Technology Update
CARELL Corporation has introduced the
310HV4 angle roll with 6" pipe and 6"
angle bending capacity. The fully hydraulic
universal roll bending machine features
three driven rolls and double initial pinch,
with independent hydraulic adjustment
of both lower bending rolls and hydraulic
powered rotation of all three rolls.
Lateral guides are hydraulically powered
in all three axes (six directional movements).
Carell universal angle rolls are suitable for
rolling standard or special profiles, tube/
pipe and beams in a variety of material
types and alloys. Tooling for angle iron
leg-in and leg-out is standard. The 310HV4
pictured is equipped with an articulated
overhead pendant control arm, allowing
maximum operator mobility and safety.
The 310HV4 has two LED digital displays
to monitor bending roll positions and six

OSCAR Production Group is a manufacturer
of heat and corrosion resistant tube and pipe
in titanium, nickel alloys and special stainless
steels. The company was established from
the production and technical facilities of the
Tube Drawing Workshop No 4 (TDW-4)
of the original Nikopol Yuzhnotrubny Plant
(NYTB) Ukraine, which was built in 1975.
The company’s products are intended
for industries that have severe process
applications, such as the nuclear power
industry, aerospace industry, chemical
and petro-chemical industries, oil and gas
exploration and production, ship building
and defence industry, in addition to other
industries that require high specification
tubes and pipes for difficult applications.
Oscar Production Group uses cold
forming technology (cold rolling and cold
drawing) to produce high quality tube
and pipe in titanium, nickel alloys, special
stainless steels and zirconium based alloys.
The company can manufacture materials
with a wide range of specifications,
depending on customer requirements.
Product sizes range from 0.3 to 133mm
diameter, 0.08 to 15mm wall thickness in
seamless tubes; ¼" nominal bore to 4"
nominal bore in sch 5, 10, 40 and 80 pipe;
16 to 76mm diameter multilayer (2 to 12
Heat and corrosion resistant tube
LED digital displays to monitor all lateral
material guide positions. Each machine is
built with a rugged, rigid and reinforced,
one-piece solid steel weldment frame that
is stress relieved and then CNC machined.
All shafts are made with high strength alloy
then heat treated and ground for durability
and precision fit.
The 310HV drive train is 100% hydraulic,
using three independent radial piston
hydraulic motors and planetary speed
reducers direct coupled to each main roll
shaft for 100% torque transmission to the
work piece. Hydraulic drive trains require
near zero maintenance. The hydraulic
drive train features infinitely variable speed
rotation, 0-23fpm, using a digitally driven
hydraulic proportioning valve and a control
panel mounted potentiometer. Hydraulic
pumps are driven by a 30hp TEFC IEC high
efficiency electric motor.
The standard universal bending roll
tooling set uses telescoping modular
components and includes nine major roll
components machined from NiCrMo alloy
steel, which is induction hardened for
extended life. Nominal roll diameters are
18.75" OD.
The 310HV4 weighs 20,500lb and is set
up for operation in the horizontal working
plane. Machines of size, 6ft x 8ft x 7ft can
be placed in a machine pit to afford a lower
working height.

layers) tubes, with thickness of individual
layers of 0.16 to 0.25mm; and extremely
thin-walled and ribbed tubes of titanium
alloys in a standard size range. Extra
long tubes can be produced depending on
customer requirements.
The Oscar Production facility is equipped
with 60 units of rolling equipment: 10 cold
pilger mills, 41 tube rolling mills of roller
design and 9 drawing mills.
