About this product
Product information from the supplier.
The Socket Weld Flange is a precision-engineered piping component designed for secure, leak-proof connections in high-pressure industrial systems. Featuring a specialized socket that receives the pipeline, this flange is joined via an annular fillet weld, creating a robust structural bond that ensures maximum stability and reliability under demanding operational conditions.
Engineered to meet rigorous global standards, our socket weld flanges are ideal for small to medium-diameter piping (typically DN50 and below). By combining a compact design with superior sealing performance, they provide an efficient solution for transporting hazardous, flammable, or corrosive media across the petrochemical, power generation, and shipbuilding industries.

Key Advantages
High Connection Strength
The integral welded joint provides exceptional resistance to high pressure and mechanical vibration, ensuring long-term stability.
Superior Sealing
Tight welded seals effectively prevent leaks, making them safe for toxic, flammable, or explosive industrial media.
Compact Design
A shorter profile compared to weld neck flanges allows for easier installation in confined spaces and tighter layouts.
Cost-Effectiveness
Reduced processing costs and simpler installation for small-bore pipelines significantly lower overall project expenses.
Wide Versatility
Compatible with various materials and pressure classes to meet diverse temperature and chemical environment needs.
Standard Compliance
Fully compliant with ASME B16.5, ensuring seamless integration with international piping components.

Frequently Asked Questions
The primary materials include Carbon Steel (A105, A350 LF2) for general use, Stainless Steel (304, 316) for corrosion resistance, and Alloy Steel (F11, F22, F91) for high-temperature and high-pressure environments.
Socket weld flanges are preferred for small to medium-diameter pipelines (typically DN50 and below) where space is limited and lower installation costs are desired without compromising seal integrity.
Common pressure ratings available are Class 150, 300, 600, 900, 1500, and 2500, with higher ratings offering increased thickness and bolt strength for high-pressure systems.
Yes, provided that Stainless Steel (such as 316L) is selected. These materials offer excellent resistance to oxidation and corrosion from acids, alkalis, and salt solutions.
The most common sealing faces include Raised Face (RF), Male-Female Face (MFM), and Tongue-Groove Face (TG), selectable based on the specific operating pressure and media requirements.
Yes, the fillet weld formed between the pipe and the socket provides high connection strength and excellent resistance to pressure fluctuations and mechanical vibrations.
