Description

A lined unequal tee is a type of pipe fitting used in plumbing and industrial applications. It is called “unequal” because it has three openings of different sizes, with one end of the tee being larger than the other two. The larger opening is the “run” while the two smaller openings are the “branches”.

The term “lined” refers to the fact that the tee is coated with a lining material, typically made of a thermoplastic material such as polyethylene or polypropylene. This lining is added to the tee to provide additional protection against corrosion and chemical damage, which can be especially important in applications where the fluid being transported is highly corrosive or aggressive.

Lined unequal tees are commonly used in chemical and petrochemical industries, as well as in other industries that require the transport of aggressive or corrosive fluids. The lining material provides a barrier between the fluid and the metal of the fitting, which helps to protect against corrosion and prolong the life of the fitting.
