DIN / EN loose flanges
The offered DIN / EN loose flange (lap-joint Flange) is a two-piece flange of stainless steel that feels like a welding neck flange and is welded with the tubes as well as a loose slip-on flange.
The DIN / EN loose flange's first part is called a' Stub-end' and is molded like piece of pipe with a tight strap on one end and a butt weld end on the other end called the core.
The tight shoulder sizes are like the flange's raised face, the stub-end's top weld end is like the welding end of the flange which matches the conecction pipe's diameter and length. The hub's back face has a rounded transition that connects the hub to the collar.
The DIN / EN stainless Loose Flange's other component is the back flange. Backing flange dimensions are the same as other common flanges (O.D.,PCD, Bolt hole, etc.) but it does not have a raised face (the stub end has a raised face).
On one side of the lap joint flange, the backside, has a slight shoulder cut in the center or pipe hole. The front panel has a plain plate and an outer filet to match the "Stub-end" part filet in the middle drawer.
Before the strap is attached to the tube or suitable for attachment, the flange portion of the Lap-joint flange installation is slid on to the stub-end. In no manner is the flange itself welded or corrected. Spinning is safe for the right alies are used a lot in the low pressure piping systems

What are the main advantages of using DIN / EN loose flanges in piping systems?
The main advantages of using DIN / EN loose flanges include their flexibility in assembly and disassembly, which allows for easier maintenance and repair of piping systems. Additionally, they reduce the risk of leakage due to their design, as they provide a secure connection when used with lap-joint fittings. Furthermore, stainless steel loose flanges, such as Stainless loose flanges EN1092-1, PN6, are highly resistant to corrosion, making them ideal for use in aggressive environments.
How do you determine the appropriate pressure rating for DIN / EN loose flanges?
The appropriate pressure rating for DIN / EN loose flanges is determined based on the application and the operating conditions of the system. It is essential to consider factors such as the operating temperature, fluid type, and the required safety margins. Flanges come with various pressure ratings; for instance, you can find options like Stainless loose flanges EN1092-1, PN10 and Stainless loose flanges EN1092-1, PN16, which cater to different pressure requirements.
What materials are commonly used for DIN / EN loose flanges and why are they selected?
Common materials for DIN / EN loose flanges include stainless steel, carbon steel, and alloy steels. Stainless steel is frequently used due to its excellent corrosion resistance, especially in harsh environments. For example, Stainless loose flanges EN1092-1, PN25 are designed for high-pressure applications, while Stainless loose flanges EN1092-1, PN40 can handle even greater pressures, ensuring durability and performance in demanding conditions.
