PVC (polyvinyl chloride) is a common plastic material, widely used in construction, industry, drainage, water supply and other fields. Especially in the pipeline system, PVC pipes have become the first choice for many pipeline materials due to their excellent corrosion resistance, light weight, good processing performance and low cost. 4 inch thin wall pvc pipe fittings, as a common specification in PVC pipeline systems, have important application value.
4 inch thin wall pvc pipe fittings specifications
4 inches refers to the outer diameter of the pipe fittings, which is approximately 100mm when converted to millimeters. Thin-wall PVC pipe fittings refer to a type of pipe fittings with relatively thin walls, which are usually used in pipeline systems with lower pressure and smaller loads. The specifications of 4 inch thin wall pvc pipe fittings involve different types of connection methods, sizes, pressure levels and other parameters.
1. Outer diameter and inner diameter
The outer diameter of 4-inch pipe fittings is generally 100mm, while the inner diameter varies depending on the thickness of the pipe wall. Thin-walled pipe fittings have a smaller wall thickness, usually between 3mm and 5mm. There may be certain differences between different standards and products produced by different manufacturers, so when selecting pipe fittings, it is necessary to determine the inner and outer diameters according to specific technical requirements.
2. Pressure rating
4 inch thin wall pvc pipe fittings usually have different pressure ratings, which are determined by the working pressure of the pipe system. Common pressure ratings include:
Low pressure rating: Suitable for systems with low working pressure, such as ordinary drainage pipes.
Medium pressure rating: Suitable for medium pressure environments such as water pumping systems and irrigation systems.
High pressure rating: Used in high pressure environments such as industrial water and chemical delivery. Different pressure ratings will affect the thickness of the pipe wall and the choice of materials.
3. Connection method
Bonded: The pipe fittings and pipes are bonded together with special PVC glue to form a sealed connection. This connection method is simple and reliable and suitable for most PVC pipe systems.
Threaded connection: suitable for occasions that require frequent disassembly and maintenance. Threaded connection has good operability.
Clamp connection: The pipe fittings are tightly connected to the pipeline through the clamp, which is common in occasions of quick installation and maintenance.
4. Material and quality standards
The material of 4 inch thin wall pvc pipe fittings is usually made of high-quality PVC raw materials, which has good corrosion resistance, pressure resistance and impact resistance. Common quality standards include:
China National Standard (GB/T)
American Standard (ASTM)
European Standard (EN)
Different quality standards will affect the performance and application scope of pipe fittings. Choosing the right standard is crucial to ensure the safe and stable operation of the pipeline system.
Application of 4 inch thin wall pvc pipe fittings
1. Building water supply and drainage system
In the water supply and drainage pipes of buildings, 4 inch thin wall pvc pipe fittings are usually used in the drainage systems of small and medium-sized buildings. Due to the corrosion resistance of PVC materials, it can effectively avoid water pollution, pipe rust and other problems. 4-inch pipes are suitable for drainage pipe systems of residential, shopping malls, office buildings and other buildings, and they carry small to medium-flow wastewater and rainwater.
2. Industrial pipe system
In industrial production, it is often used in low-pressure or medium-pressure pipe transportation systems. For example, low-corrosive liquid transportation in chemical plants, or water pipe systems in food processing plants. PVC pipes have good chemical resistance and are therefore widely used in industrial pipe systems.
3. Agricultural irrigation system
In the agricultural field, it is often used in irrigation systems. Especially in large-scale farmland irrigation, PVC pipes are an ideal choice for irrigation systems because of their corrosion resistance, lightness and easy installation. 4-inch pipes are suitable for connecting water pipes and water distribution pipes.
4. Cable protection pipe
In some occasions where cables need to be protected, 4 inch thin wall pvc pipe fittings can be used as cable protection pipes. This type of pipe can effectively prevent the cable from being damaged by external pressure, chemicals, etc. when buried underground, ensuring the normal operation of the cable.
5. Municipal drainage system
In the municipal drainage system, it is widely used for small drainage pipes, rainwater drainage pipes, etc. The installation and maintenance of this type of pipe fittings are relatively simple, and it has good durability and sealing, which can meet the requirements of the municipal drainage system.
6. Home and small commercial use
For home and small commercial buildings, it is often used to connect bathroom drainage, kitchen drainage, air conditioning drainage and other systems. Due to its corrosion resistance and rust-proof characteristics, PVC pipe fittings can effectively avoid pipe blockage and leakage problems during long-term use.
Advantages and Challenges
Advantages:
1. Strong corrosion resistance: PVC material is not easily corroded by chemicals and is suitable for a variety of corrosive environments.
2. Easy installation: Due to its light weight and various connection methods, the installation process of 4 inch thin wall pvc pipe fittings is relatively simple, saving construction time and manpower.
3. High durability: PVC pipes are not prone to aging, cracking and other problems during long-term use, which can ensure the long-term operation of the pipeline system.
4. Strong economy: Compared with other metal pipe materials, PVC pipe fittings are relatively cheap and cost-effective.
Challenges:
1. Poor temperature adaptability: PVC pipes have limited high temperature resistance, and long-term use in high temperature environments may cause the pipes to soften or deform.
2. Brittleness: Although PVC pipes perform well in daily use, they are prone to brittle cracking in low temperature environments, and antifreeze is required.
4 inch thin wall pvc pipe fittings are widely used in many fields such as building water supply and drainage, agricultural irrigation, industrial pipelines, and cable protection due to their excellent physical properties, convenient installation and economy. When choosing pipe fittings, in addition to considering technical parameters such as specifications, pressure levels, and connection methods, it is also necessary to select appropriate quality standards and pipe fitting types based on the actual application environment. With the development of science and technology, the production process of PVC pipe fittings is constantly being optimized, and its application prospects will become more and more extensive.
