Water Treatment Pipeline：
The cleaning of the pipeline is to dredge the pipeline, clean up the sludge in the pipeline and keep it unblocked for a long time, so as to prevent waterlogging in the city. Water Treatment Pipeline cleaning has become an important work that Drainage Department should pay more attentions. In the drainage pipeline, a large number of sundries and cement sand at the infrastructure construction site will precipitate and deposit, which will cause pipeline blockage. Without the cleaning of pipelines, it will cause excessive flow of sewage, pollute the environment and bring trouble to people’s life.
The Cleaning of sewage treatment pipe is necessary. The detection of sewage treatment pipe network is a system network. When there is a problem or damage somewhere, it will cause chain reaction and affect the drainage capacity of the whole system. In order to improve the drainage capacity and prolong the service life of the pipeline, it is necessary to establish perfect pipeline inspection and evaluation methods and scientific maintenance means for regular inspection, evaluation, dredging and repair. We also believe that the internal inspection of the pipeline is an important part of this project. It can not only scientifically and intuitively understand the internal conditions of the pipeline, but also provide accurate information for the maintenance of damaged pipelines.
Water treatment pipeline engineers should block the pipe before the cleaning process. According to the actual situation of the pipeline and the water flow intensity in the pipeline, in order to avoid a certain threat to the downstream construction personnel caused by water pressure generated by the upstream ponding after the blocking time is too long, the blocking distance shall be carried out according to the actual situation, and the water inlets of the upstream and intersection wells shall be blocked first. Before blocking, the well cover within the road section to be constructed shall be opened and fences or eye-catching marks shall be placed, detect the gas in the well with gas to ensure that there is no gas before entering the well for plugging.
Oil & Gas Pipeline:
Oil is extracted from the underground to the ground and transported to a large refinery to refine the crude oil into the raw materials and the oil which we need. In the process of transporting crude oil, the main transportation tools are divided into two kinds. One is to transport crude oil by vehicle mounted oil tank truck. In this case, the cost is very high. Generally, crude oil is transported by oil pipeline.
Oil & Gas pipeline engineers should clean the pipe as well. Because the oil pipeline is mainly responsible for the transportation of various crude oil resources and the transportation of resources. If there is leakage in the transportation process, there will be serious safety accidents. Because this type of oil pipeline is usually deeply buried underground and in contact with soil and water for a long time, it is extremely prone to corrosion, which has a serious impact on the safe operation and service life of the pipe network. Therefore, in the process of oil pipeline construction, a series of anti-corrosion and oil pipeline cleaning measures must be taken to ensure the safe operation of the oil pipeline.
Oil pipeline transportation is a long-distance transportation mode of liquid and gas materials. It has the characteristics of large transportation volume, continuous, fast, economical, reliable, stable, less investment, less land occupation and low cost. It can realize automatic control. In addition to being widely used in long-distance transportation of oil and natural gas, it can also transport ore, coal, building materials, chemical industry, grain, etc. There are many impurities in the oil and gas in the crude oil transmission pipeline, including organic matter, carbon dioxide, hydrogen sulfide, bacteria, etc. The existence of these impurities is very easy to cause pipeline scaling. Regular cleaning and maintenance of the oil pipeline will help to prolong the service life of the pipeline, improve the transportation efficiency and reduce energy consumption and leakage.
Usage of Cleaning Pig in Oil & Gas, Water Treatment Industry
1.Pig Launching
1.1 Before launching, make sure that the pressure in the ball barrel is 0, then open the quick opening closure, put the pig ball into the launching barrel and close the quick opening closure
1.2 Open the front control valve of the launching device, slowly open the rear control valve of the launching device, and pay attention to the pig indicator and pressure change
1.3 When the ball indicator shows that the ball has started from the ball cylinder, open the outbound valve
1.4 Record the ball passing time and pressure, and inform the receiver to prepare for receiving the ball
1.5 Close the front and rear control valves of the launching device, open the blowdown valve, remove the pipe cap and open the cleaning valve, connect the compressor air, discharge the pigging residue in the launcher
1.6 Close the blowdown valve and cleaning valve, open the quick opening closure, clean the inside and outside of the launcher, close and lock the quick opening closure, and reset the pig indicator
2.Pig Receiving
2.1 Prepare to receive the pig ball according to the operation of the pig ball
2.2 Slowly open the front and rear control valves of the ball receiving device, slightly close the inlet valve, and pay attention to the pig indicator and pressure change
2.3 When the pig indicator displays the pig has enter the receiver, fully open the inlet valve and close the front and rear control valves of the ball receiving device
2.4 Open the blowdown valve of the ball receiver, remove the pipe cap and open the cleaning valve, connect the compressor air, discharge the residual liquid in the pipe and clean the receiver
2.5 Close the blowdown valve and cleaning valve, then open the quick opening closure and take out the pig
2.6 Clean the inside and outside of the receiver, close and lock the quick opening closure, and reset the pig indicator
