In industrial piping systems, fittings, though small, often determine the stability and reliability of the entire system. Among them, 1 1 2 CPVC fittings (approximately DN40) are a key specification in small-to-medium diameter connection components, widely used in various industrial branch systems and equipment interfaces. As a brand specializing in the manufacture of high-performance plastic pipes and fittings, Junrui has accumulated extensive experience in the research, development, production, and engineering application of 1 1 2 CPVC fittings, enabling it to provide industrial customers with high-precision, high-reliability connection solutions.
The Value of 1-1/2 inch CPVC Fittings
In industrial piping networks, 1-1/2 inch fittings are a typical functional branch size, commonly used to connect key nodes between main pipes and terminal equipment. Compared to smaller diameter fittings (below 1 inch), they offer higher flow capacity; compared to 2-inch and larger sizes, they are more flexible and economical.
Their value lies primarily in:
High adaptability: Widely compatible with DN40 piping systems
Good flow and pressure balance: Suitable for medium flow conditions
Space-friendly installation: Facilitates construction in areas with dense equipment
Significant cost control advantages: Reduces system costs while meeting performance requirements
Therefore, 1-1/2 inch CPVC fittings are commonly used for equipment connections, branch conveying, and sophisticated control systems.
Performance Advantages of CPVC Material
1-1/2 inch CPVC pipe fittings are not only of suitable size, but their material properties also determine their wide application in industry:
1. Excellent High-Temperature Resistance
CPVC pipe fittings can withstand operating temperatures of around 90℃ for extended periods, making them suitable for hot water and high-temperature process systems.
2. Excellent Corrosion Resistance
They can resist various acids, alkalis, and chemical media, and are widely used in the chemical and water treatment industries.
3. High Connection Reliability
The adhesive bonding method provides strong sealing, effectively avoiding the risk of leakage.
4. Smooth Inner Wall, No Scaling
This helps maintain stable flow and reduces maintenance frequency.
