Product Description

Products Details

Grooved 45° Elbows are a special type of pipe fitting used in grooved piping systems. Grooved duct systems are known for their ease of installation and versatility. Groove design allows for quick, direct connections without soldering. Here is some information about fluted 45° elbows:

Features of grooved 45° elbow:
1. Materials: Grooved 45° elbows are typically made of ductile iron, stainless steel, or other materials suitable for the intended application. Specific materials may vary based on factors such as fluid type, environmental conditions and industry standards.
2. Groove design: The groove design can be easily assembled using couplings, washers and bolts. Grooves in pipes and fittings provide a secure and leak-proof connection.
3. Angle: The 45° angle of the elbow indicates the degree of change in the direction of fluid flow. It is typically used when a gradual change of direction is required.
4. Materials and standards: The materials and standards for grooved 45° elbows depend on the manufacturer and the specific requirements of the application.

Common materials include: Ductile Iron: Commonly used in water and wastewater applications. Stainless Steel: Suitable for corrosive environments or applications requiring higher corrosion resistance.

As for standards, products should meet industry standards, such as those set by organizations such as the American Water Works Association (AWWA) or the National Fire Protection Association (NFPA). Additionally, manufacturers may have their own product specifications.

Applications: Like other grooved pipe fittings, grooved 45° elbows can be used in a variety of industries, including:
1. Fire Protection Systems: Grooved duct systems are commonly used in fire protection applications due to their ease of installation and reliability.
2. HVAC Systems: In heating, ventilation, and air conditioning (HVAC) systems, grooved fittings are used to achieve efficient, quick connections.
3. Water and wastewater: Ductile iron grooved pipe fittings are commonly used in water and wastewater treatment plants.
4. Industrial piping: Grooved pipe fittings are used in industrial piping systems to transport various fluids.
Before selecting and installing a grooved 45° elbow, always consult the manufacturer’s specifications and guidelines to ensure proper compatibility with the intended application and compliance with industry standards and local codes.
