The kind of fittings among others is. 1. EbowElbow fittings are the first type of fittings, elbow is a piping component that serves to bend the direction of the flow. Like a bend if we are on the road, the bend inevitably makes us turn in through it, so is the elbow that is tasked to bend the fluid flow. Elbow consists of the two most common types of 45 and 90 degrees. To gain angles in addition to the corners above, sometimes the elbow is cut. Or it could be by using two of the elbow that is merged to obtain a certain angle. The market, elbow is divided into two types, type of sort radius and long radius. Namum generally used long radius, which has a diameter turn 1.5 times NPS (nominal Pipe size). Some are up to 3D or even 6D, which is commonly used for flare. Elbow generally has the same diameter between the input and the output, although some have different sizes, which we call reducing elbow. In addition, there is one fitting component that resembles elbow, same as functioning to bend the flow, but made from the pipe piece, we call it with miter. 2. The fitting of TeeTee in the fittings in charge to divide the flow, is the connection fittings that have branches. Usually the branches are the same size as the main pipe sizes, we refer to them with straight tee. Whereas if different, we call it with reducing tee. As if on the road, if this tee we analogues as a T-junction. By the way about the T-junction, meaning not all of him should be perpendicular dong? True, indeed there is a tee that is not perpendicular, it forms an angle of 45 degrees. We are familiar with the lateral Tee, whose use is usually for low pressure. If there is a T-junction, then there is a crossroad also we know him with crosses. But the use of this crosses is very rare, intended only for limited space. 3. The ReducerReducer fitting, as the name of this type of fittings is tasked to reduce the fluid flow. Reduce here not like valve, but the size of the flat is reduced. So these reducers will be tasked to combines from larger diameters to small ones, or vice versa. In this reducer, we will know two types of reducer namely Concentrik Reducer and another is Eccentrik reducer. Both have different roles. 4. Stub-inStub-In, is a type of fitting whose function is similar to a tee, which is dividing the flow. The difference with the tee, if the tee is a separate item, he combines some pipes. But if the stub-in, the direct branch of the main pipeline that functions to reducing tee. 5. Fitting CapPipa caps fittings function to stop the flow at the end of the pipe, these fittings are in weld directly on the main pipe. There is also a fluid flow cover that can be disassembled and removable, but usually uses a flange connection, more precisely the blind flange.
