The Benefits of the Process

Pigging System Include: Minimized (or eliminated) cross-contamination.

Decreased down-time for product changeover.

Recovering of normally wasted product.

Adaptable to your individual application.

Minimization of dedicated lines.

Increased product purity.

Resulting in:

$$$ Increased profits $$$


4/22

The key is in the design of the pig.

Its design minimizes bypass, which equates

to a purer product and less cross-contamination.

Up to 99.96% effective atproduct removal in a single run !


5/22

The Process

Displacement Pig Has 12 Sealing Discs

(The most found on ANY pig).

Is equipped with a

unique nose forretrieval from pipe.

Is capable of spanningfull-branch tees.

Is able to negotiatefull-port valves.

Is flexible enough tonegotiate 1.5-diameter

bends.

Can be manufacturedfrom various compoundsto be compatible withyour product.

Has the ability to be madeto any diameter, lengthand configuration to fityour application.

Typical Application

The following illustrates a typical

process pigging application.

It is an artistic rendering for illustration

and theory conveyance only.

Your application may differ greatly,

but our PDP Pigging System can be

adapted to suit.


7/22

By utilizing 3-way valves,

pigging tees, and standard

valves, we have eliminated

the need for dedicated lines.

Now, one pipe is able to

transport product to

FOUR

different areas of the plant.


8/22

We begin pumping product

to the Packaging Area.

Notice the pig remains in

the pigging station, waiting

to be launched.

Also notice because of the

3-way valve, tees andstandard valves, product is

not flowing to other areas

of the plant.


9/22

Production has now been

halted (closed valve at tank)and the pig has been

launched with air.

(Notice that the PDP spans

full-branch tees.)

A cleaning solution or

solventor even anotherproductcould be used to

propel the pig, depending

on your application.


10/22

The pig has now negotiated

the 3-way valve, ell, and tee,and is approaching the

other pigging station.

Notice the product that

was in the tee, (between thevalve and mainline), has

fallen back into the pipe.

This will be recovered on

the return run.


11/22

The valve to the Packaging

Area has now been closed,and the pig is being sent

back to the other pigging

station, recovering any

product left in the line.

Once received, the system

can be reconfigured for thenext product operation.


12/22

To fully utilize the benefits of the PDP Pig,

specially designed components need to be

considered for incorporation into your system.(click on individual item icon to view details

Pressure Gauges & Recorders

Pressure Gauges relay vital informationto the operator, including monitoring the

pigs process through the line, signaling

any trouble with the system.

Pressure Recorders are equipped with pen

and chart providing permanent records of

pressures during operation. These provehelpful in determining problem areas in the

system.

Pressure Relief Valves & Regulators

Pressure Relief Valves are

essential when propelling

medium is capable of

introducing more pressurethan pipes rating. They are

adjustable for individual

requirements.

Pressure/Flow

Regulators maintain a

constant output of air

regardless of input. Thisallows for constant pig

speed, which aids in the

efficiency of the system.Return to

Pigging Tees and Ells

Pigging Tees are designed to allow

product to pass through, but not

the pig. They aid in non-dedicated

multi-product piping.

Pigging Ells are manufactured with 2% or

less ovality. This is essential to minimize

bypass and cross-contamination.

Three-Way Valves

Offer the ability of

controlling the

direction of the pig

and product amongtwo or more lines.

These greatly

minimize the need for

dedicated piping inmulti-product systems.

Pig Detectors

IntrusiveConsists of a probethat protrudes intothe pipe and is

mechanicallytriggered bypassage of the pig.Units require

internal access tothe line.

Non-intrusiveConsists of a

magnetic sensor

that detects the

passage of a pig

equipped with a

magnet. Units do

not require

internal access to

the line.

Loading Arms & Hoses

Loading arms need to be

able to accommodate

pigging through entirearm.

Hoses and couplings can

be incorporated into the

system as long as theyare able to accommodate

pigging.

Demisters

Demisters serve to collect

the product mist produced

during the return run. Theunit is filtered to collect

residual product, which can

be drained or piped back

into product tank.

The initial cost is minimal compared to:

$avings gained in recovered product

$avings from minimized piping

$avings in change-over downtime

$avings from wasted product

The entire system can be fully automated andoperated by a single person in a control room,thus lowering operating costs even further !

Numerous companies in varying processingindustries have utilized this system and savedmillions of dollars !!

!!! Let us do the same for you !!!
