The leader of the Department of Chemical Fertilizers received a report from Pang Gang about the leaking of the PDIA206 pressure guiding pipe. The leader of the fertilizer application department went to the site to investigate: The lead pressure connector of PDIA206 is located on the pipeline between EA202 and EA203, and its process medium is 48.16% of hydrogen. , 47.94% of carbon monoxide, 2.95% of carbon dioxide, 0.10% of hydrogen sulfide. The pressure is 5.39 MPa and the temperature is -13.4 degrees Celsius. The head of the operation department realized that the leak location was a high-risk area for the device and immediately organized the on-duty personnel to close the root shut-off valve of the pressure tube. Since the valve was rusted and the action was not in place, after further inspection, it was found that the PDIA206 pressure pipe ruptured, and the shutoff valve body cover and the valve stem joint had a circular crack. If the valve was forced to close, there was a valve stem rushing out. The risk of a large amount of raw material gas leaks. Due to the flammable, explosive and poisonous nature of the medium, the prefabricated box was decided to use nitrogen-incorporated, external-steam-protected plugging schemes. For the safety of plugging, fire engines and firefighters, and air defense personnel came At the scene to help out.
After Jian'an company's maintenance personnel prepared meticulously and dispatched elite troops, construction quality and safety were strictly controlled. During the construction process, we received strong support from the leaders of the relevant agencies, such as the motor division, safety ring, fire brigade, and gas defense team. Although there was a variety of difficulties in the process of plugging, such as the ignition of raw gas, due to the full preparation Finally, after five hours of battle, the box was successfully welded. A serious accident with parking was avoided.
Jingcheng card water meters include IC(Integrated Circuit) card and RF(Radio Frequency) card are the new measuring instruments employing the microprocessor to realize water collection, processing, display, and reserving.
Jingcheng developed a new mobile radio system especially for remote reading of water meters, Heat Meters and energy meters for heating and cooling.
Our prepaid meters are designed for situations where a wide flow range must be covered. Quick responsiveness, even at low flow rates, combined with power reserves for high flow rates makes this meter model the ideal partner for service connections in water supply.
Constant development guarantees accurate measuring results and the best long-term stability. Constructional details, such as the design of the turbines result in excellent true running characteristics and minimum bearing loads. All movable parts have an optimised specified weight.
Together with the special arrangement of the bearings and the turbine, this guarantees a minimal moment of friction and a long service life.
In use by the million worldwide, our domestic water meters will convince you thanks to their high technical standard and high-quality workmanship. Precise measurement results are achieved, even where the water quality varies or in the most difficult installation situations.
FEATURES:
â—Card Water Meters use pre-paid way to achieve the new management mode
of "purchase first, then use".
â—Show the different level price of the water, one card can be used to several meter.
â—Double reading display: mechanical and electronic reading, the unique
battery protection
