Gas shutoff valves control the flow of natural gas or propane through a hose. They are commonly used to shut off gas during repairs or emergencies. Gas taps are available in different materials and configurations, and buyers should consider size, temperature, pressure, flow rate, and material when choosing a fitting. A gas shutoff valve is […]
The oil and gas industry involves extracting hydrocarbons from the earth and transforming them into useful substances. It includes mining, processing, and transportation. The industry began in the 19th century and is divided into upstream and downstream operations. Upstream operations involve exploration and production, while downstream operations involve processing and transportation. Refineries are used to […]
Gas and electric ovens have subtle differences that can affect cooking certain foods. The choice ultimately depends on personal preference and cooking style. Gas ovens may be cheaper for those who do a lot of baking or grilling, heat up and cool down faster, and control temperature better. Electric ovens use dry heat more, but […]
Halon gas is used in fire extinguishing systems, with safer types replacing older versions. It quickly extinguishes fires without damaging objects and is popular in computer labs, museums, and libraries. Halon gas can produce toxic byproducts, and its manufacture was banned in 1994 due to environmental risks. Existing systems are still permitted to use halon, […]
Reformulated gasoline (RFG) is a fuel developed in the US to reduce pollution in highly smoky cities, mandated by the Clean Air Act. It significantly reduces smog and toxic pollutants emitted from vehicles without affecting performance. The use of RFG is connected to the federal reformulated gasoline program, which aims to reduce smog-forming emissions and […]
Gas flow sensors calculate gas volume in pipes or confined spaces by accounting for temperature and pressure. Various methods are used, including ultrasonic transducers, Coriolis flowmeters, and orifice gauges. Liquid flow sensors are simpler in design. Gas flow sensors must also consider the gas’s composition and use pressure controls and gas chromatograph spectrum analysis. Other […]
Respirator gas masks protect against harmful gases and chemicals, with filter cartridges designed to neutralize specific hazards. They are commonly used in laboratories, industry, and by military and police personnel. Proper use and specific filters are essential for full protection. A respirator gas mask is safety equipment designed specifically to protect the wearer from harmful […]
Ultrasonic gas flowmeters use sound waves to measure gas viscosity, density, and temperature. Three main types are transmission, Doppler shift, and open channel. They are less expensive and invasive than mechanical flow meters and can accurately measure gas properties. They have many applications in industries such as wastewater and petrochemicals and can measure non-conductive fluids […]
Gas solenoid valves use electrical impulses to control the flow of gas through a line or chamber. They can have one or multiple inlet/outlet ports and come in direct acting or pilot operated configurations. They are used in commercial and residential applications, such as pneumatic machinery, manufacturing plants, furnaces, and gas-operated dryers. A gas solenoid […]
Gas tungsten arc welding uses a tungsten electrode to create a clean weld with less contamination. It is used on thin and non-ferrous metals, requires a shielding gas and filler rod, and produces no smoke. Protective gear is necessary due to the high heat and UV rays. Gas tungsten arc welding is a type of […]
Gas cylinders are tall, narrow metal tanks used to store pressurized gases, including oxygen, helium, propane, and nitrogen. They are used in various industries and require strict regulations for storage, transportation, and testing due to their high risk and hazards. Cylinders have markings to identify contents, pressure, and manufacturer. They have a valve to release […]
Forklift gas, mainly composed of propane, is the most common fuel for heavy lift trucks. Gas forklifts are cheaper to buy but cost more to operate than electric models. They emit toxic exhaust and are designed for outdoor use. Despite this, they are popular due to portability, safety, and higher horsepower. Forklift gas is a […]
Gas ovens are more expensive to purchase but cheaper to run than electric ovens. They provide even heat and retain heat, but may require frequent turning of food. Gas ovens offer instant heat changes and wetter heat, but there is a risk of gas leaks. The decision to purchase a gas or electric oven is […]
Gas meters monitor the flow of fuel, such as propane or natural gas, and are used by utility companies to determine usage and charge users. There are different types of gas meters, each with a separate mechanism to measure usage. Gas volume is difficult to measure accurately due to changes in heat and pressure. The […]
Avgas is a high-octane fuel used in precision engines like airplanes and elite racing cars. It has a rating of 100 and lower volatility, making it suitable for high-altitude use. The fuel is identified by two numbers, denoting the octane rating in different fuel-air mixtures. Avgas is available in various grades, with unique dyes used […]
Hoagy Carmichael composed “Georgia on My Mind” in 1930, and Ray Charles popularized it in 1960 with his blues rendition. The song became the official state song of Georgia in 1979. Its origins are unclear, with some sources suggesting it was written for a sister named Georgia, while others claim it was suggested by saxophonist […]
The brown thrasher is the state bird of Georgia, chosen by school children in 1928 and officially adopted by the state legislature in 1970. These birds have reddish-brown feathers, curved beaks, and a large range of songs. They migrate to northern states in the summer and live in the southeastern, northeastern, and midwestern states of […]
Gas lift is a method of increasing oil well flow rates by injecting high pressure gas to reduce the weight of the liquid in the well column. It is compact and popular for offshore drilling, but other methods are cheaper for onshore wells. It can also be used in oil fields with high natural gas […]
Gas actuators use gas pressure to move a piston or similar mechanism for actuation. They are used in industries with a ready supply of gas, such as oil refining, and can provide linear or rotary outputs. Gas actuators are used in hazardous environments where personnel cannot operate mechanisms. They require a high-pressure gas source to […]
Wet gas is a gas with a fluid concentration of 10-15%, leaving it with a large amount of moisture that can affect its density and flow. Natural gas is the most common type of wet gas and can be turned into a liquid more easily than dry gas. The ratio of gas and liquid in […]
