Gas sampling tool
Structure of high negative pressure gas sampler b />
This sampler is composed of air inlet joint, air outlet joint, rubber stopper valve, tie rod, piston cylinder, sealing ring and other components
Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the early stages of ancient plants accumulating into coal. In a high-temperature and high-pressure environment, while coal is being formed, gas continues to be generated due to physical and chemical effects.
Gas is a colorless and odorless gas, but sometimes you can smell an aroma similar to apples. This is due to the aromatic hydrocarbon gases gushing out at the same time as the gas
Precautions when using high negative pressure gas samplers Matters
Before use, check whether the rubber stopper valve is sealed. If it is damaged and leaking, it should be replaced in time.
The gas concentration is measured from the latex on the core valve. The tube should be approximately the same length as the copper core.
The piston and cylinder should be regularly coated with Vaseline oil to prevent rust.
The last round of price adjustment window
On March 1, domestic oil prices were stranded because the price adjustment range was within yuan/ton. OPEC's unexpected announcement at the end of the month that it would limit production helped boost oil prices. In this pricing cycle, international oil prices rose sharply during the National Day. Refined oil prices showed a relatively large increase on the first working day. Later, the international oil prices returned to a volatile trend under the influence of excess supply and the rise of the US dollar. However, the average international oil price during this cycle Keep going up.
