Generally, steel buildings refer to metal structures in which the members are made of steel in order to offer internal support as well as exterior cladding. The steel components of these buildings are generally joined by welding, riveting or bolting, and this reinforces their strength. The construction of steel buildings is usually accomplished through industrial processes. In modern construction, steel buildings are best known for the diversity of their shapes as well as their architectural expressiveness that make them more reliable than other types of structures. During this century, steel buildings have evolved into various specific types according to their use, which can be storage, places of work, living accommodation, and others.

Steel buildings offer several advantages. To begin with, due to the high strength of steel, the strength of these buildings is unmatched compared to structures constructed using other building materials. This is particularly essential when one desires to have a building with a strong foundation for use with heavy machinery. Next, steel buildings save time and money as compared to using conventional building systems. The inherent strength of steel implies that less structural members are required, and this translates to savings in construction, maintenance, and replacement costs. Other benefits of steel structures include increased sanitary conditions, environment conservation, and flexibility in case of alteration for different uses. On the hand, the main disadvantage of steel buildings is their susceptibility to corrosion. However, this can be surmounted easily through applying some protective measures, for example, applying special coatings and paints.

Recent reports of the oil boom in Williston, North Dakota is proof that even now, during one of the toughest economies of our time, there are markets booming and areas with tremendous growth potential. Now in order for the towns, companies, industries around these areas to maximize the profit potential of this boom they must too grow at a rate that can keep up with the growing demands.

For years, pre-engineered metal buildings have been the solution for quick cost effective construction. The constant demand for faster, stronger, easier construction for less catapulted the popularity of steel construction. Companies in industrial and manufacturing industries have long used steel framed metal buildings for their size, strength, and safety. Also, metal buildings come pre-engineered for fast construction and require little maintenance to minimize expenses and maximize profit margins.

Now, fast-forward to present day and steel framed buildings are being utilized for everything from homes and churches to auto-shops and retail stores. Choosing to build with metal is a no brainer expansion solution for the supporting retail and service companies of booming town like Williston the surrounding towns in N. Dakota because not only must companies in the oil industry must grow, but also the communities that support the oil industry workers and families. This means expanding neighborhoods, adding retail locations and services industries meeting higher demands.

While exciting, quick growth can also be daunting to business owners who are investing in new businesses or expanding a current business. Those in North Dakota are definitely feeling the pressure, as it’s hard to keep the retail and service jobs filled with the promise of big bucks in the oil industry. Not to be discouraged, eventually the oil positions will be filled and all of those workers will need clothing, groceries, gas and a place to go for entertainment; and the companies who prepared by opening or expanding a company in anticipation of this boom will to be prospering—through the trickle down economics of the situation. Metal building construction is faster and cost less, last longer, require less maintenance, and to top it off if you find yourself needing to meet the demands of more growth in the future they can be more easily expand upon than other building materials.

Butterfly valves are devices used for flow control, usually the flow of a fluid through a section of pipe. The butterfly valve operates similarly to an electric ball valve. A flat disc located at the pipe’s center has a rod running through it that connects to the actuator on the exterior of the valve. Turning the actuator rotates the plate to a position either perpendicular or parallel to the flow. The flow may be regulated more specifically through different disc rotations.

The “butterfly” is the metal disc mounted on the rod. When the valve is in the closed position, the disc is rotated to a position in which it totally blocks the passage of liquid. When the valve is open fully, the disc has been rotated one-quarter turn—90 degrees—allowing for nearly unrestricted passage. Flow may be incrementally regulated by various positions of the valve. This advantageous feature of butterfly valves makes them ideal for many industrial uses. The size of butterfly valves is one more of their advantages. Since they are lighter and smaller than other valve forms, they do not necessitate the large degree of supporting structure required for other valves, such as the electric ball valve.

The butterfly valve has a resilient seat, a body, a butterfly disk, packing, a stem, an actuator, and a notched positioning plate. When the resilient seat is mounted in the valve body, it is under compression and makes a seal around the edges of the disk and the lower and upper points where the stem runs through the seat. Packing provides a positive seal all around the stem for extra protection, should the seal made by the seat suffer damage.

Butterfly valves are available in different styles, such as high-performance and eccentric valves. Butterfly valves can be found on fire apparatus and large lines, such as tank to pump lines and rear and front suctions.

The design of the butterfly valve does give it a disadvantage, because unlike an electric ball valve, a portion of the disc will always be in contact with the liquid, regardless of whether it is in the open or closed position, and this causes a constant pressure switch regardless of the setting. Viscous or thick liquids also may slow the disc’s functional movement.

Though butterfly valves may be configured for electronic or manual operation, the most rapid is pneumatic control. The gearbox must receive a signal to both open and close an electric ball valve. However, an advantage to pneumatic operation lies in its flexibility, for it permits either double or single actuation. Single actuation requires a fail-safe, so that in the event of power loss, on a spring-loaded system, the valve will change to the closed position if open. So, a signal must be sent to open the valve initially. Double actuation valves need signals to both open and close the mechanism, because they are not spring-loaded.
