Ningbo equal diameter four-way connector

Ningbo equal diameter four-way, also known as four-way fittings, can be divided into equal diameter four-way and reduced diameter four-way. The connecting ends of equal diameter four-way fittings are of the same size, while the main pipe connecting size of reduced diameter four-way fittings is the same, and the connecting size of branch pipes is smaller than that of the main pipe. Welding cross is a type of pipe fitting used at pipeline branches, manufactured using seamless pipes, typically produced through hydraulic bulging and hot pressing. Ningbo equal diameter four-way is generally used in places where pipelines have branches. Due to its convenient and simple use, it is widely used in fields such as petrochemicals and mechanical manufacturing.
