I NDUS T RY Mair Research supplies high output 4" ASTM tube welding line to US customer

The tube welding line offers a completely automated entry line equipped with a robot for coil strap cutting and strip introduction excluding any presence of the operator, fully automatic mill adjustment, quick change operation by means of motorised trolleys. The finishing line is composed of: tube sample testing chamfering machine, ID scarf flushout, high productivity Hydrotester, grooving machine, coating station, automatic bundling machine and strapping and the line is designed to bundle directly all square and rectangular tubing (mechanical tubing). In terms of conduit or sprinkler tubing, tubes will undergo chamfering, ID flushout, hydrotesting and grooving on both ends. The Hydrotester is a high productivity, rotative type machine and designed to cope with the mill speed and grooving operation is selectable by the operator. The line is completely controlled by a digital system able to trace and follow any single tube. Based on this, the line is able to change order and make the right setup of any single component “on the fly” (washing, chamfering, packaging) without stopping the tube production.

manufacturing and supply of tube and bar finishing lines, commissioned the equipment in 2021 with the main feature of this line being the high output of 20 tubes/min, which the Mair equipment must guarantee to follow with no bottlenecks.
