The Application of Fiberglass Pipe

The Fiberglass Pipe is a special fiberglass sleeve which is processed by a high temperature setting process after being woven into a tube with glass fiber.

With the acceleration of China's urbanization process, facing the balance and protection of population, resources and environment, governments at all levels have increased their investment in urban infrastructure year by year. In combination with the needs of advanced science and technology, the varieties and specifications of pipes and fittings are continuously enriched. The output is constantly increasing, the quality is constantly improving, especially the development of plastic pipes is faster, and it has become a hot spot for investment today. A fiberglass pipe is one of them.

Fiberglass pipes have been widely used in petroleum, power, chemical, paper, urban water supply and drainage, factory sewage treatment, seawater desalination, gas transportation and other industries with their unique advantages.

Future Development

Architectural and engineering firms are now able to use computer software programs developed to enhance the design of FRP piping systems. The program includes liquid flow analysis, gas flow analysis, free span analysis, thrust block design, chemical composition and installation information. The program makes it easy to step through complicated calculations and analysis when designing a new FRP piping system or for troubleshooting an existing FRP piping system.

Oil & Gas Production Industry:

The oil and gas production industry will be requiring higher pressure rated and larger diameter piping to control corrosion problems in produced fluid lines (It is not uncommon to “produce” and treat seven barrels of water for each barrel of crude oil brought out of the ground). In addition to solving corrosion problems, FRP piping can be designed with a flame retardant additive to reduce flame spread for non-critical areas or in critical areas, be coated with an intumescent paint or insulated with an intumescent material i. e., the paint and coating expands to form incombustible foam insulation. This latter system will maintain the serviceability of the piping for a minimum of three hours under flow conditions. 

FRP firewater protection piping is solving weight problems when designing offshore oil production platforms. Weight savings in the design of a platform can save the owner from $2.00 to $4.00 per pound in construction costs by reducing the weight of the support structure (e.g., savings up to 750 tons). In areas classified as hazardous, FRP piping can be made with conductive fibers, co-mingled with the glass fibers, to provide electrical conductivity of the material to ground the system and prevent potential build-up of static charge.

Municipal and Industrial Pipe Applications:

1.Trenchless Piping: 

Trenchless piping is a rapidly growing technology where micro-tunneling for new piping and slip-lining for rehabilitating existing piping do not disturb roadbeds or other aboveground structures.

2.Micro-tunneling: 

While tunnel boring has been used on large tunnel projects, micro-tunneling is a new application for trench-less piping. In micro-tunneling the FRP pipe is hydraulically jacked and pushes the cutter head through the substrata. It takes hundreds of tons of jacking pressure to push large diameter piping distances of hundreds of feet. For example, 18 inch diameter FRP pipe can be jacked at pressures up to 90 tons and nine foot diameter FRP pipe at pressures up to 1,750 tons.

In the past, stainless steel sleeves have been used as reinforcement around concrete pipe joints to withstand hydraulic jacking pressures. However, FRP sleeve joints are proving to be a cost-effective replacement for stainless steel used in concrete pipe jacking.

FRP pipe and joint systems are proving to be more cost effective than their concrete counterpart because of the smoother outside surface and lighter weight. These features significantly reduce the jacking pressure required and permit jacking longer runs than concrete, reducing installation costs and time.

3.Slip-lining: 

Slip-lining is a trench-less method of rehabilitating an existing pipe with a minimum of excavation. New and rehabilitated sewer and drainage pipes are no longer limited to relatively small diameter FRP slip-lining methods. Centrifugal cast FRP pipe technology has advanced and yields a machine-made pipe with close outside diameter tolerances in diameters up to 120 inches. 

The light weight and smooth outer surface permits jacking the pipe inside an existing pipe, thus rehabilitating leaking concrete sewer pipes. This system of rehabilitation minimizes the jacking pressures required to push the FRP pipe through the existing concrete pipe and is done even as sewage flow continues. For example, a trench-less project is underway to rehabilitate 6,000 feet of 102 inch sewer in Los Angeles with a minimum of excavation by using nine foot diameter FRP pipe.

Industrial Applications: 

Chemical processing typically involves piping exposure to such chemicals such as acetone, methylene chloride, hydrochloric acid, ethylene dichloride, phenol, toluene, xylene, ethyl acetate and methyl acetate. Specialty metals such as titanium are typically used for resistance to such chemicals, but are prohibitively expensive. However, resin selection such as furan based materials are extremely solvent resistant and cost-effective.

New Energy Vehicles:

With the fiery heat of new energy vehicles, fiberglass pipes have ushered in another big application boom.First of all, the new energy automobile motor has higher requirements for its temperature resistance grade, and at the same time it needs certain wear resistance, cutting resistance and certain mechanical toughness. The fiberglass pipe becomes the first choice for the insulation sleeve of the new energy automobile motor. The motor of the new energy vehicle will use a large number of 1.5KV fiberglass casings, 4KV fiberglass casings, and high-temperature resistant silicone rubber heat-shrinkable pipes, among which the highest temperature-resistant pipe is used.
