The following are common types of tee fittings: Malleable iron tees—primarily used in indoor heating, water supply, and gas piping systems. Their material and specifications are identical to those of malleable iron elbows. This ball-seat design is suitable for standard environmental conditions. Cast iron tees—made from gray cast iron. They share the same common standards and pressure ranges. Depending on the connection method, there are two types.
The following are common types of tee fittings: Malleable iron tees—primarily used in indoor heating, water supply, and gas pipeline systems. Their material and specifications are identical to those of malleable iron elbows. This ball-seat design is suitable for general-purpose applications. Cast iron tees—made from gray cast iron. They share the same common standards and pressure ranges. Depending on the connection method, there are two main types.

These include socket-type cast iron tees and flanged cast iron tees. Cast iron tees are primarily used in drainage pipes. Typically, 90-degree tees are employed in water supply pipelines to minimize fluid resistance and prevent pipe blockages. In contrast, drainage pipes generally use 45-degree inclined tees. High-pressure tees come in two main types, one of which is the welded high-pressure tee.
Another type is the integral cast high-pressure tee and the welded high-pressure tee. These tees have certain environmental requirements during operation. Typically, high-quality high-pressure steel pipes are used as the material. The manufacturing process is similar to that of bent pipes. Strict welding quality control, pre-weld heating, and post-weld heat treatment are identical to those applied to high-pressure elbows.
For the compression molding process of tee fittings, preparers must master the procedures and techniques involved in preparing tees and other pipe fittings, and ensure that all necessary equipment is ready. Loading and Heating: Place the tee billets into a natural gas heating furnace, using bottom gaskets to separate the billets from the furnace car. Also, straighten the tee pipes at intervals of two meters or more.
