WELDING NECK FLANGE
Features:
Pipe flanges, their gaskets, and fasteners are collectively referred to as flange joints. Flange joints are a type of component that is widely used and involves a wide range of aspects in engineering design. It is an essential component in piping design, pipe fittings, and valves, as well as an essential component in equipment and equipment components such as manholes, sight glasses, and liquid level gauges. In addition, flange joints are often used in other professions such as industrial furnaces, thermal engineering, water supply and drainage, heating and ventilation, and automation.

Product Details
Product material: SS304, 304L, 316, 316L, 2205, 904L and special materials are customized.
Product caliber: DN15mm-DN2000mm
The nominal pressure is around PN1.0MPa~PN25.0MPa
The executive standards include GB series , JB series , HG series, ASME B16.5, BS4504, DIN , JIS,etc.
Due to the transition structure of the cone neck and the butt welding connection, the strength and rigidity of the flange are strengthened, and the sealing performance is better than that of the fat welded flange. It is suitable for occasions with high pressure, high temperature or high sealing requirements.
Application
The sealing surface forms of neck welded flanges include: raised face (RF), concave face (FM), raised face (M), tenon face (T), groove face (G), and full face (FF).
Advantages: The connection is not easily deformed, the sealing effect is good, and it is widely used. It is suitable for pipelines with significant temperature or pressure fluctuations, as well as high-temperature, high-pressure, and low-temperature pipelines. It is also used for transporting expensive media, flammable and explosive media, and toxic gases in pipelines.
Neck welded flanges are mainly used in situations where the working conditions are relatively harsh, such as situations where the flange is subjected to significant stress or repeated stress changes due to thermal expansion or other loads in pipelines, pipelines with significant fluctuations in pressure and temperature, or pipelines with high, high, and sub zero temperatures. The neck welded flange is not easy to deform, has good sealing, and is widely used.
Packing & Delivery
We use wooden boxes and pallets for packaging, and the valves will be wrapped in bubble film plastic bags to ensure maximum product safety. We support sea transportation, and products can also be shipped to any port you specify.
