Coupling pipe types mainly include welding connection pipe, flange connection pipe, ferrule connection pipe, threaded connection pipe, pipe cap connection pipe, etc. These different types of connection pipes are suitable for different pipeline systems and engineering requirements according to their different structures and functions, ensuring the safe and stable operation of the pipeline system.
Commonly used coupling pipe types
1. Welding connection pipe: Two pipes or pipes and pipe fittings are connected together by hot melt welding process, which has the characteristics of firm connection, good sealing, corrosion resistance, and strong pressure bearing capacity.
2. Flange connection pipe: Two pipes or pipes and pipes are connected together by flanges, which is suitable for pipeline systems that require frequent disassembly and cleaning. The advantages of flange connection pipes are easy installation and maintenance, and different flanges can be replaced as needed.
3. Ferrule connection pipe: Two pipes or pipes and pipes are connected together by ferrules, which is suitable for occasions that need frequent disassembly during on-site installation. The advantages of ferrule connection pipes are easy installation, quick disassembly, and certain vibration absorption and compensation capabilities.
4. Threaded connection pipe: Two pipes or pipes are connected together through threads, which is suitable for small-diameter pipe systems. The advantages of threaded connection pipes are easy installation, easy disassembly and low cost.
5. Cap connection pipe: Pipe fittings used to seal the end of the pipe can play the role of sealing the end of the pipe and have good dust and waterproof effects. Common cap connection pipes include welded pipe caps, threaded pipe caps, etc.
Material selection
1. There are many types of materials for connection pipes, including steel, cast iron, plastic, glass, copper, alloy, etc. Each material has its unique advantages and applicable scenarios, and the use environment and requirements need to be considered when choosing.
2. Steel connection pipe, usually made of carbon steel, stainless steel or alloy steel. Carbon steel connection pipes have the characteristics of high strength, corrosion resistance, high temperature resistance, etc., and are suitable for general industrial environments. Stainless steel connection pipes have good corrosion resistance and are particularly suitable for industries with high hygiene requirements, such as medicine and food processing. Alloy steel connection pipes are suitable for use in high temperature and high pressure environments.
3. Cast iron connecting pipe, made of cast iron material, is usually used in drainage systems in construction projects. Cast iron connecting pipe has high strength and rigidity, can withstand pressure and impact, and has good corrosion resistance. In addition, it also has good sound insulation and heat insulation, suitable for occasions with high noise and temperature requirements.
4. Plastic connecting pipe, mainly including PVC Fittings, PP Fittings, PE Fittings, etc. Plastic connecting pipe has the characteristics of light weight, easy installation, and good insulation performance. PVC connecting pipe fittings have good corrosion resistance and water resistance, suitable for drainage and water supply systems. PP connecting pipe has stronger corrosion resistance and is suitable for special chemical medium transportation. PE connecting pipe has high pressure resistance and corrosion resistance, suitable for conveying gas and liquid.
5. Glass connecting pipe, usually made of borosilicate glass, has good chemical stability and high temperature resistance. Glass connecting pipe has high transparency and will not cause any pollution to the medium. It is suitable for chemical laboratories, medicine and other industries.
Copper connecting pipe, usually made of oxygen-free copper, brass and other materials. Copper connecting pipes have good thermal conductivity and electrical conductivity, as well as good corrosion resistance, and are widely used in water supply, heating, air conditioning and other systems.
6. Alloy connecting pipes, composed of alloys of different metal raw materials to improve the corrosion resistance and strength of the connecting pipes. Alloy connecting pipes are usually used in special industrial environments, such as petroleum, chemical and other fields.
