A straight tee means a tee of pipe fitting which the branch outlet has a 90 degree direction turning from the main pipe of the tee.Commonly people consider the straight tee as the equal tee,it is a mistake.Equal tee means a same sizes of the branch and main pipe of a tee.
Tee is a type of pipe fitting,it is T-shaped with two outlets,the two outlets are 90° direction change to the main line.It is widely used as pipe fittings to connect pipelines with a pipe at a right angle,and are extensively used in pipeline networks to transport two-phase fluid mixtures. We mainly produce equal tee according to:ASME,ANSI,API,EN,BS,DIN,JIS,KS,GOST standards etc.
When we call a steel tee “equal tee”,means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.When we see only one size of tee in its description,it means this tee is the equal tee.For example, 4″ Tee mean the tee main pipe and branch pipe both are 4 inches.Sometimes the equal tee also described 4″X4″ which is the same meaning of 4″ tee.
