Designed to shoot Conco TruFit or any other make or model of tube cleaners through tubes from 1/2” to 11/2” O.D. , it increases available water pressure up to 300 PSI necessary for effective cleaning. This unit is equipped with a 10 HP motor and a durable positive displacement two - gun pump.


Tube Cleaners

Each tube cleaner is designed for specific fouling types and sizes for your exact tube dimensions to ensure safe and effective tube cleaning.

Conco has more than a dozen designs engineered for the effective removal of fouling and underlying corrosion. 


Rotary Drilling

Utilizing a water flush and rotary action, Conco HydroDrill Tube Cleaning Systems are the fastest and most effective way to remove difficult deposits from the inside of heat exchanger tubes, chemical reactors, condensers, reboilers and absorbers. The HydroDrill system is designed for maximum cleaning effectiveness with no tube damage. Drill bits are sized to be 0.005” below the minimum tube I.D. They feature long shanks to ensure that the axis of the bit and the axis of the tube are in complete alignment. Furthermore, the bits are designed with carbide tips on the leading edge with rounded corners to ensure no sharp edges directly impact the tube wall. The drill also rides on a thin layer of water for lubricating bearing surfaces between the bit and the tube. HydroDrills have been used repeatedly to clean process fouling on some heat exchangers over 1,000 times – with no tube damage or degradation. HydroDrills are used to remove hard tough deposits including: Coke, Calcium, Sulfur, Bauxite, Alumina, Asphalt, Oxides, Polymers

Protection of tube metal by polymer coatings will prevent oxide formation on your tube wall, extending life and eliminating unplanned maintenance of tube leaks. Coating can be used to protect against aggressive acid and alkaline.

Polymer coatings will reduce the surface tension of even a new tube by factor of 50; this inhibits the ability of fouling to attach to the tube wall, and eliminating cleaning cycles.

Over 70% of total heat transfer resistance for heat exchanger tubing is boundary layer fluid film and fouling. Removal of fouling and reduction of boundary layer drag of the exchanger enhances flow profile of the tube wall for the operational life, increasing heat transfer.

The sleek properties of high performance coatings substantially reduce tube wall friction, or boundary layer drag. Reducing drag can increase flow rates up to 80%, pressure differentials have been reduced by 50%. Without flow degration from corrosion and fouling these values remain constant.

A monitoring pipe with a fitted valve that is affixed to the old pipeline allows the system-specific annular space to be monitored after the renovation work. Natural Gas Core Gas Liquid Gas Mixed Gas. Please get in touch with us for our Chemical Resistance sheet to know more.



Assembly of the pulling head

Before installation, the liner is fitted with a pulling head that is designed for forces of up to 100 kN. A swivel in the pulling connection with the winches prevents the liner from twisting on its way from the start to end pit.


The liner is delivered folded. That way Primus Line® can be installed even in pipes with the same nominal diameter.

Adhesive tape keeps the liner in this U-shape until it is pressurised with about 500 mbar. Subsequently, it assumes its round form.


Assembly of the M-Connector

The M-Connectors by Primus Line consist of a bushing and a core. With the M-Connector, a pull-proof unit out of the liner and connector is established by hydraulically pressing the core into the bushing.

Screwed to a flange on the host pipe a leak-free pull-proof connection is established that forms a closed annulus.

Assembly of the R-Connector

The R-Connectors by Primus Line Consist of a core and a bushing.

With R-Connectors, the core is first fitted into the bushing with an anti-friction agent. The busing has a malleable steel jacket inside that is pushed onto the liner and into an indentation on the core by a two-component resin. The result is a pull-proof unit of liner and connector.

A leak-free pull-proof connection with the host pipe can be established with a flange or welding solution.
