Maruhide Pipe Coaster MA Series

The 400MA through 1500MA cover pipe from 34 mm to 1524 mm diameter, each with a rail length from 1 to 18 m and three or five pipe trolleys to suit. The machine is sized to the pipe range and lengths the shop actually runs rather than to a single capacity figure.

Cut shapes are selected from a library on the operation panel, dimensions entered and the part shown in a 3D view before cutting. T-joints, slant and multiple saddles, elbows, mitres, holes and lobster tails are programmed at the machine without CAD.

A laser sensor reads the real diameter, ovality and position of the pipe before the cut. The program is corrected to the material in the chuck, so profiles fit at assembly on pipe that is not perfectly round or straight.

Bevel angle is calculated automatically around the joint so the weld prep is cut in the same pass as the profile, including AWS and API preparations for offshore work. This reduces manual grinding and weld preparation.

Cutting data is generated from AutoCAD DXF as standard, with Tekla Structures and CSV conversion as options, and parts are nested along the pipe length before cutting. A truss of several hundred pipes is converted in bulk rather than programmed one joint at a time.

The torch is held on a magnetic mount that releases during a collision to help protect the torch and minimise downtime. It is refitted by hand without tools or realignment.

With the square rotator and section cutting software, the same machine profiles square and rectangular hollow section, H-beam, channel, angle and flat plate. Multiple joints, crank joints, saddles and hole cuts are made on hollow section as they are on pipe.
