Weld Neck Flanges
Weld Neck Flanges are one of the most common types of flanges used in high-pressure applications. The design features a long tapered hub that provides excellent reinforcement at the junction where the flange is welded to the pipe. This flange type is ideal for applications involving high stress due to the seamless transition between the flange and the pipe, which helps to reduce stress concentration. Industries such as oil and gas, petrochemicals, and nuclear energy heavily rely on Weld Neck Flanges for their durability and ability to withstand extreme pressures and temperatures.The welding process involved in attaching Weld Neck Flanges ensures a permanent, leak-proof connection, making them suitable for critical applications where safety is paramount. However, the installation of Weld Neck Flanges requires skilled labor and specialized equipment, which can increase overall costs. Despite these challenges, the benefits they offer in terms of reliability and longevity make them a preferred choice for many industrial applications.

5. Can we visit your factory?
--Warmly welcome. Once we have your schedule, we will arrange the professional sales team to follow up your case.
6.Compare with the stainless steel vs galvanized steel ?
--The protective layer on galvanized is not self-healing like the passive layer on stainless steel. This means that over extended periods, galvanized parts are generally less durable than stainless ones.When compared at similar thicknesses and forms, stainless steel is always stronger than galvanized steel.Since galvanization does not impact the tensile strength of the underlying metal, you could reasonably expect galvanized steels made from various steel grades to have comparable tensile strength compared to the original steel.In most cases, stainless steel and galvanized steel will have a very similar weight. Galvanized steel offers the same malleability as the underlying steel used. This means that in most cases, it will be more malleable than comparably shaped stainless steel forms.
