PVC (polyvinyl chloride) pipes have become important pipe materials in the fields of construction, drainage, water supply, industry, etc. due to their good corrosion resistance, convenient installation, and economic advantages. 75mm pvc pipe fittings are common medium-sized pipe fittings, which are widely used in various water supply, drainage, line protection and other systems. This article will introduce the specifications, imperial size comparison and wide application of 75mm pvc pipe fittings in detail.
Specifications of 75mm PVC pipe fittings
75mm PVC pipe fittings are usually used in medium-flow pipe systems and have good pressure-bearing performance and corrosion resistance. According to different standards and requirements, 75mm PVC pipe fittings include various types of connectors. Common pipe fitting specifications mainly include pipes, elbows, tees, reducers, joints, flanges, etc. These pipe fittings can be used in different pipe systems to ensure the smooth delivery of water, air or other fluids.
1. Outer diameter and inner diameter
75mm PVC pipe fittings usually refer to pipes with an outer diameter of 75mm and an inner diameter of approximately 63mm. The specific inner diameter value will vary depending on the thickness of the pipe wall. The common pipe wall thickness is 2-3mm, depending on the working pressure level of the pipeline (such as PN4, PN6, PN10, etc.).
2. Pipe fitting types
Straight pipe: mainly used for straight laying, connecting two sections of pipes.
Elbow: usually elbows with angles of 45°, 90°, etc., used to change the direction of the pipeline.
Tee: used to connect three pipes together, common ones are straight tees and reducing tees.
Joint: used to connect two sections of pipes of the same or different specifications.
Reducing pipe: used to connect pipes of different diameters, usually used for pipe transition.
Flange: used to connect pipes and equipment with bolts, commonly used in pipe systems that need to be disassembled or repaired.
Pipe cap: used to close the end of the pipe to prevent impurities from entering the pipe.
3. Pressure level and material
PVC pipe fittings have many pressure levels, common ones are PN4, PN6, PN10, etc., which are suitable for occasions with different pressure requirements. The material of the pipe fittings is generally PVC-U fittings, which have strong pressure resistance, corrosion resistance, and can withstand certain temperature changes.
Imperial size comparison
In some international standards, pipes and fittings are often expressed in imperial units. The correspondence between 75mm PVC pipe fittings and imperial pipe fittings can be converted by outer diameter size.
Size comparison of 75mm metric pipe fittings and imperial pipe fittings
75mm (metric) is equal to about 3 inches (imperial), that is, 3″ PVC pipe fittings.
Therefore, 75mm PVC pipe fittings and 3 inch pvc fittings are interchangeable in many cases, especially in international procurement or construction, where imperial and metric conversion may be required.
Common imperial pipe fitting sizes
1/2″: about 15mm
3/4″: about 20mm
1″: about 25mm
1 1/4″: about 32mm
1 1/2″: about 40mm
2″: about 50mm
3″: about 75mm
4″: about 100mm
In construction, imperial and metric sizes are often mixed, especially in multinational projects. It is very important to understand the conversion relationship between imperial and metric sizes.
Application fields
The application of 75mm PVC pipe fittings is very extensive, mainly involving water supply systems, drainage systems, industrial pipelines, agricultural irrigation and other fields.
1. Water supply system
75mm PVC pipe fittings are often used in medium-sized water supply systems, especially in water pipe systems in residential areas, commercial buildings, industrial parks and other areas. Due to the corrosion resistance and water pressure resistance of PVC pipe fittings, they can maintain stable performance during long-term water transportation. At the same time, the smooth inner wall of PVC pipes reduces water flow resistance and improves flow efficiency.
2. Drainage system
In building drainage systems, it is widely used to connect drainage pipes. It can effectively drain sewage, rainwater and other fluids into the drainage network to avoid water accumulation and leakage. The corrosion resistance of PVC pipes enables it to withstand long-term contact with sewage without being corroded.
3. Industrial pipelines
75mm PVC pipe fittings are also widely used in industrial applications, especially for the transportation of low-corrosive fluids. It can resist the corrosion of many chemicals and is particularly suitable for liquid transportation pipelines in industries such as chemical and food processing.
4. Agricultural irrigation
PVC pipe fittings also have important applications in agricultural irrigation systems. 75mm pipe fittings are often used in medium-sized farmland irrigation projects to ensure stable water flow and efficient distribution to various irrigation areas. The lightness of PVC pipes also makes installation and maintenance easier.
5. Power and communications industry
In the power and communication industries, it is used to protect cables. The cables pass through the PVC tube, which can effectively prevent the influence of the external environment (such as moisture, chemical corrosion, mechanical damage, etc.) on the cables and extend the service life of the cables.
75mm PVC pipe fittings have been widely used in many industries due to their standard specifications, good physical and chemical properties and wide applicability. Whether it is building water supply, drainage, or industrial pipelines, agricultural irrigation and other fields, they can be seen. At the same time, understanding the relationship between imperial and metric sizes is of great significance to the selection and installation of pipelines in multinational projects. With the continuous development of PVC pipe fitting technology, they will play a more important role in more fields in the future.
