Key Specifications of the Reducing Tees in the Order
The EN 10253-2 standard outlines the requirements for butt-weld pipe fittings, and the reducing tees in this order adhere strictly to these standards. The following are the specific reducing tees ordered by our Singapore customer:
1. REDUCING TEE SMLS CS DN25 X DN15
- Thickness: 3.2 MM
- Material: 1.0352 (P245GH)
- Standard: EN 10253-2
- This reducing tee connects a DN25 (1-inch) pipe to a DN15 (½-inch) pipe, with a thickness of 3.2mm. The material P245GH is a carbon steel commonly used for general-purpose applications, offering strength and corrosion resistance.
2. REDUCING TEE SMLS CS DN50 X DN25
- Thickness: 5.0 MM x 3.6 MM
- Material: 1.0426 (P280GH)
- Standard: EN 10253-2
- This reducing tee connects a DN50 (2-inch) pipe to a DN25 (1-inch) pipe. The thickness varies between 5.0mm on the larger end and 3.6mm on the smaller end, providing extra strength where it is needed for high-pressure applications. The material P280GH is a higher-grade carbon steel, ideal for medium to high-pressure environments.
3.REDUCING TEE SMLS CS DN25 X DN20
- Thickness: 3.2 MM x 3.2 MM
- Material: 1.0426 (P280GH)
- Standard: EN 10253-2
- This reducing tee connects a DN25 (1-inch) pipe to a DN20 (¾-inch) pipe, with uniform wall thickness of 3.2mm. It is manufactured using P280GH carbon steel, ensuring enhanced strength and durability for reliable operation in medium-pressure applications.
Seamless Construction: Strength and Reliability
The seamless construction of the EN 10253-2 reducing tees is a significant advantage in industrial piping systems. Seamless fittings are manufactured from a single piece of material, which eliminates the potential weaknesses created by welded seams. This results in:
- Higher strength: Seamless construction ensures uniformity in wall thickness, offering better resistance to pressure.
- Improved durability: Seamless tees are less prone to cracks or failures, making them more reliable in high-pressure environments.
- Corrosion resistance: The seamless design reduces the risk of localized corrosion, which can sometimes develop along weld seams.
The butt-weld (BW) connection design of these reducing tees also ensures that the fittings provide a secure and leak-proof connection, making them ideal for pipelines that transport high-pressure fluids or gases.
