Rivets have been used for thousands of years in applications ranging from boilers and ships to bridges and skyscrapers. Today, rivets continue to be a popular choice for joining materials in many industries due to their strength, reliability, and ease of installation. Here are some of the top uses for rivets in modern manufacturing and construction.
Aircraft and Aerospace Applications
Aircraft construction relies heavily on rivets to assemble major components and provide structural integrity. Rivets are used to join the fuselage skins to frames and stringers, attach wings to fuselages, and fasten control surfaces. Structural rivets for aircraft are typically made from lightweight aluminum alloys, titanium, or specialty steels.
Rivets are preferred for aircraft assembly because they have high shear strength to withstand dynamic flight loads. Riveting also eliminates a need for welding or toxic adhesives. The hole-filling property of rivets provides a smooth surface crucial for minimizing drag. Lastly, rivets do not loosen over time like screws and bolts, critical for flight safety.
Rivets are ubiquitous in automotive manufacturing for assembling body panels, doors, hoods, and roofs. Self-piercing rivets (SPRs) allow direct joining of dissimilar materials like steel and aluminum without pre-drilled holes. This simplifies auto construction and accommodates different thermal expansion rates. SPRs also dampen noise and vibrations for a quieter ride.
Structural rivets reinforce auto frames and subframes. Large semi-tubular rivets affix trucks beds to the chassis. Blind rivetsare ideal for installing panels where access is only available from one side. Rivets lend themselves well to automated fastening in mass production. Lastly, rivets permit simpler repair versus welding if body panels get damaged.
Plumbing and Pipe Connections
Rivets provide a strong method for joining pipes, valves, and plumbing fixtures. Tubular rivets are commonly used to make watertight connections in industrial pipework. The domed rivet heads distribute clamping force for consistent sealing. Installation is fast and requires no special tools other than an air hammer or hydraulic rivet squeezer.
Blind rivets are popular for making pipe joints in constrained spaces. Refrigeration units, boilers, heat exchangers, and process equipment all utilize riveted plumbing. Rivets can join dissimilar metals like copper and steel pipes. They also safely seal high pressure steam lines and caustic chemical flows.
Almost all aspects of railroad construction use rivets, including fastening rails to ties, assembling track switch components, and building locomotives, freight cars, and passenger cars. Early railroads relied extensively on manual hot riveting. Modern railroads use more automated cold riveting and self-piercing rivets.
Rail engineers prefer rivets for their vibration resistance and strength in shearing, tension, and compression. Riveting also accommodates temperature-related expansion and contraction of long steel rails. Many railroad rivets have enlarged heads to improve load distribution. Lastly, installing and removing rivets for repair is simpler than comparable welded or bolted connections.
Shipping and Boatbuilding
Ship hulls, barges, offshore rigs, and other marine vessels are fastened together using billions of rivets. The extensive riveting provides exceptional longitudinal strength to resist buckling and withstand slamming loads in high seas. Large heads with deep countersinks create a hydrodynamic outer shell by smoothing welds and joints.
Blind rivets allow installation from only one side of a plate - essential for sealing watertight compartments. Clinched lock bolts provide the benefits of rivets while permitting disassembly. Many marine rivets feature corrosion resistant alloy or stainless steel construction. Finally, rivets evenly distribute stresses across joints between dissimilar metals to prevent cracking.
Building and Construction Applications
The versatility, strength, and durability of rivets make them ideal for diverse building and construction projects. Structural rivets assemble beams, girders, columns, and trusses for high-rise buildings, stadiums, and bridges. FaÃ§ade panels, siding, ducting, decking, and roofing often use specialized rivet types. Self-drilling rivets quickly fasten to steel without pre-drilling concrete.
Countersunk rivets create flush exterior surfaces crucial for architectural aesthetics. Drive rivets attach gutters, downspouts, and flashing against water infiltration. Blind rivets facilitate fast interior finishes and suspended ceilings where backside access is unavailable. Lastly, tubular rivets anchor bolts, conduit, pipes, and heavy equipment to concrete foundations and slabs.
Many common household and consumer products rely on rivets for fabrication and durability. Kitchen appliances like dishwashers, refrigerators, and ovens utilize rivets in their casing, hinges, handles, and internal components. Rivets assemble outdoor grills, patio furniture, storage sheds, and recreational vehicles. Eyeglass frames, hand tools, bicycles, and numerous other consumer goods all benefit from riveted construction.
Blind rivets are particularly useful for consumer products when an invisible fastener is preferred. The reliability, corrosion resistance, and cost-effectiveness of rivets make them ideal for mass-produced consumer goods. Manufacturers can easily install rivets via automation or semi-skilled labor. Relative to welding and adhesives, riveted goods are simpler to service or disassemble for recycling.
Rivets have proven their mettle for thousands of years in all manners of construction and manufacturing. Modern innovations such as blind rivets and SPRs expand the application range even further. New specialty rivet alloys and profiles continue to evolve as well. With their unparalleled combination of strength, economy, and practicality, rivets will undoubtedly remain integral components across countless industries for the foreseeable future.
