Types of 50mm copper pipe
A 50 mm copper pipe is highly suitable for numerous plumbing tasks. Copper pipes offer the ideal combination of strength and durability with resistance to corrosion to withstand extreme temperatures. This section looks at the most common types of 50 mm copper pipes based on the thickness of their walls and their applications.
Type K
This type has the thickest wall among all copper pipes. It is also the most expensive and hardest to bend due to its thickness. Its thickness means it is suitable for areas where copper pipes are buried underground or installed in walls out of sight. This pipe is suitable for long-lasting water supply lines in homes or public buildings.
Type K lumen copper pipe
This pipe comes with slightly thinner walls than type K but thicker than type M. In addition, this pipe is red, yellow, and blue color-coded along one edge for easy identification during installation. The resources help reduce waste and ensure the pipe is reused during future projects. Tye P-K pipe is suitable for medium-pressure situations and is often used in heating systems, irrigation, and industrial applications.
Type M
This copper pipe has the thinnest walls of all. It is also the cheapest and relatively easier to bend. The pipe can still be reused despite its thin walls, and it is often red, blue, and green colored along one edge to signify its thickness. This copper pipe is suitable for low-pressure decides and is often used in home plumbing systems and air conditioning.
Type DWV
As the name suggests, this copper pipe is designed for drainage, waste, and ventilation. This type has the thinnest walls, but it is not meant for transporting water through the lines under pressure. Instead, it is suitable for venting out waste lines where flexibility and light weight are required.
Specifications and features of 50mm copper pipe
Technical specifications
- Diameter: The outer diameter of a 50 mm copper pipe is 50 millimeters or 1.97 inches. The diameter of the pipe is critical since it determines the type and size of fittings that will be needed during installation, along with their compatibility with other plumbing and HVAC components.
- Thickness: Depending on the type of copper pipe, the wall thickness varies. For instance, type K pipe ranges from 2.24 to 4.38 mm, type P lumen pipe from 1.98 to 3.07 mm, type M pipe from 0.81 to 1.24 mm, and type DWV from 0.53 to 1.03 mm. Thicker walls offer greater durability in high-pressure situations.
- Length: Copper pipes are normally available in lengths of 2, 3, 4, and 5 m. The copper pipe can also be purchased in longer lengths and cut as per requirements. The longer the pipe, the easier it is for the plumber to install without joints.
- Weight: The weight of a 50 mm copper pipe depends on its length and the thickness of the wall. For instance, a type K copper pipe that's 1 m long weighs approximately 2.89 kg, type P lumen copper pipe 2.49 kg, type M pipe 1.34 kg, and type DWV 0.62 kg. The weight impacts the portability and ease of installation of the pipe.
- Working pressure: A 50 mm copper pipe has a working pressure of 1200 kPa, which is the pressure it can safely handle over an extended period without failure. Pressure decides the strength of the pipe when transporting water or gas. Higher-pressure copper pipes are suitable for more demanding tasks.
How to install
Follow these steps to install a 50 mm copper pipe:
- Measure and cut: Measure the length of the copper pipe required for the installation and mark the cut line with a permanent marker or chalk. Use a pipe cutter to make a clean, straight cut. Make sure the cut has no sharp edges.
- Clean: Use a cleaning brush or cloth to clean the edges of the cut copper pipe. To ensure a solid connection, apply flux to the joint area of the pipe and fitting.
- Heat: Use a propane torch to carefully heat the fitting until the soldering area is evenly heated. Don't overheat, as it may damage the copper or cause the flux to carbonize.
- Solder: Melt the solder into the joint's seam away from the flame. The solder flows where the flux is present to create a watertight seal. Ensure there's enough solder to form a solid bead around the joint.
- Let cool: Allow the joint to cool naturally for a few minutes. The flame used on the fitting must not be used near the joint.
- Inspection: After cooling, carefully check the joint to ensure the solder has evenly distributed around the joint. Inspect the pipe and fitting for signs of leakage before wrapping or covering the joint.
Maintenance and repair
- Check regularly: The copper pipe should be checked at least once a month for any signs of leaks, corrosion, or damage. The earlier possible issues are identified, the easier and less expensive they are to fix.
- Flush line: Occasionally, flush the copper pipes with water to remove any potential mineral buildup, sediment, or debris that may accumulate over time in the interior.
- Protect from corrosion: Ensure the section of the copper pipe exposed to the outside is coated with protective lacquer or paint to reduce the chance of corrosion.
- Repair leaks: When a leak is observed, repair it promptly. Soldering the joint or patching the pipe with a copper fitting can help fix minor leaks. For larger leaks, the section of the pipe may need to be replaced entirely.
Scenarios for 50mm copper pipe
A 50 mm copper pipe is used in commercial and residential buildings for plumbing, HVAC, refrigeration, and irrigation. This section explores the most common applications of a 50 mm copper pipe.
Water supply systems
A 50 mm copper pipe is used for the main water supply lines in residential and commercial buildings to deliver potable water. The 50 mm diameter is large enough to provide good water flow rates throughout the building or property. Copper is corrosion-resistant and durable so the pipe can be used underground, inside walls, or in exposed areas.
HVAC systems
In heating, ventilation, and air conditioning systems, a 50 mm copper pipe is used to transport refrigerant in cooling systems and the heat transfer fluid in heating systems. Copper is a better heat conductor than other materials, making it ideal for these applications. Because of its strength and flexibility, 50 mm diameter copper pipe is used to carry out the required temperature changes during the HVAC process.
Medical gas systems
Due to copper's durability and corrosion resistance, a 50 mm copper pipe is used to transport medical gases such as oxygen and nitrogen in healthcare settings like hospitals and clinics. Copper tubing is non-reactive and sterilizes easily, making it a safer option for transporting vital medical gases. Moreover, the 50 mm diameter is ideal for balanced flow rates of the gases.
Irrigation systems
Copper pipes are durable, corrosion-resistant, and long-lasting; thus, a 50 mm copper pipe is used in agricultural irrigation systems to deliver water to crops. Copper pipes help avoid contamination and ensure clean and safe water reaches the plants. Additionally, the 50 mm diameter provides optimal water flow rates for large agricultural areas.
