Das Fass links ist oben steht: „Landschaft Island Reykjavik“
Aber das Recht ist: „Eigentum des britischen Erdöls“
Und das letzte Bild handelt von China.
Alle Hilfe ist willkommen; Egal, ob es sich um einen Link zu einer Website oder Informationen oder Informationen handelt, die jemand selbst kennt.
Ich beabsichtige immer noch, weiter nach Informationen zu suchen, aber hier sind weitere Notizen aus dem Zeitpunkt, an dem ich aufgeschrieben habe:
-
Der Grund für sie ist konvex, dass sie auf Tracks leicht rollen können
-
Auch weil sie, wenn sie miteinander liegen, nicht gegeneinander kämpfen (?)
-
Kein Schweißen, das Oberteil ist ein Stück entworfen und dann anziehen und dies wird zusammen gehämmert
-
Lieferung ist kein Schweißen, nur fertig? (Muss es herausfinden)
Ingenieure, die in Chemie gingen, viel Glück (werden möglicherweise auch meinen Vater nach Hilfe fragen, wer der Ingenieur ist, haha)

Early oil drums were riveted because welding wasn’t yet a viable method for creating the sealed, watertight joints needed for transporting oil. Riveting was a common and relatively robust way to join metal, and though it didn’t produce perfectly leak-proof drums and added cost and bulk, it was an improvement over wooden barrels and served its purpose until improved technologies like welded seams were developed.
Why rivets were used in early oil drums:
Technical limitations of the time: Welding technology for creating strong, reliable, and leak-proof seams on steel drums was not developed until about 1907.
A solution for oil transport: The introduction of steel drums in the early 20th century was a significant advancement over wooden barrels, which were prone to rot, leaks, and heavy to handle.
Durability and strength: While not perfect, riveting provided a more durable and robust container than wooden barrels for transporting oil, fuels, and chemicals.
Watertightness through cooling: In the riveting process, glowing hot rivets were hammered into place. As the rivets cooled, they shrank and compressed the overlapped metal, creating a tight joint that resisted the passage of liquids.
Drawbacks of riveted drums:
Leakage issues: Despite the tight seal from cooling rivets, early riveted barrels were not entirely leak-proof, often requiring constant maintenance.
Cost and weight: Riveted steel drums were heavy and expensive compared to wooden barrels.
Bulkiness: The early riveted drums were described as „clumsy“ and „bilged“ (bulging in the middle).
The transition to modern drums:
Welded seams: The introduction of welded seams significantly improved the leak-proof quality and reduced the cost of steel drums, making them much more efficient.
Manufacturing advancements: Modern manufacturing involves automated systems that use rollers to create interlocked seams called chimes, creating a highly durable and leakproof seal without rivets.
