Welcome to Petrosystem Supply and Service


From many years PETROSYSTEM SUPPLY & SERVICE has been a leading company in the supply of equipment for the maintenance, cleaning and start-up of oil, gas and water pipelines with our unidirectional and bidirectional pig, poly foam pig, spherical pig, gas air bag and gas seal stopper. We also produce: an intrusive pig signaler, whose non-use of dynamic seals design, guarantees a high quality, low cost, low maintenance product; non-intrusive pig signalers (magnetic and ultrasonic); rapid opening closures (bandlock type); vertical, horizontal and oblique launcher and receiver pig, and sphere trap (that can also be equipped with release fingers for the automatic multiple launch of pigs and spheres).

These flowmeters are precise, reliable, rugged and built to international standards. Sizes range from 5 to 500 mm with flanged end connections and 5 to 50 mm with threaded end connections. All flowmeters are individually calibrated In-house on Certified Calibration Laboratory


Product ID: INS-07-01-04

This is the most basic type of Desuperheater, consisting of a fixed area nozzle arranged to face downstream at or near the Desuperheating pipe. The Mechanical Spray Desuperheater relies on the pressure differential available across the nozzle to achieve the conditions for rapid absorption of the water into the steam.

Multidiameter Pig    

Product ID: PE-01-01-03

The ability to pig Dual and Multidiameter pipelines offers the operator huge potential savings on piping costs and enables a growing number of offshore marginal fields to be exploided. This pig is both cost effective and yet highly efficient for pre-commissioning…..

Non Intrusive Magnetic Pig Signallers

Product ID: PE-02-02-01

The Non-Intrusive Pig Signaller makes pig detection incredibly easy. Easy to install and easy to read – the Remote indication System lets you see passage LEDs up to 100 meters away. The Magnetic Non-Intrusive Pig Signaller is completely nonintrusive and easily bands to the outside of pipelines from 2” to 60”. Since the Magnetic Non-Intrusive Pig Signaller is non-intrusive corrosion problems are avoided.…

Moisture Oil Monitor

Product ID: INS-06-01-03

Water contamination in oil based fluids can cause numerous problems such as loss of revenue, additive depletion, oil oxidation, corrosion, reduced lubricating film thickness, accelerated component wear rates, microbiological growth, reduction of dielectric strength and loss of power as an example . These problems can be prevented by online monitoring , so that problems can be averted in time.

Butterfly Control Valve

Product ID: INS-07-01-02

These Control Valves have less resistance to flow path and are most suitable for handling higher flow rates. These valves are most economical compared to other valve types and can be used for both tight shut off and moderate control duty applications.
Sizes from 2” To 72”

Separation and Batching Pig        

Product ID: PE-01-01-04

Batching is primarily used on multi-product lines which transport different products in the same line and the same time. The problem which occurs is ‘interface mixing’ where the product at the end of one batch mixes with the product at the head of the next. 

Traps for multiple launches

Product ID: PE-03-01-03

These units are designed to allow the sequential launching of pigs and spheres. In conjunction with release fingers and/or coordinated valve operation the launch process can be controlled remotely enabling traps to be installed on unmanned platforms and facilities.
