6 GRP Pipes GRP piping systems are time tested and it’s proven their durability and value in stony environments and brutal applications for decades Long life: It has a minimum life of 50 years. The smooth inner surface is maintained throughout the entire life of the pipe. Cost effective: 10 % -15 % cheaper than steel pipes & 20% - 30% percent cheaper than pre-stressed cement concrete pipes. Light weight: GRP pipes weights only 25 % as much as similar steel pipe and 10 % as much as similar concrete product. GRP pipes are light weighted, hence easier handling, faster installation and low transportation costs. The use of heavy equipment is practically eliminated.

7 GRP Pipes Dimension stability: GRP piping system can maintain the required critical tolerances of the most demanding structural and piping application. The materials need the most stringent material stiffness and dimensional tolerance. Strength to weight ratio: The GRP pipe has excellent strength to weight properties. When the ratio of strength per unit of weight is considered, GRP composites surpass iron, mild steel, HDPE (High-density polyethylene) and PVC (Poly Vinyl Chloride). Very low friction factor: Value of 'C' in Hazen Williams equation for calculation head loss due to friction in pipes is for GRP pipes against for steel pipes. Thus, the low friction coefficient and the hydraulic characteristics of GRP pipes lead to significant saving in pumping costs. Low maintenance cost: No maintenance cost due to absence of corrosion, zero replacement.

8 GRP Pipes Corrosion resistance:
GRP piping is having anti-corrosion system in both inside & outside. These pipes has been used for handling dilute acids, saturated brine, organic solvents and other corrosive chemical but there is a zero corrosion as result additional lining and exterior coating are not required. Low thermal conductivity: Low thermal conductivity of GRP pipe not only causes low temperature losses but also in many cases eliminates condensation or the need for additional thermal insulation. Installation benefits: GRP pipes are light weight, hence it is easy for installation. These can be manufactured up to 12m long to speed up the installation and eliminates up to 75% of the joints compare to any other materials, hence handling & installation is easier than any other products. GRP pipes are meager heaviness hence it’s reduce the expensive installation, labor and machinery expenditures..

9 Transportation and handling
Prior to unloading of pipes from trailers, all items shall be inspected for any visual/transportation damages. From the lay-down area to the trench site, the pipes shall be transported through trailers or by using of Hydra. Single pipe must be unloaded and handled separately (one at a time) by using pliable straps, wide fabric straps, slings or ropes to lift single pipe. (Not using Steel Cables or Chains). Individual pipe can usually be lifted with a single sling. At any time during handling or installation of the pipe, any damage such as cracks, de-lamination or fracture occurs, the pipe should be repaired before the section is installed.

10 Transportation and handling of GRP Pipes
Transporting Pipe Lifting pipe at one support point Lifting pipe at two support points

11 Storage of GRP Pipes Pipe is generally stored on flat timbers to facilitate placement and removal of lifting slings. The support timbers should have sufficient width to prevent point loads. The maximum stack height is typically 8 ft. When stored directly on the ground, the pipe weight should not be supported by the bell, coupling, or any other joint surface. The pipe should rest on plane ground and should not rest on rocks, boulders, or other hard debris that may cause a point load sufficient to gouge, crack, puncture. The pipe interior and all joining surfaces should be kept free of dirt and foreign particles.

17 Tools for Butt & Wrap Lamination Joints
Measuring tape + pipe fitter's wrap-a-round + marker pen Cleaning-rags Angle grinder with diagrit or carborundum cutting disc (grain 24), a handsaw 24 teeth/inch, jig saw with a 14 teeth/inch blade Angle grinder + sanding disc + flexible support disc Resin, hardener and glass reinforcement + a pair of scissors Gloves, brushes, rollers, dust masks in quantities as mentioned in the fit and laminating sets, a pair of safety glasses Shelter (depending on the weather circumstances) Hot air gun (paint stripper gun), digital temperature gauge, gas burner, field oven, heating blanket, variable energy control (rheostat) Pipe clamp, bench and rubber strips (under chain clamp). Generator

18 General Safety Recommendations
The practical or possible fabrication area is to be setup to perform as much of the fabrication work. Local exhaust ventilation should be provided at areas of cutting and tapering to remove airborne dust and fibers. General dilution ventilation should be provided as necessary to keep airborne dust and fibers below the applicable exposure limits and guidelines. Work area should be kept clean, including floor or other horizontal surfaces. Rinsing with water or sweeping with brushes or brooms (using floor sweep) is recommended. Brushes should be used to remove residue from shaved surfaces. Always refer to the Material Safety Data Sheet (MSDS) prior to working with unfamiliar materials or if there are questions concerning the contents of the fiberglass pipe.

19 General Safety Recommendations
Barrier creme may be applied to the skin in areas, which may be exposed to shavings prior to beginning work. Clean clothes should be worn each day. Do not wear clothing that has not been laundered to begin a work shift. More frequent changing may be required by conditions. Long sleeved shirts or work suits should be used. Gloves with elastic cuffs should be worn at all times. Replace worn or contaminated gloves as necessary. Gloves with flared, stiff cuffs act as a gathering funnel for shavings. Pant legs should be worn outside work boots. If necessary for safety purposes, the pant legs can be taped to fit closely to the boot. Over-the-calf socks can be used to prevent chafing of the boot on the skin.

20 Personal Hygiene Wash exposed skin with soap solution (liquid soap preferred) and cool water. Use washcloth with “brushing” motion to remove dust or fibers. Do not scrub the Skin. This could result in the fibers being imbedded into the skin. Rinse thoroughly with clean, cold water. Apply lotion or cream to skin (non-detergent formulas such as baby lotion) to soothe Irritation or prevent further immediate irritation.

21 Field Hydro Testing of Above Ground Pipes
Fill with water at the lowest point in the line using a small diameter branch connection and vent the trapped air at the highest points. Long straight sections may be vented using an inflatable ball or foam pig to expel any air and impurities. After filling, the line must be pressurized gradually at 0.8 times working pressure dependent. on the system and must be maintained for 24 hours allowing the pipe system to set. After the system is stabilized, the pressure must be raised gradually to the agreed field test pressure.

22 Causes for pressure drop
Temperature change - day as well as night Leakage of valves, fittings, hydrants, etc… Leakage of gaskets Dirt at sealing ring Wrong installation of O-ring (slip ring) Pipes or fittings insufficiently blocked in the trench resulting in displacement Air lock Leaking test equipment Leaking joint (adhesive bonded, rubber seal or laminated joint) Leakage in fittings Leakage of the pipe as result of damage (cracks) Settlement of the pipe system
