Copper Pipe Rolls for AC & Refrigeration | Wisdo Merchants

Copper Pipe Rolls for Air Conditioning and Refrigeration

Copper pipe rolls carry refrigerant between the indoor and outdoor parts of air conditioning and refrigeration systems. Copper tubing is the standard choice for this work. It moves heat well, resists corrosion and bends easily by hand or with a bender. At Wisdo Merchants in Nairobi, we supply copper pipe in seven sizes from 1/4″ to 7/8″. We serve AC technicians, refrigeration contractors and maintenance teams across Kenya.

Why Copper Pipe Is Used in Cooling Systems

Every split AC unit, cold room and refrigerator needs pipework to carry refrigerant around the system. That pipework has to hold pressure, stay leak-free and last for years. Copper does all three.

Copper is also easy to work with on site. You can cut it, bend it, flare it and braze it without special machinery. As a result, installers can fit the pipe neatly around walls, ceilings and tight corners. Rolled copper pipe needs fewer joints than straight lengths, and fewer joints mean fewer places for leaks.

Copper Pipe Rolls Features and Benefits

• Seven sizes in stock: 1/4″, 5/16″, 3/8″, 1/2″, 5/8″, 3/4″ and 7/8″ cover most AC and refrigeration jobs.
• 5.8 m length: Each roll is 5.8 metres long, so you can run a typical line set with fewer joints.
• Easy to bend: The soft rolled copper follows walls and corners without kinking when you bend it with care.
• Good heat transfer: Copper moves heat well, which helps cooling systems run efficiently.
• Corrosion resistant: Copper stands up well to moisture and humid conditions.
• Flare and braze ready: The pipe takes flare nuts and brazed joints, so it suits standard installation methods.

Technical Overview

Pipe sizes are given as outside diameters in inches. Always follow the equipment maker’s pipe size guide for liquid and suction lines.

Copper Pipe Rolls Applications and Installation Tips

Our copper pipe suits:

• Split and multi-split air conditioner installations
• Cold rooms, chillers and display fridges
• Commercial kitchens, supermarkets and hotels
• Repairs and line extensions on existing systems

Smaller sizes such as 1/4″ and 3/8″ are often used for liquid lines on split units. Larger sizes such as 5/8″, 3/4″ and 7/8″ usually serve suction lines and bigger commercial systems. For example, an installer fitting a split unit in an office usually runs a smaller liquid line alongside a larger suction line.

Installation tips:

1. First, measure the route and uncoil the pipe slowly to avoid kinks.
2. Next, cut the pipe cleanly with a refrigeration tube cutter and remove any burrs.
3. Then make your joints with a flaring tool kit, or braze them with a MAPP gas brazing torch.
4. After that, wrap the pipes with suitable pipe insulation to stop condensation and heat gain.
5. Finally, evacuate the system with a vacuum pump and check every joint with a refrigerant leak detector.

Safety and Handling

Keep the pipe ends capped until you use them, because dirt and moisture inside the pipe can damage the system. Uncoil and bend the pipe gently, since sharp bends can kink or flatten it. Cut ends can be sharp, so wear gloves.

When brazing, work in a ventilated area and keep flammable materials away. Wear eye protection and heat-resistant gloves. Only trained technicians should handle refrigerant and pressurised systems.
