Tube Bundle and Heat Exchanger Cleaning

EPIS has an extensive inventory of specialist water jetting accessories including remotely operated automated systems for the effective and efficient cleaning of tube bundle and heat exchangers.

Maintaining the Efficiency of Tube Bundles and Heat Exchangers

Tube Bundles and Heat exchangers can, over time, become badly scaled dramatically reducing their efficiency.
On a periodic basis this necessitates inspection using the Internal Rotary Inspection System (IRIS) technique, and to allow this the internal tubes of the bundles and heat exchangers have to be cleaned to a very high standard. The IRIS ultrasonic application is used for the inspection of a wide range of materials, including ferrous, nonferrous, and nonmetallic tubing.
This technique allows detection and sizing of wall loss as the result of corrosion, erosion, wear, pitting, cracking, and baffle cuts.

In hazardous environments, de-scaling of both vertical and horizontal tube bundles and exchangers can be undertaken either withdrawn or in situ.
Cleaning operations are on the critical path of many plant turnarounds and our tube bundle and heat exchanger cleaning solutions can effectively remove cleaning from the critical path and offer the minimum amount of downtime.

Technology leads the way when it comes to solving the problem of safely and efficiently carrying out the cleaning of vessels and confined space entry.

Cleaning Managed Remotely or by Human Intervention

Because of the hazardous nature of confined space entry, we’ve developed a range of technologies and methods to safely clean tanks and vessels whether remotely or by human intervention. Many industries, including the oil and gas sector, have an ongoing need for safe cleaning of tanks and vessels. When muds, brines, sludges, sand, scale, waxes, sediment and other such deposits need removal, it’s often the case that human intervention is still necessary; our trained operatives have access to the most technologically advanced equipment available to do the job.

Highly Trained Operatives and Proven Safety Procedures

EPIS’s specially trained teams utilize proven procedures to manage the risks associated with tank cleaning and confined space entry for industries both onshore and offshore. Combined with EPIS’s Safe System of Work, this ensures all projects are safely and successfully completed.

Investing in Safety

EPIS has invested heavily in breathing apparatus and equipment to ensure an absolute ‘fail safe’ operational methodology. The integrity of the primary air supply is constantly monitored by the standby man via the purification unit and/or breathing apparatus trolley. In the unlikely event that both of these systems failed the entrant is also equipped with an Escape set to ensure safe exit from the situation. Safety and quality have top priority in everything we do.

Specialist Confined Space Entry Equipment

An integrated range of specialist equipment has been assembled to maximize efficiency and minimize risk. EPIS uses the latest technology in gas monitors, including portable multi-gas meters to monitor and display up to four gases simultaneously. Typically the carbon dioxide (CO2) and hydrogen sulphide (H2S) toxic sensors are used, but these can be changed in the event that a specific risk assessment identifies the potential of an alternative toxic hazard. Added safety features in this system include ultra-bright alarm lights and a powerful audible alarm, which coupled with a periodic green flash and bleep provide users with the confidence that monitoring is always in operation and alarms are never missed. In the case of noisy environments vibrating alarms are used.

Our air purification units are used to treat compressed air and bring it up to breathing air quality. In operation, an air purity analyzer is deployed to verify that air quality is kept within specification
