McElroy Introduces Rolling 28 Hand-Pump Fusion Machine

Press release date: October 7, 2010

Rolling fusion machine incorporates double-action hand-pump

TULSA, Okla. - McElroy's new Rolling 28 Hand-Pump (HP) fusion machine combines the versatility and convenience of a rolled chassis with a hand-pump fusion carriage for fusing 2-inch IPS through 8-inch DIPS high-density polyethylene (HDPE) pipe sizes (63mm through 225mm).

The Rolling 28 HP features a double-action hand pump that works in unison with high-velocity cylinders to create fast carriage speeds for quick opens and closes during fusion processes. The new machine comes standard with McElroy's powerful electric, pivoting facer and microprocessor-controlled heater.

The Rolling 28 HP offers comfort and convenience advantages by bringing the fusion process up to a more natural work height for the operator, while offering dual pipe lifts for increased productivity.

"The Rolling 28 HP is a reincarnated machine," said Chip McElroy, president of McElroy. "An older variant of this very machine helped put McElroy on the map many years ago. The industry appeal of the Rolling 28 HP went away, but it is back now in force, and we are happy to manufacture a new version of an old classic to help contractors."

With a 1,500 psi fusion pressure capability, the Rolling 28 HP is a rugged and compact machine. The fusion carriage can be removed in either a three- or four-jaw configuration to go in-ditch or for other situations where space is limited. The machine is DataLogger® compatible, uses McElroy's patented Centerline Guidance System for equal distribution of force around the joint and includes thrust-bearing-equipped clamp knobs to minimize the force required to clamp and round the pipe.

About Pipe Fusion:
Pipe fusion is a widely accepted process that joins two pieces of thermoplastic pipe together with heat and pressure. Commonly associated with high-density polyethylene pipe (HDPE), the butt fusion process starts by "facing" or shaving the pipe ends simultaneously so that they can be joined together with heat to create a continuous, sealed pipeline. The welding of the pipes is accomplished by using a hot plate in contact with the pipe ends, which heats the plastic to a molten state. Then, after its removal, the ends are pressed together under a controlled force to form a weld that is as strong as or stronger than the pipe itself. Third-party industry research indi-cates that HDPE pipe and joints can have a lifespan of more than 100 years.
