Copper Pipe Cleaner
A copper pipe cleaner is a tool used for cleaning, shaping, and deburring the inside of copper pipes, primarily in plumbing, HVAC (heating, ventilation, and air conditioning), and refrigeration systems.
Material
Typically constructed from high-tensile steel wire wrapped with a copper strip or sleeve. The copper component provides a softer, non-abrasive surface to avoid damaging the pipe's interior while the steel core provides strength and rigidity. Some variations utilize solely copper wire for extremely delicate applications.
Purpose
The primary purposes of a copper pipe cleaner are:
- Cleaning: Removing oxidation, corrosion, and debris (like solder flux, oil, or dirt) from the inside of copper pipes before soldering, brazing, or flaring.
- Deburring: Removing sharp edges created when cutting copper pipes.
- Shaping: Slightly expanding or shaping the pipe's interior to facilitate fitting connections.
- Preparing for Swaging: Ensuring a smooth interior surface for swaging operations.
Function
The tool functions through a combination of mechanical abrasion and the malleability of copper. As the cleaner is inserted and rotated within the pipe, the copper strip conforms to the pipe’s inner surface, effectively removing contaminants. The steel core allows for the application of force to achieve a thorough cleaning.
Usage Scenarios
- Plumbing: Preparing copper pipes for joining in water supply lines, drain systems, and gas lines.
- HVAC/Refrigeration: Cleaning refrigerant lines before brazing or flaring, ensuring leak-tight connections.
- Automotive: Cleaning brake lines and fuel lines.
- DIY Projects: Used in various copper-based craft and repair applications.
Common Types
- Spiral Pipe Cleaners: These have a coiled wire design and are pushed through the pipe, expanding and contracting to clean the interior. Often used for longer runs of pipe.
- Brush-Type Pipe Cleaners: Feature copper bristles attached to a steel core. Effective for removing loose debris and corrosion.
- Chain Pipe Cleaners: Utilize a chain of copper links to scrape the interior surface. Suitable for heavily corroded pipes.
- Flexible Pipe Cleaners: Constructed with a more pliable steel core, allowing access to pipes with bends and tight angles.
- Specialty Cleaners: Designed for specific pipe diameters or applications, such as cleaners with abrasive pads for stubborn corrosion.
Based on the material, use, and application, “copper pipe cleaner” falls under articles of copper, specifically those used for household purposes.
Here are the relevant HS codes from the provided reference material:
- 7418100002: This HS code covers Table, kitchen or other household articles and parts thereof, of copper; pot scourers and scouring or polishing pads, gloves and the like, of copper; sanitary ware and parts thereof, of copper: Table, kitchen or other household articles and parts thereof; pot scourers and scouring or polishing pads, gloves and the like Pot scourers and scouring or polishing pads, gloves and the like: Of copper-zinc base alloys (brass). This includes household articles made of brass, which is a copper alloy. The tax rate is a base tariff of 3.0%, an additional tariff of 7.5%, and a further additional tariff of 30% after April 2, 2025, resulting in a total tariff of 40.5%.
- 7418100004: This HS code covers Table, kitchen or other household articles and parts thereof, of copper; pot scourers and scouring or polishing pads, gloves and the like, of copper; sanitary ware and parts thereof, of copper: Table, kitchen or other household articles and parts thereof; pot scourers and scouring or polishing pads, gloves and the like Pot scourers and scouring or polishing pads, gloves and the like: Other. This covers other household articles made of copper. The tax rate is a base tariff of 3.0%, an additional tariff of 7.5%, and a further additional tariff of 30% after April 2, 2025, resulting in a total tariff of 40.5%.
- 7419800900: This HS code covers Other articles of copper: Other: Cloth (including endless bands), grill and netting, of copper wire; expanded metal of copper: Other. If the copper pipe cleaner is manufactured from copper wire in the form of cloth or netting, this HS code may be applicable. The tax rate is a base tariff of 3.0%, an additional tariff of 25.0%, and a further additional tariff of 30% after April 2, 2025, resulting in a total tariff of 58.0%.
Important Note: The applicable HS code will depend on the specific composition and manufacturing process of the copper pipe cleaner. If the pipe cleaner is made of brass (copper-zinc alloy), HS code 7418100002 is most appropriate. If it is made of pure copper and falls under the category of "other" household articles, HS code 7418100004 would be used. If it is manufactured from copper wire as cloth or netting, HS code 7419800900 may be applicable.
