Material

JIS B2311 Tees are manufactured using a variety of materials to suit different industrial needs:

• Carbon Steel: For high strength and cost-efficiency.
• Stainless Steel: For corrosion resistance and enhanced longevity.
• Alloy Steel: For applications requiring added mechanical strength and heat resistance.
• Copper, Brass, or Nickel Alloys: For specific applications requiring enhanced thermal or corrosion resistance.

Type

1. Equal Tee: Both branch and run pipe diameters are the same.
2. Reducing Tee: The branch diameter is smaller than the run diameter, used to connect pipes of different sizes.
3. Barred Tee: Common in piping systems requiring flow control or filtering.

Corrosion Resistance

• Tees made from stainless steel or alloy steel offer excellent corrosion resistance against harsh chemicals, high temperatures, and moisture.
• Proper surface treatments like galvanization, electroplating, or powder coating enhance the corrosion resistance of carbon steel tees.
• Corrosion resistance ensures durability in applications involving corrosive media, such as chemical processing plants or marine environments.

Benefits

1. Precision Design: Ensures leak-proof connections and uniform fluid flow.
2. Versatile Material Options: Tailored to meet various application requirements.
3. Durability: Withstand high pressure and temperature conditions.
4. Easy Installation: Simplifies pipe network modifications and expansions.
5. Cost-Effective: Reducing maintenance and downtime.

Applications

JIS B2311 Tees are integral to industries including:

• Oil & Gas: For fluid transport in pipelines.
• Chemical Processing: Handling corrosive and high-temperature substances.
• Water Treatment Plants: Efficient distribution of water or chemicals.
• Power Plants: For handling steam and other high-pressure fluids.
• HVAC Systems: Facilitating distribution of refrigerants or air.
• Food & Beverage: For hygienic transfer of liquids.
