Wide range universal coupling DN250 PN16 flange adapter stainless steel compensator dresser expansion bolt joint
Product Introduction
Flange adapters are designed for use as pipes with wide tolerance systems. It is suitable for most standard piping materials, thus significantly reducing the number of special flange adapters that need to be stored for maintenance purposes. When connecting PE pipes, it is important to insert the tubes into the PE pipes.
Product application field
1. Petroleum and chemical industry: In the petroleum and chemical industry, flange adapters are widely used in various pipeline systems for transporting oil, chemicals and other media.
2. Papermaking and food industry: In the papermaking and food industry, the flange adapter is generally made of stainless steel, which is used to convey pulp, food and other media.
3. Water supply and fire protection industry: In the field of water supply and fire protection, flange adapters can be used for various pipe connections and fire protection systems.
4. Electric power, metallurgy, shipbuilding, aerospace and other industries: Flange adapters are also widely used in these industries to connect different types of pipelines to ensure the connectivity and normal operation of the system.

Scenarios and precautions for the use and selection of flange adapters
1. Different specifications: When the flange specifications are inconsistent, such as size, thickness or other physical characteristics do not match, the flange adapter can solve these problems.
2. Special applications: In some special application scenarios, such as high temperature environment, chemical corrosion environment, etc., special design flange adapters may be required to adapt to these conditions.
3. Repair and transformation: In the process of repairing or renovating the old system, you may encounter the need to connect the old and new flanges, and you also need to use a flange adapter.
