As with most power plant equipment that experiences deterioration from continuous operation, the GE Flex Seal plates can lose their sealing capabilities and flexibility over time. As a result, excessive hot gases are released into the surrounding atmosphere, endangering critical control wiring and equipment. Cold air can also enter the turbine, reducing thermal performance.
The two-ply testable bellows (also referred to as a redundant ply design) can, in majority of cases, provide early warning about bellows failure. Although a representative sample performs in a statistically predictable way, any single expansion joint’s exact fatigue life is unpredictable.
The operation of high pressure pipeline pumps poses great challenges to end users. Strict environmental standards must be met, and the cost effectiveness and availability of the numerous pump stations must be assured. Product leakages must be prevented by all means necessary. As a result, the pump shafts are sealed with dual seals with unpressurized buffer or pressurized barrier systems.
Global Amines is one of the worldwide leading manufacturers of specialty chemicals. The Southeast Bavarian “chemical triangle", near Altötting, Germany is the location of the Gendorf plant. Global Amines produces preliminary, intermediate and finished chemical products here.
The Sannazzaro de' Burgondi refinery is located in northern Italy, approximately 31 miles (50 km) to the south of Milan. It was commissioned in 1963 and belongs to ENI, the crude oil and energy group. Investments in sustainable technical expansions and innovations were made over the years, and the daily processing capacity increased to over 180,000 barrels of crude oil.
The GSO-DN gas lubricated seal, previously only manufactured and sold in Germany, is now available for order in the US.
The CobaSeal is more robust than older seal types, consistently reliable in all operating conditions, and provides cost savings in the form of reduced Nitrogen gas consumption.
The new zero-leakage RPHmdp API 685 refinery pump was developed utilizing high-efficiency magnetic couplings from the proven EagleBurgmann MAK685 series to seal the shaft.
Contamination is the leading cause for dry gas seal failure. As identified in this article, if process gas or inadequately conditioned seal gas is provided to a dry gas seal, it will affect the reliability of the seal.
As part of a Tulsa refinery’s upgrade project, EagleBurgmann Expansion Joint Solutions (Lakeside) was awarded several orders for expansion joints including a large tied universal elbow expansion joint for the Fluid Catalytic Cracking Unit (FCCU).
