PIPELINE PIGS

Pipeline 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 doing the pipeline hydrostatic test and after de-watering
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 place of joints. 
5. To discharge ash, remove paraffin regularly or irregularly, 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 anti-corrosive coating.

• Medium Temperature: -40℃ ~ 90℃
• Eblow Curve Radius: R≥1.5D(When pipeline nominal diameter≥150)
• Elbow Curve Radius : R≥2.5D(When pipeline nominal diameter≤100)
• Equal-diameter T-junction of piping should have spherical grate.
• Pipeline’s deformation rate is lower than 10%.
• The main pipeline should use ball valve.
• Metal or non-metal pipeline that which can take the pressure after cleaning.
• Putting right directional cover in the flexible compensation parts.
