DIN 2642 loose tube flange is a standardized pipe connection component commonly used to connect pipes, valves, and other equipment. This flange type follows German Industrial Standard (DIN) 2642, hence the name DIN 2642 Loose Tube Flange. The following is a detailed introduction to this flange:
Structure and design:
DIN 2642 loose tube flange consists of the following main components:
External Ring (Disk): The external ring or disk is the main part of the flange that has a set of evenly spaced bolt holes and is typically used to connect to another flange or other part of the piping system.
Internal Orifice: The center portion of the flange has an inside diameter that matches the outside diameter of the pipe. This inner diameter is usually smaller than the diameter of the flange, so it can be used as a sleeve on the outside of the pipe.
Key features and uses:
DIN 2642 loose tube flanges have the following key features and uses:
Simple installation: Loose-thread flanges are very easy to install. They are often used to connect pipes and equipment, especially in applications that require frequent disassembly or maintenance.
Suitable for non-conventional pipe diameters: Due to the design of the internal opening of the flange, the DIN 2642 loose tube flange is suitable for connecting pipes with different pipe diameters. This makes it ideal for joining pipes of different sizes in ductwork.
Flexibility: The design of the loose-set flange allows for a degree of flexibility that can tolerate some slight misalignment of the pipe. This is useful for precise positioning during installation.
Low cost: This type of flange is generally more affordable than some other flange types, making it an option for pipe connections on a budget.
Application areas:
DIN 2642 loose tube flanges are typically used in the following applications:
Water Treatment: They are often used in the water treatment industry, including water and wastewater treatment systems, where frequent piping and maintenance are required.
Food and Beverage Industry: Loose tube flanges are also used in the food and beverage processing industry and are suitable for connecting food safe pipes and equipment.
Chemical and Pharmaceutical Industry: This flange type is also widely used in chemical production and pharmaceutical processes, especially where equipment needs to be frequently replaced or cleaned.
Overall, the DIN 2642 loose tube flange is a flexible, cost-effective and easy-to-install pipe joining component suitable for a variety of applications. They provide a reliable solution when connecting pipes and equipment, and are particularly suitable for piping systems that require frequent disassembly or maintenance.
