Table Notes:

 

1. Material grades: 304 for general use, 316L for salt spray resistance, 321 for high-temperature resistance.
2. Surface treatments: Passivation is the basic corrosion protection; polishing is used for clean environments.
3. Fitting type selection: Y-type preferred for high pressure, T-type for right-angle installations.
4. Standards: Domestic standards follow GB series; international standards follow ASME.

 

 

 

 

 

 

 

 

An equal-diameter tee is a pipe fitting with three ports of the same diameter, usually arranged in a T-shape. It is used to connect three pipes of the same specifications to achieve fluid diversion or convergence

 

  Stainless steel equal diameter tee has many remarkable advantages, which make it widely used in many industrial and civil fields. First of all, it has excellent corrosion resistance and can effectively resist the erosion of various chemical media, which makes it excellent in the chemical, pharmaceutical, food processing and other industries to ensure the long-term stable operation of the pipeline system. Secondly, stainless steel equal diameter tee has high strength and high temperature resistance.
  At the same time, it can withstand high working pressure and meet the strict requirements of the pipeline system in industrial production. In addition, its long service life, almost no additional maintenance is required, greatly reducing long-term use costs, improve the economy of the system. In terms of hygiene performance, the stainless steel surface is smooth, not easy to breed bacteria, and meets the strict hygiene standards of the food and pharmaceutical industry, ensuring the safety and purity of the fluid transfer process.
  The processing and installation process is also very convenient, the use of advanced manufacturing processes, such as hydraulic expansion or hot forming, to ensure the dimensional accuracy and quality stability of the product, while supporting welding, flange connection or thread connection and other installation methods, can be flexibly selected according to actual needs.
  In appearance, stainless steel equal diameter tee has good luster and aesthetics, and can be polished or passivated according to customer needs to meet the aesthetic requirements of the occasion. At the same time, stainless steel materials can be fully recycled, in line with environmental requirements, reducing the impact on the environment.

Application And Usage

 

Taken together, these advantages of stainless steel equal diameter tee make it an indispensable component in modern pipeline systems, widely used in chemical, food, pharmaceutical, construction, oil, natural gas, environmental protection and other fields, providing a reliable solution for a variety of complex fluid transmission needs.
