What Is 304 20592PL Flange DN25*PN6? A Complete Introduction

In modern fluid and gas transmission systems, the flange connection plays a decisive role in maintaining sealing performance and pipeline safety. Among the many available options, the 304 20592PL Flange DN25*PN6 is one of the most commonly used models in the Plate Welding Flange category. It is favored for its durability, ease of installation, and compliance with GB/T 20592 standards.

For distributors, EPC contractors, and engineers, the decision does not stop at technical parameters alone. Sourcing directly from a China manufacturer with bulk supply capacity not only guarantees product quality but also secures pricing stability and long-term availability.

Understanding 304 20592PL Flange DN25*PN6

·304 Stainless Steel: Manufactured using 304 stainless steel, the flange offers a high level of corrosion resistance against moisture and mild chemical exposure, making it reliable in a wide range of environments.

·20592PL Standard: The PL refers to Plate Welding Flange defined under GB/T 20592. This standard governs dimensions, tolerance, and technical requirements.

·DN25 Diameter: Indicates a nominal bore size of 25 mm, suitable for small-to-medium pipelines.

·PN6 Pressure Rating: Designed to withstand up to 6 bar, this makes the flange suitable for low-pressure service conditions such as municipal water, HVAC, and light-duty chemical applications.

This combination of materials, dimensions, and pressure capacity makes the 304 20592PL DN25*PN6 a well-rounded and cost-efficient solution for low-pressure pipeline systems.

Key Advantages of Plate Welding Flange

1. Reliable Welded Connection

By welding directly to the pipe, Plate Welding Flange ensures strong mechanical integrity and minimizes the risk of leakage.

2. Simple Construction & Easy Handling

Its flat plate structure simplifies both fabrication and maintenance, saving time and labor costs during installation.

3. Cost-Effective Option

Compared to other flange types, Plate Welding Flange is economical, making it ideal for projects requiring a large number of connections.

4. Wide-Ranging Applications

Whether in municipal water systems, HVAC installations, or food-grade processing pipelines, its versatility supports a broad scope of use cases.

Selection Considerations for 304 20592PL DN25*PN6

1.Material Certification
Confirm that the product is made of certified 304 stainless steel to guarantee corrosion resistance and mechanical reliability.

2.Dimensional Accuracy
Ensure compliance with GB/T 20592 for seamless compatibility with pipes, bolts, and sealing gaskets.

3.Pressure Rating Validation
PN6 is suitable for low-pressure service; for higher demands, select Plate Welding Flanges with greater PN ratings.

4.Surface Quality
A smooth sealing surface ensures tight gasket contact and reduces leakage risk.

5.Supplier Reliability
Choosing a China factory with bulk supply capability guarantees on-time delivery, consistent product quality, and cost savings.
