Sealing groove used in spiral plate heat exchanger equipment

-
Spiral plate heat exchanger devices used by the plate on both sides of seal groove, of course, there will be a continuous distribution side, and, in general, actually a side is straight, the other side also is irregular corrugated side. The continuous side edge in the center will provide strong support to the gasket, but the corrugated side edge of the plate and the corrugated side edge of the gasket will also realize just biting each other, which will make the gasket more firmly fixed on the plate, not easy to slide out of the seal groove due to pressure fluctuations and other reasons.
The plate used in the helical plate heat exchanger equipment, Murphy experts use new technology and make non-bonding gasket appears to be very easy to install, and the ridgelike projection on the outside of the gasket just matches the groove on the back of the other plate, so that the whole plate group can get stuck when clamping to avoid dislocation.

 Spiral plate heat exchanger equipment in the use of special adhesive and high temperature curing bonding process. In the same industry, the high temperature curing and bonding process is adopted. The sealing adhesive will choose special products produced by 3M company in the United States according to the water quality characteristics, and then it will use the supporting glue coating equipment to spray the adhesive.
In this way, to a large extent, it can guarantee the bonding stability of the sealing gasket of the spiral plate heat exchanger and the service life of the sealing gasket. After the bonding of the plate and the sealing gasket, under certain preloading conditions, it is necessary to pay attention to the need to be put into a 160℃ high temperature oven to dry for 8 hours at a constant temperature.
At this time of the spiral plate heat exchanger on the plate and the sealing gasket also occurs between high temperature of polymerization, which in turn makes the plate and sealing gasket glue more solid, it is because of this, the assembly after the spiral plate heat exchanger plate of the operating mode of under 160 ℃ after repeatedly disassembling, will its sealing gasket will not appear fall off phenomenon.

  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 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
