A Lap Joint Flange with a Flat Welding Ring consists of two parts: a loose flange ring and a flat welding ring.
Components
Loose Flange Ring: A ring-shaped component with a hub that can rotate freely, making it easy to align the bolt holes during installation.
Flat Welding Ring: A sealing ring that is welded to the end of the pipe. The seal is created when this ring is pressed against the mating flange by the bolts.
Specifications
Typical Materials: Carbon steel (e.g., Q235) and stainless steel (304/316).
Common Pressure Ratings: PN6 to PN16.
Installation and advantages
The flat welding ring is welded to the pipe end, and the loose flange ring is used for alignment during bolt tightening. This design helps reduce thermal deformation as the main flange body is not welded. It is advantageous in systems needing frequent disassembly.

Product Features
1. Split-body design:
Consists of a flat welding ring (made of the same material as the pipe) and a loose flange body (typically carbon steel), with sealing achieved by bolt tightening.
2. Non-direct welding:
The flange body is not directly welded to the pipe. It is connected to the pipe only via the flat welding ring, which reduces the corrosion risk to the flange body.
3. Rotatable adjustment:
The loose flange body can rotate freely, which facilitates the alignment of bolt holes and simplifies the installation process.
4. Convenient maintenance:
During disassembly, only the bolts need to be loosened, without cutting the pipe, making it suitable for applications requiring frequent inspection and repair.
Product Advantages
Manufacturing Process
Socket Weld Flange are manufactured in strict compliance with relevant standards and specifications.
Production Process
From the selection of raw materials, through cutting, forming, welding, and heat treatment, to the final inspection, every step is subject to precise control and strict quality testing.
Equipment and Team
With advanced production equipment and a professional technical team, we ensure that every flange product has excellent dimensional accuracy and surface quality.
Convenient construction
Because the flange body can rotate during installation, there is no difficulty with misaligned bolt holes when inserting bolts, which greatly improves the convenience of installation. This feature is particularly useful in piping systems that require frequent disassembly or potential equipment replacement in the future.
Wide applicability
This type of flange is particularly suitable for:
Stainless and acid-resistant steel pipes
Non-ferrous metal pipes (such as copper and aluminum)
Plastic pipes, FRP pipes, and other materials that are difficult to weld or require greater strength for the pipeline connection
