  2. Why HDPE ? Good weather resistance, use for outdoor, Indoor & underground application. Good Flexibility, can be supplied in coil form. HDPE can be used up to - 45°C e. g. for chiller water, Refrigerator & Cold Areas. Good welding property. High stress cracking resistance to prevent slow and rapid crack propagation.

  3. Why HDPE ? Good Chemical resistance against aqueous solutions of salt, dilute acids & Alkalis. Good Corrosion resistance. Good Insulating property to prevent heat transfer. Light weight, Easy transport. High Impact strength.

  5. About PE63,PE-80 & PE-100 The HDPE pipes materials are classified with reference to their strength when subjected to internal hydrostatic pressure at 20°C during service life of at least 50 year. The minimum required strength (MRS) expressed in bar is used for designation of the pipe i.e. PE-63, PE-80 & PE-100

  6. Classification of PE pipes material 1 kg/cm² = 0.098 MPa = 0.980 Bar = 14.223 Psi = 98.066 KPa

  19. Type of welding in PE pipes Butt Welding :- The welding procedure involves accurate machine planning of the pipe ends followed by heating to the melting point of the pipe ends, which are then jointed together under pressure. The heating and cooling time, temperature and pressure are adjusted so that the physical properties of the original material is retained. Fusion Welding:- Use of this type welding, provided similar heating on outer surface of the pipe and inner surface of the fittings by heating devise then overlap both surface by external force. This technique use only small for diameter pipes. 3. Electro fusion welding:-The fittings is basically a double socket coupler with an electrical heating element within the bore. Two connection terminals are externally accessible for application of electrical heating energy to the element. When the two squared and scraped pipes ends are inserted into the coupler and the current is applied via a control box to the terminals the heating generated in the element fuse the two jointing surface together.

  29. WHAT IS WATER HAMMER? Water hammer (or hydraulic shock) is the momentary increase in pressure inside a pipe caused by a sudden change of direction or velocity of the liquid in the pipe. Water hammer can be particularly dangerous because the increase in pressure can be severe enough to rupture a pipe or cause damage to equipment.

  30. Example of Water Hammer There is a simple equation used to calculate the pressure created inside a pipe due to water hammer: Pwh = (0.070VL)/t + Pi Where: Pwh = Pressure resulting from water hammer V = Change in velocity of the liquid in the pipe L = Upstream pipe length t = Valve closing time Pi = Inlet pressure (pressure before hammer condition)

  31. Calculation for Water Hammer Let’s look at an example. Suppose we have an 800 foot long pipeline with water flowing through it at a rate of 4 feet per second. The pressure in the line at the downstream valve is 60 psi when the valve is closed over a period of: 10 seconds. What is the pressure increase due to water hammer? Pwh = (0.070VL)/t + Pi V = 4 ft/sec L = 800 ft t = 10 sec Pi = 60 psi Pwh = [(0.070 * 4 * 800)/10] + 60 Pwh = 82 psi (Water hammer increased the pressure by 22 psi)

  32. Calculation for Water Hammer • 1 seconds. What is the pressure increase due to water hammer? • Pwh = (0.070VL)/t + Pi • V = 4 ft/sec • L = 800 ft • t = 1 sec • Pi = 60 psi • Pwh = [(0.070 * 4 * 800)/1] + 60 • Pwh = 284 psi (Water hammer increased the pressure by 224 psi!) • The above two examples show how the water hammer pressure is affected by changing the valve closure time only while keeping all other variables unchanged
