Since their introduction to the market more than 50 years ago, triple offset valves (TOVs), which are also known as triple eccentric valves, have continued to evolve, while uses for this type of valve have expanded across multiple industries. Originally designed for water shutoff applications, design enhancements through the years placed this versatile valve among other industry staples for ...
A spring pin is a hollow, split dowel pin that exerts uniform outward pressure when fitted into a nut or shaft hole. Also called a roll pin, the spring pin withstands side loads and rotational friction, making it ideal for securing shaft and axle connections. Spring pins are also easy to insert and remove.

The type E spring is set above the supporting steel or can be welded directly to the supporting steel from below. Type F: The spring support is designed to support piping from below, directly from the floor or supporting steel. Adjustment is made by inserting a bar into holes in the load column and turning the load column as a jackscrew.
Pressure cooking is the process of cooking food at high pressure, employing water or a waterbased cooking liquid, in a sealed vessel known as a pressure pressure limits boiling, and permits cooking temperatures well above 100 °C (212 °F) to be reached. Pressure cookers work by expelling air from the vessel, and trapping the steam produced from the boiling liquid inside. This ...
Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Tempering is usually performed after quenching, which is rapid cooling of the metal to put it in its ...
The Alfa Laval LKC2 nonreturn valve consists of an upper valve body, lower valve body, valve plug, seal ring, and guide disc. The valve body is assembled by means of a clamp and hygienically sealed with a special seal ring. A guide disc and four legs guide the springloaded valve plug with an Oring seal.

Jan 19, 2017· Rocks. Iron ore [red rocks] is loaded into a bessemer furnace along with limestone, coke [pure carbon chunks], and some scrap iron/steel. The ore {iron oxide] is ''reduced'' back to pure iron [unoxidised] with a lot of heat and pure oxygen [blown up...
Safe Product Selection: The complete catalog contents must be reviewed to ensure that the system designer and user make a safe product selection. When selecting products, the total system design must be considered to ensure safe, troublefree performance. Function, material compatibility, adequate ratings, proper installation, operation, and maintenance are the responsibilities of the system ...
The difference between the forces seen at the two extreme rod positions named P1force and P2force respectively is an important gas spring characteristic and called Kfactor (IGS) or gas spring progression. When compared to mechanical springs, gas springs can achieve very low KFactors, typically ranging from to (or %80% progression).
Company structure: Swagelok Austria (AASolutions ) is a subsidiary company of Swagelok Switzerland (ARBOR Fluidtec AG).
The substitution of steel for iron as the material for rails which made possible the axle loads and the speeds of Ltoday, and, by reducing the cost of maintenance, contributed enormously to the economic efficiency of railways, was one of the most important events in the history of railways, and a scarcely less important element of progressive economy has been the continued improvement of the ...
Spring steel is a name given to a wide range of steels used in the manufacture of springs, prominently in automotive and industrial suspension applications. These steels are generally lowalloy manganese, mediumcarbon steel or highcarbon steel with a very high yield allows objects made of spring steel to return to their original shape despite significant deflection or twisting.
Compression Spring Stress. The dimensions, along with the load and deflection requirements, determine the stresses in the spring. When a compression spring is loaded, the coiled wire is stressed in torsion. The stress is greatest at the surface of the wire; as the spring is deflected, the load varies, producing a range of operating stress. Stress and stress range govern the life of the spring.
Stainless steel is an ironcontaining alloy—a substance made up of two or more chemical elements—used in a wide range of applications. It has excellent resistance to stain or rust due to its chromium content, usually from 12 to 20 percent of the alloy.
The defacto material is the 316/316L grade of austenitic stainless steel. This material works well to fight corrosion from a host of sometimes nasty fluids. For some tougher corrosive applications, more protection is needed. Other highperformance grades of austenitic stainless steel, such 317, 347 and 321 are often chosen in these situations.
