What is a riveted boiler? Where is it mainly used?
Thread Content
Boilers are generally classified by pressure, function, or structure. Today I saw a riveted boiler – by what criterion is it classified? What are the characteristics of this type of boiler? It would be best to have images to illustrate it
For riveted boilers, it is only the boiler’s shell that needs to be riveted; this has nothing to do with the boiler’s pressure. Riveting is used in construction, boiler manufacturing, railway bridges, and metal structures, among other fields. The main advantages of riveting are: simple process, reliable connection, vibration resistance, and impact resistance. Compared to welding, its disadvantages are: a bulky structure, rivet holes that reduce the cross-sectional strength of the joined components by 15%–20%, and lower economy and tightness in riveting compared to welding. Compared to bolted connections, riveting is more economical and results in less weight. However, with the development of welding and high-strength bolted connections, the use of riveting has gradually declined. It is still employed in metal structures subjected to severe impact or intense vibration loads, or in situations where welding techniques are limited, such as in crane frames, railway bridges, shipbuilding, and heavy machinery. Nevertheless, riveting remains the primary method used in aviation and aerospace vehicles. Furthermore, rivet connections are sometimes also used for joining non-metallic components (such as the connection between the friction pads and the brake shoes or bands in brakes).
Happy holidays! I really haven’t met you before
I heard it from the experienced master. Haven’t seen it.
I heard from an experienced worker in his 70s that **during that time, boilers were made using hammers and rivets; it was essentially a riveting process. It sounds confusing right now.
That’s right! It feels like it’s a car that burns charcoal
It should be made by buying steel plates and using a sledgehammer and rivets. Back then, holes were drilled using hand-cranked drills. I just can’t figure out how it was made at all.
A hand drill – I’ve never seen something like that either. Is it like the hand drill used by old-fashioned carpenters? How is it possible to drill through steel plates?
Where can I find a hand drill? There are indeed hand drills that can drill steel plates; you can search for it on Baidu
Hehe, yes, maybe in N years, when children see trains and we tell them that the engine of a train runs on coal, they will be confused just like that.
