Classification of pressure pipeline
As an indispensable infrastructure in industrial and civil fields, the classification standard of pressure pipeline is very important to ensure the safe operation, reasonable design and construction of pipeline. As a professional steel pipe company, we are well aware of the importance of classification standards for pressure pipes. Here are some common classification standards for pressure pipes:
Classification by pressure grade
Low pressure pipeline: usually refers to the pressure pipeline with design pressure less than or equal to 1.6MPa. This kind of pipeline is generally used in some occasions with low pressure requirements, such as some branch pipes in urban water supply network and auxiliary fluid transportation in general industrial plants. The low-pressure pipeline produced by us has good corrosion resistance and certain compression resistance, which can meet the use requirements under normal working conditions.
Medium pressure pipeline: pressure pipeline with design pressure above 1.6MPa to 10MPa belongs to medium pressure pipeline. Medium-pressure pipelines are often used in urban gas transportation, some pipelines of central heating system and medium-pressure fluid transportation in some industrial production, such as the transmission pipelines of some media in chemical enterprises. Our medium-pressure pipeline products adopt high-quality steel and advanced manufacturing technology to ensure the safe and reliable operation of the pipeline in the medium-pressure environment.
High-pressure pipeline: the pressure pipeline with design pressure above 10MPa to 100MPa is a high-pressure pipeline. High-pressure pipelines are mainly used in places with high pressure requirements, such as hydrogenation process pipelines and high-pressure steam transportation pipelines in petrochemical industry. In the production process of high-pressure pipeline, we strictly control the quality, adopt high-strength steel and precise processing technology to ensure that the pipeline can withstand various stresses brought by high pressure.
Ultra-high pressure pipeline: pressure pipeline with design pressure greater than 100MPa belongs to ultra-high pressure pipeline. Ultra-high pressure pipeline is generally used in some special industrial fields, such as pipeline system of ultra-high pressure water cutting equipment and material conveying pipeline of some ultra-high pressure chemical reaction devices. Ultra-high pressure pipeline requires extremely high materials, manufacturing technology and quality inspection. With advanced technology and rich experience, we provide high-quality ultra-high pressure pipeline products for specific customers.
Classification by conveying medium
Gas pipeline: mainly used for transporting combustible gases such as natural gas and coal gas. Gas pipelines require extremely high safety. The gas pipelines we produce are made of steel with good corrosion resistance and crack growth resistance, and are equipped with advanced anti-corrosion and sealing technologies to ensure the safety of gas during transportation.
Thermal pipeline: used to transport thermal energy media such as hot water or steam. Thermal pipelines need to have good thermal insulation performance and thermal stress resistance. We will provide customers with suitable pipeline materials and thermal insulation schemes according to different thermal transmission requirements, so as to reduce heat energy loss and improve heating efficiency.
Industrial pipeline: it covers pipelines for conveying different media in various industrial production, such as crude oil, chemical raw materials and refined oil in petrochemical industry, and pipelines for conveying various process media in pharmaceutical and food industries. The medium characteristics of industrial pipelines are complex and diverse. We will choose appropriate materials and manufacturing processes according to the characteristics of corrosiveness, toxicity, flammability and explosiveness of different media to ensure the safe operation of pipelines.
Water supply and drainage pipelines: including urban water supply pipelines and drainage pipelines. Water supply pipeline requires pollution-free water quality and good corrosion resistance; Drainage pipes need to have certain anti-scouring and anti-sewage corrosion ability. According to the characteristics of water supply and drainage pipelines, we provide corresponding products and solutions to ensure the normal operation of urban water supply and drainage systems.
Classification by pipeline material
Metal pipes: including carbon steel pipes, stainless steel pipes and alloy steel pipes. Metal pipeline has the advantages of high strength, good pressure resistance and long service life, and is widely used in various pressure pipeline systems. The metal pipes we produce are made of high-quality steel raw materials, and the quality and performance of the pipes meet the requirements of high standards through advanced rolling and welding processes.
Non-metallic pipes: plastic pipes, glass steel pipes and ceramic pipes are common. Non-metallic pipes have the characteristics of corrosion resistance, wear resistance and good insulation performance, and are suitable for some occasions with high corrosion resistance or special insulation requirements, such as acid medium transportation in chemical industry and pure water transportation in electronic industry. We also provide various types of nonmetallic pressure pipeline products to meet the needs of different customers.
