Bombe - Bombe (English spelling) Bomb English

A steel pressure-resistant container for storing, transporting, and using compressed gases such as hydrogen, oxygen, liquefied natural gas (propane gas), and liquefied petroleum gas. Thin containers assembled by welding are used to store liquefied gases with relatively low pressure, such as ammonia, propane, and butane. On the other hand, thick seamless containers with high pressure resistance are used to store high-pressure gases of about 150 atmospheres, such as hydrogen, oxygen, nitrogen, argon, helium, and methane. There are large ones, usually about 7 cubic meters (gas volume converted to 1 atmosphere) and 1.5 meters high, and small ones, about 1.5 cubic meters (gas volume converted to 1 atmosphere) and 1 meter high. The color of the exterior paint of a cylinder is determined by the type of gas to be stored, to prevent danger due to mistakes ( table ). To use a gas that you like from a cylinder, you attach a pressure reducing valve to reduce the pressure and take it out. There are low-pressure and high-pressure pressure reducing valves, and in either case, the pressure and flow rate of the released gas can be fine-tuned. Keep cylinders away from direct sunlight, fire and vibration, and use them secured to a stand or chain to prevent them from falling over.

Japanese:

水素、酸素、液化天然ガス(プロパンガス)、液化石油ガスなどの圧縮ガスを入れ、それを貯蔵、運搬、使用の目的に使うための鋼製の耐圧容器。比較的高くない圧の液化ガス、たとえばアンモニア、プロパン、ブタンなどを入れるのには、溶接などで組み立てられた厚さの薄い容器が用いられる。一方、150気圧ぐらいの高圧ガス、たとえば水素、酸素、窒素、アルゴン、ヘリウム、メタンなどを入れるのには、耐圧性の大きな継ぎ目なしの厚い容器を用いる。通常7立方メートル(1気圧換算気体容積)、高さ1.5メートルぐらいの大形、1.5立方メートル(1気圧換算気体容積)、高さ1メートルぐらいの小形などがある。ボンベは入れるガスの種類によって外部の塗装の色を定めてあり、間違いによる危険を防止している()。ボンベに入った気体を使うのには、減圧弁を取り付けて圧を下げて取り出す。減圧弁にも低圧用と高圧用があり、いずれによるにしても放出ガスの圧と流量が微調整できるようになっている。ボンベは直射日光、火や振動を避け、また転倒防止の架台や鎖で固定して使う。
