equal tee fitting is a kind of tee. There are general equal tee and reducing tee. It is named because the three ends can be connected with the pipe.
equal tee fitting is widely used in the construction and maintenance of petrochemical, oil and gas, liquefied gas, fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food hygiene, urban construction and other industries. In industry, the pressure of this kind of pipe fittings is higher, the maximum pressure can reach 600 kg, and the pressure of water pipes in life is lower, generally 16 kg.
Because tee can be used in many industries, it can be divided into the following categories according to different types:
1. Divide carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PPC, etc. by material.
2. According to the manufacturing method, it can be divided into top system, pressing system, forging system, casting, etc.
3. Manufacturing standards can be divided into national standards, electricity standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.
1. Hydraulic bulging
The hydraulic bulging technology of the tee can be formed in one time with high production efficiency; the wall thickness of the main pipe and shoulder of the tee is increased.
2. Hot forming
Hot pressing of tee is to flatten the tube blank larger than tee diameter to the size of tee diameter
Equal diameter tee is a tee with the same diameter at both ends. Reducing tee is a branch pipe with different diameter from the other two. It is called reducing tee. The expression is as follows: for equal diameter tee, for example, "T3" tee is a tee with an outer diameter of 3 inches. For reducing tee, for example, "T4 × 4 × 3.5" means reducing tee with the same diameter of four inches and the same diameter of 3.5 inches.
The material is generally 10 × 20 × A3 Q235A, 20g, 20g, 16Mn, ASTM a234, ASTM A105, ASTM A403, etc., tee, the outer diameter range is 2.5 "- 60", from 26 "- 60" is welded tee. The wall thickness is 28-60mm.
The pressure rating is sch5s, sch10s, sch10, sch20, sch30, sch40s, STD, sch40, sch60, sch80s, XS; sch80, sch100, sch120, sch140, sch160, XXS.
