Threaded Flange

Easy installation: the installation of threaded flanges does not require welding or other complicated processes, and the connection can be realized only by screwing the threads together, which makes the installation faster and less costly.
Easy to dismantle: compared with welded flanges, threaded flanges are easier to dismantle and replace, which is very convenient for piping systems that require frequent replacement or maintenance.
Strong adaptability: threaded flanges are suitable for pipes and equipment made of various materials, including cast steel, forged steel, stainless steel, etc., which can meet the needs of different industrial fields.

Threaded flanges are widely used in petroleum, chemical, natural gas, water treatment and other fields, especially in low pressure and low temperature piping systems. In these fields, the piping systems need to withstand certain pressure and temperature, but usually do not need excessive strength requirements, so the threaded flange becomes an ideal connection device.

Thread matching: When installing a threaded flange, you must ensure that the threads on the flange match the threads on the pipe or equipment. This includes thread size, pitch, and thread type. Thread mismatch can result in poor thread quality or thread damage.
Sealing performance: Although the connection strength of a threaded flange is lower, its sealing performance is still very important. During installation, it is necessary to make sure that the sealing surface between the flange and the pipe or equipment is flat and clean, and apply an appropriate amount of sealant to improve the sealing performance.
Material selection: According to the use of different environments and media, it is necessary to choose the appropriate material to manufacture threaded flanges. For example, in corrosive media, it is necessary to choose stainless steel with better corrosion resistance.

Regular Inspection: Regularly inspect the threaded flange, including checking whether the threads are worn, damaged or loose, and whether the sealing surface is flat and clean. If problems are found, they should be dealt with in time.
Cleaning and maintenance: Clean the threaded flange and its connecting parts regularly to remove oil, dust and other impurities on the surface to maintain good connection status and sealing performance.
Anti-corrosion treatment: For threaded flanges exposed to corrosive environments, anticorrosion treatment is required, such as applying anticorrosion paint or electroplating, etc., to extend their service life.
