The pipelines installed across landscapes in regions ranging from villages to cities, are essentially the carriers of resources like water and gas for industries and public utilities. Pipeline systems are also essential in installing efficient drainage systems. In a country like India, the relevance of having a well-built and constantly perfected and well-maintained pipeline system is very high. In a broad and diverse landscape as India has, it takes a dedicated and professional execution of laying down the lines that shall often be the sole source of resources like petroleum, water and gas. Refineries, fertilizer manufacturers, public utility establishments are all the beneficiaries of perfectly laid down pipeline systems.
The relevance of pipeline infrastructure is evident just from the consideration of petroleum industry. A sustained availability of petroleum products is essential to be prevalent across the country for which an effective and far reaching network of pipelines is essential. Dealing with such a significant infrastructure requirement is the kind of work the Everest Infra is keen to put its resources into, and emerge as a major name that will be associated with the domain.
The company uses top quality pipes of the following types;
Prestressed Concrete Pipes
This kind of pipes are useable in projects viz.
- Those involving distribution of high-pressure water transmission like in water supply and drainage
- Water supply in thermal power stations, refineries, etc.
- Sewer systems
- Storm water drainage systems
- These pipes with thick build are prestressed for withstanding water pressures of high volume.
Prestressed Concrete Cylindrical Pipes (PCCP)
This variant of prestressed pipes use steel in it optimally. The enforcement is steel rings with joints forged in very thick steel plates. The pipe type needs minimal maintenance too. Corrosion free and smooth conduction are a given due to the make of the interior involving steel and concrete.
Pre-stressed Concrete Cylinder Pipe utilizes steel usage to the max. By virtue of combined action of concrete, steel cylinder, and high tension wire, tremendous economy of steel usage in totality in the steel pipe is achieved in contrast to what happens in conventional methodology.
Conventional steel pipes tend to parry much after being affected by external loads due to their flexible nature. Such horizontal parrying is avoided by PCCP steel pipes as it utilizes the presence of soil flanking the sides that resists such anomaly. With constant supervision by expert contractors equipped with specialized apparatus, the desired compaction is achievable. PCCP can save on the additional laying cost incurred in conventional pipe installation. Inhibition of corrosion is another feature attached to PCCP which is achieved by virtue of the encasement in cement mortar which preserves the steel elements which stands protected in a highly alkaline wrapping.
The PCCP spells savings and cost effectiveness and has excellent testimonials of consistent, smooth conduction from many parts of the world.
Bar-wrapped Steel Cylinder Pipe
BWSC pipes are structurally thinner and is has thicker joints in steel welded at the ends. This type of pipe is tested hydraulically and lined centrifugally with cement mortar. On the cylinder, the wire is wrapped helically making sure there is proper contact with cylinder body. This is reinforced with cement mortar coating by process of high impaction. The gain comes in the form of several advantages over conventional steel pipes like flexibility, pipe strength and reliability.
The BWSC pipes can resist internal hydrostatic pressure as it is enforced with steel cylinder and with pretensioned rod wound helically in it. There is full scope of custom design by selecting steel-cylinder thickness, spacing and bar diameter. This can result in great savings. Besides, the interlocking of steel components enhances the structural integrity of the pipe. Inhibition of corrosion is another feature attached to BWSC pipes, which is achieved by virtue of the encasement in cement mortar which preserves the steel elements which stands protected in a highly alkaline wrapping.
BWSC pipes are thinner but stiffer than conventional steel pipes. The presence of tensioned rod effects the cost reduction when compared to other models of steel pipes. Reliable utilization of BWSC pipes have been seen around the world for purposes viz. water distribution pumping lines, sea water installations and sewage water disposals.
The conventional steel pipes are lauded for its potential to bear high capacity of water pressure and tension. This model maybe the least economic version of high end pipe alternatives, but is very much preferred for long range under-sea pipeline installations, and other exposed pipelines on land. This type of pipes could need extra concrete coating for assured protection and stability. Performance of steel pipes is a proven thing and the relevance do not diminish in the presence of its contemporaries, that may not be powerful enough to perform under extreme conditions as this version of steel pipes.
A major presence in hydro-electric projects, penstock pipes are capable of carrying water right from reservoirs to the turbines efficiently. Nevertheless, this type of pipes needs particular expertise from stages of installation, erection, fabrication and maintenance. Extremely precise and controlled management of heating temperatures is required during welding process of the steel used in such pipes. Techniques like radiography is typically used by experts who handle production of penstock pipes to ensure that no compromise on quality has happened. This will reaffirm its strength and durability for the long run.
