What pressure should be in a propane tank?

OKP 14 1200

By Decree of the State Committee of Standards of the Council of Ministers of the USSR of December 19, 1973 N 2717, the introduction date was set from 01/01/75.

By Decree of the USSR State Standard dated August 14, 1991 N 1352, the validity period was lifted.

This standard applies to cylinders made of carbon and alloy steel, small volume - up to 12 liters and medium volume - from 20 to 50 liters with a working pressure of up to 19.6 MPa (200 kgf/cm2), made of seamless pipes and intended for storage and transportation of compressed, liquefied and dissolved gases at temperatures from minus 50 to plus 60°C.

The standard complies with the CMEA standardization recommendation PC 2496-70.

High temperature lamps

• There are devices where MAPP gas is used instead of a propane-butane mixture. The flame temperature in these devices is 2200−2400°C. The main energy is concentrated in a cone, which is quite stable and has a pronounced boundary.
• Such products are used for heating, bending and forging massive parts and high-carbon steels. High temperature allows for better tempering and hardening of metal.
• As for welding and soldering, MAPP gas devices do an excellent job with stainless steel, and even thin parts do not overheat. Another advantage of MAPP is its low boiling point, which allows it to be used at temperatures of -20°C even in products without a heating circuit.

Connection

All issues related to resource consumption, for example, how much gas is in a 50 liter cylinder (m3), must be resolved in advance - before connecting. Since the procedure for connecting to the equipment is extremely important from the point of view of subsequent safety during operation, the following series of requirements are taken into account during installation:

1. Threaded connections and other joints must be protected from the slightest leaks to avoid the formation of explosive gas-air mixtures.
2. If the cylinder is located inside a heated room, its overheating is unacceptable in order to avoid an increase in internal pressure above the permissible norm.
3. Transporting containers to the installation site must avoid impact and friction on their body.
4. Elements connecting to the equipment (hoses, adapters, gearboxes) must not be damaged, cracked, dirty, or rusty.

4. TEST METHODS

4.1. Pneumatic and hydraulic pressure tests are carried out in accordance with the “Rules for the design and safe operation of pressure vessels.” Test duration is at least 1 minute. Pneumatic tests of cylinders intended for filling with gases, the penetrating ability of which is higher than that of air, must be carried out in accordance with regulatory and technical documentation. (Changed edition, Amendment No. 4).

4.2; 4.3. (Excluded, Amendment No. 4).

4.4. Cylinders equipped with a chlorine valve are tested with a pneumatic pressure equal to 2.94 (30 kgf/cm2).

4.5. Tensile test according to GOST 10006-80. The test speed up to the yield point and during its passage is no more than 10 mm/min, beyond the yield point is no more than 40 mm/min. It is allowed to control the mechanical properties of carbon steel cylinders using a non-destructive method according to the regulatory and technical documentation. In controversial cases, tests are carried out in accordance with GOST 10006-80.

4.6. Impact bending test - according to GOST 9454-78 on longitudinal samples of type 3.

4.7. If the test results do not comply with the requirements of this standard, tests are carried out on twice the number of samples. If the results of repeated tests are unsatisfactory, the entire batch of cylinders is sent a second time for heat treatment. No more than two repeated heat treatments are allowed. Additional tempering is not considered repeated heat treatment. (Changed edition, Amendment No. 4).

4.8. The volume of the cylinder must be controlled by limiting templates along the length; in this case, the volume of the cylinder should not be lower than the nominal one. The volume of two cylinders from a batch is checked by filling with water and determining the volume or mass of water.

Note. From 01/01/89, determination of the volume of all medium-volume cylinders is introduced. (Changed edition, Amendment No. 1, 2).

Connecting gas cylinders

Most gas cylinders are used to operate kitchen stoves. They must be connected to consumer devices through a reducer. The gas pressure in the cylinder is constantly changing - it depends on the ambient temperature. It is in the range of 4-6 atmospheres. When using a reducer, it is possible to increase or decrease the pressure to the optimal value of the stove.

First, a hose is connected to the reducer, and then a plate is connected to it. The place where the connection will be made is secured with clamps. Then be sure to check the tightness of the fixation with soap foam. If bubbles form, the connection can be considered leaking.

The leak is eliminated by further tightening the nut at the place where the fitting and gearbox are fixed. If a leak is detected in the hose area, tighten the clamps. Once the adjustment is complete, perform another soap suds test to make sure there is no leakage. This check is always carried out when a gas cylinder is connected.

As you can see, propane cylinders are in great demand in various industries. Before choosing certain products, it is worth understanding their characteristics and operating features.

You can also calculate the approximate cost of delivery using TK calculators: *You can determine the volume of cargo using the following formula: D (m) x W (m) x H (m),

where G is the depth, W is the width, H is the height of the load in meters.

G= 320 cm; W=450 cm; H=540 cm.

then V = 0.32 m x 0.45 m x 0.54 m = 0.08 m 3

This means that the volume of our cargo will be 0.08 m3
