Liquefied petroleum gas cylinder can be used in the end a few years?
Liquefied petroleum gas cylinders can be used in the end a few years, some say 15 years, some say 12 years, some say 8 years, in the end is what kind of statement is accurate?
YSP12 (formerly YSP15): the useful life of 12 years

YSP118 (former YSP50): the useful life of 11 years
Old standard introduction
We are all familiar with the old standard: the cylinder can be used for 15 years, YSP15 cylinder, for example, the first four years of direct use, the first test of the fourth year, the second test of the eighth year, the third test of twelve years; After the third test, the deadline of 15 years until the date of production of the cylinder is directly expired and it will become a waste bottle and can not be reused.
Some customers also said that the cylinder cylinder steel cylinder has been the third test, it may have been from the production date of fourteen years, then use three years is not seventeen years? Xiaobian want to tell everyone clearly, wrong, fifteen years deadline, directly scrapped, there is no reason.
State Administration of Quality Supervision in 2015 on the life of the cylinder requirements
Official Document: Notice of the General Administration of Quality Supervision, Inspection and Quarantine on Relevant Issues on Safety Supervision of Pressure Gas Cylinders (QCQT  No.675) Section 2: Safety Assessment of Liquefied Petroleum Gas Cylinders.
In accordance with GB5842-2006 "liquefied petroleum gas cylinders" standard manufacturing cylinders, manufacturing units promised design life of 8 years to reach the design life of liquefied petroleum gas cylinders, you can pass the safety assessment of qualified, the longest not to use More than one regular inspection cycle. Safety assessment by the liquefied petroleum gas cylinder inspection qualification inspection agencies in accordance with GB8334 "liquefied petroleum gas cylinders regular inspection and assessment of" national standards. The inspection agency shall be responsible for the conclusion of the assessment and at the same time shall issue a safety assessment report and spray the words "qualified for safety assessment" with a word height of 60 to 80mm on the bottle body.
Liquefied petroleum gas (LPG) cylinders manufactured prior to the implementation of the GB5842-2006 LPG cylinders shall be scrapped with a service life of 15 years based on the date of manufacture of the stamps, and reliable measures shall be taken to eliminate the use functions.
(A) According to the standard production of cylinders, 15 years of service life, according to the normal inspection cycle can be tested.
(B) according to GB5842-2006 (on the cylinder with the production and deadline, and the national standard), the useful life of 8 years, according to the normal inspection cycle can be tested.
(C) to eight years, the cylinder monitoring station should be issued a safety assessment report and the bottle sprayed with the word height of 60 to 80mm "safety assessment of qualified" message, you can re-use a test cycle.
(D) YSP12, YSP35.5 two kinds of specifications for the inspection period of four years, YSP118 specifications for the inspection period of three years, so the final conclusion is: YSP12: 12 years, YSP35.5: 12 years, YSP118: 11 years.
