FOLLOW INSTRUCTIONS FOR POSITIONING OF WHEELS |
Short packers have a replaceable double-layer rubber sleeve mounted on a PPH tube. All other parts installed in a packer are made of corrosion resistant materials.
On each side of the packer three wheels are attached at an angle of 120° to prevent tipping over while transported along the pipeline.
The effective packer length is 600 mm therefore they are suitable for repair of pipeline joints or repair of shorter pipeline sections along with insertion of stainless steel shells. |

How to calculate the contact area of the packer
Short packers
Size
Ln = Lg - (PI * (D - (d - 25))/4) - 80 |
|
Legend
Ln ... contact length (mm)
Lg ... packer rubber body length (sleeve) (mm)
D ... pipeline diameter, for which contact
length is calculated (mm)
d ... deflated packer diameter (mm) |
