Pipe cross is also called cross fitting ,it looks like a tee but pipe cross has four ends . Think about a new branch pass through a equal tee, it is a cross .
Commonly, a pipe cross has one inlet end and three outlet ends, sometimes it is three inlet ends and one outlet end.The cross can not control the flow direction by its shape, So the four ends of the cross commonly are only one inlet and three outlets, or one outlet and three inlets.
The Pipe Cross is divided into the following two kinds: Equal Pipe Cross and Reducing Pipe Cross.
The equal pipe cross is one kind of the pipe cross, just like a equal tee, the equal cross means all the 4 ends of the cross are in same diameter. The pipe cross, like a road cross, is the joint of 4 pipes. Receiving the pressure from the 4 pipes, the weld joint between the pipes and cross must be very strong.
Because of the structure and flowing way of the cross, it is the center of four pipes connection .If there is any change of temperature in the cross point, it will bring a high pressure to the joint the cross. The cross tee has another feature that the products cost is very high ,more than two times price to the tees, so it is not used very popular.
The reducing cross also is called unequal pipe cross , it is the pipe cross which the four branch ends are not in the same diameters. just like a unequal tee, the reducing cross connect the pipes of different diameters.
Since the pipe cross has four ends, when describe a reducing cross people should indicate all the four ends diameters and their positions, or else it may bring som misunderstanding.
