The equal tee is one of the pipe tees. The three pipes of the equal-diameter tee have the same caliber.

Equal-diameter tee is widely used in the construction and maintenance of petrochemical, oil and gas, liquefied petroleum gas, chemical fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food hygiene, urban construction, and other industries. In the industry, the pressure of such pipe fittings is relatively high, the maximum pressure can reach 600 kg, and the water pressure in the living is low, generally 16 kg.

Because the pipe tees can be used in a variety of industries, they can be divided into the following categories by different types:

Divided by the manufacturing material can be divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, and so on.

Divided by the production method can be divided into the top system, pressing, forging, casting and so on.

According to the manufacturing standards, it can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, and Russian standard.

The equal tee is the same diameter at both ends, and the method is as follows:

For example, the “T3” tee indicates that the outer diameter is a 3-inch equal-diameter tee.

The material of the equal-diameter tee is generally 10# 20# A3 Q235A 20g 20G 16Mn ASTM A234 ASTM A105 ASTM A403, etc.

The outer diameter of the equal-diameter tee ranges from 2.5″ to 60″, and the 26″-60″ is a welded tee. The wall thickness is 28-60mm.

The pressure levels of the equal-diameter tees are Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS.
