A branch pipe with a diameter different from the other two is called a variable diameter tee or a reducing tee, while a pipe with the same diameter at both ends is called an equal diameter tee.
The main materials include carbon steel, alloy steel, stainless steel, duplex steel, nickel based alloys, etc.
Variable diameter tees are widely used in the construction and maintenance of engineering projects in industries such as petrochemicals, petroleum gas, liquefied gas, fertilizers, power plants, nuclear power, shipbuilding, papermaking, pharmaceuticals, food hygiene, and urban construction.
Variable diameter is a commonly used type of three-way pipe fittings, which has the following characteristics:
1. Has excellent performance. The thin oxide film on the surface of stainless steel gives it excellent properties in all water types, and even when buried underground, it has good corrosion resistance. It is suitable for various types of water quality, and does not require water quality control. There will be no corrosion or excessive exudate, which can maintain pure and hygienic water quality and prevent secondary pollution.
2. Stress resistance. Stainless steel water pipes have extremely high strength, twice that of galvanized pipes, three times that of copper pipes, and 8-10 times that of PP-R pipes. They can withstand vibration and impact well, and have characteristics such as no leakage, no bursting, and seismic resistance, making them very durable.
3. Long service life. Field corrosion test data shows that the service life of stainless steel water pipes can reach 100 years, and stainless steel water pipes require almost no maintenance, with a very high cost performance ratio, low cost investment, and significant economic benefits.
