The Origin of V-Band Clamp Herbert “Zeppo” Marx is an actor, the youngest of the Marx brothers, often played straight man character，approximately enraged that he could not be funny, he left the team after only  5 movies to became an theatrical agent with older brother Gummo in running a skilled agency.  Zeppo also was inventor and engineer, developing Marman Products Business, Inc. of Inglewood, California as company owner. After founding Marman Products in 1941 which made these clamping devices, he posessed three licenses, two of them is relatived with his development of a watch that pay close attention to the pulse of heart individuals. This achievement made Zeppo a multimillionaire.                                                                           The significance of V-Band Clamp The v-band clamps barely attract people attention, but it is a very meaningful existence. It has been used in everything from ordinary trams to space vehicles. And even played a major role in ending World War II as it held the atomic bomb in transport aboard the Enola Gay bomber.   Why use v-band clamps With the arrival of every custom exhaust project, head, muffler, tube size, and metal type are all choices that can have a huge

Evolution History of Shaft Collars and Select a Proper Clamping Shaft Collar   Collar Evolution History  The first mass-produced shaft collars were used primarily on line shafting in early manufacturing mills. Early set screw collars were solid ring types that employed square-head screws that protruded from the collar. Protruding screws proved to be a problem because of their tendency to catch on worker’s clothing, pulling them into the machinery. Shaft collars saw few improvements until the early 1900’s when Howard T. Hallowell created the first recessed head socket set screw collar. Hallowell received a patent on his safety set collar, which was soon copied by others and became the industry standard. Since the screw impinges into the shaft when using set screw collars, using them is destructive to the shaft. As a result, the clamp-style shaft collar was invented to achieve greater compressive forces and holding power without damaging the shaft. It is uncertain who invented clamp-style collars, but they have been used since WWII where they were used in bombsights and guiding systems. At the time, clamp-style shaft collars were considered high-tech precision components, and they are still used in advanced systems with difficult requirements today. Shaft collars are one of the simplest components in machine design but are also one of the most indispensable. Shaft collars can be found in virtually any type of machinery and are frequently

NFPA 1963: Standard for Fire Hose Connections NFPA 1963 provides manufacturers with the latest industry guidelines for standardized couplings and adapters for fire hose connections.When it comes to manufacturing fire hoses, connections, coupling and nozzles, every detail counts. Failure of a component can have serious consequences for those at a fire scene. NFPA 1963: Standard for Fire Hose Connections details performance requirements for new fire hose couplings and adapters with nominal sizes from 3/4 in. (19 mm) through 8 in. (200 mm) along with the specifications for the mating surfaces. Requirements apply to:     Coupling assemblies and adapters     Screw-thread connections     Non-threaded connections     Fire hose nozzle gaskets and gasket seats Fire hose adapters are small but essential components that reduce fire truck weight and enhance readiness Fire trucks are often very, very big. Like giant toolboxes with wheels, these vehicles carry thousands of pounds of hose, tools, people, and water. Fire hose adapters and fittings are likely some of the smallest products on those engines, but they play an important role in reducing loads—and keeping firefighters ready for anything. Thread types dictate which hoses and equipment connect First, just what are hose couplings? Well, a hose coupling is simply a connector located on the end of a hose. It couples, or connects, with a hose, tap or water source and is typically made of brass, stainless steel or aluminum.

Carburization is One of Most Important Heat Treatment in Fanovo’s Product Line.  Case hardening is a process which involves adding a hard, protective shell to the outside of an otherwise soft steel. This process allows for intricately shaped metals to possess a strength and toughness that they otherwise wouldn’t be able to possess. One of the most sophisticated and common forms of case hardening is carburizing. This is a method which involves introducing steel items to carbon atoms. Looking to learn a little more about the carburization of steel? Learn more! This guide has everything you need to know. What is Carburization for Steel Parts. Carburization is a process which involves taking a low carbon steel and transforming it into a high carbon steel. This is done by exposing it to an atmosphere which is dense in carbon. Generally, items are carburized in furnaces, vats, and other enclosed entities. By heating a steel item in a carbon-dense atmosphere, said item will allow carbon atoms to attach to its surface on a molecular level. After these carbon atoms have attached to its surface, it will gain both hardness and strength. One of the most popular forms of case hardening, carburization can provide steel items with varying levels of hardness. Generally, the higher the heat, and the longer the duration of the carburization process, the harder the carburized item will be. Carburizing Steel

What Types of Sight Glasses are in Fanovo ?  Fanovo supply a wide range of sight glasses for viewing the contents and/or level of tanks, vessels or pipelines. Methods of installation are by welding, bolting or clamping into your equipment. Pressure ratings range from high vacuum, through atmospheric to high pressure applications. Temperature ratings range for cryogenic to furnace. Sizes range from 6 mm through to 600 mm. Materials available include aluminium, carbon steels, stainless steels, duplex stainless steels and hastelloy. Circular sight glass fittings  A sight glass, also called a sight window or view port, comprises two flanges, bolted together, surrounding a glass disc sealed with gaskets and provides a means of viewing the inside of a process vessel or tank. Typically used to visually verify stages of a process, inspect process media, and to observe liquid levels. Common applications include the viewing of internals of pressure vessels, tanks, silos, stirred vessels, separators pipelines etc. In addition to the sight glasses, Fanovo can also supply accessories such as a wiper, sight glass Luminaires, cameras and spare glass and gaskets. Sight flow indicators  A sight flow indicator is used in process pipelines to observe the flow of liquid, powder or gas. It is comprised of a body with one or more viewing windows. It is the most reliable way to verify flow for direction and approximate rate, colour and clarity.

What are the functions and purposes of sight glass? The purpose of a sight glass is to allow factory managers and engineers to look inside of their systems without disrupting the environment within. Often referred to as viewing glasses, they offer you a way to see the levels of liquids or gases that are traveling through a critical point of your design, monitor pressure changes, and virtually anything else that sight glass windows could allow you to do. With their widespread use, sight glasses have become critical to operations such as steam pipelines, chemical processing, pharmaceutical processing, and food processing. Often simple in design, rudimentary sight glasses of the past consisted of a glass tube that was linked to an important part of your system, like a tank or a gas inlet. Modern industrial sight glasses are made from a glass disk that’s securely held by bolts and gaskets between two metal frames, with the goal of maintaining the standards of sanitary fittings. The glass that’s used is typically soda lime glass or borosilicate glass, while stainless steel is the go-to choice for the metal due to its superior strength and abrasion resistance, even with 304 steel. It’s necessary for a sight glass to be able to withstand whatever materials and fluids it will come into contact with so that the glass does not tarnish or degrade, impairing your ability to use it for

The Type of Balancing Valve During commissioning of heating  and cooling systems, hydraulic balance is often achieved using balancing valves. Two types of these valves exist: static and dynamic balancing valves. Static balancing valves serve as a permanent resistance, built into the system.The settings for these valves must therefore be calculated and adjusted accurately, as changing just one of them in the system could change the flow through all other valves. Dynamic balancing valves work as flow limiters. They are set to a desired flow rate and ensure that a larger flow rate does not take place. If the pressure in front of the valve increases, it will close some more, so the pressure loss across the valve becomes correspondingly higher. This maintains the desired flow rate in the specific path.The inlet pressure for a dynamic balancing valve needs to be higher than a certain limit for it to operate properly. This means that the resistance at the most distant valve cannot be close to zero, as is the case with static valves. Balancing valves are available from numerous manufacturers. Some of these provide electronic measurement equipment that allows measuring the flow through their valves. This is done by measuring the pressure loss across the valve and calculating the flow according to the kv-value of the present position of the valve.

What is the most important When Selecting Shaft Collars for Equipments and Machines? There are a variety of factors that determine which collar is ideal for an application. It is important to carefully identify all the relevant requirements, parameters, and limitations of your system before selecting a shaft collar. All things being equal, the holding power of each style of shaft collar increases from left to right: quick clamping, set screw, thin line, standard clamp types, double wide, heavy duty, threaded/bearing locknut.   In many applications, holding power is the key performance factor designers are looking for. It is affected by a variety of collar specifications and affects the collar’s maximum axial load. A set screw collars  holding power is dependent on how much the screw can impinge into the shaft, which is a function of the relationship between the screw and shaft materials. Bore size and concentricity influence the holding power of Clamp style shaft collars , however the importance of fastening hardware cannot be understated. The size and quality of hardware, namely thread quality, tensile strength, and size tolerances, affect how much torque the screw can transmit to the collar. Forged screws are generally superior to broached screws as they are more consistent and are less likely to ream out. Likewise, the collar itself must be manufactured from a material strong enough to withstand the recommended screw torque or else it may
