Refineries are booming every year
Refineries are booming every year
“Refiners are set to beat all except three of 154 industry groups on the Standard & Poor's index for 2012, as a U.S. production glut let them buy oil at a record average of $17.46 a barrel below the global benchmark. That spread will diminish in 2013 as more than 20 new pipelines enter service and route oil to new buyers along the Gulf Coast, Deutsche Bank AG forecast.”
“While transportation projects including oil-by-rail and pipelines are booming, providing a natural diversification for refiners, some of the world's most successful investors are betting that the companies have at least another year of gains.”
With that being said, Valero Energy Corp., a San Antonio refiner that may create a crude transportation unit, was named the top energy stock pick of 2013. As well as your other larger companies such as Philips 66. They plan to earn as much from pipelines and making chemicals as refining crude.

Pipeline Valves
There are many kinds of pipeline valves, review more information below.
Firstly, the structure differs. As we all know that a ball valve features the spherical closure element with a round or other-shaped hole in the middle and a gate valve features the lifting and dropping wedge. And the number of the holding ports varies. A gate valve has two ports, which is called an inlet and an outlet. But a ball valve usually has two or more ports. However, when referring to the connections to the ports, they would be with the same ones, including the threaded, soldered or Flanged Ball Valves.

Gate Valve Lubricant
Image via Wikipedia
Gate Valve Lubricant
The key functions of the gate valve lubricant are as listed:
- To provide an integral lubricating film between the gate, seat and
the threaded stem, where applicable. (The lubricant film must withstand the high interfacial contact stress between gate and seat surfaces.)- To displace corrosive chemicals and fluids from the valve cavity and provide a barrier to prevent further ingress of these chemicals, as well as contaminants such as sand.
- A high performance valve lubricant can also deliver secondary benefits by providing additional corrosion protection to the 'exposed' internal valve components; especially, if the metallurgy is underspecified.
- Restore valve integrity, by providing a sustained leak sealing capability.
Sealing Leaking Gate Valves
In some cases, the damage to the sealing surfaces is extensive, allowing the only remedy of replacing the damaged valve components. After the components have been replaced, immediately employ a high performance cavity lubricant, that is manufacturer approved for the installed gate valve.

Things You Use But Don’t Think About: Swing Check Valves & More
If you're like most people, you probably use a lot of tools each day without knowing exactly how they work. In an era of increasing specialization, it's impossible to learn about and understand the details of all the gadgets and comforts that make up modern life -- from making a call on your cell phone to riding an elevator to swiping a debit card to flushing a toilet. Here are some inventions that, while often uncelebrated, play important roles.
Elevator Brakes
Without elevators, the tall buildings and skyscrapers of today wouldn't be feasible. Imagine climbing 100 stories of stairs every day? That's not a trip you would want to make every day. Though elevators have been used for thousands of years, it wasn't until the 19th century that they began to be safe enough for human transport. And as elevators continued to become a safe and viable way to move up and down, cities and life for the city dweller began to change.
In 1853, a man named Elisha Otis invented a braking system that caused the elevator to lock into place if the rope or cable holding the cab broke, preventing the cab from falling. Many credit his simple invention of a braking safety system as key to the development of the modern city.
Vacuum Pumps
This nifty device was first invented in 1650 by Otto von Guericke, and involves removing gas molecules from an area in order to create a vacuum. You may not know it, but you rely on vacuum pumps to serve you in multiple ways. When you flying, vacuum pumps can play crucial roles operating flight instruments. Do you have a gallon of milk in your fridge? Vacuum pumps are used in milking machines that dairy farmers use. Vacuum pumps can also be used to power suction devices used by dentists, in medical devices and much more.
Check Valves
This device is designed to allow for the movement of fluid in one direction while blockings its flow in the opposite direction. Check valves are often used in industrial settings, including chemical and nuclear plants, but they also have uses at home.
For example, check valves (also known as backwash valves) can be used in pool filtration, allowing debris to enter into a pool, but not back out. They are also used in sump pumps, keeping the water that you may have to pump out of your flooded basement or crawl space from reentering. There are multiple check valve designs, including the ball check valves, swing check valves, among others.
The life we live is built upon a foundation of curiosity, creativity, and necessity which has led the legions of inventors to find new ways to shape the way we live and interact with each other.

Spherical Perfection In Steel Balls
Steel balls look like classy marbles. The shiny gleam and the glassy surface make them ideal as a play-toy, but that is not what they are used for--largely not anyway. Instead, a steel ball is one of the most important features in applications like antilock brakes, ball bearings, CV joints and seatbelt locks. In general, steel is the choice material for ball construction in the automotive and aerospace industry.
Steel outperforms other metals used to make balls such as chrome or tungsten carbide for its noncorrosive properties, hardness and cost efficiency. While chrome has many useful applications, it cannot be placed in environments where it is likely to often be wet or subject to fluid contamination. Though tungsten carbide is far harder and noncorrosive, its sheer expense makes it unavailable for most applications.
Steel is the ideal medium. Steel is swell resistant at only 6.4 microinches, per inch, per degree Fahrenheit. Simply stated, in a hot combustion engine, steel balls will not swell to larger sizes and cause abrasion to their components.
Chrome and aluminum both swell more than twice as much in the same heat equations does. Again, tungsten carbide is more resistant but at a high cost.
Steel balls are the choicest product in their many applications. Many people are unaware of the numerous places where steel is the select material, and where balls are placed. For simple rolling appliances like hospital curtains, balls are used in most patient rooms. Everyone who has used a ballpoint pen has enjoyed the noncorrosive factors of steel for smooth writing. People whose lives have been saved by a seat belt locking in a bad car accident can thank steel. The metal is simply the most effective medium for the most useful shape: the sphere.
Numerous companies provide balls made from every material from glass to aluminum and of course, steel. Commonly, companies provide sizing-charts for clients to order, ranging from 1/64th of an inch to three inches. Smaller sizes are utilized for pen points while larger balls are used in pivot joint machinery like a sprinkler system. Special orders and companies with broader scoping machinery produce balls up to six inches in diameter. These larger sizes are most commonly utilized in airplane wing-flaps or as ball bearings for semis.
Only tungsten carbide has the ability to valve-stop gas piping for industries like Halliburton or Schlumberger, making it the winner of that competition. For the rest of the industry, there is steel, steel or steel. The most versatile metal known to man is steel. The most useful shape is the sphere. The two combine to make one of the most unassuming, and profound products on the market. The next time a person turns on his or her car, he or she should thank steel balls for the safety they have provided all these years.

Ball Valves – Flanged Valves for Pipelines
Ball Valves
Global Valve and Controls main objective is to provide the industrial market with valves of the highest quality, performance and reliability; while still being cost effective. Therefore, the GVC ball valve continues to be researched and developed, making Global Valve and Controls one of the leaders in cutting edge technology and R&D. The GVC ball valve incorporates high quality TFM seats, investment cast up to eight inch, solid balls and a live loaded stem design as standard features to our line. These features are included at no addition cost, bringing our customers the highest quality valve at the lowest total cost of ownership.
The GVC Media Containment Bonnet, used in addition to our ball valve, controls fugitive emissions from being released into the earth’s atmosphere and prevents costly downtime.
Global Valve and Controls offers a vast variety of precision machined, solid balls which include but are not limited to, Alloy-20, Monel, Hastelloy-C, Stainless Steel and Duplex Stainless. The ball also has a mirror finish to prevent leaks which provides a bubble tight shutoff, reducing the torque or the force needed to stroke or cycle the valve. To reduce seat wear and ensure GVC valve reliability for a high cycle life, the ball edge has blended curvatures. In order to stabilize pressure between the GVC ball body cavity and the pipeline’s media flow, a ¼ inch hole is drilled into the stem slot to relieve cavity pressure thus providing an additional safety feature.
Body
Global Valve and Controls valve bodies are available in forged steel (up to 48”) and investment cast up to eight inch. Each GVC body casting or forging has a heat code which is marked for full trace ability. Certified Material Test Reports are available upon request.
Global Valve and Controls manufactures its valves in accordance to API 608, API 607, API 598, API 6D, B16.34, B16.5, B16.10, B16.25, NACE MR01-75 and our clients special requirements.

Global Valve and Controls offers various types of end connections such as raised face(RF), ring type joint(RTJ), threaded ends, socket weld ends, and butt weld ends.
Please contact the factory for more details.
Stem Assembly
To ensure a positive contact, Global Valve and Controls manufacture its ball valve’s stem to be match mated with the ball and body. All GVC stems are design blow-out proof bottom entry for maximum safety.
The Global Valve and Controls live loaded stem design is a standard feature on the following valves; Series FS150/300, Series E1-150/300, Series FSD61, Series FS525, Series FSD525 and Series GVD20.
This design utilizes a stem seal arrangement where the seals are retained by a stem or packing nut, also include live loading of the stem seals. This live loading is accomplished by the addition of Bellville springs below the packing nut. The purpose of live loading the stem seals is to maintain the initial sealing load on the seals as they wear, or as they compress further, reducing or eliminating the need for packing nut adjustments. The Bellville springs perform this function by storing compressive force or potential energy as the packing nut is tightened, and releasing this force as the packing wear or compression occurs.
Live Loaded Stem Packing
Valve sizes 1/4" through 4' Models 525, E1, and FS feature strong large diameter stems with live-loaded, self adjusting sealing utilizing Belleville washers which automatically adjust to compensate for changes in temperature and wear patterns. Manual adjustments, which can cause damage to the seal and seat, are not required. The assembly is secured by a saddle-type lock and washer which prevents stem nuts from unthreading in high-cycle automation applications.
Stem Packing
An adjustable V-ring design creates a multiple seal between the stem and body. Each stem assembly is composed of three or four (dependant on valve size) TFM or graphite rings providing a very high cycle life by resisting creep and cold flow. The Peek Thrust Bearing and the Peek Thrust Washer combine to provide a secondary seal, reduce torque, and prevent galling.
Global Valve 525, E1, 2T/3T Series and FS Series valve stems feature anti-static grounding devices as standard. The devices ensure electrical continuity between valve ball, stem, and body, thus eliminating the possibility of static electric charges creating sparks within the valve.
Stem Design: Valve Size 6" through 12"
The stem is guided by the valve body and the gland, ensuring smooth operation even in high torque service. The independent packing gland can be easily adjusted without removing the mounting hardware or operator. The user friendly packing gland and gland sleeve are V-slotted to more equally distribute the load in the event one side is over tightened. For severe applications, optional Belleville washers can be added for self-adjusting live load, providing a continuous compression seal and anti-vibration protection.
Seat Design
Global Valve and Controls' valves are offered as standard with resilient seats which ensure bi-directional, bubble tight sealing while providing the lowest possible torque. These specially designed resilient seats feature relief holes or slots to relieve pressure past the upstream seat. This design reduces friction, minimizes seat wear and lowers operating torque. Global Valve and Controls' seats feature optimally designed curvatures to minimize contact forces between the ball and seat when the valve is in the open position. This design prevents cold flow, lowers torque, and reduces wear.
Media Containment Bonnet
In the event of a stem leak that cannot be corrected, Global Valve offers a Media Containment bonnet which easily mounts to standard valves. These units prevent costly downtime and allow maintenance to be scheduled when convenient. The Media Containment bonnet can be provided with a button-head check valve for injection of sealing agent. Also, this unit is an excellent, cost effective way to provide double stem sealing to address emission control requirements.
