Industrial pipe and fittings are an important part of industrial modernization. They are widely used and are of great significance for realizing the automation of industrial production, improving production efficiency and ensuring production safety. With the continuous development of industrial technology, the design and manufacture of industrial pipes and fittings are also constantly innovating to meet various complex industrial production needs.
Industrial pipes are the general term for all tubular facilities within industrial enterprises (such as petroleum, chemical, light industry, pharmaceutical, mining and other industries), including process pipes, utility pipes and other auxiliary pipes. These pipes are used to transport gas, liquid or flammable, explosive and corrosive media. Industrial pipes can be divided into low-pressure, medium-pressure, high-pressure and ultra-high-pressure pipes according to the design pressure, water supply and drainage, hydrogen, heat, gas, fuel oil and other pipes according to the transport medium, and metal and non-metal pipes according to the material.
Fittings are the general term for parts used for connection, control, direction change, diversion, sealing and other functions in industrial pipeline systems. Pipe fittings include elbows, tees, crosses, reducers, pipe clamps, internal and external threaded joints, and unions. The material list of pipe fittings mainly includes style, connection form, pressure level, wall thickness level, material, specification standard, specification, etc.
Metal pipe :
Cast iron pipe : Suitable for buried water supply mains, gas mains, sewage pipes, etc., with good corrosion resistance, but low strength, high brittleness, not suitable for high pressure or toxic, explosive medium pipelines.
Carbon steel pipe : Generally not corrosion-resistant, but can withstand certain corrosion in specific occasions such as concentrated sulfuric acid and alkali solution, not suitable for chloride ion-containing occasions.
Stainless steel pipe : Such as austenitic stainless steel, with good corrosion resistance and heat resistance, suitable for oxidizing environment. 304 stainless steel is commonly used, with good corrosion resistance and intergranular corrosion resistance; 304L stainless steel low carbon version, suitable for applications that need to control carbon content to reduce intergranular corrosion; 321 stainless steel has better intergranular corrosion resistance and high temperature strength; 316 stainless steel adds Mo element, with better corrosion resistance, atmospheric corrosion resistance and high temperature strength.
Non-metallic pipes:
Plastic pipes: Such as PVC pipes and HDPE pipes, which have excellent corrosion resistance and light weight, are suitable for drainage and chemical fluid transportation, but have low strength, poor heat resistance, and are easy to age.
Plastic Industrial pipe and fittings, as an important infrastructure of modern industry, play a key role in ensuring the continuity and efficiency of production processes, reducing energy consumption and pollution. With the development of modern industrial technology, plastic industrial pipes are constantly innovating in materials, intelligence and other fields, and have become an important driving force for advanced manufacturing and industrial intelligence. Globally, the demand for plastic pipes continues to grow, especially in the construction, municipal, gas and other industries. In addition, compared with traditional metal pipes, plastic pipes have the advantages of energy saving and environmental protection, corrosion resistance, impact resistance, friction resistance, light weight and high strength, and long service life. They have gradually become the first choice in housing construction, underground drainage pipe systems, rainwater pipe systems and other fields.
Special materials:
1. Oil and gas industry: Industrial pipe and fittings play a key role in the oil and gas industry, used to transport fluid media such as oil and natural gas. These pipes need to withstand high pressure, high temperature and corrosion-resistant environments, so the performance requirements of the materials are extremely high.
2. Chemical industry: In the chemical industry, industrial pipes are used to transport raw materials, products and process media.
3. Power industry: In the power industry, industrial pipes are widely used in the construction of transmission lines and substations as efficient and durable conductive materials. Its stable conductivity and high mechanical strength can effectively reduce transmission losses and improve transmission efficiency.
4. Construction industry: In the construction industry, Industrial pipe and fittings also play an important role. For example, as the main connector of steel structure buildings, and in the water supply and drainage system, heating system and air conditioning system of buildings.
5. Transportation industry: Whether it is the guardrail of the highway, the rails of the railway, or the track beam of the subway, industrial pipes are indispensable. Its high strength, wear resistance, impact resistance and other characteristics meet the high requirements of transportation facilities for safety and stability.
6. Agricultural field: In the agricultural field, industrial pipes are also widely used. For example, the construction of greenhouses requires a large number of pipes as supporting structures. In addition, in farmland irrigation systems, pipes are also one of the important water pipes.
7. Environmental protection field: With the improvement of environmental awareness, the application of industrial pipes in the field of environmental protection is becoming more and more extensive. For example, the pipe system of sewage treatment plants and the flue gas emission pipes of garbage incineration plants all require a large number of industrial pipes.
