Exporter of Equal Cross, Unequal Cross Pipe Fittings
An Equal Cross is a pipe fitting used to connect four pipes of the same diameter. It allows for an even and balanced flow of fluids or gases throughout the system. This type of cross fitting is commonly used in applications where all the connected pipes are identical in size and need to handle the same pressure and flow rate. The equal cross is perfect for industries like water treatment, HVAC systems, and other processes where maintaining consistent flow across all branches is crucial.
An Unequal Cross is designed to connect pipes of different sizes, with one or more branches having a larger or smaller diameter than the others. This fitting helps regulate the flow of fluids or gases through pipes with varying capacities, making it ideal for systems where pipes of different sizes are required. It is commonly used in industries like oil and gas, chemical processing, and power generation, where different flow rates or pressures are needed at each branch of the pipeline. The unequal cross ensures the efficient distribution of fluids while managing the variations in pipe sizes.
