Composite pipes widely used in water and sewage fields

Composite pipes widely used in water and sewage fields now days. As we all know that pipes are everywhere.

Countless miles of them, an essential but low-profile part of the infrastructure of human society. Multitudes of those pipes are associated with water and sewage, a sector that calls up large quantities of them each year.

Water and sewage pipes have variously been made from metals like lead (the word ‘plumbing’ is derived from the Latin word for this), iron and copper, plus concrete, clay, ceramic, plastic and even wood. Today, plastics are bearing a growing share of the load. Often these are unreinforced thermoplastics such as polyvinyl chloride (PVC), polypropylene (PP) and high density polyethylene (HDPE), but fibre reinforced plastics (FRP) play an important role where superior mechanical and corrosion resistance properties are required.

Reinforced plastic pipes have significant advantages. Mechanically, they are stronger and stiffer, for a given size and wall thickness, than unreinforced equivalents. They therefore need fewer supports and resist greater loads from surrounding soil,fiberglass chopped strand mat backfill, surface traffic etc. They can be pushed and drawn into position more forcefully during installation and may be buried deeper. They can be made strong enough to resist seismic loads, structural settlement and high internal surge pressures. A low coefficient of thermal expansion limits pipe movement in environments characterised by high temperature variations. FRP pipes are not damaged by frost.

In contrast to steel, a traditional pipe material, composite pipes do not corrode, taint water, suffer thermal stress or require cathodic protection; nor do they have to be surveyed periodically throughout life. Composites, appropriately formulated, can withstand even the highly acidic and sulphurous sewage environment. Smooth interior pipe surfaces present minimal impedance to flow and burst strength is generally sufficient to enable pipes to withstand pressure from clearing jets when blockages do occur. Jet pressures required to clear smooth-bore composite pipes are less than those needed for concrete and metal pipes.

120 ton GRP tanks were finished

120 ton GRP tanks were finished. Those were very huge tanks made by GRP and can be used for many different liquid. Plasticos Industriales de Tampico (PITSA), of Tampico, Mexico, was awarded an exceptionally challenging project in late 2007. PITSA accepted orders requiring the company to fabricate, within a few months time, four large diameter glass reinforced plastic (GRP) tanks at its factory and deliver them to the port to be transported by heavy lift vessel to a nickel extraction plant in the Pacific Rim. The tanks were 10 m inside diameter (ID) x 15 m, 14 m ID x 8 m and two of 14 m ID x 18 m.

All four tanks were domed top, flat bottom and designed for liquid fill, internal pressure of 5 kPa, vacuum of 3 kPa, wind and seismic. Vacuum of 3 kPa required that the flat bottoms be cored and the shells be stiffened. Vacuum also required the large domed tops to be significantly thicker than normal.

The 14 m x 18 m tanks were fabricated from Ashland’s Derakane 470 resin and Owens Corning’s Advantex E-CR glass reinforcement. The tanks were weighed by the cranes and were surprisingly close in weight due to the careful control of thicknesses. Each tank weighed about 120 tonnes.

GRP – the most practical material

The two big tanks will be used for both hydrochloric acid (HCl) and nickel chloride (NiCl2) service. GRP was the most cost effective material for these service conditions. While some of the high-end alloys can handle this combined service, the cost would have been significantly higher than GRP. In addition, GRP is relatively friendly for repairs and modifications, given the remote location of the jobsite. Welding exotic alloys has proven to be problematic in remote field locations due to site conditions and the lack of highly qualified welders. GRP laminations can be done using small hand tools and simple enclosures.

GRP is also versatile. GRP can be moulded into complex shapes, which is very helpful when the field operator encounters the need for a special fitting or pipe clip. Clips and brackets can be bonded to a tank without the localised heating created by welding. Metal tanks with coatings and linings typically cannot be welded without damaging the interior. In the case of GRP, clips and brackets can be laminated on, even with the tank filled.

Glass Fiber Reinforced Plastic (GFRP) Composites Market Opportunity in 2015 – 2021

The important FRP materials include glass fiber material and carbon fiber materials. These divide FRP into GFRP and CFRP. Glass fiber is a lightweight and durable

fiber produced from very fine fibers of glass. As compared to carbon fibers, glass fibers exhibit low brittleness and the fibers of glass used for their production are more cost effective. Moreover, as compared to metals, the glass fibers are possess better properties, both strength wise and weight wise. Furthermore, the glass fibers can be smoothly formed using different molding techniques.

Glass fibers are widely used as an important raw material for producing distinct types of composite materials. Manufacturing of glass fiber reinforced plastic (GFRP) composites, the largest class of composite materials, is the most important application of glass fibers and almost 90% of the reinforcements used in the composites industry are glass fibers. GFRP composites are extensively used in a diverse range of industries including wind energy, construction, automotive, aerospace, piping and anti-corrosive industrial equipments.

Application of Composites in Car Hoods and Bodies

Composite materials are used in many products, including the car hoods and bodies. The growing number of composites projects in the automotive sector was evident at the 2014 conference of the AVK Federation of Reinforced Composites and the co-located Composites Europe fair in Düsseldorf, Germany.

A car hood project was described by Günter Wolfsberger, product manager composites at automotive supplier Magna Steyr. He referred to production of Crushcore modules: these are polyurethane-based, honeycomb paper core, carbon or glass fibre composite-faced modules, which are produced using wet-pressed vacuum reaction injection moulded (V-RIM), and have Class A surface quality directly out of the mould tool.

Overall cycle time from lay-up to a ready-to-paint car hood is below 300 seconds, inclusive of final contour milling and insert mounting. A fully automated line working three shifts/day can produce 66,000 hoods/day, with possible optimisation to 111,000 hoods/day, Wolfsberger said.

Advantages over metal hoods include: better pedestrian head impact protection, higher overall stiffness, elimination of additional acoustic insulation and lower CO2 emissions through lighter weight – 33% less weight than an aluminium hood.

The hood project started in 2011 with BMW as first OEM partner, Rühl Puromer as PU supplier and Hennecke as PU machinery producer. The technology road map aims at further functional integration, leading to a “multi-functional front cover” in the 2020s. This could integrate antennae, air guidance channels, electrical conduits, filter boxes, hinges, mechanical tubing, 3D internal and external surfaces for brand emblems and energy storage.

Revealing more on the “multi-material composites” process, Rühl Puromer managing director Dr Ingo Kleba said Puropreg PU impregnates the honeycomb, while the Purorim casting system floods the carbon or glass fibre reinforced composite surface with PU, creating an easily paintable surface for serial production. Only one primer layer and two further paint layers are needed, followed by 90-110°C oven paint cure.

How to Compare and Choose Composite Materials

How to Comparing and Choosing Composite Materials

Various composite material are on the market, and they have various characteristics.How to comparing and choosing composite materials? Here we take a look at the pros and cons of the components: the resins and the fibers used to strengthen them.

There are three main recipes: polyester, vinylester and epoxy. Various flavours of each are available, depending on whether they are strengthened with glass, carbon or aramid fibers, and the particular application. For example, high UV (sunlight) tolerance may be chemically engineered using additives.

There are three main families in use at present: glass fiber, carbon fiber and aramid fiber (more commonly known as Kevlar, a trademark of the DuPont Corporation).

Glass fiber is by far the cheapest and most widely used, and works well with all three resin types, but it is relatively heavy. Carbon fiber is much lighter, as are aramid fibers.

Glass fibers (either in chopped strand or woven cloth form) are most commonly used with a polyester resin, whereas carbon fiber, as a relatively high cost strengthener, is most usually combined with epoxy resins.

A resin has to 'stick' to the fiber strengthener, and it is important to select a resin/fiber combination (particularly with carbon and aramid fibers) so that there is good adhesion and the fibers are properly bonded within the resin.

Composite Comparisons

In general terms, Kevlar mechanical properties are good in strength (double that of glass fibers) but very poor in stiffness, whilst the glass composite is ten times as stiff and half the strength.

Kevlar is very expensive compared to glass, so it is used where higher strength and elongation is needed.

Both aramid composites and GRP are good at handling repeated flexing cycles (such as in a boat hull), but carbon fiber has an unpredictable life when subject to repeated flexing.

GRP requires a considerably 'heavier' construction to achieve the strength of carbon fiber. Aramid fibers offer equivalent strength to fiberglass at a much lower weight, although abrasion resistance is lower.
