Pressure vessels are very important components of the industry and are closely associated to daily life. They are structures such as pipes, bottles and vessels capable of holding internal pressure. Every industry small, medium, large or very large needs pressure vessels. Boilers are used for producing power. There are heat exchangers used in many industrial applications. Take the name of any industrial sector there oil tanks, pipelines, compressors for supplying compressed air for cleaning, pnuematic systems for instrumentation, pneumatic conveying sytems for transportion of solid, liquid and gaseous materials in the industry. Oil and gas industry, aerospace industry, marine industry, refrigeration and air conditioning systems use pressure vessels.

Safety issues with pressure vessels

                Pressure vessels are associated with lots of safety risks. Any explosion of pressure vessel can be very dangerous to the workers and plant and machinery. There have been serious accidents in power houses, cement plants, steel plants, chemical plants and aerospace industry resulting lots of losses of human lives and to the industrial assets. Airplane cabins is a familiar examples of the pressure-containing structures. The atmosphere inside the cabin relative to the thin air outside is a serious threat to the airplane if cracks are developed. Number of fatal tragedies have occurred from this problem. The famous tragedy is of disintegration of Comet aircraft in flight in the 1950s is still fresh in memory. The loss of a 5-meter section of a roof of the first-class section of an Aloha Airlines B737 in April 1982 is another important case showing the gravity of the dangers associated with the pressure vessels.

Pressure vessel suppliers are very concerned to determine the stresses and deformations in structures such as these as it will be the crucial measure for the safety of structures as the first step in designing against failure.

Need for industry standards, code and enforcing agencies

                The gravity of the consequences of damages to human life and property and the inconvenience they cause to the society is well understood by the manufacturers of pressure vessels. They are keen to adopt foolproof design of systems and components, selecting the right materials of construction and latest technologies in manufacturing the safe pressure vessels. Strictly following the industry standards and codes involving competent inspections in obtaining the right materials, inspection during the manufacturing and final inspection after the product is ready for use are of utmost importance for the manufacturers of pressure vessels. The safety of pressure vessels is not the concern of only the manufacturers of the pressure vessel but is for every one involved in the process like suppliers of the materials, equipment, instruments, testing agencies and enforcement bodies.

car pollutionWith the rising population and growing economies the transport sector is faced with number of challenges like increasing number of vehicles on the roads, high fuel consumption, need for alternative fuels for use in the transport vehicles and more important the adverse impact on the environment. Almost all the major cities in all the countries face the challenge to meet the growing need for transport vehicles in the cities. The number of vehicles on the roads is increasing every year resulting in traffic jams, rising air pollution more accidents. Some of the major cities of the world like Delhi in India, San Ramon in California in USA, the city of the most famous project ‘The Silicon Valley Project’ and London in UK are experiencing the rising number of vehicles on the roads.

Government in some of the countries are forced to take immediate remedial steps to replace the petrol and diesel run vehicles by vehicles run on CNG fuel. The problem is becoming more serious in major cosmopolitan cities due to continuous inflow of people from other cities for various reasons like increased job opportunities, opportunities for business and trade and abundant educational facilities. This has made it essential to disperse the offices and commercial centers, hospitals and other day to day facilities to different locations throughout the cities thus increasing distances to travel. Due to rising cost of living in the metropolitan cities, a large number workforce lives in satellite cities and travels every day to the metropolitan cities for work adding to the number of transport vehicles on the road.

gas running busesAccording to a report by Hexagon Composites, there is rising demand for the natural gas-powered buses and commercial trucks across developed economies around the world due to low prices for CNG gas. The cost of natural-gas fuels in North America is about 40 percent lower than diesel, per diesel gallon equivalent. Composites Forecasts and Consulting (Mesa, AZ, US) brought out in its study in 2013 that high-pressure gas storage vessels is going to be one of the fastest-growing markets for construction of types of pressure vessels representing global sales of more than US$2 billion. Bulk transportation of compressed natural gas (CNG) products, and fuel storage in passenger cars, buses and trucks with powertrains dependent on CNG and hydrogen alternatives to gasoline and diesel are going to be the main market potentials for the composite-reinforced pressure vessels.

Composites Forecasts and Consulting reported the number of natural gas-powered vehicles (NGVS) in the world at around 10 million five years back. These NGVs included cars, trucks, buses, and fork-lift vehicles. This number became more than 20 million by the year 2013 and is expected to be more than more than 65 million by the year 2023. Major junk of these NGVs (94 percent) are likely to be fitted with high-pressure fuel storage systems.

pressure vesselThere is great opportunity for the manufacturers of high pressure vessels to meet the growing market demand. Along with the large opportunities in the future market for the high pressure vessels, the high pressure vessel manufacturers have lots of challenge to remain competitive in the market. Adoption of latest materials, latest technologies and manufacturing processes are going to be crucial for remaining competitive. It is the quality, cost and availability of the high pressure vessels which will decide a place for the high pressure vessel manufacturers in the competitive market.
