TECNOMATIC EXTENDS MARKET POSITION IN RUSSIA
Tecnomatic increases its presence in the Russian market by the delivery of four new extrusion lines to an important pipe manufacturer in Oryol Oblast. This project, that follows the positive trend already expressed in recent years in the country, is the result of the strong focus and efforts of the company to develop technical solutions that permits saving of material, energy and space; which are the prime conditions for a cost efficient production.
The pipe producer Orelsibgazapparat JSC has been actively developing its activities in the production and sale of polyethylene pipes and fittings for water supply, sanitation and gas supply systems since 1997. Many years of experience, a competent and professional management system, qualified personnel are the result of an annual increase in the production volume.
“ In a continuous effort to enforce our market position offering high quality and reliable polyethylene pipes that meet all environmental requirements we work on modern high-precision equipment, using quality certificated raw materials, and a strict quality control service for all our products. This undoubtedly gives us competitive advantages. We found in Tecnomatic a trustful partner with a common sharing of values. Both companies are experiencing a fast growing thanks to a steady commitment based on the skill and hardworking of people and to the daily continuous wish to improve in terms of applied technologies. Process efficiency in terms of throughput, waste reduction and optimal resource utilization is the natural result of these efforts” commentedAleksei Dubrovin, Managing Director at Orelsibgazapparat JSC.
To grant the production of quality polyethylene pipes, in a wide range and in the shortest time possible the lines, are characterized by reliable technological solutions – such as the extruders Vega with L/D ratio of 37 and Venus heads with internal pipe cooling (PAC) – will produce HDPE pipes with diameters up to 400 mm.
The VEGA series are the result of years of experience in manufacturing extruders and of a constant effort to develop each part of them. A constantly updated screw design, matched with the water cooled straight feed bush, ensure excellent production values with optimal plasticizing, even at high output rate. The specific output has been further increased and it maintains constant across the whole screw speed range or even at high backpressure values.
The machines are equipped with synchronous AC motors specifically designed to be used in applications at high dynamic performances with variable speeds. The selected motors are mechanical sturdy to withstand high overloads while a highly effective insulation avoids a gradual deterioration caused by operation at high frequencies. Italian gearboxes characterised by single block cast iron frame, for large oil capacity cooled by an independent unit, and high performance bearing unit (up to 500 bars) fit out the transmission system of the VEGA series.
To process the high throughput with low backpressure and stress load to the material VENUS die-heads are the proper tools. Based on a spiral distributor concept with a compact design thanks to their innovative geometries and the internal air cooling (PAC system) ensure an optimal wall thickness distribution, ovality and low sagging.
The lines are synchronized using gravimetric system on each extruder, to guarantee a continuous raw material feed and to record variations in mass throughput, thereby ensuring a perfect control of the weight per meter and wall thickness distribution. The downstream equipment includes Tecnomatic’s vacuum & cooling tanks, haul-offs with caterpillar tracks controlled by an independent vector AC motor and planetary saws with knife cutting and universal clamping device, for a very accurate swarf-less pipe delivery.
