There is no doubt, the search for more efficient methods of generating energy, and the ever-growing demand for it, are one of man-kinds greatest needs.
Recent developments in nuclear reactor technology have brought nuclear energy back into consideration. Small size nuclear fusion reactors have minimized the time, and costs associated with traditional nuclear power plants, along with reduced environmental and safety concerns.
However, oil and gas are not only used as a fuel source for vehicles and power plants, but they are also used in the manufacturing process itself. Petroleum based products are used in producing everything from plastics to various fabrics, and even used in the pharmaceutical industry, making petroleum sourced products more common than people think. Although great strides have been made in developing environmentally friendly renewable energy sources, traditional energy sources such as oil and gas are here to stay – at least for the foreseeable future.

Renewable energy projects are gaining momentum around the globe, and are a welcome addition to the ever-growing demand for energy. Wind energy is one of the methods used to supply some of the energy needs of the nations, while keeping the impact to the environment relatively low.
A critical component of an electricity producing wind turbine is the rotor hub. Made to carry the weight (Up to 30 metric tons on land and 100 metric tons offshore) and the tremendous forces exerted by the turbine blades while in full swing, the part must be made in a single cast piece of iron or steel.
After casting, the part has its mating surfaces machined to final specs.
HYDROELECTRIC POWER
Stainless Steel
Pelton turbines are very efficient devices that use the impulse of a water jet to drive an electric generator.
They are typically used in mountainous regions where the head (water level above the turbine) is relatively high and the flow is low. These Pelton turbines are commonly made of stainless steel, since they are constant contact with water.
YG-1 has a variety of tools designed for machining stainless steel, even the complex design of a Pelton turbine blades.

Modern day steam turbines are the heart of power stations around the world. A fuel source such as nuclear or fossil fuels heats water until it is converted to steam. This steam is then used to drive the turbine to produce energy. Steam turbines can be incredibly large, and their design complex, requiring the best grades of steel to be able to operate continuously even in challenging conditions.
YG-1 has the tools to meet the stringent machining requirements of the casing and shaft shown in the picture [below right] as well as tools for the turbine blades themselves.

Fracking, or hydraulic fracturing, is a relatively new method employed by the oil and gas industry to stimulate wells using a pressurized liquid. As fracking technology has developed and matured over time, it has become feasible to extract oil and gas from sources previously thought of as economically unprofitable, if not physically impossible. A modern day ‘ frac ’ pump has two main components, the power end and the fluid end.
The power end is the component that drives all the moving parts required to create the pressure in the fluid end.
The fluid end is the high pressure component of the pump that takes fluid into a chamber at low pressure and discharges it at higher pressure. Considered the ‘business’ end of the pump, it is made of a single billet of stainless steel, to withstand both high pressure, and resist corrosion.

Pipes create a crucial network for transporting petroleum-based products, as well as natural gas. From the huge pipes that span across entire continents, to the more modestly sized pipes carrying products within the refineries and storage facilities, pipes play a critical role in connecting everything together.
While most pipes are made through extrusion and/or welding, their adapters, flanges, and connectors have some form of machining involved in their production.
These pipe networks also incorporate various types of valves, which are typically cast and machined to their final dimensions when appropriate.
The larger diameter pipes are usually made of carbon steel, while the smaller ones are some variant of stainless steel to protect them from the corrosive environment in which they operate.
Occasionally, an even stronger material is required–this is where nickel-based superalloys such as inconel or hastelloy enter the picture.
NUCLEAR POWER
Stainless Steel
Heat exchangers play a critical role in the day-to-day operation of a power plant. This role is even more critical where the source of energy is nuclear. Simply put, the heat exchanger’s role is to transfer heat from one closed system to the other.
It is used in applications to condense steam, or as in the case of a nuclear power plant, to transfer heat between two loops of steam, from the irradiated, to the ‘clean’ loop. To avoid dangerous and costly contamination, it is imperative to follow strict guidelines and maintain precise tolerances when machining the components of a heat exchanger.
Stainless steel is the material of choice since it is highly resistant to corrosion, which is exacerbated to a large degree, in the presence of radiation.
YG-1 meets the challenge, with its product lines that are optimized for machining stainless steel.
