The facility will manufacture, coat, and internally line 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 :
Pipe Formation Unit
Coil opening operation
-
Coil flattening 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." Pipe Welding Lines (3 Numbers) Entry into pipe welding line no. 1, 2, and 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.
-
End beveling station
-
Hydro-testing station for testing of each pipe
-
U.T. / Ultrasonic testing station for NDT weld flaw detection.
-
End X-ray / continuous radiography
5. 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 ready for dispatch
