Rivets are a versatile fastening system used in a wide range of manufacturing and construction applications. A rivet is a metal fastener consisting of two parts - a cylindrical body called the shank and a head. The shank is inserted through holes in the materials being joined and the head is formed on the protruding end by crimping, hammering or pressing to create a permanent joint. Rivets come in different types, sizes and materials for diverse uses. Let's look at some of the common uses and applications for rivets.
Uses in Aircraft and Aerospace
One of the most extensive uses of rivets is in the aircraft and aerospace industry. Rivets are used to assemble the fuselage, wings, and other components in both civilian and military aircraft. Aircraft grade rivets are made from lightweight and strong materials like aluminum, titanium and specialty alloys. The integrity and reliability of rivets are crucial in aviation applications where structural failure could be catastrophic. Hundreds of thousands of rivets are used to join sheets of metal in the aircraft body. The fusilage of Boeing 747 for instance contains over 3 million rivets. Rivets allow for light and rigid airframe construction.
Rivets continue to be the preferred method of fastening in airplanes over other techniques like welding. This is because riveting minimizes cracks and weak points during manufacture and use. Rivets also withstand in-flight stresses and vibration better than welds over time. Aerospace companies conduct extensive testing to guarantee the quality of rivets used in aircraft. Other related applications include rockets, missiles, satellites and space vehicles which also employ rivets extensively in assembly.
Uses in Bridges and Steel Construction
Steel construction of bridges, towers, cranes, transmission towers and buildings relies heavily on rivets. Structural steel components are joined with tens of thousands of rivets in large construction projects. The Sydney Harbor Bridge contains over 6 million rivets in its construction. The reliability and strength of rivets are very important in these critical steel structures.
Hot riveting was the traditional method used in steel construction over a century ago. This involved hammering red hot rivets to form the head. Cold riveting is the modern technique, utilizing high strength structural rivets that can be installed at room temperature. The rivets have high clamping force to withstand shearing and vibration forces. Construction rivets come with large head dimensions for stability.
Uses in Manufacturing
The manufacturing industry employs rivets extensively for assembling products and parts. From cars, trucks, trains, ships to appliances, electronics and furniture - many products are held together by rivets. They are easy to install, provide tight fastening and can be used on different materials.
Pop rivets or blind rivets are especially popular in factories for mass production. These contain mandrels which are pulled to form the second head. Pop rivets can be quickly installed without the need to access both sides of a joint. Rivet setting tools pneumatically or hydraulically drive the rivets in a controlled manner. High speed robotic riveting further improves automation in manufacturing.
Uses in Railways and Mass Transit
Rivets have long been used in the construction of railway lines and mass transit systems. Railroad tracks are mounted on sleepers and cross ties using large numbers of durable rivets and bolts. Riveting provides the strong and reliable fastening required to withstand heavy loads and vibration from trains. Subway coaches, trams and other rolling stock also use plenty of rivets in their body frameworks.
Stainless steel coaches of modern metro trains contain thousands of rivets for optimal safety. Another application is the joining of steel girders in metro and rail bridges, tunnels, overpasses and station infrastructure. The movement of millions of commuters depends on the structural integrity of these riveted steel structures everyday.
Uses in Plumbing and Piping
Plumbers frequently employ rivets for assembling pipes, tubes, ducts, drains and other fixtures used in water supply and sewage plumbing. Copper rivets are common since they are corrosion resistant like copper pipes themselves. Stainless steel rivets also prevent rusting and are strong. Pipe hangers and supports are secured with rivets on walls and ceilings. Rivets provide leakproof joints critical for plumbing systems.
Large pipes and mains which transport gases, petroleum and industrial chemicals are also assembled using rivets. Hydraulic systems and oil rigs employed in the energy industry likewise require riveted pipes and fittings. Riveting is often preferred by plumbers and engineers over welding or adhesives for the durability it provides.
Uses in Boats and Ships
Shipbuilding has utilized rivets for centuries to fasten steel hulls because of their reliability in aquatic conditions. The water tightness provided by riveting helps prevent corrosion damage to the hull. Rivets also withstand stresses caused by waves and water pressure. Modern warships continue to rely on nearly a million rivets for hull assembly.
Rivets similarly hold together frames, decks and metallic components in cruise liners, cargo ships and submarines. Riveting permits warping of the hull which is difficult with welding. Rivets come with enlarged heads to bear hull loads. For small boats like fishing vessels, aluminum rivets are light and ideal against corrosion. Luxury yachts and racing boats also employ thousands of rivets.
Conclusion
From keeping airplanes safely airborne to holding bridges upright and assembling consumer goods, rivets continue to be an indispensable fastening solution. Their versatility, strength and ease of installation make rivets the choice of engineers, builders and manufacturers for diverse purposes. As construction and manufacturing techniques evolve, the humble rivet is set to retain its utility and wide ranging applications for the foreseeable future. CNC Milling
