be provided by Electro Magnetic Inspection (EMI) diverted flux method or through Ultrasonic (UT) inspection. Walls < .440” receive an EMI inspection and walls > .440” receive a UT inspection.
​Hydrotest ​Vallourec Star performs at the test pressure per API 5CT for 5 seconds. Test pressures are set at 75-85% of specified minimum yield strength (SMYS). Higher hold times and SMYS can be technically reviewed.
Mill Test Reports ​Meets the requirements of API 5L SR15.
​Quantity ​Truck shipments must have 20 – 25 tons per load (maximum 4 sizes per truck). Rail shipments must have 75-80 tons per load (maximum of 6 sizes per railcar).
