Hard Pipe

Introduction to Pipe Hard Pipe Products
1、 General Overview
Rigid Tube is a kind of pipe material commonly used in industry and construction field, with high strength and rigidity, which can bear the impact of large internal and external pressure and external environment. Hard pipes are generally made of metal, plastic or composite materials, widely used in liquid and gas transmission, mechanical equipment connection, building heating and cooling systems and other fields. Rigid tubing offers greater stability and durability than hoses, and is suitable for environments where fluid delivery, pressure, and corrosion resistance are critical.
The hard pipe can not only ensure that the fluid maintains a good flow state for a long time, but also effectively protect the internal fluid from external pollution or damage. Based on different application requirements, hard pipes can be provided with various sizes, materials and surface treatment methods to meet different working environment and functional requirements.
2、 Types of hard pipes
Hard pipes can be divided into various types according to different materials, and each type of hard pipe has different advantages in specific application scenarios. Common hard pipe materials include:
Metal Hard Piping:
Steel pipe: steel pipe is the most common one among hard pipes, with extremely high strength and corrosion resistance. Steel pipes are widely used in petroleum, natural gas, building, machinery and other fields, especially in the occasions requiring high pressure resistance and impact resistance.
Stainless steel pipe: stainless steel pipe has more corrosion resistance than ordinary steel pipe, and is applicable to food processing, medicine, chemical industry and other environment with high requirements for cleaning and sanitation. Stainless steel pipes are also suitable for high temperature, wet and harsh environments due to their corrosion and oxidation resistance.
Aluminum alloy tube: Aluminum alloy tube has the advantages of light weight, corrosion resistance and oxidation resistance, and is commonly used for connection of aviation, transportation tools and electronic equipment. The ease of processing and strong fatigue resistance make it widely used in engineering.
Plastic hard pipe:
PVC hard pipe: PVC hard pipe has strong chemical resistance and is widely used in water pipes, cable protection pipes, agricultural irrigation pipes, etc. PVC pipe is light, corrosion resistant and easy to install, and is one of the commonly used pipes in the building and water treatment industry.
PE hard pipe: PE hard pipe is a kind of pipe with high toughness, which is applicable to municipal water supply, natural gas transmission, sewage treatment, etc. It has good low temperature resistance and corrosion resistance, and is suitable for use under various severe conditions.
PP hard pipe: Polypropylene (PP) hard pipe has good heat resistance and chemical resistance, and is suitable for chemical transmission, hot water pipeline and other occasions with special requirements on temperature and corrosion.
Composite hard pipe:
Composite hard pipes are manufactured from a variety of different materials through composite technology, usually combining the advantages of metal and plastic, which can provide better corrosion resistance, strength and flexibility. Common composite hard pipes include steel-plastic composite pipes, glass steel pipes, etc.
3、 Features and advantages of hard pipe
As an important pipeline product, hard pipe has many advantages, making it play an important role in various industrial and engineering fields. Its key features and advantages include:
High strength and rigidity: the hard pipe has high strength and rigidity and can bear large external pressure and internal fluid pressure to ensure stability and safety in long-term use. This enables the hard pipe to effectively prevent deformation, fracture and other problems of the pipeline when conveying liquids, gases and other media.
Corrosion resistance and weather resistance: hard pipes have different corrosion resistance according to different materials. Hard metal pipes (such as stainless steel pipes) can be used in highly corrosive environment. Hard plastic pipes (such as PVC and PE pipes) have good acid and alkali resistance and chemical corrosion resistance, and are suitable for conveying special liquids such as chemicals or sewage.
Long-term durability: due to the durability and anti-aging ability of hard pipes, they can maintain good use performance for a long time, reducing the frequency of pipe replacement and maintenance costs.
Good fluid transmission capacity: the inner wall of the hard pipe is smooth and the fluid friction resistance is small, which is conducive to the fast transmission and control of fluid. Especially in the transportation process of liquid and gas, the hard pipe can effectively maintain the flow and reduce energy waste.
Fire and explosion prevention performance: some types of hard pipes, especially metal pipes and composite pipes, can provide good fire and explosion prevention characteristics and are suitable for fluid transportation in hazardous environment, such as pipeline system in oil and gas industry.
Diversified application fields: a wide range of hard pipes. From architecture, transportation, chemical industry, energy industry to agriculture, home, medical and other industries, hard pipes can meet specific functional requirements while providing reliable connection.
4、 Application field of hard pipe
Hard pipe is widely used in various industries due to its reliability and diversity. The following are some common application fields of hard pipe:
Construction industry: Hard pipes are widely used in the construction industry, including wire and cable protection pipes, water supply pipes, drainage systems, etc. PVC and PE hard pipes are commonly used in residential and commercial buildings due to their corrosion resistance and easy installation.
Oil and gas: hard pipes are especially important in the transportation of oil and gas. Steel pipes, stainless steel pipes and composite pipes have excellent durability and safety under these high pressure and high corrosion environments, which can effectively guarantee the safe transmission of energy.
Connection of machinery and equipment: in industrial machinery equipment, hard pipes are commonly used in hydraulic system, cooling system, gas transmission pipeline, etc. Hard metal pipes, especially stainless steel pipes and aluminum alloy pipes, are widely used in aviation, automobile, machinery manufacturing and other fields due to their high strength and corrosion resistance.
Chemical industry: in the chemical industry, many chemicals are highly corrosive to pipe materials, so PVC, PE and other corrosion-resistant hard pipes are widely used in the transportation of chemicals. They effectively prevent chemical damage to the pipeline.
Food and Pharmaceutical Industry: Stainless steel rigid pipes are widely used in food processing and pharmaceutical industries because they do not react with the conveyed substances, comply with hygiene standards, and are easy to clean to ensure hygiene requirements during production.
5、 Summary of Summary
As an important pipeline material, hard pipe has become an indispensable infrastructure component in many industries due to its high strength, corrosion resistance, reliability and adaptability. Hard pipes play a key role in building, transportation, energy, chemical industry, medicine and other fields. With the continuous progress of science and technology, the material, process and application fields of hard pipes will also be expanded. In more fields in the future, hard pipes will still be the ideal choice for connecting and protecting fluid transmission systems.
