A double pipe heat exchanger is a sort of heat exchanger which includes concentric pipes parted through a mechanical closure. The name of this heat exchanger indicates that it makes use of pipes to exchange heat among fluids. One pipe has hot fluid whilst the opposite pipe has cold fluid. These two fluids do not mix with each other as they are separated by pipes. This heat exchanger is likewise known as a jacketed u-tube, jacketed tube, hairpin, and pipe-in-pipe heat exchanger. The double pipe heat exchanger has a small pipe this is surrounded by some other huge pipes. One fluid glide withinside the small pipe, and the opposite fluid acts through the annulus among the 2 pipes. The internal wall of the small pipe is the heat switch surface. The complete warmness switch system takes vicinity withinside the huge tube. In this way, the internal pipe works as a conductive barrier. The outside facet consists of fluid gliding thru the tube facet or inside. This heat exchanger might also additionally have one pipe or a package deal of pipes (however decrease than 30 pipes). The huge pipe has decreased by 2 hundred mm in diameter. In a few conditions, the internal pipe has vertical fins to enhance the heat switch coefficient among operating fluids. Double pipe heat exchangers are used for small heat switch areas (e.g., 14 m2). The collection connection to elevate the heat switch place wishes greater area and greater accessories, which results in a better strain loss. In addition, it isnâ??t always viable to boom the number of fluid passages on each side. This heat exchanger isnâ??t always exceptionally appropriate for grimy drinks due to the fact the grimy liquid will clog it, and the cleansing of this exchanger could be very hard. The essential benefit of the double pipe warmness exchanger is that it has a smooth operation and easy design.
Copper finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the external or internal surface of the heat exchange tube), so as to achieve the purpose of improving the heat exchange efficiency. The overall finned tube has no contact thermal resistance, good heat transfer performance, high strength, thermal and mechanical vibration, and good thermal expansion performance.

Shell and tube heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Shell and tube heat exchangers are general-purpose equipment in chemical, petroleum, power, food and many other industrial sectors, and play an important role in production. There are many types of heat exchangers, but according to the principle and method of heat exchange between cold and hot fluids, they can be basically divided into three categories: partition type, hybrid type and regenerative type. Among the three types of heat exchangers, the partition wall heat exchanger is the most widely used. According to the different heat exchange tube bundles, the partition heat exchanger is divided into: FPR floating coil heat exchanger, LWR threaded tube heat exchanger, and WMH eddy current heat film heat exchanger. Advantages of shell and tube heat exchangers: 1. High heat transfer coefficient: threaded pipe is a high-efficiency heat transfer element combining internal and external threads made of red copper or stainless steel with high thermal conductivity. The threaded pipe heat exchanger made of it has little fluid resistance. , then a strong turbulent flow is formed, which greatly improves the heat release coefficient inside and outside the tube. After testing, the total heat transfer coefficient of steam-water heat exchange is 3000~6000W/m2, and the total heat transfer coefficient of water-water heat exchange is 2500~5500W/m2. 2. Compact structure: This product has a large heat transfer area per unit volume. The total heat transfer coefficient is high, so the floor space is greatly reduced, saving materials and space. 3. Not easy to scale: Due to the special concave-convex structure of the threaded pipe, multi-flow layers and rotary scouring are generated inside and outside the pipe. In addition to the thermal expansion and contraction of the pipe, impurities will not remain inside and outside the pipe wall, so it is not easy to scale. , the long-term operation effect is good. 4. Not easy to leak: The sealing circumference of this product is short, the thick thread of the threaded pipe is similar to an expansion joint, and it has its own compensation ability. The thermal stress of the heat exchanger is small, and it is not easy to leak. 5. Easy installation: This series of heat exchangers has two types: horizontal and vertical, which are easy to install in different positions. 6. Compulsory supervisory inspection, reliable quality: manufactured, inspected and accepted in strict accordance with GB150-1998 "Steel Pressure Vessel", GB151-1999 "Shell and Tube Heat Exchanger" and related standards, and accepted "Pressure Vessel Safety Technology Supervision Regulations" supervision.

Industrial equipment Brazed plate heat exchanger is a new type of high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape stacked and brazed. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Compared with the conventional shell and tube heat exchanger, its heat transfer coefficient is much higher under the same flow resistance and pump power consumption, and it has a tendency to replace the shell and tube heat exchanger within the applicable range. Applications: Refrigeration: used as condenser and evaporator b. HVAC: intermediate heat exchangers used in conjunction with boilers, intermediate heat exchangers in high-rise buildings, etc. c. Chemical industry: soda ash industry, ammonia synthesis, alcohol fermentation, resin synthesis cooling, etc. d. Metallurgical industry: heating or cooling of aluminate mother liquor, cooling of steelmaking process, etc. e. Machinery industry: cooling of various quenching fluids, cooling of reducer lubricating oil, etc. Design Parameters Flow range: 1-2000 m3/h Working pressure: vacuum-8.2MPa Operating temperature: -195-538C Interface size: 1"-DN300 welding, flange, thread and other connection forms Corrosion resistance: Welding seal without rubber gasket, choice of various metal and alloy materials, super corrosion resistance, longer service life. Application field: Crude oil, natural gas purification and chemical products; chemical industry; pharmaceutical and specific chemicals; injection control systems; HVAC, district heating, thermal power plants; food processing; cooling tower heat recovery Process requirements Pickling temperature: Raising the pickling temperature is conducive to improving the descaling effect. If the temperature is too high, it will aggravate the corrosion of the pickling solution to the heat exchanger plates. Through repeated tests, it is found that the pickling temperature should be controlled at 60. 2) Concentration of pickling solution: According to repeated tests, the pickling solution should be prepared according to the concentration of formic acid 81.0%, water 17.0%, buffer 1.2%, and surfactant 0.8%, and the cleaning effect is excellent. 3) Pickling method and time: The pickling method should be carried out by a combination of static soaking and dynamic circulation. The pickling time is static soaking for 2h first, and then dynamic circulation for 3~4h. During the pickling process, samples should be taken frequently to test the pickling concentration. When the difference between the two adjacent test concentrations is less than 0.2%, the pickling reaction can be considered to be over. 4) Passivation treatment: After pickling, most of the scale and metal oxides on the surface of the plate heat exchanger will be dissolved and fallen off, exposing new metal, which is very easy to corrode. The sheet is passivated.
The Extruded Fin Tube also known as� Bimetallic Fin Tube� is one of the most preferred finning processes for various applications. Manufacturing process: Fin is produced by the rolling method (three-roll oblique rolling). Its working principle is: The smooth tube is lined with a mandrel, the tube material is driven by the roller blade to make a spiral linear movement, and is rolled by the roller. The hole pattern composed of the groove and the core rod is gradually processed with fins on its outer surface. In order to facilitate the formation of fins, the rolling parts adopt three stages of biting, rolling, and shaping during the deformation process, so that the processed fins are complete, smooth, and regular. The finned tube produced by this method is based on the base tube and the outer fin is an organic whole, so there is no problem of contact thermal resistance loss and electrical corrosion. It has good heat transfer efficiency and strong resistance to deformation. Extruded finned tubes consist of a light pipe and fins â??attachedâ?? to it. The structural parameters are mainly the inner diameter and outer diameter of the finned tube, the wall thickness of the finned tube, the fin pitch, the fin thickness and the fin height.

A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing, or they may be in direct contact. Classification of heat exchangers: 1. Classification according to construction: Tubular heat exchangers. Plate heat exchangers. Extended surface heat exchangers. Regenerative heat exchangers. Pipe in pipe heat exchangers: Hairpin heat exchangers (often also referred to as â??double pipesâ??) are characterized by a construction form which imparts a U shaped appearance to the heat exchanger. In its classical sense, the term double pipe refers to a heat exchanger consisting of a pipe within a pipe, usually of a straight-leg construction with no bends. However, due to the need for removable bundle construction and the ability to handle differential thermal expansion while avoiding the use of expansion joints (often the weak point of the exchanger), the current U-shaped configuration has become the standard in the industry.
