Control system assists in nor-
malizing pipe weld seams to
API standards

The latest pipe alloys, manufacturing methods, and thicker walls make normalizing weld seams on oil and gas pipe more challenging than before.

EFD Induction has developed an improved control system for weld seam normalizing. The system provides three functions crucial for successful, safe, and cost-effective seam normalizing, according to the company. The functions are accurate power control, automatic coil positioning, and various safety, quality, and communication features.

Programmable loader handles
round, shaped tubes

The Hautau SC30 dual-blade shear cutoff machine is available with a new servo-dial loading system for improved handling, feeding, and cutting tube up to 3 in. OD and 0.120-in. wall thickness. It handles rounds, squares, rectangles, and other shapes.

The programmable tube feeder allows cutting up to three lengths from each tube. It makes up to 1,800 cuts per hour with repeatability of 0.005 in. per 30 in. feed.

The fully integrated, programmable dial loading system has a series of tube nests to orient up to 24 tube shapes correctly with the cutoff die. Setup time is less than five minutes.
