Typically, piping designers set branches parallel to each other and connect them to the horizontal header pipe. As a result, valves and chokes provide isolation and metering on headers to satisfy the needs of the application. The flow rate value highly depends on the supply pressure and line sizes, and thus requires proper consideration. Also, in drainage applications, professionals set a threshold flow rate to avoid hold up at drains. To satisfy the production requirements in a facility, flow rates for each line must meet a set value or within a limit. All these elements require consideration when designing a header. In addition, there are pressure drops due to the presence of bends and tees on the header. The use of chokes and valve help mitigate this risk. Without proper design, a high-pressure branch could cause backflow into a lower pressure branch. On the other hand, for a collecting header, different sources flowing into a single header at diverse pressures also pose a challenge. As a result, engines can deliver measurably better horsepower, torque, and mileage. Moreover, their presence is necessary especially when aggregating fumes from multiple combustion chambers.

Exhaust Systems: Pipeline headers are common deployments for taking exhaust fumes out of engines.

Using this, operators can determine important flow details such as production rates and gas/liquid ratios.

Testing and Metering: In some applications, headers have testing and metering valves that direct fluids into testing vessels.

In addition, the headers serve as a means of distributing fluids that mitigate corrosion and hydrate formation to various sections of the piping system. This holds especially true in oil fields where the wells are widely distributed and some distance away from the processing facility. As a result, an exploration company can achieve significant savings on pipeline infrastructure.

Production and Distribution: In the oil and gas industry, headers serve to commingle flow from different wellheads into a single production pipe.

Typically, the design of flow systems with headers is due to a variety of reasons. On the other hand, it can also distribute flow to many smaller pipes (distributing header). Pipeline Header PurposeĪ pipeline header refers to a large pipe that is set up to aggregate flow from smaller pipes (collecting header).

In this article, you will learn the purpose of a pipeline header, important factors in its design, and calculation methodology. A pipeline header connects flowlines from several different sources into a single gathering line.
