Glass Reinforced Epoxy (GRE) materials are a substitute to carbon steel pipes that are extremely valuable particularly for eroding. Aggressive and normal surroundings. High power fiberglass and amine preserved epoxy resin treated below intermittent thread winding procedure is the equipment used in GRE pipes. They are made by numerically measured machines on a mandrel as per the cross section thread zigzagging procedure. GRE pipes are appropriate and are useful at power plant piping, down whole casing as well as tubing, plant process piping, oil and gas flow lines, potable water delivery arrangements, offshore applications and so on. GRE pipes are very much light in weight, simple to grip and connect. The current conductivity of these pipes is less as compared to steel and so insulation and heat loss as well as the expense is minimalized. They even have a smooth interior surface that allows extraordinary pipe flow volume and decreases resistance. GRE pipes is easy to install and is maintenance free.
GRE pipes offers an excellent preparation of biochemical resistance, current resistance, larger motorized possessions that is attained by the collection of extremely execution mechanisms and a correctly intended construction. The main raw materials applied for this is fiber glass, Inner liner contains of C-glass Covering and Amine Cured Epoxy resin for larger biochemical resistance and this would improve scrape resistance. The physical coating contains of Amine Cured Epoxy resin and E- glass. Outside Liner is of mastic layer with structure same as the physical layer. GRE Pipes could be applied for medium of temperature. The diameters of pipe shaped ranges from 25mm to 2000mm. The major difference between the GRP and GRE is the pitch applied for attachment the glass fiber. GRP pipe uses Isophthalic Resin while GRE pipe uses Epoxy Resin. These pipes are applied in industrial application, where they can endure greater temperature as compared to GRP pipe.
What is piping Specifications?
GRE pipe specification is practical documents that are made by many companies to address extra requirements appropriate to an exact product or submission. Piping offers precise or extra requirements for the supplies, mechanisms or facilities that are outside the code and normal supplies.
Why is Specification needed?
1. It lets a buyer to comprise special supplies according to the service and design circumstance.
2. It even lets modification of the product.
3. The need in the specification is Obligation wile meeting the requirements.
What is Piping Components?
Piping Components are motorized rudiments appropriate for connecting or collecting a pressure close-fitting fluid covering high-pitched classification. Piping Components comprise of tubes, pipes, fittings, gaskets, flanges, valves, bolt-nuts, expansion joints, traps, hose pipes, separators, strainers, control valves, security valves, spectacle blinds, and blind flanges as well as drip rings and so on.
Benefits of GRE pipe
1. Lightweight and great strength:
GRE pipes are made of hoop tensile strength of 300-375 MPA, when associated with PVC pipes. Its makings need less of heavy machinery and there is no requirement of bonding agents, welding and bolting. It has an amazing mechanical power and can endure light to reasonable weight. Furthermore, GRE pipes are less in weight as compared to mild steel, ductile iron as well as HDPE pipes. The weight safeguards easy treating of equipment, simple installation and transportation. These makings create GRP pipes hard-wearing, consistent and inexpensive than old-style materials.
2. Surge pressure
GRE pipes are normally manmade that comes with 6 meters to 12 meters. The greater stiffness and extraordinary compressive volume of load of GRE pipes stops the overflowing of pipes because of the pressure of to water. They are made with a less wall thickness that creates it to become easy to bury them with simple routine approaches with informal treating of profound covers. They are resilient to scratch and cracking, as well as leak-free linkages that assures less treatments, zero infiltration and no groundwater contamination.
3. Hydraulic efficiency:
GRE pipes comes with a smooth interior surface that offers outstanding hydraulic features and extraordinary flow volume and less resistance. They even work nicely for outstanding driving thus it saves electricity. These are even less on electrical and thermal conductivity because of no exterior insulation of pipes. The interior heat of GRP pipes are persistent because of their exclusive current properties.
GRE pipes are extraordinarily versatile, that permits them to accommodate length in keeping with the applying needs. The graceful and dimensionally consistent surface makes the pipe length adaptable because of the less range of bends and straightforward adjustability. Makers also can make a choice from a large vary of sizes, pipe lengths and outline as per demands. This can be the rationale why GRE pipes is most well-liked for construction within the seismic zones.
