HEAT EXCHANGERS


Heat Exchangers

Heat exchangers are used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact. Heat exchangers, metal shells and tubes, work by transferring heat from one place to another.

Types of Heat Exchangers. 

  • Shell and tube heat exchangers.
  • Double pipe heat exchangers.
  • Plate heat exchangers.
  • Condensers, evaporators, and boilers.

 









How effective are heat exchangers?

 Heat exchangers are used in many engineering applications, such as refrigeration, heating and air-conditioning systems, power plants, chemical processing systems, food processing systems, automobile radiators, and waste heat recovery units.

  

Heat Exchanger Maintenance

 The heat exchanger maintenance consists in cleaning the bundle of inner tubes and the outer shell


Maintenance procedure is carried out in three phases:


  • Tube bundle extraction
  • Tube bundle transport 
  • Bundle cleaning 
  • Tube insert 
  • Inspection and acceptance 



The bundle puller is used to extract tubes from the shell by following safety procedure


The cleaning process of the tube bundles are performed by hydro Jetting (high pressure jet) or chemical cleaning based on process parameters.

Magnetic Particle Testing (MPT)

Image
 Magnetic Particle Testing    Magnetic Particle Testing (MPT), also known as Magnetic Particle Inspection, i.e. a nondestructive examination (NDE) technique used to detect surface and  subsurface diecounitinuties  in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys. Because it does not necessitate the degree of surface preparation required by other nondestructive test methods, conducting magnetic particle test Is part of ASME SECTION V ARTICLE 7 requires the magnetic particle visible method (color contrast) be evaluated with a minimum light intensity of 100 footcandles on the part surface Advantages of the Magnetic Particle method of Non-Destructive Examination are: It is quick and relatively uncomplicated. It gives immediate indications of defects. It shows surface and near surface defects, and these are the most serious ones as they concentrate stresses. Magnetic Particle Testing (MT), also referred to as Magnetic Particl...

Causes of Weld cracks:

Image
 Causes of Weld cracks: Use of hydrogen when welding ferrous metals. Residual stress caused by the solidification shrinkage. Base metal contamination. High welding speed but low current. No preheat before starting welding. Poor joint design. A high content of sulfur and carbon in the metal.

PARA GLIDING AT HALF-MOON BEACH KHOBAR KSA

Image
  PARA GLIDING AT HALF-MOON BEACH KHOBAR KSA   para gliding is a sporting and competitive adventure game of flying paragliders: lightweight, free-flying, foot-sent off lightweight flyer airplane with no unbending essential design. The pilot sits in a bridle or lies prostrate in a cover like 'speed pack' suspended under a texture wing.   Paragliding consist of :  lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure . The pilot sits in a harness or lies supine in a cocoon-like 'speed bag' suspended below a fabric wing. P ara motor is basically a “parachute with a backpack motor” or a “motorized version of Paragliding. For more info   https://paraglidingindia.com/ Myself decided go for paragliding at Khobar, it is at half-moon beach 15 KM from khobar centre The cost for fling 15-20 minutes is 200 SAR per head (dated 2021), The pilot will give demo and safety precaution before flight, my pilot was very friendly. w...
