Liquefied petroleum gas cylinders - According to case studies and experiments show that the main reasons for the explosion of cylinders are the following aspects

1, super-test cycle filling, liquefied petroleum gas cylinder is a seam welded containers, cylinders as a user's small air supply, the use of space is often small and humid, leaving the bottom of the cylinder rusty, wall thickness susceptible to corrosion, the use of During the process, the outer skin often falls off due to the collision, the cylinder is deformed, the cover is loose or even damaged, and the steel bottle will wear naturally throughout the year. Seals inside the angle valve may also cause gas leakage. According to GB8334-2011, liquefied gas cylinders Should be regularly tested, no use of untested cylinders. However, the actual inspection rate of the cylinder is still very low, a large number of undetected cylinders still exist in every corner of society, leaving many major security risks. The company is located in:

2, overloading and over-temperature use, the specification requires liquefied gas in the cylinder filling capacity of not more than 85%, because LPG with temperature expansion and rapid increase in pressure characteristics, if the bottle is full of liquefaction Gas cylinder may be a physical explosion. The company is located in:

3, the material and production process failed, if the manufacturer's material does not meet the design requirements or welding process failed, the cylinder can not withstand the compressive strength, can also cause an explosion. The company is located in:

4, valve, hose failure lead to leakage, cylinder angle valve, valve loss of control or cylinder connection with the cooker Hose leaks lead to concentration in the air reaches a certain percentage, in case of fire or electrical sparks will explode. The company is located in:

5, savage loading and unloading, the cylinder in the process of filling or shipping may appear savage loading and unloading, so that the outer surface of the cylinder by mechanical damage, combined with user carelessness, improper use or collision or a sharp increase in ambient temperature, causing the bottle explosion.
