What are the specifications and sizes of liquefied gas tanks?

Abstract: In many places in rural areas and cities, there are still many cases of using liquefied gas. When choosing a liquefied gas tank, you need to know the specifications and sizes. What are the specifications and sizes of liquefied gas tanks? At present, the common sizes of liquefied gas tanks are 5 kg, 15 kg and 50 kg, which can be selected according to the use situation. The following is a detailed introduction to the knowledge of purchasing liquefied gas tanks. 1. What are the specifications and sizes of liquefied gas tanks?

The general dimensions of ordinary household liquefied gas tanks are: perimeter1.04m, upright outside 0.33m, and height 0.69m. At present, there are three specifications of commonly used domestic liquefied gas tanks: 5 kg, 15 kg, 50 kg, and the commonly used household liquefied gas tanks are 15 kg. You can use a bigger one for a hotel, usually 50 kilograms. And the kitchen of a small restaurant can use 5 Jin.

Second, how to choose a liquefied gas tank

The selection of liquefied gas tanks must be "carefully selected", and it is necessary to look, inspect, measure and weigh.

1, see if there is a manufacturing license.

The state implements a production license system for the manufacture of liquefied petroleum gas cylinders. When purchasing a steel cylinder, consumers should see whether the steel cylinder or shield is marked with the manufacturing license number, the name of the filling gas, the product standard number, the actual weight, the actual volume, the supervision and inspection mark or the inspection steel seal mark, and whether there is a product certificate and quality certificate. According to the regulations, every ex-factory steel cylinder must have a product certificate, and every batch of ex-factory steel cylinders must have a batch of inspection quality certificates.

2. Check the appearance of the bottle

Carefully check whether the coating of the cylinder is uniform, and there shall be no defects such as bubbles, flow marks, cracks and peeling. Whether there are cracks, arc damage and double skin on the bottle body, cracks, air holes, slag inclusion, undercut or irregular mutation on the welding part, and whether there is damage to the bottle valve seat and bottle valve thread. According to the national standard of Liquefied Petroleum Gas Cylinder, the surface of the cylinder should be smooth, and there should be no cracks, double skin, slag inclusion, pits with a depth of more than 0.5 mm, scratches with a depth of more than 0.3 mm and corrosion.

3. Measure the air tightness of the cylinder valve

Dip the bottle into water, tighten the valve, and observe whether the valve port and valve stem are leaking. Block the valve port, slowly open the valve, and observe whether there is air leakage at the valve stem. If there is air leakage, it means that the air tightness of this cylinder is unqualified and it is not suitable for selection.

4, according to the filling quantity

Filling quantity is an important content to ensure the safe use of consumers. SYP- 15 empty bottle weight 17 kg, with an error of 0.5kg；; Filling volume 15 kg, with an error of 0.5 kg. The filling quantity should not be too much or too little. If the actual filling volume is lower than the lower limit of filling volume, the rights and interests of consumers will be damaged; When the actual filling quantity is higher than the upper limit of filling quantity, it will pose a threat to the safety of consumers. Therefore, consumers should not be greedy and cheap, and pick overweight bottles.

In addition, I would like to remind you that in the process of using liquefied gas tanks, don't turn them upside down and lay them flat, and don't bake or heat them with fire, otherwise liquefied gas liquid will enter the pressure regulating valve, causing fire accidents.
