polyurethane wheel supporting cleaning equipment with steel brush

Use

Used for various pipeline put into operation before the pigging, which can eliminate the  stones , sticks and other debris left in the pipeline during construction

Natural gas pipeline cleaning after operation

Exhaust before hydraulic test

Applicable medium

Crude oil , Refined oil , Edible oil, gas , chemical materials,  Liquified natural gas,

Coal water slurry , Sewage, Tap water etc.

Detailed intro

QDQ-Z type wheel-supporting cleaning pigs(patent No.:zl01212169.x) is the substitute of the reguglar pig. The regular cleaning pigs cant solve the problem  of bottom damage cause of itself weight and even leakge to useless. the wheel-supporting cleaning pigs are supported by resilient arm and rolling wheel makes the pig and the pipeline keep in the same axis. the cup even wearing during operation keeps the good sealing effect. meanwhile, Improve the operation distance and the working life of cup improve 3-5times. its the ideal long-distance conveying pipelin pigging products. hence, the wheel-supporting cleaning pigs are very popular in the oil and gas field and get very positive feedback from our customers.

Advantage

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.

Cleaning pig application

1.To be used for sweeping pipeline and cleaning various impurity After finished the pipe construction 

and pre-silicon .

2.To be Used for the exhausting gas before do the pipeline hydrostatic test and dewatering after test. 

3.To check the roundness error before usage and whether the position of live ball valve and pipeline 

diameter are accurate after opening valve.

4.To wipe out the weld flash at the palce of joints

5.To discharge ash, remove paraffin reguarly or irregulary, descaling and do water treatment of the 

used oil and gas pipeline.

6.To be used as the inolator of different fluid medium during one pipeline.

7.To paint the the pipeline wall with anticorrosive coating.

The advantages of the electronic locating equipment of pipeline pigging are strong wear resistant 

property and passing ability, well cleaning efficiency, accurate locatingand tracking, etc. the precision 

can reach to plus or minus 5cm

we adopt the whole sealing structure for the installation of our cleaning pig battery. As the high speed 

in the pigging operation and severe collision,it easily cause the pig transmitter out of power and cant 

work. our whole sealing structure takes Rechargeable lithium batteries and have the clectrucal quantity 

standard to make sure the battery with enough power for supporting the transmitter to work reguarly.

our battery can also avoid the humidity even water into the inner make the battery mouldy or even 

short circuit.
