Techshore Explains Pros and Cons Of Oil and Gas Energy

Uncategorized
There is no faultless energy source. Each plus everyone has its own benefits and concessions. This series would explore the pros and cons of oil and gas energy. Natural gas has been in the newscast a lot recently, being hailed as the answer to our energy difficulties on the one hand, and a possible ecological nightmare on the other. Let us try to sort out the realism behind this old friend by a new face. Beforehand we start, it may be useful to make a difference among the natural gas that has factually been collected as a byproduct of oil drilling in addition to the more lately promoted source recognized as shale gas. This has converted newsworthy as the consequence of a huge deposit of shale gas exposed in the…

Techshore Inspection Services-Kochi- Wet Riser system using in Firefighting

Uncategorized
Do you know about Wet Riser system using in Firefighting?   Wet Riser System The Wet riser system providing for residential building should require the following features: The Wet riser generally designed for zonal distribution of water required as per the height of the building. The first riser up to 60 m height should be 100 mm diameter. The second riser up to a 100m height of 150 mm diameter. The third riser up to 150 m height of 150 cm diameter. These risers are connected to separate fire pumps provided for this purpose in the building concerned. A wet riser required to be provided near the enclosure staircase. The pipe system shall make approved and quality by the competent authority. The typical Wet riser system is shown in the…

TECHSHORE INSPECTION SERVICES-KOCHI-KERALA | REBAR LOCATOR

Uncategorized
Techshore Inspection Services Kochi-Kerala| Rebar Notes Principle The Principle of Rebar Locator is that it can be worked either by utilizing Eddy current effect or Magnetic induction effect.In cover meters using eddy current effect, current in the search coil set up eddy currents in the reinforcement which in turn causes the measured impedance of the search coil to change. Instruments using this principle operate at above 1 kHz frequencies. They are thus sensitive to the presence of any conducting material in the vicinity of the search head. In cover meters using magnetic induction effect, a multi coil search head is used with a lower operating frequency of less than 90 Hz compared to the eddy current type device. Here the principle used is similar to that of a transformer. In…

Techshore Inspection Services -Kochi-Kerala | Vapour Compression Notes Introduction Vapor compression refrigeration cycle is the basic working cycle of a refrigeration system. The vapor-compression refrigeration system uses a circulating medium called refrigerant is the medium which absorbs heat from the space to be cooled and subsequently rejects that heat from the room to outside. Figure describes a typical, single-stage vapor-compression refrigeration system. It have primarily four components: compressor, condenser, thermal expansion valve (also called a throttle valve), and evaporator. Circulating refrigerant enters the compressor in the saturated vapor state and is compressed to a higher pressure, higher temperature vapor. The high temperature, high pressure vapor is then in the superheated vapor and it is at a temperature and pressure at which it can be condensed with cooling water or cooling air flowing across the condenser coil…

Techshore : Working Of A Magnetic Particle Test

Uncategorized
Introduction This article explains the principle behind magnetic particle test. when this test is done on a ferromagnetic material we can see that magnetic flux is easily distributed into the material without any interruption as because the material is entirely defect free .the magnetic flux is aligned into the material along north to south direction. When there is a defect inside the test material, and when we apply magnetic field into it, we can see that flux being distributed every where uniformly except the defect area. flux leaks out of the material under test where there is a defect. then the next step is to apply iron powder onto the area being magnetized, then the iron particles will be collected by the magnetic flux, the collected iron powder helps us…

Techshore : Magnetic Flow Meter

Uncategorized
Introduction Magnetic flow meters are widely used to measure the flow rate of conductive liquids in process applications. Recent technological developments have been made them relatively easy to install and often more economical than other designs. A primary advantage of this type of instrument is that magnetic flow meters provide virtually unobstructed flow. Because the flow path is relatively unobstructed, they are well suited to use with high viscosity fluids that contain solids. Important application includes flow measurement of sludge in sewage treatment plant, quarries in mining operations, and liquid metals in various industrial processes. In addition magnetic flow meters do not create pressure drop. Velocity is measured directly and thus variations in density do not affect their accuracy. Further these instruments are free of Reynolds number constraints; they may…

Techshore : Process of well treatment

Uncategorized
ACIDIZING Acidizing is a process of cleaning the formation face to allow fluids to enter the well bore . A limited amount of dissolving of formation particles can occur if the acid can be forced far enough into the formation before the acid is expanded. FRACTURING Fracturing process is done by high pressure pumps so has to develop enough fluid pressure at the bottom of a well which will actually crack (break) the formation .This makes it possible to introduce prop pant materials such as sand , walnut hulls ,or other small particles of materials into the newly created crevices to keep the fractures propped open when the pressure is relieved .This process increases the flow of reservoir fluid into the well bore . HYDRAULIC FRACTURING A fracture is a…

Techshore : Dry chemical powder extinguisher

Uncategorized
Introduction Dry Chemical Powder: - It is used to combat fires in flammable liquids, gases and greases include such fires when involved with energized electrical equipment is a potassium bicarbonate based dry chemical. The chemical powder is free flowing, water repellent and nonabrasive and when used as a fire extinguisher agent will produce no toxic effects. Because of its excellent firefighting effectiveness this product is widely used in other high risk areas. Carbon dioxide or Nitrogen is used as an expelling gas. This system can be effectively installed in restaurants, fuel stations etc. Various chemicals are used in dry powder extinguishers depending on job they are intended. For example; Sodium Bicarbonate – For flammable liquids Potassium Bicarbonate – Used in USA for class ‘B’ fires Ammonium Phosphate – ‘General purpose’…

Techshore : Hysteresis Curve

Uncategorized
Introduction The above figure demonstrates the relationship between flux density-B and magnetization force-H of a ferromagnetic material. initially the material is in its normal state which means its not being magnetized hence B=0 and H=0.we plot the relation between B and H in such a way that X- axis represents the magnetization force(H) and Y-axis represents flux density (B). So here we study what happens to the flux density in the material if the magnetization force is increased and also decreased. so in the beginning we increase magnetization force to a positive value and hence we can see there is a steep increase in the flux density and further when H is increased the increment in flux density becomes gradually slow that it reaches a saturated state which shows there…

Techshore : Variable Area Flow Meters

Uncategorized
Rotameter The name rotameter was chosen in the past because at one time the float was designed with slots to produce a rotational movement for the purpose of centering and stabilizing the float. The float is free to move up or down within the tapered tube. The tube is tapered to provide linear relationship between the flow rate and the float position within the tube. The fluid enters at the bottom and passes upward around the float and out at the top. The float rises and falls depending on the flow rate, giving a variable area of the annular passage. The upward hydraulic forces that act on the float are in balance with its weight less the buoyant force; this will maintain the float position in equilibrium. The scale shows…
