Pressure Rating: PN160 | Temperature Range: -29°C to 425°C | Ideal for Pipeline Systems
Product Overview
The Welding Neck Flange is a high-quality forged steel component designed for demanding industrial applications. Manufactured from premium materials, this flange delivers exceptional strength, durability, and resistance to harsh environments, making it ideal for reliable, long-lasting piping system connections.
Crafted from steel number 1.8845 (P245GH), this flange exhibits excellent mechanical properties and withstands high pressure and temperature conditions. The weld-neck collar design ensures smooth stress transition between flange and pipe, reducing stress concentration and enhancing joint integrity.
The material used is China Grade X2CrNiMoN22-5-3, a high-grade stainless steel known for exceptional corrosion resistance in acidic and chloride-containing environments. This provides outstanding resistance to pitting and crevice corrosion, ensuring longer service life and reduced maintenance costs.
Packaging: Each flange is securely packed in wooden cases for protection against mechanical impacts, moisture, and contamination during transportation and storage.
