An equal diameter tee is a type of tee fitting. Tees are divided into two categories: general equal diameter tees and reducing tees. It is named for its three ends that can be connected with pipelines. Equal diameter tees are widely applied in the construction and maintenance of engineering projects in industries such as petrochemical, oil and natural gas, liquefied gas, chemical fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food hygiene and urban construction.

This type of pipe fitting bears high pressure requirements in industrial applications, with the maximum pressure reaching 600 kilograms. For domestic water pipelines, the pressure requirement is relatively low, generally 16 kilograms.

As tees are applicable to multiple industries, they are classified into the following categories by different criteria:
1. By material: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, etc.
2. By manufacturing method: push forming, press forming, forging, casting, etc.
3. By manufacturing standard: Chinese National Standard, Electric Power Standard, Water Supply Standard, American Standard, German Standard, Japanese Standard, Russian Standard, etc.

An equal diameter tee refers to a tee with the same diameter at both ends, while a reducing tee is defined as a tee whose branch pipe has a different diameter from the other two ends. The representation method is as follows: For an equal diameter tee, for example, “T3” indicates an equal diameter tee with an outer diameter of 3 inches. For a reducing tee, for example, “T4×4×3.5” means a reducing tee with a straight diameter of 4 inches and a branch diameter of 3.5 inches.

Common materials include 10#, 20#, A3, Q235A, 20g, 20G, 16Mn, ASTM A234, ASTM A105, ASTM A403, etc. The outer diameter range of tees is 2.5 inches to 60 inches, among which specifications from 26 inches to 60 inches are welded tees with a wall thickness of 28mm to 60mm.
