Glass Reinforced Polymer Pipe Introduction

Hi-Tech Composite Division has professional expertise at its core GRP pipe manufacturing Experience in water transmission pipe lines process and pressure system. The ethos behind composite pipe team of Engineers is to work alongside the client, the consultant and the contractor.

Fiberglass pipe is made from glass fiber reinforcements embedded in, or surrounded by, cured thermosetting resin. This composite structure may also contain silica, aggregate, granular, or platelet fillers; thixotropic agents. By selecting the proper combination of resin, glass fibers, fillers and design, the fabricator can create a product that offers a broad range of properties and performance characteristics.

Over the years, the diversity and versatility of materials used to manufacture fiberglass pipe have led to a variety of names for fiberglass pipe. Among these are reinforced thermosetting resin pipe (RTRP), reinforced polymer mortar pipe (RPMP), fiberglass reinforced epoxy (FRE), glass reinforced plastic (GRP), and fiberglass reinforced plastic (FRP). Fiberglass pipes have also been categorized by the particular manufacturing process—filament winding or centrifugal casting. Frequently, the particular resin used to manufacture the fiberglass pipe—epoxy, polyester, or vinyl ester—has been used to classify or grade fiberglass pipes.

Regardless of the many possible combinations, the most common and useful designation is simply "fiberglass pipe." This name encompasses all of the various available products and allows consideration as a unique and general class of engineering materials.

Manufacturing Process

FIBERFUSION^TM pipes are manufactured using the continuous advancing mandrel process which represents. The state of the art in GRP pipe production. This process allows the use of continuous glass fiber reinforcements in the circumferential direction. For a pressure pipe or buried conduit the principle stress is in the circumferential direction, thus incorporating continuous reinforcements in this direction and not just chopped discontinuous roving. Yields a higher performing product at lower cost.

Using the advance technology, a very dense laminate is created that maximizes the contribution from the three basic raw materials, namely glass fiber, silica sand aggregate and thermosetting resin (unsaturated Polyester Resin) Both continuous glass fiber roving and chopped roving are incorporated for high Strength and axial reinforcement. A silica sand aggregate is used to provide' increased stiffness with placement near the neutral axis in the core. Thermosetting resin, delivered through a dual resin delivery system give the equipment the capability of applying special inner resin liner for severe corrosive applications while utilizing a less costly resin for the structural and outer portion of the laminate. The materials are applied to produce series of layers which give both pressure resistance as well as pipe stiffness.

Product Advantages

Features & Advantages of GRP Pipe as A Material of Choice:

By virtue of its superior material characteristics, GRP pipes have become the Ultimate choice replacing steel, DI and Concrete pipes for transporting different Process fluids, sea water, raw water and potable water for different underground and aboveground applications. <

The single most reason why people go for GRP is the total corrosion resistance that this material offers. Well-engineered GRP pipelines can be totally forgotten after installation for its life period without cathodic protection or periodic maintenance and for this reason, GRP pipelines are called as "ZERO-MAINTENANCE PIPING".

International Codes and specifications are available for GRP pipe design, construction, testing and installation. All service requirements are met by the GRP Pipes in total by suitable and appropriate design.

On the cost front, with optimum engineering and productivity matching the best of industries worldwide, we are able to compete with steel, ductile iron and other Conventional piping material.

The Prime advantage of GRP pipes are given below:

Application

Growing awareness of the operational cost savings and Superior corrosion resistance offered by glass reinforced Plastic pipe made by Hi-Tech will result in its widespread application for the following:

Finish Product Long Term Qualification Tests:

A. Strain Corrosion Testing:

A unique and important performance requirement for GRP gravity/pressure pipe used in sewer applications is the chemical testing. of the pipe in a deflected or strained condition. This strain corrosion testing is carried out in accordance with ASTM D3681, and requires a minimum of 18 ring samples of the pipe to be deflected to various levels and held constant. These strained rings are then exposed at the invert of the interior surface to 1.0N (5% by weight) sulfuric acid This is intended to simulate a buried septic sewer condition. The time to failure (leakage) for each test sample is measured. The minimum extrapolated failure strain at 50 years, using a least square regression analysis of the failure data, must equal the values shown for each stiffness class. The value achieved is then relatable to the pipe design to enable prediction of safe installation limitations for GRP pipe used for this type of service. Typically, this is 5% in-ground long-term deflections.

B. Hydrostatic Design Basis - HDB:

Another important qualification test is the establishment of the Hydrostatic Design Basis -HDB. This test is carried out in accordance with ASTM D2992 Procedure B and requires hydrostatic pressure testing to failure (leakage) of many pipe samples at a variety of very high constant, pressure levels.

As in the previously described strain corrosion test, the resulting data is evaluated on a log-log basis for pressure (or hoop tensile strain) vs. Time to failure and then extrapolated to 50 years The extrapolated failure pressure (strain) at 50 years, referred as the hydrostatic design basis (strain) or HDB, must be at least 1.8 times the rated pressure class (strain at the rated pressure) (see Figure 3.2). In other words, the design criteria require that the average pipe be capable of with standing a constant pressure of 1.8 times the maximum operating condition for 50 years. Due to combined loading considerations, that is the interaction of internal pressure and external soil loads; the actual long-term factor of safety against pressure failure alone is higher than 1.8. This qualification test helps assure the long-term performance of the pipe. in pressure service.

Jointing System for GRP Pipes:

Categories:

GRP pipe joints have two general categories:

Restrained Joints:

Pipe joints capable of withstanding internal pressure and axial load due to internal pressure.

• GRP Flanged Joints
• Butt & Wrap Joint
• Rubber Seal Lock Joint (With Rubber Sealing Rings and a Locking Key)

GRP Flanged Joints

The standard bolt pattern to which our flanges are manufactured is in accordance with IS02084. Other bolting dimension systems such as AWWA, ANSI, DIN and JIS can also be supplied. Loose and fixed flanges are available for all pressure classes. Contact molded flanged joints.

Double Bell Coupler with Rubber Sealing Rings:

Double bell coupler is employed to connect two GRP pipes, which are mainly used for underground application. Double bell coupler has grooves inside the coupler to retain elastomeric seals that shall be the sole element of the joint to provide the water tightness. This flexible joint allows for axial movement of the pipe in the coupler and some angular deflection. The both ends of GRP pipe will have spigot, which will match with the coupler.
