90 Degree Fitting

A 90 degree fitting is a pipe or tube component that alters the direction of flow by 90 degrees. They are fundamental components in piping systems across numerous industries, enabling changes in direction while maintaining a consistent flow path.

Material

90 degree fittings are manufactured from a wide variety of materials, selected based on the application's pressure, temperature, and fluid compatibility requirements. Common materials include:

• PVC (Polyvinyl Chloride): Lightweight, corrosion-resistant, and cost-effective, suitable for low-pressure, non-critical applications like irrigation and drainage.
• CPVC (Chlorinated Polyvinyl Chloride): Offers higher temperature resistance than PVC, used in hot water distribution systems.
• PPR (Polypropylene Random): Common in plumbing, particularly for hot and cold water, known for its weldability and chemical resistance.
• Stainless Steel: Provides excellent corrosion resistance and strength, ideal for high-pressure, high-temperature, and sanitary applications (food processing, pharmaceuticals). Grades 304 and 316 are frequently used.
• Carbon Steel: Strong and durable, often used in industrial applications. Typically requires protective coatings to prevent corrosion.
• Brass: Corrosion-resistant and machinable, used in plumbing and gas lines.
• Copper: Excellent corrosion resistance and thermal conductivity, commonly used in plumbing and HVAC systems.
• Galvanized Steel: Carbon steel coated with zinc for corrosion protection, used in water and gas lines.
• Plastic (e.g., Polyethylene, Nylon): Used in low-pressure applications like irrigation and chemical transfer.

Purpose

The primary purpose of a 90 degree fitting is to change the direction of fluid flow by a right angle. This is crucial for navigating around obstacles, connecting components in confined spaces, and creating complex piping layouts.

Function

90 degree fittings function by providing a smooth transition in the flow path, minimizing turbulence and pressure drop. The internal geometry is designed to maintain flow efficiency while altering direction. Different connection types influence how the fitting is integrated into the overall system.

Usage Scenarios

• Plumbing: Connecting pipes under sinks, around toilets, and in wall cavities.
• HVAC: Connecting ductwork around corners and obstacles.
• Irrigation: Changing direction of water flow in sprinkler systems.
• Industrial Piping: Connecting pipes in process plants, chemical facilities, and manufacturing operations.
• Automotive: Used in fluid transfer systems (coolant, fuel, brake lines).
• Pneumatic Systems: Changing direction of airflow in compressed air lines.

Common Types

90 degree fittings are categorized by their connection method:

• Elbows: The most common type, available in various materials and connection types.
  • Slip Fittings: Allow for easy assembly and disassembly, suitable for applications where frequent maintenance is required.
  • Threaded Fittings: Connected using threads, providing a secure, leak-proof connection. Require thread sealant.
  • Socket Weld Fittings: Welded into place, providing a strong, permanent connection.
  • Butt Weld Fittings: Welded to the pipe ends, used in high-pressure, critical applications.
  • Compression Fittings: Use a compression ring to create a seal, suitable for smaller diameter pipes.
  • Push-to-Connect Fittings: Allow for quick and easy connection without tools.
• Long Radius Elbows: Feature a gradual bend, reducing turbulence and pressure drop compared to standard elbows. Used in applications where flow efficiency is critical.
• Short Radius Elbows: Feature a sharper bend, used in confined spaces where space is limited.
• Street Elbows: Have a threaded connection on both ends, used to change direction while connecting to a threaded pipe.
• Barbed Elbows: Used for connecting flexible tubing, commonly found in irrigation and low-pressure applications.

Based on the provided information, the declared goods, “90 degree fitting,” can be classified under the following HS codes:

• 7307.92.30.10: This HS code covers tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel: Other: Threaded elbows, bends and sleeves: Sleeves (couplings) Of iron or nonalloy steel. The first two digits, '73', indicate articles of iron or steel. '07' specifies tube or pipe fittings. '92' further defines other fittings. '30' denotes threaded elbows, bends, and sleeves, specifically those made of iron or nonalloy steel.
• 7307.92.30.30: This HS code covers tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel: Other: Threaded elbows, bends and sleeves: Sleeves (couplings) Of alloy steel (except stainless steel). Similar to the previous code, '73' represents articles of iron or steel, '07' signifies tube or pipe fittings, and '92' indicates other fittings. However, '30' specifies fittings made of alloy steel (excluding stainless steel).

Regarding HS codes 7307.92.30.10 and 7307.92.30.30, the total tax rate is 80.0%, comprising a 0.0% base tariff and a 25.0% additional tariff. Furthermore, a 30% additional tariff will be applied to steel and aluminum products starting from April 2, 2025. It is important to note that these fittings are subject to a 25% additional tariff on steel and aluminum products.
