Rotary pipe scrapers
RITMO’S RTC 160, RTC 315 and RTC
710 are rotary scrapers for preparing
plastic pipes and fittings before
electrofusion welding.
The pipe scrapers remove the
oxidation layer caused by weather and
ultraviolet rays. If not removed, this
oxidation layer would compromise the
quality of the joint.
Among the main construction features
is a device that makes it possible to
maintain a constant thickness of the
continuous chip, even if the pipe is
misshapen, and to adjust the length of
the surface to scrape according to the
depth of the electrical coupler.
The RTC 710 features an extendable
arm to scrape the exact length of the
electrical coupler, which is an advantage
when having to perform maintenance/
repair jobs on a building site. The main
chuck has four extendable arms that
directly clamp the inside diameter of
the pipe.
The external working range is Ø 355
to 710mm, and the maximum length is
530mm. RTC 160 has a working range
from Ø 50 to 160mm, with maximum
length of 114mm; and RTC 315’s
working range is Ø 75 to 315mm, with
maximum length 137mm. The PS line
consists of two models: PS 180 and PS
400. These easy-to-use rotary scrapers
are also used to prepare plastic pipes
and fittings before electrofusion welding.
The tools have an adjustable chuck
covering the whole working range, and
a blade holder orbital arm.
The PS series ensures a constant
and regular removal of the shaving.
The scraper’s blade holder allows the
scraping of the entire electrical sleeve’s
length, most useful when carrying out
on-site repairs.
The PS 180 has an external working
range from 75 to 200mm, and a
maximum length of 129mm; PS 400’s
working range is 137 to 426mm, with
maximum length 150mm.

Automatic punching machine
THE PA-80 automatic punching
machine from SMS Engineering, Italy,
is suitable for punching steel, stainless
steel and aluminium bars with round,
square or rectangular section. It can
produce round and square holes with
or without deformation, and it is suitable
for producing components for shelving,
radiators, ladders, bed frames and
similar products.
Punching can be done to one
side, two opposite sides, or alternate
opposite sides (pitch is variable). The
main features of the machine are pitch
precision, straightness of the worked
bars and fast change of the tooling. The
operator only has to load the piece on
the machine at the right position and
push the start button.
The machine is composed of a heavy,
electro-welded steel frame; a trolley
equipped with special clamping gripper;
special punching units; controlled
axis to manage all tube movements;
hydraulic power pack; and an electrical
cabinet supplied with control panel and
electrical installation.
The maximum tube size is 80mm, with
a standard length of 3m (with options for
4, 5 or 6m); punching power is 3, 6 or
10 tons.
