Fittings are components that act as an adapter to join different items together in various systems. There are different types of these modules, which bind together several items. Some of them are designed to reduce the flow, while some help to change its direction. Each of them has its own unique function, which helps in maintaining the integrity and functionality of the entire system. All of them can be availed in a wide range of sizes, which makes them highly versatile.
Forged fittings are components that are produced from various carbon and stainless steel material. During this process, the items are subjected to a heavy press creating, deformation in them. This helps in creating some important mechanical properties within these products of diverse shapes and sizes. A forged product has no cast-away defect, which is commonly seen during the metal smelting process. They optimize the microstructure of the component as they use hot-billets to form some of the best products. The billets are put under extreme pressure under dies Further they are trimmed and shot blasted to achieve the desired shape. These products are very durable and can be reliable in wide range of climatic conditions. Apart from this, they provide excellent sealing within the system, which helps in preventing leaks.
What is ASME B16.11?
ASME B16.11 is the standard, which is used while producing forged fittings. These components include socket and threaded types fittings. These components are available in carbon, alloy, and stainless steel products. Items ranging in pressure classes between 2000, 6000, and 9000 are generally designated for this grade. Utilizing forging machines, these modules can be availed in the form of tees, elbows, couplings, etc. They are normally forged from solid blocks of steel, which are machined to shape the final output giving it different shapes and enhanced tolerances.
Uses and Applications
These components are used in connecting different types of pipes, valves, pumps across different systems. They are critical in creating a piping system, which is 2 or 4 inches in diameter. The unique design along with the consistency and long service life makes them a preferred choice in different industries. These high-pressure fittings with zero defects can be utilized across all industrial applications. They are widely used in marine engineering, petrochemical plants, nuclear power systems, chemical processing, heat exchangers, manufacturing units, oil and gas industry, pharmaceuticals, construction, paper production, etc.
Socket weld vs threaded
The items in this range include two major fitting types, namely socket weld, and threaded items. Both these components are used across different systems. However, they both have certain differentiating parameters. Let us look at some of the key parameters.
The fittings in this grade utilize a threaded opening, which corresponds to the thread on the pipe. These connections are suited for low-pressure applications and can be assembled easily. They don’t require any additional welding processes and can be dismantled easily. However, welding may be necessary to affix certain high-risk items.
These fittings are placed in a recessed area of a pipe or tube. They are socketed ensuring, that they have a spigot end at the ending of the pipe. The items are used in high-pressure applications that are fixed and don’t require to be dismantled. The attachment to the pipe is done using one or two fillet welds.
When would you use socket weld material?
The fittings in this range are used for products, which require to withstand extreme pressures and elevated temperatures. The risk of leakage using these modules is comparatively less due to its strong seal. Apart from this, the construction costs of these items are less in comparison to butt-weld joints. And they possess similar tolerances to the same but without requiring additional preparation. They can be easily slid into a bevelled area of a pipe, which means that they don’t require weld preparation. In addition, the weld used to bind it would not penetrate to the bore of the pipe.
