Table Notes:

 

1. Material grades: 304 for general use, 316L for salt spray resistance, 321 for high-temperature resistance.
2. Structural features: Equal crosses require symmetrical port alignment; angled types reduce fluid resistance.
3. Manufacturing processes: Hydraulic bulging (DN≤300) or hot pressing (large diameters), with strict wall thickness control.
4. Standards: Domestic standards follow GB series; international standards follow ASME. Special industries may require custom finishes (e.g., food-grade polishing).

 

 

  Stainless steel equal diameter four-way is a pipeline connection with four interfaces of the same diameter, mainly used to achieve multi-direction fluid distribution, common in chemical, construction, Marine engineering and other complex pipeline systems. It is made of 304, 316L, 321 and other stainless steel materials, of which 304 has universal corrosion resistance, 316L is suitable for Marine or chemical environment because of its resistance to chloride ion erosion, 321 can withstand high temperatures of up to 800ºC.

 

  Stainless steel equal diameter four with its full symmetrical structure design and high-quality stainless steel material characteristics, with excellent comprehensive performance advantages. It is made of 304, 316L, 321 and other corrosion-resistant stainless steel, which can maintain stability in a wide temperature range of -196 ° C to 800 ° C, and 316L material can resist the erosion of Marine salt spray and chemical media. By optimizing the wall thickness and flow channel design, the product can withstand high pressure conditions above PN16 to PN100, and the inclined four-way type can effectively reduce the fluid resistance. Multi-specification connection (welded/threaded/flange) for different installation scenarios, surface polishing, passivation and other processing processes to improve corrosion resistance and cleanliness

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.
