Mechanical Maintenance Division

Essem has brought in new technology in the country to reduce the downtime in the plants like, Hydraulic Tube Bundle Extractor, Powerlance along with High Pressure Hydrojetting Systems, which are some of the tools, which have enhanced the safety operation in the process industry and reduced the downtime. Essem has contracts with all the plants of Reliance Industries Ltd, Oil & Gas industries, Steel Plants in the country and also overseas.

In the Downstream sector, ESSEM provides tools to the Refineries, Petrochemical, Power plants and other process industries to clean the static equipment, like Heat Exchanger Tube Bundles by providing special tools and also clean them economically and expeditiously.

ESSEM also manufactures various cleaning systems to meet the specific needs of the customers in Process Industry and Steel Industries. The systems are modified to meet the requirements of our clients.

ESSEM introduced and sold Hydraulic Tube Bundle Extractors to Indian Oil Corporation Ltd. (Mathura), Ceylon Petroleum Corporation, Sri Lanka, Reliance Industries Ltd. Jamnagar, Bharat Petroleum CorporationLtd. Mumbai, Essar Oil and Other companies.

Essem has designed specialized equipments and has assembled and manufactured more than 18 systems for the process industry. 


MULTI LANCE POWER CLEANING SYSTEM (MPC)

Heater – Alumina Plant – MPC


Effective cleaning of condenser tubes in power plants has been successfully demonstrated to be carried out when we use up to 1,000 bar pressure using our MPC system. In Alumina Digestion process the pressure requirement may go up to 2,000 bar pressure and a rigid lance MPC is used in such cases. Essem has developed a MPC system for automated hydrojetting cleaning at high pressure range of 100-2000 Bar.

Using the Remote Controlled MPC, we are able to clean tubes at high pressure and flow to effectively clean the inside of the condenser tubes and other heat exchanger tubes without using any chemicals. This saves tremendous time taken for setting up chemical circulation apparatus as well as there is no treatment required for the waste water. This saves time, gives higher cleaning quality and reduces environmental compliance requirement at the plant.

APPLICATION: For cleaning Condensers/Evaporators/Heater Tubes in Power Plants; Alumina Refineries; Chemical & Oil & Gas Industry. For cleaning FinFan exchangers in plants.

Gun Indexer Cleaning OD

Multilance Cleaning System (MLS): for cleaning ID by MLS and OD by GIS (Gun Indexing System) of the a tube bundle simultaneously for very hard scale deposits in Oil & Gas Refineries/Petro chemical Plants giving more than 90%+ heat transfer efficiency. The tube bundle is rotated on heavy rollers for quick turnaround during cleaning operations. All operations are controlled remotely.

APPLICATION: In Refineries, Petrochemical Plants and other process plants for cleaning of tubes and bundle shell simultaneously.
mpliance requirement at the plant.


APPLICATION: For cleaning Condensers/Evaporators/Heater Tubes in Power Plants; Alumina Refineries; Chemical & Oil & Gas Industry. For cleaning FinFan exchangers in plants.


AIR PRE HEATER CLEANING

Cleaning Operation – Offline

Indian coal contains high Ash content & some imported coal comes with higher Sulphur content. This leads to accumulation of ash deposits between elements of APH Baskets and in Tubular APH, causing thermal inefficiency & increasing Coal consumption. Essem has developed a cleaning method to wherein the basket elements are cleaned up to 1,000 Bar for hard deposits. We have cleaned more than 6,000 Baskets in 4,000 MW plant and given them excellent savings as improved Heat Transfer.

Cleaning Operation – In Situ


In Case the deposits are not hard then all the baskets can be cleaned In Situation saving precious time to take them out & putting them back.
APPLICATION: In Power Plants for Air Pre Heaters


PIPE LINE CLEANING: ROTO MOLE/RHD DEVICE
Rot Mole/Rotating Hose Device cleaning system is a revolutionary internal pipe cleaning system with specifically designed cleaning nozzles. Device rotates the specially designed hoses against the pipe wall as it passes through the pipe for cleaning.

APPLICATION: All process plants having tanks, including large diameter tanks.


TUBE BUNDLE EXTRACTOR

image-23945-m_12.w640.PNG

To extract, clean and insert the Heat Exchanger Tube Bundles may be simple, but is a complex operation and requiring technical skill to manipulate the complete operation. Extraction and Insertion of Tube Bundle at ground level and heights in Refineries process plants requires extra skills. Instead of using just a crane or hydra for extraction, Essem recommends using a Bundle Puller to complete the work in the shortest time possible.

APPLICATION: In Oil & Gas & Petrochemical plants
