MD22 - 1451mm - 356mm

MD series, in sizes 14" and smaller, have a through bolt man-

drel design, complete with a pull hook. The pigs can be equipped

with two or four discs to suit the application. Typically the longer

the pig run the more discs you would install.

Sealing discs experiencing wear after traveling one direction,

can reverse direction without compromising their sealing

characteristics. All discs are produced from Apaches special

blend of wear resistant polyurethane.

TheMD bi-directional pigs are designed to be both economi-

cal and efficient for use in medium length pipeline construction

applications such as water displacement, swabbing or line

clearance duties.

Also useful for separation, batching and during the hydrostatic

test stage of construction. Designed to run in either direction, the

operator can both fill the line with water and then displace the

water without removing the pig.

EDX is an economical 6 disc bi-directional pig which offers

an optimum seal and also allows for aggressive cleaning with

wear compensating, spring loaded brushes. The pigs are equipped

with durable guide discs designed to center the sealer discs in

the line, forming a quadruple seal that virtually eliminates product

by-pass.

The EDX series of cleaning pigs are designed for the bi-

directional cleaning of newly constructed lines or for existing

lines where scale and debris are present. It is also an excellent

choice for air or water displacement applications during the

pressure test stage of construction.

MDK16 - 48406mm - 1219mm

Apaches MDK bi-directional pigs are designed for use in

ong-run pipeline construction applications during the hydrostatic

test stage. Designed to travel in either direction, the operator can

fill the line with water and displace the water without removingthe pig. TheMDKmandrels are engineered to easily be adapted

to a cleaning pig by the addition of flat steel wire brushes.

MDK pigs have both an inner mandrel and outer mandrel.

The MDKs dual mandrel is favoured by contractors, as the

nner mandrel withstands the battering inherent during

construction phases, while the outer disc carrying mandrel

remains untouched.

The pigs are equi pped with durable guide discs, one at eachend. They provide a positive centering affect which allow the

four sealing discs in the center to effectively seal during the

displacement period. Apache bumper noses are also included

with MDK pigs. They prevent damage of expensive in-line

auxiliary equipment. Transmitter cavities and handling hooks are

other standard features on the MDK.

- Spring loaded brushes or

blades are available between

the sealing discs.

- Plate magnets can be

mounted to recover any

ferrous debris in the pipeline.
