Thermocouples are simple temperature sensors composed of two different materials that generate a voltage proportional to the heat they measure. They are available in different material combinations standardized into types. Amplifiers may be needed to read temperatures into a computer, and accuracy can be affected by several factors. With proper maintenance, thermocouples provide a cost-effective […]
Oxygen cutting involves adding oxygen to a cutting gas to increase the heat and fine-tune the flame for desired effects. It is a popular method for cutting and welding metal structures where electrical power is not available. Oxygen also saves gas and makes the flame burn hotter. The oxygen cutting torch is adjusted by regulating […]

Directional drilling is drilling for oil or gas in a direction other than vertical. It is done to preserve surface features or target specific subterranean features. It requires specialized equipment and can reach previously inaccessible sources. It is mostly used by the petroleum and natural gas industries, but can also be used for water or […]
Chimney mortar is used in fireplaces and needs to be heat resistant. Regular inspection and repair is important to prevent damage and instability. Homeowners can repair minor damage, but professionals should be called for major repairs. Chimney mortar is a type of mortar designed to be used in fireplaces. The process of applying grout to […]
The entablature is the section between columns and the roof of a building, consisting of the cornice, frieze, and architrave. Each section has a specific design and varies based on the style and height of the columns. The frieze is often the most decorative and can tell a story, as seen in the Elgin Marbles […]
Coated metal is created by adding a thin layer of dissimilar metals to a base metal, resulting in a stronger and more durable surface. Overlay, inlay, and contact cladding are different types of metal coating processes used to create coated metal objects with varying strengths and weaknesses. Coated metal is metal that uses a thin […]
Back pressure is the resistance and pressure in a pipe caused by changes in its environment, slowing down fluid movement. In computing, it refers to a buildup of data in a network switch. Water hammer is a momentary pressure change caused by fluid bouncing off a change in the pipe, while back pressure is the […]
The major diameter of a screw or bolt is the widest portion of the shank and is used to identify the size of the fastener. It plays a key role in screw identification systems, and can be measured using a micrometer. Suppliers provide charts to help identify screw measurements, including major and minor diameter and […]
Polyethylene plastic grades are distinguished by their density, which varies due to differences in crystallization structure, molecular weight, and branching. HDPE and LDPE are the most common types, used for packaging and films respectively. Other types include PEX, VLDPE, and UHMWPE, each with specific benefits. The density of polyethylene affects its environmental impact, but most […]
Medical device manufacturing produces equipment for medical diagnosis and treatment, tightly regulated due to the potential harm of device failure. Products must be approved by regulatory agencies before sale, and can include a wide range of equipment. Companies may sell directly to hospitals or through medical equipment suppliers, and trade associations work to promote safety […]
A socket weld flange is a pipe connector with a socket for welding, creating a strong connection without the need for grinding. It is ideal for small, high-pressure pipelines and chemical plants. The shoulder inside the socket ensures the pipe is seated with sufficient clearance, and the thick socket provides optimal flow. It is available […]
Laser beam welding fuses metal using a high-temperature laser, with two types of welding equipment available. The technique is popular in the manufacture of airplanes, automobiles, and spacecraft, but has some disadvantages. Laser welders emit a dense beam of photons to rapidly heat and fuse metals, with solid-state and gas laser welders used. The technique […]
Metal casting is an ancient technique where molten metal is poured into a mold and allowed to harden before being finished. Molds can be made from a variety of materials, including sand, clay, and wax. Metal smelting requires a foundry, which can handle different metals and alloys.
