How plate heat exchanger outperform Shell & Tube Units

-
Murphy Plate heat exchangers transfer heat more efficiently than shell & tube units in most applications, due in large measure to the turbulent flow created by the corrugated patterns of their plates. They can pack greater than 22,000 ft2 (2,044 m2 ) of super-efficient heat transfer surface in a single unit with flow rates up to 25,400 gpm (5,768 m3 /hr). They use only 10-50% of the space required by shell & tube units and are much lighter in weight. And, they cost less.

Murphy Plate & Frame
• “U” values several times greater than shell & tube
• Can be designed for less than 2°F (1°C) temperature approach
• Opens for access within its own footprint
• Easy disassembly—simply loosen bolts and roll movable frame back to the support column to remove plates
• Low fouling due to corrugations and inherent turbulence
• Intermix between fluids virtually impossible due to gasket design
• Practically no heat loss—no insulation required



Shell & Tube • Low efficiency
• Typically designed for greater than a 5°F to 10°F temperature approach • Requires twice its length to pull tube bundle
• Complex disassembly—tube bundle must be pulled
• Three to 10 times greater fouling due to circular cross-section and channeling
• Fluids can intermix, both at welds and at tube sheet
• Great amount of heat loss—insulation required

Everything you should know about U bend tube

  Murphy can make  U bend tube  in our factory according to customer requirements. The elbow is heat treated according to the customer’s requirements, and then hydrostatic pressure test and dye penetration test are performed as needed. U-shaped elbows are widely used in  heat exchanger  systems. Heat exchanger equipment based on stainless steel U bend tube plays an important role in the nuclear industry and petrochemical machinery manufacturing. U bend tube heat exchangers are specially designed for high temperature applications, especially steam condensing or hot oil systems. When the differential expansion makes the fixed tube-sheet heat exchanger unsuitable, and in some cases the floating head type (HPF) cannot be selected, the U bend tube heat exchanger will be selected. The surface of the finished U-shaped elbow should be free from scale and scratches after bending. Dimensional tolerance U-bend pipes are in accordance with relevant regulations of TEMA R.C.B. and ASTM A566 and ASTM

Finned tube as a heat exchange element exhibits excellent performance indicators

Finned tube is a kind of heat exchange element, which is often used in high temperature and flue gas space. In daily life, such as boilers, finned tubes need to be used for heat exchange execution. In such a harsh environment During daily operations, the finned tube itself is required to have corrosion resistance and stability. The finned tube is a typical heat exchange element, in order to improve the heat exchange efficiency, usually by adding fins on the surface of the heat exchange tube to increase the outer surface area of ​​the heat exchange tube, so as to improve the heat exchange For the purpose of efficiency, such a heat exchange tube. Finned tubes work under high-temperature flue gas conditions for a long time. For example, finned tubes for boiler heat exchangers are used in harsh environments, high temperature and high pressure and in corrosive atmosphere, which requires finned tubes to have high performance indicators. For example, excellent corrosion resistance. Many tim

1. Metal material heat exchanger Common materials are carbon steel, alloy steel, copper and copper alloy, aluminum and aluminum alloy, titanium and titanium alloy. Because the thermal conductivity of metal material is large, the heat transfer efficiency of this kind of heat exchanger is high. 2. Non-metallic material heat exchanger Commonly used materials are graphite, glass, plastic, ceramics, etc. Because of the small thermal conductivity of nonmetallic materials, the heat transfer efficiency of this type of heat exchanger is low. Often used in corrosive systems. hashtag www.murphyfinnedtubes.com 1. Tube heat exchanger A heat exchanger that conducts heat through a tube wall. It can be divided into shell heat exchanger, coil heat exchanger, tube heat exchanger, fin heat exchanger and so on. 2. Plate heat exchanger A heat exchanger that conducts heat through a plate surface. According to the structural form of heat transfer plate can be divided into plate type, spiral plate
