What is a Copper Tube?

Copper tube is often used to deliver hot and cold tap water, as well as a refrigerant line in HVAC systems. Soft copper tubing and rigid copper tubing are the two main types of copper tubing. A flare attachment, compression connection, or solder is used to join copper tubing. Copper tube is most widely used for a variety of industrial applications and is accredited to ensure a high level of quality and performance.

Manibhadra Fittings is one of the leading Copper Tubes manufacturers in India. Copper has a high resistance to corrosion, but it is becoming increasingly expensive. There are two types of copper tubes: rigid copper and soft copper. Copper tubes are most often used to supply cold or hot tap water, but they can also be used in HVAC systems as a refrigerant thread. Type L, Type DWV, Type K, and Type M are the most common thicknesses available for tubes made of copper in the United States and Canada.

Advantages of Copper Tube

We, Manibhadra Fittings are India’s best leading Copper Tube Manufacturer in India. Copper Tube also has the highest thermal conductivity of any heat exchange material.

Copper pipes have been used in plumbing for many years.
Some plumbers prefer working with copper because it’s easily installed and requires fewer tools during installation. Copper pipes are durable. They resist snapping and bacteria growth.
One of the main strengths of copper is that it won’t degrade in UV light.
Unlike plastic pipes which are only for indoor use, copper pipes can be used in areas exposed to natural light.

Calculated Rated Internal Working Pressures for Copper Tube: Type K

The rated internal working pressures of Copper Tube Type K are computed based on the wall thickness and diameter to ensure maximum safety and performance. Such pressures are very important for many applications, including plumbing, HVAC, and medical gas systems, where the integrity of the copper tube is vital under pressure conditions.
