ASTM tube welding and custom finishing lines supplied to US manufacturing customer

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.

TUBE cutting machine manufacturer Mair Research has supplied a customer in the US with a 4" ASTM tube welding line together with its customised finishing line for the production of Conduit and Sprinkler tubes alongside more conventional tubing. The company, which has more than 40 years of experience in the design, 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. Particular attention is given to tube handling in order to avoid denting and scratching on the tube surface. 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).
