Pipeline Pig Launcher

Description

1. Relevant knowledge of Pipeline Pig Launcher

The Pipeline Pig Launcher is an oil field product that automatically receives wax removal balls. Its design is very reasonable. And it is safe, reliable, compact, and convenient to install. Therefore, it can realize unattended, regular, automatic, and continuous pig collection for many times. The application of this device can reduce the labor intensity of employees. The pigging operation cost can also be saved. So this can improve the economic benefits of the oil field.

A brief introduction to the function of the quick ball receiving device. Pipeline cleaning is one of the contents of cold oil production. The purpose of releasing the pig is to dredge the pipeline. Because it can use the movement of the wax removal ball in the pipeline to remove the wax condensed on the oil pipeline wall to achieve this purpose.

The pigging operation of the pig is very simple. That is to put the pig suitable for this device into the pipeline through this device. The pig moves to the oil gathering station under the action of oil pressure. Then it will scrape off the condensed wax on the pipe wall during this movement. Finally, the operator collects the pig at the oil gathering station or at the end of the pipeline through the quick ball receiver. The repeated operation of this pigging work can effectively achieve the effect of wax removal and pipeline dredging. Therefore, it can effectively ensure the normal oil transportation of the pipeline. So if you have any other questions, please contact our professionals to answer them for you.

1. Structure

The quick ball receiver includes a ball receiver and a vent/blowdown pipeline. There are bypass pipelines, electrical control system, a protection box, and other parts

2. Working principle

The pipeline Pig Launcher is arranged inside the pig receiver of the quick pig receiver. It can accommodate pigs from the pipeline. During normal operation of the unit, the pig receiver will receive the pig from the pipeline. And this process does not affect the normal oil transportation work of the pipeline. When I put the ball in the basket. Then they empty the pig in the ball collecting basket and reload it. At this time, the device enters the state of automatic pig storage again. The oil transportation during taking out and basket loading is performed by the bypass pipeline. The normal operation of the pipeline will not be affected during the whole removal and blue-filling process.
When used in winter, the device has a heating and thermal insulation system. It uses the heating system to heat and insulate the device. The advantage of Pipeline Pig Launcher is that multiple pig balls are automatically collected by the pig receiver. And no personnel is required to be on duty. Therefore, no personnel is required to be present to receive the ball for several consecutive days after one blue cleaning. This greatly reduces the number of times that the operators go to the site to receive the ball. The operating staff can go to the site to clear the blue again within the set time.

2、 Standard operation

1. Preparation before receiving the ball

One person shall operate and work with a certificate. Wear complete labor protection articles
300mm adjustable wrench. “F” type wrench. 1000mm crowbar, cotton yarn, dirty oil bucket. 1 ball receiving barrel

2. Check

First, check whether the grounding line, grounding wire, and thermometer are in good condition.
Second, check whether the pressure gauge is within the calibration period. Also, is the pressure within the normal measurement range
Then, check the connection parts for leakage
Check whether the seal of the ball receiving barrel is well sealed
Finally, confirm whether the process is normal

3. Switching process

Open the bypass valve of the pipeline Pig Launcher. Then close the inlet and outlet valves. Finally, open the vent valve to vent

4. Heating

After confirming that the pressure returns to zero, we start the electric heating device. Stop heating, and cut off the power supply when the temperature in the ball receiver shows 40 ℃ – 50 ℃.

5. Catch the ball

When the pressure is zero, people should stand at the side and remove the positioning lock pin
Open and close the door cover of the ball receiver or the quick flange of the ball receiver
Take out the ball with the ball-receiving tool
At this time, the operator shall check whether the flange sealing ring is intact. Then close the quick flange or the door cover of the ball receiver
Upper the locating pin and close the vent valve

6. Recovery process

Slightly open the outlet valve for a pressure test and confirm that there is no leakage
Open the outlet valve and inlet valve. Close the bypass valve
Confirm that the process and pressure are normal

7. End receiving

Clean the wax removal ball
Check and record the ball throwing and receiving. Arrange the received wax removal balls according to the good group

8. Pack tools

Clean up tools and site

9. Precautions:

Risk identification (beware of electric shock, object strike, oil and gas leakage, poisoning, fire, slipping, and equipment damage)

3. Technical requirements

1. After the pressure of the pressure gauge drops to zero, remove the positioning lock pin;
2. The heater power must be cut off during the blue cleaning operation;
3. Before opening the quick-opening blind plate, it must be ensured that there is no pressure in the pig receiver during the pigging operation. That is, ensure that the blowdown valve and vent valve are open. The inlet and outlet valves of the receiver are closed;
4. The wax removal ball shall be seated according to the number, and the record shall be consistent with the good number;
5. Check whether the sealing ring is intact when installing the ball receiving barrel cover;
6. Timely maintain, update and calibrate pressure instruments. And keep the machine running below 0.6MPa. Prevent vessel overpressure;
7. Timely replace the qualified grounding wire and sheath. And pass the test;
8. It is forbidden to pass through the ball receiving barrel when cleaning the line.
