Liquefied petroleum gas (LPG) in the chemical field belongs to class A and
A dangerous fire hazard with a very low flash point, easy combustion, large
volume expansion coefficient and explosion risk. So the transportation
operation has always been a relatively high-risk work.
Common petrochemical gas discharge connection is mainly standard flange bolted
connection. Before the operation, all staff must wear safety protective gloves
in strict accordance with the regulations, and check the status of
corresponding tools such as wrenches. In addition, the long-term maintenance
of flange joints should be done regularly. From the early use of rubber
asbestos gasket seals and 45 steel plain bolt combination; To a modified
combination of metal wound gaskets with inner and outer rings and high
strength bolts (35CrMo).
Although the components have been significantly improved in
anti-low-temperature ageing, sealing and bolt strength, the essential
operation process has not been changed, and it is still necessary to use no
less than 5 bolts in accordance with the regulations to complete the operation
in the direction of symmetry and crossing.
In addition to the factors such as the quality of storage tanks and the
failure of safety accessories, human error is still the most difficult to
control in the worksite.
Due to the complicated operation procedures, even as more experienced staff
will inevitably appear the operation of the scene, including the bolt
fastening is not uniform, due to inspection negligence caused by the flange
and seal gasket failure was not found, etc.
To sum up, misoperation, blind command and poor maintenance of equipment in
conveying operations lead to material running, bursting, dropping and leakage
everywhere. The first is to cause frostbite or poisoning accidents to staff, and
the worst is to cause open fire explosion.
Thus, it can be seen that the fault tolerance rate of traditional flange
connection is low. In the process of multi-link operation, there will be the
probability of human error, and the long operation time will also increase
the risk of accident virtually.
Then, as the "zero overflows" Dry Break Coupling of SME Industry, the
problems in the above scenario can be solved once and for all.
The humanized handle design only needs the knob joint to complete the
connection. The operation time of 5 seconds before and after and the special
internal two-way disc mechanism can realize the effective fast opening and
closing and the preferential working condition requirements.
Most importantly, the near-zero overflow effect can effectively protect the
safety of operators, and the high risk of leakage and the complicated
operation process will become a thing of the past.

The "South-to-North Water Diversion" project promoted by the China government in 2012 is a basic project to optimize the allocation of water resources and promote coordinated regional development. It is a strategic project with the largest investment and the most extensive coverage since the founding of China. South-to-North Water Diversion In the fact , the water supply area on the east line of China was densely populated, concentrated in cities, convenient in transportation, and rich in resources. It was an important energy and chemical production base and a major production area for agricultural products such as grain. The potential for economic growth is huge, but the contradiction between water supply and demand has become increasingly prominent. Water shortage has restricted economic and social developmen...
Nowadays, natural gas, which ordinary people usually use for cooking and heating, is also used as vehicle fuel. Compared with diesel, natural gas combustion produces very little pollution and does not produce any smell or smoke. Another advantage is that vehicles that use natural gas as fuel produce three times less noise than those that use diesel, so the vehicle can drive in urban areas without noise pollution. When natural gas is liquefied as fuel, it is commonly referred to as liquefied natural gas (LNG) . Specifically, it is obtained by condensation at -162°C. Compared with the gaseous state, the liquid volume is reduced by about 600 times. In other words, fuel tanks with highly enriched natural gas can provide trucks with a distance of more than 1,000 kilometres . When the vehicle is running, natural gas is injected into the engine in a gaseous state and converted into the power required by the...
Generally, when the inner wall of the pipeline is smooth and the water flow is free to move, if the opened valve is suddenly closed, it will cause the instantaneous impact pressure of the water flow on the valve under the action of inertia, commonly known as the "water hammer phenomenon". This is also the true face of the strange noise at night in the residential area. When the valve is closed, the pressure generated by the pipeline is too high, which can easily cause the water pipe to burst, which is called "positive water hammer"; on the contrary, the pressure generated when the valve is opened is too low, which will cause the pipeline to collapse, which is called "negative water hammer." The common point is that they will all have a strong destructive effect on the pipeline, and the valves and fixtures themselves will not be spared. Another form of water hammer is called "steam water hammer",...
