Pipeline Components
Pipeline Components
“The speed at which pipelines are built is one of the more serious constraints in preventing impacts. Most big infrastructures take many years to plan and build. Completion of pipelines, on the other hand, often takes 24 to 36 months. This means it is even more important for the ESA of pipelines to begin as soon as the prefeasibility planning begins. Route selection, the main means of reducing impacts, is often one of the first items planned by the engineers. “
Being how I am blogging for a Valve Manufacture, I will save you some extra details about what a pipeline consists of. Depending on if you are an end-user, Mfg, or just a reader hoping to gain more info, you probably already know the different parts. Typically, you might see pipes, flanges, valves, fasteners, and of course many more parts. Some of the ball valves you might see would be the Trunnion Mounted Ball Valves. (This is our specialty)

Pneumatic Valve Actuators in Sub-Arctic Climates
“Sub-arctic climates experience temperatures from 100° F (38° C) in the summer to –60° F (–51° C) in the winter. While there is nothing spectacular about the high end of the range, the low end impacts the functionality of pneumatic actuators”
You may ask, how exactly does the temperature impact the pneumatic actuators that are in the fields right now? There are a few things you have to consider.
First, the actuator housing is steel, thus the housing becomes brittle. This does not necessarily mean it becomes weaker but a sudden impact or an imperfection can result in a sudden fracture at these temperatures because the temperature is below the brittle transition temperature of steel.
Secondly, the “precipitation-hardened shaft material has also become brittle and may fracture given an impact load. If, for example, the driven valve resists opening and then breaks free, the resulting sudden impact may cause the actuator shaft to fail.”
There are many solutions to these issues, but the best would be to call your actuator mfg to discuss how to avoid any fractures caused by these temperatures. Just like the manufacture should know what to do, the users of the actuators should know what to do as well. If you are not able to get in contact with your manufacturer, here are a few steps you can take:
“First, and most obvious, users should shelter the actuator from weather extremes where possible. Second, users must assure a dry air supply, at least 15° F (–9° C) below the lowest temperature that may be experienced since ice plays havoc with air flow and mechanical motion. Finally, users should assess the recommended actuator and whether all possible precautions have been incorporated by the supplier.”
Clearly, pneumatic actuators can perform their intended functions despite having to operate in extreme temperatures. However, they need to be designed and manufactured properly, and users need to take responsibility to keep them functioning correctly.

Enbridge new Pipeline expansion project
Not, all the pipeline projects are dead yet! I am hoping with the new election coming up, there will be new projects and new pipelines to build.
“Enbridge has secured commercial support to proceed with several projects designed to increase capacity on the Enbridge crude oil mainline system in Canada and the U.S. and to increase capacity on pipelines that serve eastern U.S. and Canadian refineries.”
“Elsewhere the installation of a new 35-mile, 20-inch pipeline twinning the existing Enbridge Line 17 (Toledo pipeline) will add 80,000 bpd of capacity to the Enbridge mainline system. The line is expected to be available for service in early 2013 at a cost of approximately $0.2 billion.”

Flanged Valves
The prosperity of the valve industry has been shown in many fields. Actually, there is great variety of the types of the valve. All these types are making their own contributions to the development of the whole modern industry. As we all know, Flanged Ball Valves are made to control the flow of gases, liquids and granular solids in many systems. In order to meet various requirements, valves are designed and manufactured with a wide range of the types, sizes, materials, working temperature and pressure and means of actuation and so on. At this moment, we take the type of the ball valve and gate valve out for a comparison. Learn more about flanged valves below.

Ball Valves – Are They Useful?
Ball Valves in our history, have always proven helpful in a variety of ways. Review the article below and let us know what you think. Enjoy!
Importance of Ball and Pressure Valves to Industry Today
Although the ball valve was invented in the 1950’s it is more used today than ever before in history. This valve made of a simple ball with a hole in it has found wide spread applications in the chemical, petroleum refining, paper making, water treatment plants, and many other industries.
The engineering beauty of ball valves and control valves from their simplicity. A ball with a hole in the middle sits inside passage way that fluid or air from passing through. When the ball is turned so its hole is in line with the pipe the fluid passes though, however when it is turned so the hole does not line up with the pipe the movement of fluid is stopped. This simple design allows ball valves to withstand temperatures of up to 200 degrees and pressures of up to 700 bars making them ideal for most industrial uses and easy to repair. The whole mechanism can easily be controlled by a handle outside the valve that can be turned 90 degrees.
Ball valves come in a large variety. There sizes range from as small as half of a centimeter to is much is 30 centimeters. They also come in five different body styles: split body, single body, top entry, three-piece body, and wielded. Despite the variety in ball valves, all ball valves work in much the same way.
Selecting A Butterfly Valve For An Application

Butterfly Valve
Used as a primary control device in fluid transfer applications, butterfly valves are preferred over most other types of valves for different reasons. Firstly, they perform a quarter-turn open/close operation, which is frequent, quick, and at less fluid resistance. Second, they display good flow control for a wide range of liquids, gases, suspended solids, and slurries. Lastly, they are compact, lightweight, and available in a wide range of materials, too.
The wastewater treatment, pharmaceutical, power generation, paper processing, food & beverage, and fine chemical industries utilize butterfly valves extensively. PTFE lined (FEP / PFA) valves are used in high corrosive chemical environments, whereas hygienic valves made from special types of elastomers are used in the food & beverage industry. Butterfly valves also come in fire safe designs to meet the safety requirements of the petrochemical industry.
Typically, butterfly valves come in sizes ranging from 1 to over 200. Their pressure capabilities range from 150 psi to 750 psi. Available in manual and automatically actuated modes, they are used as an on/off as well as controlling/modulating device. The seat material, body style (wafer or lug), and stem- design play crucial roles in selecting a butterfly valve.
Selecting the Right Style:
The most common types of body designs or mounting styles in butterfly valves are the wafer, lug, semi-lugged, and double flanged styles. While the wafer design is cheaper and safer, the lug style helps in removing downstream piping. Wafer styles attribute to the lightweight structure of butterfly valves, which ensures ease of installation.
Selecting Stem Designs:
The stem or shaft of a butterfly valve comes in one-piece or two-piece designs. While selecting a stem design for a high performance application, one must be aware of the fact that they have to be in contact with the fluid media and hence media compatible.
Selecting the Right Seat Material:
Being critical elements, seals, or seat materials, also determine the quality of a butterfly valve. A variety of factors, including chemical compatibility, pressure, temperature, cost, and wear is considered prior to selecting seats. PTFE (Polytetrafluroethylene) and RTFE (Reinforced Polytetrafluroethylene) are two commonly used seat materials known for their abrasion resistant, electrical insulation, and thermal properties. UHMWPE (Ultra-high Molecular Weight Polyethylene) is another popular material with excellent corrosion and chemical resistance used in the tobacco industry. The material is also ideal for low-radiation environments.
If the application involves a highly abrasive environment, inflatable seats that offer high wear resistance are used. Today, many applications require butterfly valves with FDA approved seat materials. Fire-safe, metal-seated butterfly valves are also popular choices today.
Selecting the Right Type of Butterfly Valve:
Butterfly valves are classified into three types based on their construction:
1. Resilient
2. High Performance
3. Tricentric
The resilient type of butterfly valves uses the rubber flexibility and hence used widely in applications that require lowest pressure ratings. They handle temperatures ranging from 25F to 300F. High-pressure applications use high performance types of butterfly valves as these valves provides a wear-free sealing. Temperature ratings for these valves range from 400F to 450F. Tricentric designs feature a metal seat, which can withstand tremendous amount of pressure and temperatures up to 1000F.
Selecting the Right Valve Size:
We can determine the right valve size by calculating the Flow Coefficient (Cv) of the butterfly valve. You can use the below formula to calculate the Cv:
Cv = GPM / √ΔP
Here, GPM is the max flow requirement and P is the maximum pressure drop. The valve size that is equal to the calculated Cv value is the correct size. If the needed Cv value is between two valve sizes, the larger valve size is selected.
