مقدمه :
روغن سرد کن ها در اکثر پروسه های مربوط به صنعت پتروشیمی ، پالایش نفت ، پالایش گاز ، سیستم های انتقال در خطوط لوله گاز و خطوط انتقال انواع مایعات نفتی و غیره مورد استفاده قرار میگیرد .
جای مباهات است ، به اطلاع برسانیم ، تمامی روغن سرد کن های به روز در دنیا ، با تکنولوژی های متنوع و پیچیده از دید ما پنهان نبوده وواریانت های معرفی شده در ذیل حاکی از وسعت میدان فعالیتی است که در ذیل به شرح تک تک آنها پرداخته شده است .
تکنولوژی های خاص هر یک از محصولات معرفی شده که امروز جزو تولیدات این شرکت میباشد ، حاصل ۳۵ سال تلاش بیوقفه و فعالیت در عرصه طراحی مهندسی معکوس است که به منصه ظهور رسیده است .
مدیریت پایدار حکم میکند ، همواره خود را با پیشرفت زمان مطابقت دهیم ، برای رسیدن به این هدف دپارتمان طراحی و مهندسی این مجموعه کوشش میکند ، از تکنولوژی های نو غافل نشود ، و همواره up to date بماند .
این خبر برای مشتریان ما نوید بخش خواهد بود ، که ماشین آلات اکثر تولیداتمان را خود ساخته ایم و تعداد کمی آز آنها را از داخل و یا خارج خریده ایم .
دقت در ساخت و کیفیت کنترل شده و کار مطابق با نقشه و رعایت استاندارد را قبل از آنکه استانداردی در ایران اعمال شود آزمودهایم ، و نقشه های دقیق ۳۰ سال پیش ما مبین این مدعاست .
روغن سرد کن هائی که در رابطه با صنعت پتروشیمی ، پالایش نفت و گاز ونیروگاهها امروز در این شرکت تولید میشود عبارتن از :
– رادیاتور های روغن سرد کن نوع ماریستون انگلیس ( این رادیاتور در ۳۵ سال قبل جزد تکنولوژی های برتر اروپا محصوب میشد )
– روغن سرد کن های آلمانی از نوع لوله بیضی شکل ( رادیاتور های لوله بیضی هنوز جزو تولیدات به روز بوده و در صنعت روغن داغ و روغن سرد به خاطر turbulence داخل لوله کاربرد بسیار دارد )
– روغن سرد کن از نوع سیم مسی بافته شده بر روی لوله ( این دستگاه در پروسه های پتروشیمی و پالایش نفت استفاده خاص داشته و هنوز از آمریکا ویا کشور های پیشرفته وارد میشود )
– روغن سرد کن های با فین تخت مخصوص و استفاده از لوله های نازک و braze شده ( این مبدلها نیز در اکثر پروسه های تولید و خنک کردن با طیف وسیع کارد برد دارد )

Fin Tubes- Wire Wound (Pin Fin Tube) Fin Tubes,
stainless steel wire wound tubes,
copper wire wound finned tubes,
galvanized wire wound fin tubes
for Air Heaters, Air Coolers, Oil Coolers
- without Turbulators
- Wire wound root soldered fin tubes with base tube diameters ranging from 3 mm to 100 mm with fin heights between 2 mm to 28 mm are manufactured at Eye sun tahvie engineering, iran , Stainless Steels, Carbon Steels, Copper and Copper Alloy tubes are finned with Stainless Steel, Mild Steel and Copper Wires.
- The tubes can be provided with turbulators inside to enhance tube side heat transfer coefficient for use in air cooled oil coolers.
- Our special finning machines fin tubes in any lengths even exceeding 6 meters. The loops of wire are continuously root soldered on the finning machine. Infinite combinations of loops per turn and turns per foot are possible.
- Solders used withstand tube wall temperatures up to300 deg C. Special solders are used for temperatures between 300 C and 450 C. Wire wound tubes are not suitable for tube wall temperatures exceeding 490 C.
Why use a wire wound fin tube?
- Wire wound fin tube consists of a base tube with oval or near rectangular loops formed of wire which are wound helically over the tube with root soldering of foot of every loop to the tube.
- The loop of wire creates greater turbulence thereby increasing the heat transfer coefficient. Root soldering along the entire length eliminates almost all air gaps between the fin and the tube.
- For most applications, wire wound fin tubes make it possible to design a much compact heat exchanger coupled with lower pressure drop compared to conventional fin tube
Wire Wound Fin Tubes with Base Tubes of:
Stainless Steels , Carbon Steels , Copper , Ad. Brass , Cupro-Nickels
Oil Cooler Assembly
We are engaged in manufacturing oil cooler assembly which is known for its effectual functioning among our valued clients. Our range is fabricated from oil cooler tubes with turbulators inserted, M.S fabricated tanks, copper fins and brackets which is used in substitute of imported aluminum oil cooler. These oil cooler assembly are essential for:
- Cooling Hydraulic
- Transmission oil in HEM
- Construction Equipments
Following are its noteworthy features:
- High performance
- Durability
Furthermore, these can be easily modified in compliance with client requirement and can be delivered on time.
Wire Wound Tubes
We manufacture spring and and zig zig type tubes, known as wire wound tubes which are known for its effectual functioning and is highly appreciated among our valued clients. Fabricated from qualitative copper and mild steel these wire wound tubes are wrapped around the outside base of the tube with both ends brazed to the base tube. These types of tubes are essential for oil coolers and for drill machines like:
- RECP
- IDM
- CPT Compressors
Moreover, these are manufactured in accordance with client necessity and can be delivered within stipulated time frame.
Finned Tubes
Generally, addition of any metal piece to a heat transfer tube is an extended surface. The addition or attachment of these metal pieces serves a purpose greater than just increase in external area. These pieces are commonly referred to
as fins. The fins increase the total heat transfer area, but the process of heat transfer in fin tubes is quite different than simple conduction and convection.
Transverse or Radial Fin Tubes
As the name suggests, transverse or radial tubes are attached perpendicular to the axis of the base tube or pipe. The fins may be applied or attached to the outside of the fin tube or rolled up from the parent metal of the finned tube. The common types of transverse or radial fin tubes are:
Helically Wound Spiral Crimped Fin Tubes
These consist of a strip of metal of suitable width and thickness tension wound on tube. Unless root soldered at base, the percentage void space between the fin and the outside surface of the base tube cannot be ascertained. This leaves some doubt in my mind about the actual performance. The maximum operating wall temperature for this type of root soldered finned tubes is 290 deg C.
Wire Wound Fin Tubes, Pin Fin Tubes
Root soldered wire wound tubes consist of loops of wire helically wound over the base tube. The foot of each loop is root soldered to the outer surface of the tube. The key factor here is use of proper tension wire and good soft soldered bond of the fins to the external surface of the base tube to eliminate all voids between the base of the looped fin and tube. The maximum operating wall temperature for this type of finned tubes is 290 deg C
Shell and tube oil coolers:
|
|
| Stainless steel oil coolers
Stainless Steel Heat Exchangers are particularly useful in bad water environments caused by pollution or from the chemicals used to counter it. They can also be used to overcome the corrosive nature of some synthetic oils and refrigerants. |
|
| Charge oil cooler
this charge air coolers are popular for test bed engines. |
|
| Hydraulic oil cooler
The Hydraulic Oil Coolers are suitable for heat transfer fluids, lubricating, transformer & quenching oils. They are high quality products incorporating the best materials and the latest technical features. The tube stack is fully floating so that thermal stresses are minimized and it can be easily removed should cleaning be necessary. |
