Professor  We are at the CIRCOR Energy office, you can ask all the ques-tions you need for your future research. 
Student  What is your company in general? 
Manager  CIRCOR Energy owns and operates a range of diversified, his-
torically significant brands that supply thousands of product and 
service solutions to companies around the world every day. 
Student  Is CIRCOR Energy competent in pipeline engineering? 
Manager Pipeline Engineering is CIRCOR Energy brand and a world leader in the design, testing and manufacture of pipeline pigging (очистка полости трубопровода) and flow assurance prod-
ucts, engineering, pipeline cleaning services and project man-
agement. We provide precision solutions for customers' unique 
requirements in the Oil, Gas, Process and Renewables industries, 
where a strong reputation has been built for quality and expertise, 
providing project specific innovative product and service solu-
tions. Pipeline Engineering supplies a full range of pipeline pig-
ging tools, pig launchers (пусковой ерш) and pig receivers, 
quick opening closures (замыкание, закрытие) and pig signal-
ers. With extensive experience and knowledge of polyurethane 
(полиуретан) technology, we also design and produce client-
specific polyurethane products. 
Student   What are your compressor stations? 
Manager A compressor station is a facility which provides the motive power (движущая сила) for the transportation of natural gas 
from one location to another.  Natural gas, while being transport-
ed through a gas pipeline, needs to be constantly pressurized at 
certain distance intervals (usually compressor stations are located 
40 to 100 miles apart along the pipeline, but are sometimes even 
farther apart). The gas enters the compressor station with low 
pressure and velocity, looking for an energy source to move it 
further down the pipeline.  Once past the inlet valve, such as one 
of CIRCOR Energy’s three-piece Series P3 ball valves (шаро-
вой клапан), the gas enters the compressor, which is driven by 
special, high-horsepower turbines, electric engines.  The com-
pressor raises the internal pressure of the pipeline, which is then 
used to increase the flow rate of the natural gas inside the pipe.  
Student  What about gas gathering system? 
Manager  Gas gathering systems collect wet natural gas from the wellheads and transport it to gas processing plants.  Gathering systems can be very simple, short-distance flow control piping systems for the out-put of just a few wells, or complex systems requiring thousands of miles of piping and valves to control the pressure and flow of more than 100 gas wells. CIRCOR Energy has extensive gas gathering system experience, and provides a comprehensive portfolio of ex-pertly engineered valves and pipeline product and service solutions, for moderate to severe environments – from ball, check (обратный 
клапан), needle (игольчатый вентиль) and relief valves (предо-
хранительный клапан) to pig launchers, receivers and signalers, 
laydown heads, quick opening closures and much more. 
Student  And what about petroleum transmission lines? 
Manager  Oil and gas transmission lines consist of all interstate and intra-state natural gas, crude oil, and refined products pipelines. CIRCOR Energy has decades of experience providing valve and pipeline product and service solutions for oil and gas transmis-sion applications, from ball to safety relief valves, to pig launch-ers, receivers and signalers, laydown heads, quick opening clo-sures and a full range of engineering, design, cleaning and man-agement services. As a global manufacturer of highly engineered products, we are committed to continuously developing precision technologies that improve our customers' ability to control the flow of the world's natural resources, and that overcome the in-dustry’s most demanding challenges. 
Student  How is liquid level controlled? 
Manager  Liquid level control is a critical component in the energy value chain, and CIRCOR Energy has decades of experience providing products and services for this application, from ball valves to sight glasses (смотровое стекло) and gauge valves. As a global 
manufacturer of highly engineered products, we are committed to 
continuously developing precision technologies that improve our 
customers' ability to control the flow of the world's natural re-
sources, and that overcome the industry’s most demanding chal-
lenges. 
Student  Why are offshore wind farms increasing in popularity? 
Manager  Offshore wind farms are increasing in popularity as the world looks to other sources of energy than fossil fuels. And as this strategic approach has taken hold (овладеть), CIRCOR Energy 
is at the forefront (на пороге) of providing pipeline products 
and services that enable our customers to move the industry for-
ward, from cable centralizers (центратор), J-tube seals and 
subsea cable protection systems to custom engineering. 
Student  Oil sands are loose sands (рыхлые пески) or partially consoli-
dated sandstones (затвердевший песчаник) containing natural-
ly occurring mixtures of sand, clay, and water. Oil produced 
from bitumen sands is often referred to as unconventional oil. 
How does your company solve the problem? 
Manager  CIRCOR Energy has decades of experience providing products and services for oil sands applications, from a comprehensive portfolio of ball valves to check valves. 
Student  What is a blowdown (продув)? Could you tell us about it, 
please? 
Manager  Blowdown is the intentional relieving (высвобождение) or 
venting (ослаблять) of pressure off of a piping system or the 
equipment in it.  Boilers, HRSG’s, and other petrochemical and 
power equipment need either continuous or periodic blowdowns 
to remove impurities and corrosion scale from their interior sur-
faces. Blowdown valves must function within a control system, 
which normally controls the timing of continuous or automated 
blowdown events.  Other blowdown valves are manually con-
trolled, and must remain closed and leak-free until the refinery 
experiences a turnaround or the power plant conducts its out-
age. Blowdown service is typically demanding, and the valve 
must stand up to high temperature, a variety of corrosive/erosive 
liquids, and debris. CIRCOR Energy’s portfolio of valves can do 
all that and more. 
Student  Regular cleaning of operational pigs is essential to ensure that they continue to provide effective pipeline cleaning, isn’t it? More information, please. 
Manager  Pipeline Engineering provides 'deep cleaning' of dirty or contam-inated pipeline pigs, using our specialist pigging tool cleaning booths (помещение) at our Service Centers. Clients benefit from 
a very quick turnaround of 'dirty' pigs which means little or no 
impact on pipeline pigging operations. Pipeline pig cleaning also 
helps identify parts that need replacing or repairing and we can 
recommend and carry out the required pigging tool refurbish-
ment (ремонт) for clients. 
Student  And what about pigging tool refurbishment? 
Manager Pipeline Engineering provides pipeline pigging tool refurbishment and repair services; this includes pigging tool inspection and when required, the replacement of worn or damaged parts on pipeline pigs to extend their working life. The components we refurbish or re-place as part of this service are the discs, cups, blades, brushes and attachments such as magnets. We also refurbish entire pipeline pig bodies. Pigs sent to Pipeline Engineering for refurbishment are as-sessed and a full report on their condition is given to the client. All of our cups and discs used when we refurbish pigging tools have a wear line (линия изнашивания) which shows when this part will 
require replacing in the future. Stocks of regularly replaced compo-
nents are available to enable a quick turnaround. Pipeline Engineer-
ing can also refurbish pigging tools from other vendor (торговый) 
companies. Through inspection of the pigging tools, Pipeline Engi-
neering is also able to assess whether there are problems in the pipe-
line causing excessive wear or damage to the pipeline pigs and pro-
vide relevant advice. 
Student  Thank you!
