Installation of copper pipes can be done in several ways.One of the most common - the use of soldering method of individual sections.This makes it possible to achieve tightness, but is not always practical because of the lower maximum pressure in the system.For heating or water supply is best applied flared copper tubes.
Appointment
essence of this process is to change the geometry of the end portion of the workpiece.It is necessary to connect different parts of the pipeline, followed by push-fit by pressing the junction.Device for expanding copper tubes has different parameters and depends on the diameter of the product, the wall thickness and the desired speed of execution of the procedure.
In order to understand the process, you can see the stages of its implementation.
- Training segments: trimming, grinding the cutting edge.
- Determination of larger outer diameter at the connecting portion of the pipe.
- With a special tool is a mechanical impact on the end of the preform, thereby increasing the inner diameter.
- installation resulting in another section of pipe socket.The compound is attached by soldering or crimping power tool.
When installing the piping, you can choose a model with ready mounting sockets or perform procedures for their own formation.
Prefabrication
If the length of the copper line is large and contains a large number of rotating parts, you can buy the product from the factory flare.For this use special rolls, made of high strength steel.After making its end portion of the tube is pressed by two rollers.The method of increasing the geometric dimensions of the rolling product in a certain part of it.
advantage of expanding the plant is complying with all the parameters of the pipe: wall thickness, length and diameter of the socket.However, the installation is often the size of the finished structures do not coincide with the required.This leads to an increase in sub-standard and scrap, as a consequence, a significant increase in costs for the purchase of materials.Therefore, for the laying of small arteries recommended tool for expanding copper tubes.
Forming roll yourself
When laying the pipeline air conditioning, plumbing or heating system with copper pipes need to use special tools.Before working should determine the diameter line.In this case, the flared copper tubes have to do yourself.
for water systems often use products with a cross section of 20 to 32 mm.If the heating system is set, the optimum diameter of from 32 to 40 mm, depending on the parameters of the boiler.For the installation of air conditioners used products up to 16 mm.
Accordingly, flaring copper tubes with your hands can be several types of instruments.The main criterion for choosing should be the quality of the socket and the ability to use interchangeable nozzles for pipes of different diameters.
tool
The easiest way to change the geometric dimensions of the end - use of the tapered cylinder of solid material.Its outer diameter must match the maximum value of the cross section of the future bell.
However, without a lot of practice possible occurrence of defects on the pipe walls.If you do the flared copper tubes with a large mechanical force than necessary, the result metal may crack.To prevent this, on the end cone is welded limiter.But this is not always a guarantee of the right of work.
An alternative method is to use a special tool - the expander.It is a cone head on which surface steps are arranged guides for pipes of different diameters.Press the lever socket expands uniformly to a desired level.
For a large amount of work with electric devices exist.The processes taking place in them automatically, which ensures a quality product.The main drawback is the price.
Advantages of
If you do the flared copper tubes alone, it is recommended to purchase a special tool.Use not intended for this device may lead to a significant deterioration of the joint.
advantages of professional rolling tool are as follows:
- uniform thinning of the walls as a result of mechanical action.
- open or strain on the pipe surface.
- speed of work will set the highway for a short time.
With a small amount of work necessary to buy a professional tool.Currently, there are many companies that provide rental service of rolling equipment for a small fee.
