OREANDA-NEWS. September 14, 2012. EagleBurgmann, a Freudenberg Group company, is supplying special seals for most of the pumping stations on the ESPO (East Siberia Pacific Ocean) pipeline. The involvement of EagleBurgmann is an example of Freudenberg's concerted expansion in the oil and gas production field.

ESPO (East Siberia Pacific Ocean) is a mammoth pipeline project. The pipeline, with a length of almost 5,000 kilometers, is being built in the East of Russia by Russian state company TransNeft. When it is completed, in 2016, the ESPO pipeline will supply oil from Siberia to China, Japan and Korea. With the development and infrastructure construction of China, demand on oil and gas is growing. The ESPO pipeline will greatly help to mitigate the increasing energy demand.

The pipeline, with a total length of almost 5,000 kilometers, is to be equipped with 43 pumping stations, each with four pumps. When completed, the average distance between pumping stations will be about 150 kilometers. Currently, seven stations have already been installed on ESPO-I, corresponding to an average distance between stations of about 400 kilometers. Five further pumping stations are now being built as part of the expansion of the first part of the project and EagleBurgmann was recently awarded a contract for three further pumping stations on a section of ESPO-I.

"We are already in demand as a partner because of our experience and technical expertise. However, there is still considerable potential for expansion of our activities," said Dr. Mohsen Sohi, Speaker of the Freudenberg Management Board. "We have identified oil & gas as a high priority strategic segment which means we will continue to invest and build Freudenberg's businesses in this area."

The extreme climatic and geographic conditions in Siberia mean that the installed equipment faces considerable challenges. The pipeline, with a diameter of 1200 millimeters, crosses earthquake prone areas and significant elevations. This means that the components used must meet high requirements in terms of quality, sturdiness, availability and durability. The pumping stations themselves are often located in difficult terrain and are almost inaccessible. Logistic structures that minimize upkeep, maintenance and repair work are, therefore, essential. Such requirements can only be met by low-maintenance, low-repair components of the type supplied by EagleBurgmann.

Technical competence in the oil and gas industry and extensive experience in the sealing of crude oil pumps under difficult conditions already qualified EagleBurgmann to supply high-pressure seals and sealing systems for ESPO-I. Under the follow-up order for the completion of ESPO-II and the expansion of ESPO-I, the Russian pipeline operator TransNeft is to receive seals from the tried and tested SH and HR series designed for use in pumping stations and pumps.

To meet the special requirements of this project, seals have been specially designed in close cooperation between design engineers, pump manufacturers and the system operator. Tests showed that the seal solutions of EagleBurgmann achieved friction and leakage values significantly lower than the limits that had been specified. "Our customers attended the tests to obtain a first-hand impression of our expertise and the quality of our products," explains Franz Schafer, Sales Manager with EagleBurgmann.
