Equal diameter tee is a type of tee. The three pipes of the equal-diameter tee are equal in diameter.

As a general term, tees are pipe fittings and pipe joints, which are used at the branch of the main pipeline. Equal diameter tee is a type of tee. There are two types of tee: general equal diameter tee and reducing tee. It is named after the three-terminal can be connected to the pipeline.

Equal diameter tee is widely used in the construction and maintenance of petrochemical, oil and natural gas, liquefied gas, fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food hygiene, urban construction and other industries. The industry has high pressure requirements for this kind of pipe fittings, the maximum pressure can reach 600 kg, and the water pipe pressure in life is relatively low, generally 16 kg.

Because tees can be used in many industries, they can be divided into the following categories according to different types:

1. Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon immersion, ppc, etc.

2. According to the production method, it can be divided into topping, pressing, forging, casting, etc.

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

Equal diameter tee means that the diameters at both ends are the same, and reducing tee means that the diameter of the branch pipe is different from the other two, which is called equal diameter tee. The expression method is as follows: Taking the equal diameter tee as an example, the "T3" general rule refers to an equal diameter tee with an outer diameter of 3 inches. For example, for a reducing tee, "T4 x 4 x 3.5" refers to a 4-inch reducing tee and a 3.5-inch reducing tee with the same diameter. Generally use 10 # 20 # a3q 235 a 20g 16mn ASTM A234 ASTM A105 ASTM A403 and so on. Tee from 2.5" to 60" OD and welded tees from 26" to 60". Wall thickness 28-60mm.
