The facility manufactures, coats, and internally lines Large Diameter API Grade Pipe with a diameter range of 24" to 60", a wall thickness range of ¼" to 1", lengths up to 80’, and grade up to and including X80. Annual plant capacity will ultimately be 300,000 short tons depending on order mix.

The "two step Helical Seam" pipe mill consisting of the following steps :

Coil opening operation

Welding coil to coil butt ends for continuity
Pipe forming operation
Continuous tack welding of the formed pipe.
Pipe end cutting operation.

This completes the first process of "pipe formation."

Pipe is then discharged to "Final Welding."
Entry into pipe welding line no. 1, 2, or 3.

Functioning of the welding lines attached to the "pipe formation" station undertakes the following operation :

Continuous internal welding
Continuous external welding

The duly welded pipe is discharged from the welding line for processing of the pipe ends.

Hydro-testing station for testing of each pipe
U.T. / Ultrasonic testing station for NDT weld flaw detection
End X-ray / continuous radiography
End beveling station
Finishing station and final inspection station

The finished pipe is then transported to storage or to a separate building for external/internal coating.

Fusion Bonded Epoxy External coating line, followed by
Internal coating line, Liquid Epoxy as per customer’s requirement.

Finished pipe is now ready for shipment.
