Threaded flanges connection and socket welding flanges connection are two commonly used pipeline connection methods.
A threaded flange is a connection flange by opening threaded holes on the flange and pipeline, and then connecting the flange and pipeline through threads. It is usually suitable for low pressure, small diameter pipeline connections, such as frequently used in household water and air conditioning pipelines.
Socket welding flange is a connection flange that involves machining the flange at the interface between the flange and the pipeline, and then connecting the flange and the pipeline through welding. It is usually suitable for high-pressure, large-diameter pipeline connections, such as in industrial fields such as petroleum, chemical, and power.
There are some similarities between them:
1. Reliability: Whether it is threaded flanges connection or socket welded flanges connection, they are reliable pipeline connection methods. They can ensure the firmness and stability of pipeline connections.
2. Widely used: Threaded flanges and socket welding flanges are commonly used pipeline connection methods and are widely used in industries, construction, water conservancy and other fields.
3. Easy maintenance: Both threaded flanges and socket welding flanges can be easily disassembled and replaced, making it convenient for pipeline maintenance and upkeep.
4. Standardization: Both threaded flanges and socket welding flanges have standardized specifications and requirements, such as the International Organization for Standardization (ISO) and the American Standards Institute (ANSI), making them easier to use and exchange.
5. Variety of material choices: Whether it is threaded flanges or socket welded flanges, their manufacturing materials are relatively diverse, and appropriate materials can be selected based on specific usage environments and requirements. Common materials include carbon steel, stainless steel, cast iron, etc.
But there are the following differences between them:
1. Different connection methods: threaded flanges connect pipes and flanges through threads, while socket welded flanges connect pipes and flanges through welding.
2. Different application ranges: threaded flanges are usually used for low pressure and small diameter pipeline connections, while socket welded flanges are suitable for high-pressure and large diameter pipeline connections.
3. Different installation methods: The installation of threaded flanges is relatively simple, just align and tighten the threads. The installation of socket welding flanges requires welding, which requires higher technical requirements and operational skills.
4. Different sealing performance: Due to the fact that socket welding flanges can undergo heat treatment during welding, better sealing performance can be achieved. However, threaded flanges may pose a risk of leakage.
5. Different costs: Due to the higher technical requirements and operational skills required for the installation of socket welding flanges, their costs are relatively high. Threaded flanges are relatively cheaper.
