Stainless Steel Flange Forged Slip Weld Neck Blind Type Titanium Machining Services

 

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.
 

Socket Welding Flanges
Socket Weld flanges were initially developed for use on small-size high pressure piping. Their static strength is eoual to Slip On flanges, but their fatigue strength 50% greater than double-welded Sip On flanges. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.
The purpose for the bottoming clearance in a Socket Weld is usually to reduce the residual stress at the root of the weld that could occur during solidification of the weld metal. The image shows you the X measure for the expansion gap. The disadvantage of this flange is right the gap, that must be made. By corrosive products, and mainly in stainless steel pipe systems, the crack between pipe and flange can give corrosion problems.
