cleaning pigs

Products overview: As is known to all, when the pig in the pipeline, in the operation of the bottom of skin bowl with pipeline interaction, due to friction heat loss, skin bowl bottom will soften. At the same time, because of the pig itself exists, the pig weight weight in the pipeline in all its weight by running at the bottom of skin bowl, so that is caused due to friction heat loss caused by gravity and skin bowl in DN300 general specification includes skin bowl in the pipeline in the long run can do. If the operation time is too long, cause the axis of the pig is the same with the pipe axis, pigging result is bad. Heavy, because skin bowl bottom badly worn, makes the transmission medium, the leakage recharge will lead to greater operation, the pig can halt, by the pig into "blocked". So QDQ - Z pig, solve the problem, just for long distance pipeline transport work provides new ideas.QDQ - Z supporting wheel pig is normal skin bowl pig of product (patent no. : ZL01212169. X), solved the ordinary pig due to the bottom of the gravity caused by itself would eventually lead to serious wear cannot use leak. Supported by elastic plate wheel rolling wheel, arm and support to the pig and pipeline remain in the same axis running, skin bowl in the operation of wear uniform, maintain good sealing effect and improve the operation, increase skin bowl from the service life of 3-5 times. It is the ideal of the long-distance conveying pipeline pigging products. This product in the oilfield, the use of natural gas pipeline by experts and customers.The ordinary pig is mainly used for the cleaning work, drainage pipe line cleaning and residual impurities. Can be natural gas, gas combudstible gas discharge. Will different liquid medium in pipelines in isolation.The steel brush pig is mainly used for eliminating rust and wax on surface inside the pipe . Through the ability, good rigidity, using effect is obvious.
