Cylinder

Cylinder（ Germany bombe) With, vapor and liquid is possibleContainerSo it is. Depending upon purpose,Portable type high pressure gas vessel、High pressure container for equipmentAnd so on with being called, it is distinguished. Inside is high pressure, steel and the like. As for the hole pickup of contents ones it responded to purposeValveIs installed. There is many a thing where direction of installation is decided.

Type

• Connection it is not the container

compression, the cylinder which stores the gas or the liquid which is liquefied. In order to withstand the high internal pressure, it is made with the manganese steel and the chrome molybdenum steel etc. by fairing just. As for small-sized ones aluminum make. Medium-sized (contents quantity 40? 47 liters) as for thing 40? It becomes the weight about of 60kg. In order to withstand the high internal pressure, as for the external form in general with body of revolution, things such as capsule type or shell type is many. As for main shell filler for industry, nitrogen、 oxygen、 argon、 hydrogen、 helium、 air and liquefactionCarbon dioxide.

• Welding container

It liquefies the cylinder which stores the gas which mainly. Form has designated capsule type as keynote. The material mainly with the steel sheet, welds the zenith section and the basis section which in the top and bottom of the steel sheet which is wound in tube shape are faired in hemispherical condition or plate condition. In addition, raising, among those which you use, there is many a thing where the protective part in order in the basis section to protect the valve in the pedestal and top of skirt condition is installed. As for main shell filler, liquefied petroleum gas（LPG) Liquefaction butane and melting acetylene and liquefaction ammonia.

• Clean cylinder

semiconductor is handled, insideGrindingAs administers processing, maintained the purity of contents ones the cylinder which is designed.

• Air cylinder

AtomizerConnecting paint and the like is spread, fills up the air.

• Cassette cylinder

fuel butane. The cassette cylinder is designated as fuel sourceCookstoveIt calls the cassette cookstove.

Use

• For industry (for product enclosure, for drying, for support burning and the one for air shutoff and the like)
• oxygen scarcity place, compressed air open-circuit self-contained breathing apparatus for diving operation, box respirator
• Medical application ( oxygen inhalation、 anesthesia)
• fuel
• The power source which uses the pressure of the gas (the atomizer, fire extinguisher and the beer server) quality retention of object ones

Distinction of contents ones with color

With the cylinder for the vapor, paint color of the substance is decided by contents ones. (High pressure gas preservation method)

• carbon dioxide (carbon dioxide)... green color
• oxygen… black color
• chlorine…YellowColor
• hydrogen… red color
• ammonia… white color
• acetylene…Brown
• Other types...Murine color

In addition, presentlyLiquefied petroleum gasIt does not depend on this regulation.

Contents onesDeleterious substance、PoisonWhen is, furthermore color of the letter which is stated in the cylinder is decided.

Valve of portable type high pressure gas vessel

As for the valve which is installed in the cylinder, system differs the contents ones (gas kind) depending upon, but for industry (it includes medical application) with, oxygen, nitrogen, argon and carbon dioxide, in case of hydrogen and helium, almost it has become similar type. However, there are some which differ to the style of the clasp depending upon the store (the G system which cuts the outside screw in the clasp and the F system which cuts the inside screw). In addition, the opposite screw is cut only hydrogen and helium. We do not cut the screw in the clasp of the valve of the acetylene cylinder and the gasket is attached, (シャコ ten thousand having been attached on splicing fitting side, it has reached the point where it tightens).

Processing after the using

• As for high pressure gas vessel inside air invades, before consuming completely, there is times when it finishes using when the internal pressure is left it is desirable. As for many of the portable type high pressure gas vessel of single unit type because the proprietary belongs to the gas store, as for the cylinder which the user has not bought after the using, it means with to return to the store. Because as for the high pressure gas vessel, periodic inspection is required, filling up of the gas is not possible to the cylinder which passes the time limit (it can identify with the inspection hallmark).
• Cassette cylinder and the likeCombustibilityWhen contents ones are consumed completely, boring the hole through the cylinder at the place where it does not have the fire, after pulling out the gas inside, it abolishes the disposable cylinder of contents ones. The case of disposal (mainlyRubbish collection car) In the gas which remains insideIgnition、 explosion is done often has happened.
