Rotating Cooling Table

ESG has designed and refined the cooling disc table to provide an excellent service factor while reliably maintaining good quality production.

Why is rotation needed?

When the pipe exits the temper furnace the cooling is relatively fast. Non uniform cooling on the pipe will cause stresses as those cooler sections and they start to contract. In the best case it instills stresses in the pipe body that it wants to relieve. In the worst case, it can cause a tube or pipe to bend. This is why in many operations a gag straightener is present to take care of these immediate problems. A better solution is the ESG rotating disc table.

The fast rotation of the ESG disc table allows natural draft cooling to take place, but it is uniform throughout the circumference of the pipe. The disc contact point, unlike a rail, is narrow and will heat up and not cause point of contact cooling like a drag chain table. The table also has an added benefit, if a tube already has a bow, the table will allow the piece to straighten as it goes through the upper end of the cooling curve. The results we have seen is consistently straight pipe that does not need to go through a straightener.
